Adjustment of rubber crawlerOpen the outside lid, adjust the bolts inside , see the figure below.ⅣUse and Operate Safely1.Safe Precautions1) The driver of the machine should earnestly implement the pilot performance, requirement for the novice to conduct specialized training, the failure of the driver can not drive the machine.2) It’s not allowed to start on high-speed, and it’s forbidden to down slope on the exercise of high-speed or neutral gear.3) The four legs must be put away steadily before the crane walk, plug the pin well, otherwise it’s fobidden to walk.4) You must ensure that the four legs are smoothly, and the four pins are inserted well before operate.5) The boom must be hoisted a certain height before rotation, in order to make sure that it can not encounter any legs and other parts.6) Regulate the undulate of the boom and decide the work radius. Please liftingaccording to the instructions provided by the weight load table below.This weight load table is for the legs are opened to maximize, please lower the weight rightly when the legs are not fully opened. Non-overweight!7) There are at least two persons at the scene when operating the crane. It is absolutely not allowed to stand under the boom.8) If it makes an odd sound in the course of working, you should immediately stop to inspect, please sovle the problem in time, and continue work after confirm that the state of the machine is normal.2. Safe warning signsThere are safe warning signs affixed in the appropriate place of the crane, in order to ensure the safety of using the crane, and remind the user, cause the user's attention. As following diagram:3. Basic OperationStart the engine after confirmed that the volume of hydraulic oil and gasoline are not less than 3 / 5 of the whole volume. (Conduct the warm-start when necessary in winter, about 15 minutes or so).Start the engineConfirm that you have put the gear shift lever in the position of neutralgap.(Confirm that there are no person or other obstacles on the driving directions).ForwardPull down the clutch, confirm the machine is separated from power, then operate the gear shift lever to shift. After the selection of the minimum forward speed, release the lever, and the crane begin to walk. Note that the crane begin to walk from low gear, do not open the accelerator too large at the beginning.TurnTwo lever located both sides of the middle lever are control the left and right direction of rotation respectively.When turning, you should use first gear.StopTurn down the accelerator when need to stop, pull the middle of the lever to inside, make sure the machine have separated from power.(The figure of lever as below)Attention: Do not place the lever in the middle position, unless it might turn off, or may accelerate suddenly on slope, it’s very dangerous. You must stop the crane on a most suitable location.Settings of Legs outstretchYou can extend the legs after you have confirmed the crane have stopped steadily. Tighten the four legs with the four levers. (See the figure of four levers as below)By hand, pull out the inside-pin near the fuselage, adjust to the most appropriate angel, then fix them. (The bigger angle of the leg, the smaller capacity of the load-bearing )(See the figure of the pin near fuselage as below)By hand, pull out the pin in the middle, choose right location, fix the pin. (Select the maximum angle in the situation of none obstructions generally.) (See the figure of the pin in the middle)By hand, pull out the front-end telescopic legs, fix the pin. (See the figure below: stretch out the front legs)Adjust the legs with lever, and stretch legs slowly until that the legs have been completely contact with the ground, and the fuselage are firmly fixed, you must regulate the level of the body by level. The angle of each leg should be consistently. Attention: Do not contact with buildings or other unstable places when operated. Stretch Leg 1and4 firstly and stretch Leg 2and3 secondly, thus it is easy to maintain a balance. Confirmed that the level is level. And it is appropriate that keep the distance between ground and the wheels is 10 centimeters.Operate the craneYou must operate in accordance with the following sequence strictly when lifting.①Boom ups and downs: operate the undulate handle of boom according to the icon ensure that the crane at a suitable location.②Rotating: operate the rotate handle according to the direction of rotation icon, ensure that the crane at a suitable location.③Telescopic: operate the telescopic handle according to the icon of stretching direction, ensure that the crane at a suitable location.④Hook ups and downs: Operate the undulate handle of hook according to the icon of the direction, ensure that the heavy at a suitable location.Attention: Make sure that the crane have hoisted a certain point of view, ensure that no encounter with any location of body and operator, and then rotate to adjust the corner, telescopic the boom, adjust the boom and hook according to the weight (Forbid standing under the boom)Operate sequence of the boom recovery:①Put away the crane hook ②Contract the boom ③Rotate the boom④Flat the boomAttention: You should confirm that the boom will not collide with any object after the rotationSet the back legsFirst of all, ensure that the crane have back to original position, and stall the gear in the neutral position, then close the first and the fourth leg a bit, ensure that the angle of the body tilt is not too great, and then close the second and the third leg, until that the track has contacted with the ground fully.Then put away the four hydraulic legs a certain angle (until it is suit to recover the small legs), firstly, withdraw the bottom of the legs, plug the pin, till to put away all the legs.Move the legs by hand, make sure they are close to the body, put them in the location by shown, compact the four legs a bit by the hydraulic. Insert the medial pin near thebody.