Packing list1.AbstractQJY3000 type Single-cylinder hydraulic jack is a new type of hydraulic driving inner-hold vehicle elevator equipment developed by our company recently.It is designed briefly and reasonably. It select hydraulic power unit and nylon roller with oil, having the merits of low noise, smooth rise-and-fall, simple maintenance and the unnecessary of daily lubricating oil.The machine has safety device which guards against falling, qualification equipment for ultimate load, lock equipment of revolution angle of lift arm, and no-pressure protection defending burst of oil pipe. It is the necessary elevator equipment in the vehicle industry.eThe machine can be used in elevating saloon car, beach wagon, business car and station wagon which have lower than 3000kg deadweight. It fixes them at operational height demandedn order to repair, service and clean.3.Profile4. Basic structure of product The machine mainly has double-pole, elevating oil cylinder, hydraulic power unit, elevating carriage, steel wire link gear, safety mechanism, equipment defending burst of oil pipe, and rotation-angle lock equipment of lift arm which all can be operated simply. When you push the switch on the electric motor of hydraulic power unit on the driving pole, the machine will rise. If you loosen, it will stop. High pressure oil driving piston rod in oil cylinder to elevate and chain and wire driving elevating carriage of major –minor poles to rise make workpiece rise. If you want to fall it down, you must pull the safety bracing plate of major –minor poles apart from the safety seat firstly, and open the handle bar on the hydraulic power unit. Gyration lift arm is telescopic and rotatable. Height of pallet can be adjusted in order to meet the different need of different kinds of vehicle. Our company can customize the machine with high pallet.5.

Safety device The machine has safety device guard against crack falling, no-pressure protection defending oil pipe overload, and revolution angle lock equipment of lift arm. Safety seat is designed on the major-minor poles. When lift pallet rise, safety bracing plate dragged by spring supports on the safety seat defending carriage falling. if the carriage would fall, opening the hydraulic pump switch make the carriage rise a little firstly. Then draw the unlocked line on the major-minor poles in order to draw safety bracing apart from safety seat. Last, open the pressure relief valve on the hydraulic pump to make the carriage fall. If the carriage fall caused by oil pipe burst happened, throttling gear works in order to defend the carriage fall suddenly. Lock devices are installed on the four lift arms in order to lock automatically at any angle work need. when carriage is at the bottom, lift arm can rotate freely.Safety service profile7. Installation and debuggingThe machine employs independent packing including major pole group, minor pole group, bed group, lift arm, hydraulic power unit and accessories(details as per attached list).Install process:(1) Put the bed on the fit place, fix the major and minor poles individually on the bed with M18X15, and direct minor pole rope to the square hole on the top of carriage through the bed. In order to install easily, we can make minor pole carriage up about 10mm with furring firstly and make it down after rope installing.(2).Hammer in expansion screws M16X140 after drilling a hole at concrete floor with Φ16 bit coaxial to the place of hole at bed. According to the situation of terrace, two pole should be placed vertically (maybe adjust using gasket). Last, screw home.(3).Place hydraulic power unit on the major pole, connect high-pressure pipe by screwing home without leak. Open the cover of oil bank and pour N46 hydraulic oil about 12L. Insert plug linked with electric wire of the pump in the socket preinstalled (electrical power must be installed shutdown switch). Push down the switch of electric machine to see if the carriage rise or not. if it doesn’t rise, switch the phase sequence to make oil pump work rightly and the carriage rise.(4).Guarantee the heights of the major and minor carriage. At the same time, judge the place of carriage by listening the safety bracing. Adjust again the nut of steel wire on the major carriage in order to guarantee that the carriages of major and minor are at the same plane.(5).Apply total excursion no-load running after the installation and debugging. During the rising, stop ,open pressure relief valve, and check the safety of major and minor carriage. Reopen ,stop again, draw individually the safety unhook wire of the major and minor carriage to make the bracing plate apart from safety seat, and open again the pressure relief valve to make the two carriages fall down. Apply total excursion load running and discharge the air in the oil tank at the same time. Carriage linked schematic plan:8.Matters need attention(1)Before lifting vehicle, we must adjust the height of four pallets toassure them at the same plane. At the same time, try to divide thelonger and the shorter lift arm into two sides in order to get thesupporting area gravity in the optimizer situation.(2)The lifted periphery and beam of vehicle must be placed correctlyon the center of the rubber pallet in order to make the gravity onthe center of supporting area. When the vehicle is lifted on theground about 100mm, stop rising, shake the vehicle and check thebracing. After all run correctly, we can rise it continually.(3)Strictly prohibit people under the vehicle during the lifting. Afterit arriving a stable height and in a safety situation, workers can goto operate under it.(4)Before falling down the vehicle, open the switch of electricmachine a little to make the carriage rise a little, then draw theunlocked line on the major-minor poles in order to draw safetybracing apart from safety seat. Last, open the pressure relief valveon the hydraulic pump to make the carriage fall. Special attentionmust be paid to see the major and minor can fall synchronously. Ifthey can’t, we must draw repeatedly until the vehicle fall well-balanced.(5)Pour N46 hydraulic oil or No.8 (winter), no.11 (summer) about12L into the oil tank of hydraulic pump. Change new hydraulic oilafter running half a year.(6)The machine use 220V electric source. During installing theelectric source, make sure to have reliable ground protection defending electric shock.(7)If meet accident, ask specialized persons repair or inform dealeror our company to have a check and obstacle avoidance. Becausesteel wire may become longer after using a period of time, adjustin time to make major and minor carriage be at the same height. 9.Electrical and hydraulic systemreturn10.