ⅤCrane Maintenance1.Running maintenanceThe new machines or machines after overhaul must be running-in (test run, lifting), so as to avoid impacting the lifespan for abrasion of parts in advance.(1) The preparation before run.1) Clean the surface of the crane.2) Check and tighten bolts and nuts.3) Add enough lubrication oil in the parts needed according to the required.4) Fill up the engine tank and the hydraulic tank,(2) Running-in process1) Idling the engine 15min, starts from the low-speed, then accelerate gradually.2) Go forward on first gear or reverse gear, ensure that the walking is no problem.3) Set up the four legs and try to lift, ensure that there are no trouble. (Try not to lift heavy objects)4) In the course of test, try to observe whether exist abnormal sound or leakage, if any exception you should stop the machine immediately and rule out.2. LubricationLubrication is an important measure, it’s function is to ensure the normal operation of the machine, extend the mechanical life, improve efficiency and ensure the safety of operate. Maintainers should be fully aware of the importance of equipment lubrication, always check the conditions of lubrication about the motor point and filling lubricants (grease) to the lubrication point on a regular. Lubrication areas: the little and the big wheel and bearing in the reel bearing, hook pulley, fixed pulley, and other parts of rolling bearings, and other flexible pins in the operating system, decelerate gears, wire rope.Lubrication Note(1) Keep lubricants (grease) clean;(2)Adopt an appropriate lubricant (grease) or lubricate in required time (see the standard tables of lubrication);(3) Add the grease by pressure(gun or oil pump, screw-cap-style oil cups), so that push the grease on the friction surface to avoid that less grease approch the friction by wiping;(4) The rotating parts have no points of lubricate should be dripped dilute oile in the gap of each rotating pats regularly in order to reduce friction and prevent rust.(5) The rope must be lubricated on time and correctly. Clean the old oil with a rag soaked in kerosene before lubrication. Absolutely prohibit from using metal brush or other sharp utensils clean the dirt on the rope, but also the absolutely prohibit from using acidic or other lubricant has strong corrosive.3. Routine maintenanceAfter the class work, or operating, operator should do:(1) Test no-load, check the function of various institutions whether is normal, or exist abnormal noise.(2) Check the trip switch is complete and reliable.(3) Check the brake whether is reliable or not; ensure that the braking shoe has contacted with the brake wheel well and smooth; Ensure the gap is uniformity when release the brake shoe.(4) Check the rope on the reel and the pulley whether wound normal or not, whether exist the phenomena such as de-slot, string slot, knot, twist and so on.(5) Check the steel wire rope whether is wear or not, or exist broken wires, check the lubrication status of the steel wire rope.(6) Check whether there are obstacles on the track.(7) Ensure that the hook have fixed reliable, the rotating parts is flexible, and no cracks, no peeling, the anti-loose device of the nut on hook is finished.The high degree of wear on the dangerous section of the hook is no more than 5% of the original.(8) Check the sub-off device that prevent the rope slide from the pulley groove, the casing is intact, and there are no cracks in the pulleys, no defect on the rim.(9) Check the fasten on the metal structure and the transmission parts.(10) There are protective covers on the exposed moving parts are the possible.(11) Clean the crane regularly, and clean it weekly completely.4. First technical maintenanceInspect and maintain the crane once a month by the maintainer, except the contents about the routine maintenance, there also include:(1) Check the status of the abrasion about the bush should not exceed 50%, contact area of the gaskets and brake wheel should not be less at 70%; Check the status of the fixed pin about abrasion and lubrication.(2) Check whether all of the bolts are loosening and shortages.(3) Check the situation about bolts fastening on the base of the engine and the decelerator. Fasten them one by one.(4) Check the lubrication conditions of the decelerator, the oil level should be within the prescribed limits, you should take measures to prevent oil leakage in the permeable site.(5)Lubricate the gears.(6) Check the situation of abrasion about the rope pulley. Lubricate the pulley and the pulley shaft.(7) Check the situation of the pulley, such as flexible, have or not damage, cracks, pay attention particularly on the situation of abrasion about the fixed pulley.(8) Check the brake wheel, the degree of uneven about the work surface should not exceed 1.5mm, the brake wheel should not exist crack, and the radial run-out should be less than 0.3mm.(9) Check the operating conditions of the vehicle, ensure that there is not exist torsion phenomena when start and stop.(10) Lubricate the various parts of the crane.5.Second technical maintenanceInspect and maintain the crane once a month by maintainer, except the contents about the routine maintenance, there also include:(1) Check the situation of meshing and abrasion about all the gear in the accelerator and the pitting damage of the tooth surface should be not exceed 30% of the surface. , And the depth should be no more than 10% of the thickness of the original teeth (thickness of fixed string tooth); The abrasion loss of the gear tooth shall be not exceed 15% ~ 25% of the original thickness; Check the bearing condition; Replace the oil.(2) Check the position of the large and the small wheel, lubricate the wheel bearing.(3) Check whether the main seam welding of the main arm and the body is open or have corrosion phenomena, the rust should be not exceed 10% of the original thickness. And whether the major force components have fatigue cracks or not; , whether the stent and the variety of barriers are intact, check the bolts of the main beam and the end beam. tighten them again.(4) Check the deformation of the main beam and the situation of the car track. The interference of the main beam under no-load should be not exceed 1 / 2000 of the span; The bent of the main beam inward should be not exceed 1 / 1500 of the measurement length; The car track should not have the phenomenon of freeze. The abrasion loss of the track top and side (single-sided) should be not exceed 3mm. (5) Check the situation about the hoisting durm, the abrasion about the wall of hoisting drum should be not exceed 20% of the original thickness, the sharp peaks of the groove convex should not strain.(6)Tighten all the connections on the crane and fixing bolts.6. Crawler MaintenanceThe rubber crawler of the crane is an important component in the walking mechanism,but expensive. The life of the rubber depends largely on the operating environment and the usage. You must pay attention to the early prevention on the abrasion of the rubber crawler. The methods as follows:(1) Note the operating environment1) The rubber crawler should be avoided contacting with machine oil, diesel oil, grease and other oil. It also should be avoided contacting with acid, alkali, salt, and other chemical exposure. You should clean and clear it timely if that happen.2) The rubber crawler should be avoided sharp protruding stones, steel and other uneven road. When necessary, lay board or other flat objects.3) The rubber crawler should be avoided driving on the gravel surface for long distance, this can easily result in abrasion about the rubber surface early, it should be transferred by loaded vehicle if the traveling distance is far.(2) Master the usage correctly.1) The rubber crawler should be cleaned after used, to prevent the acceleration of abrasion and corrosion.2)You should reduce the sharp turn in the walking process, and it is easily damaged the crawler by off wheel caused by it, and it also bring about the guide wheel or the rail crash the core-iron, result in the core-iron drop off the core.3) Check the abrasion state of the wheel, driving wheels and support wheels regularly. It may enlarge the gap between the core iron and drive gear teeth when they meshing after the driving wheel is serious abrasion, generate a greater impact, iron core will be triggered when severely. And the serious abrasion driving wheel, guide wheel, supporting wheels, etc. should be replaced promptly.4)It should not be inclined to walk in slope; bridge walking; step walking by the edge of friction; forced to climb stairs walking. These are all abnormal driving patterns will lead to crawler damage, the iron core break, crawler edge cuts, steel cord injuries, etc. which abnormally damage will be produced.(3) Note that the adjustment of the tension degree about the rubber crawler.The rubber crawler must always be maintained a normal degree of tension. It can not be too loose or too tight. Tension too loose is easily to make crawler to derail, and the leading wheel, load wheel ride the gear. Tension too tight is easily to make crawler have a greater tension, leading to elongation, pitch change, bring about high-pressure side in certain locate, result in accelerate abrasion of the core iron and the driving wheel. You should always be careful to check and adjust in usage regularly. The adjustment should be on a flat hard surface (cement floor). Strut rack by hydraulic, release the tensioning nut of crawler, adjust the gap between load wheel and crawler to the required, then tighten the lock nut.。

Adjustment of V belt tensityIn order to achieve the adjustment of V belt tensity, you can adjust the tensity of the extension spring, which closely connected with the braced wheel.Check whether the tensity of the V belt is appropriate or not, and the length of two V belts should be almost equal, the method is pressing the middle of the belt with four fingers, and the V belts are depressed to15-20mm is appropriate.2. Adjustment of clutchYou can adjust the nuts connected the clutch cable and handle.3. Adjustment of brakeYou can adjust the nut connected the clutch cable and clutch.4. Adjustment of left-turn leverYou can adjust the nut connect the left-turn pull and handle.5. Adjustment of right-turn leverYou can adjust the nut connect the right-turn pull and handle.6. Adjustment of throttleThe role of the throttle is to adjust the engine speed. Make sure the engine achieve maximum speed, yet make the engine stall. Make sure the tightness of throttle is moderate, and it is difficult to turn the handle if the throttle is too tight, it is unable to stabilize a position if the handle too loose, thus affecting the speed of the engine. Adjust the length of the pull, whirl the throttle handle to the limit position clockwise, release the nut to adjust the length of pull, tighten the nut after adjust moderately.7. Adjustment of rubber crawlerOpen the outside lid, adjust the bolts inside , see the figure below.ⅣUse and Operate Safely1.Safe Precautions1) The driver of the machine should earnestly implement the pilot performance, requirement for the novice to conduct specialized training, the failure of the driver can not drive the machine.2) It’s not allowed to start on high-speed, and it’s forbidden to down slope on the exercise of high-speed or neutral gear.3) The four legs must be put away steadily before the crane walk, plug the pin well, otherwise it’s fobidden to walk.4) You must ensure that the four legs are smoothly, and the four pins are inserted well before operate.5) The boom must be hoisted a certain height before rotation, in order to make sure that it can not encounter any legs and other parts.6) Regulate the undulate of the boom and decide the work radius. Please lifting according to the instructions provided by the weight load table below.This weight load table is for the legs are opened to maximize, please lower the weight rightly when the legs are not fully opened. Non-overweight!7) There are at least two persons at the scene when operating the crane. It is absolutely not allowed to stand under the boom.8) If it makes an odd sound in the course of working, you should immediately stop to inspect, please sovle the problem in time, and continue work after confirm that the state of the machine is normal.2. Safe warning signsThere are safe warning signs affixed in the appropriate place of the crane, in order to ensure the safety of using the crane, and remind the user, cause the user's attention. As following diagram:3. Basic OperationStart the engine after confirmed that the volume of hydraulic oil and gasoline are not less than 3 / 5 of the whole volume. (Conduct the warm-start when necessary in winter, about 15 minutes or so).Start the engineConfirm that you have put the gear shift lever in the position of neutralgap.(Confirm that there are no person or other obstacles on the driving directions).ForwardPull down the clutch, confirm the machine is separated from power, then operate the gear shift lever to shift. After the selection of the minimum forward speed, release the lever, and the crane begin to walk. Note that the crane begin to walk from low gear, do not open the accelerator too large at the beginning.TurnTwo lever located both sides of the middle lever are control the left and right direction of rotation respectively.When turning, you should use first gear.StopTurn down the accelerator when need to stop, pull the middle of the lever to inside, make sure the machine have separated from power.(The figure of lever as below)Attention: Do not place the lever in the middle position, unless it might turn off, or may accelerate suddenly on slope, it’s very dangerous. You must stop the crane on a most suitable location.Settings of Legs outstretchYou can extend the legs after you have confirmed the crane have stopped steadily. Tighten the four legs with the four levers. (See the figure of four levers as below)By hand, pull out the inside-pin near the fuselage, adjust to the most appropriate angel, then fix them. (The bigger angle of the leg, the smaller capacity of the load-bearing )(See the figure of the pin near fuselage as below)By hand, pull out the pin in the middle, choose right location, fix the pin. (Select the maximum angle in the situation of none obstructions generally.) (See the figure of the pin in the middle)By hand, pull out the front-end telescopic legs, fix the pin. (See the figure below: stretch out the front legs)Adjust the legs with lever, and stretch legs slowly until that the legs have been completely contact with the ground, and the fuselage are firmly fixed, you must regulate the level of the body by level. The angle of each leg should be consistently. Attention: Do not contact with buildings or other unstable places when operated. Stretch Leg 1and4 firstly and stretch Leg 2and3 secondly, thus it is easy to maintain a balance. Confirmed that the level is level. And it is appropriate that keep the distance between ground and the wheels is 10 centimeters.Operate the craneYou must operate in accordance with the following sequence strictly when lifting.①Boom ups and downs: operate the undulate handle of boom according to the icon ensure that the crane at a suitable location.②Rotating: operate the rotate handle according to the direction of rotation icon, ensure that the crane at a suitable location.③Telescopic:operate the telescopic handle according to the icon of stretching direction, ensure that the crane at a suitable location.④Hook ups and downs: Operate the undulate handle of hook according to the icon of the direction, ensure that the heavy at a suitable location.Attention: Make sure that the crane have hoisted a certain point of view, ensurethat no encounter with any location of body and operator, and then rotate to adjust the corner, telescopic the boom, adjust the boom and hook according to the weight (Forbid standing under the boom)Operate sequence of the boom recovery:①Put away the crane hook ②Contract the boom ③Rotate the boom④Flat the boomAttention: You should confirm that the boom will not collide with any object after the rotationSet the back legsFirst of all, ensure that the crane have back to original position, and stall the gear in the neutral position, then close the first and the fourth leg a bit, ensure that the angle of the body tilt is not too great, and then close the second and the third leg, until that the track has contacted with the ground fully.Then put away the four hydraulic legs a certain angle (until it is suit to recover the small legs), firstly, withdraw the bottom of the legs, plug the pin, till to put away all the legs.Move the legs by hand, make sure they are close to the body, put them in the location by shown, compact the four legs a bit by the hydraulic. Insert the medial pin near the body.ⅤCrane Maintenance1.Running maintenanceThe new machines or machines after overhaul must be running-in (test run, lifting), so as to avoid impacting the lifespan for abrasion of parts in advance.(1) The preparation before run.1) Clean the surface of the crane.2) Check and tighten bolts and nuts.3) Add enough lubrication oil in the parts needed according to the required.4) Fill up the engine tank and the hydraulic tank,(2) Running-in process1) Idling the engine 15min, starts from the low-speed, then accelerate gradually.2) Go forward on first gear or reverse gear, ensure that the walking is no problem.3) Set up the four legs and try to lift, ensure that there are no trouble. (Try not to lift heavy objects)4) In the course of test, try to observe whether exist abnormal sound or leakage, if any exception you should stop the machine immediately and rule out.2.

The abrasion loss of the track top and side (single-sided) should be not exceed 3mm. (5) Check the situation about the hoisting durm, the abrasion about the wall of hoisting drum should be not exceed 20% of the original thickness, the sharp peaks of the groove convex should not strain.(6)Tighten all the connections on the crane and fixing bolts.6. Crawler MaintenanceThe rubber crawler of the crane is an important component in the walking mechanism, but expensive. The life of the rubber depends largely on the operating environment and the usage. You must pay attention to the early prevention on theabrasion of the rubber crawler. The methods as follows:(1) Note the operating environment1) The rubber crawler should be avoided contacting with machine oil, diesel oil, grease and other oil. It also should be avoided contacting with acid, alkali, salt, and other chemical exposure. You should clean and clear it timely if that happen.2) The rubber crawler should be avoided sharp protruding stones, steel and other uneven road. When necessary, lay board or other flat objects.3) The rubber crawler should be avoided driving on the gravel surface for long distance, this can easily result in abrasion about the rubber surface early, it should be transferred by loaded vehicle if the traveling distance is far.(2) Master the usage correctly.1) The rubber crawler should be cleaned after used, to prevent the acceleration of abrasion and corrosion.2)You should reduce the sharp turn in the walking process, and it is easily damaged the crawler by off wheel caused by it, and it also bring about the guide wheel or the rail crash the core-iron, result in the core-iron drop off the core.3) Check the abrasion state of the wheel, driving wheels and support wheels regularly. It may enlarge the gap between the core iron and drive gear teeth when they meshing after the driving wheel is serious abrasion, generate a greater impact, iron core will be triggered when severely. And the serious abrasion driving wheel, guide wheel, supporting wheels, etc. should be replaced promptly.4)It should not be inclined to walk in slope; bridge walking; step walking by the edge of friction; forced to climb stairs walking. These are all abnormal driving patterns will lead to crawler damage, the iron core break, crawler edge cuts, steel cord injuries, etc. which abnormally damage will be produced.(3) Note that the adjustment of the tension degree about the rubber crawler.The rubber crawler must always be maintained a normal degree of tension. It can not be too loose or too tight. Tension too loose is easily to make crawler to derail, and the leading wheel, load wheel ride the gear. Tension too tight is easily to make crawler have a greater tension, leading to elongation, pitch change, bring about high-pressure side in certain locate, result in accelerate abrasion of the core iron and the driving wheel. You should always be careful to check and adjust in usage regularly. The adjustment should be on a flat hard surface (cement floor). Strut rack by hydraulic, release the tensioning nut of crawler, adjust the gap between load wheel and crawler to the required, then tighten the lock nut.。
