33July 2017 cranes & access or crane. The product uses the ‘leverage’ and ‘grip or traction’ principal to allow the electric powered non-marking wheels to move such substantial loads. It features a two stage telescoping handle and weighs 75kg with battery. And if you need to move larger loads, combining additional units increases the capacity - ie two can move 50 tonnes, three 75 tonnes etc.Available in two versions - the cordless battery powered MTC 25 CC and mains powered MTC 25C - they use a 24 volt synchronous motor with one kilowatt power output providing smooth, continuous forward and reverse functions and emergency stop. The device uses an adaptor to connect to most steerable skates - such as German made GKS-Perfekt or Jung - and works like the kingpin of a tractor steering and manoeuvring (forward-reverse) a semi-trailer.Powered micro crane/lift Another new hand lift is the Powered Hand Truck from Australian company Makinex which has a maximum capacity of 140kg when working with the hook and 120kg with the fork attachment. It is designed to work on hard surfaces on slopes of up to three degrees. Other attachments include a vacuum lifter, panel lifter and sling. The unit can be folded flat when not in use and carried easily in a van or truck. The unit - which when lifting looks like a chicken wishbone - has a bottom frame with two travel wheels at one end with the handle with lift button and brake that the operator holds at the other. A long telescopic cylinder is connected centrally near the wheels to the moveable lifting arm which has a maximum lift of 1.9 metres. Power is supplied by an 18 volt battery pack.The range of different lifting equipment available or suited for industrial applications is continuously growing and evolving. Whether it involves lifting huge production machinery or just a small engine or pump, an ideal piece of equipment is sure to be available. It is not about the size of the equipment but finding the right tool for the job.clever design and improvements in technology have advanced to the point where battery electric industrial pick & carry, carry deck and spider cranes can perform as well as diesel powered models in terms of speeds, power and the ability to complete a full shift. Stricter manual handling regulations have also lead to the development of a burgeoning variety of smaller hand operated lifting machines, which are growing in popularity and spurring on further development.We have often highlighted the PowerAttack - an innovative lifting/skid tug which looks more like a powered broom handle but can move loads up to 25 tonnes using unpowered skates/dollies and is particularly useful in confined spaces in place of a fork lift truck The right tool forthe job industrial lifting c &a Each PowerAttack can more loads up to 25 tonnes Portable material loader Another interesting hand operated lifting product aimed at the smaller delivery sector is the Portable Self Loading fork lift from American company Innolift. The very clever product can self-load and unload items up to 600kg from the back of a van or truck and then operate in the same way as a walk behind material/fork lift. Maximum lift height is one metre. Once it has helped load the van it can load itself into the back, ready to unload the cargo at the next stop.Up and down the stairs Moving loads up and down stairs is another application that has spurred manufacturers to develop numerous innovative stair climbing cart solutions including rubber tracked carriers. CTE has developed and refined its product offerings in this sector with its Pianoplan 600J range of machines. The various models range from a standard transporter, to the Horizontal model that will maintain a level cargo deck while travelling up a flight of stairs and the Vertical model which will lift and tilt a large bulky load from the end then tilt it to the horizontal for the journey/steps and then raise it back to the upright position when in its final location. Maximum capacityover the pastfew years hascontinued a totaltransformation ofits product range,manufacturingfacilities anddistributionwith many of itsproducts ideal forindustrial lifting.(see Jekko on theMove story p50)Mast boom craneAs we have already seen, liftingand moving a load in an industrialsituation is more about finding theright tool for the job - irrespectiveof size. This year’s Vertikal Daysis 600kg on all three and overallweight of the machines runs from300kg for the standard model to345kg for the vertical.Off road tracked carriersWhen transporting larger loadsacross uneven ground the trackedcarrier - such as those seen onthe JT Cranes stand at this year’sVertikal Days and the 1,200kgcapacity Hoeflon TC1 - are ideal. JTCranes offers two remote controlcarriers with capacities of 4,000kgand 1,500kg and platform heightsof 570mm and 420mm respectively,ideal for moving loads when pickand carry is not an option.JT Cranes is the UK distributorfor Jekko, a company whichalso witnessed the UK debut ofanother unusual product - a mastboom industrial crane - fromGerman manufacturer HematecArbeitsbühnen. Hematec calls itsK 12500 a self-propelled assemblycrane with telescopic jib.&34cranes & access July 2017CTE’s Pianoplan hasa 600kg capacityand can travel up aflight of stairsA 1,200kgcapacity Hoeflon trackedcarrierWhatever its name it has a maximum tip height of 10.5 metres with a 500kg lift capacity, and a maximum radius of almost five metres with a 300kg load at a height of almost seven metres, or take 500kg to a radius of 3.6 metres. The machine can also slew or travel with its maximum capacity even when over the side. Overall width is just 980mm but the weight however is a fairly hefty 4.8 tonnes. Based on the company’s well proven Helix mast boom platform with a three section telescopic luffing jib in place of the basket, the unit is battery operated with direct electric drive and remote controls. The company has so far delivered 12 units to companies such as Audi, Bosch, Borbet, Mercedes-Benz and Volkswagen all of which appreciated its ability to work in restricted space conditions.Battery operatedcarry deck cranesWe reported last year ona new all battery electriccarry deck crane built bySouth Korean manufacturerHoryong and sold in theAmericas as the ZEE Crane.Two models are available- the 4.1 tonne 4500 andthe 8.2 tonne 9000 with a13.6 tonne version in theprototype phase. Poweredby dual battery packs theunits can be fully chargedovernight for an eight hourshift the following day.The 4500 weighs 3.6 tonnesand has a travel speed of 4.5 mph with two mph pick & carry speed. At 8.5metres the 4500 can lift 458kg. A 2.3 metre jib withzero, 25 and 50 degree offsets is available - ideal forrestricted space working - with an easy to changesingle to two fall hook block. Options include non-marking tyres, an in-house designed LMI with built-in diagnostics and a one man work platform.Another battery electric powered carry deck cranespotted at Conexpo in March is the BC-18, fromWisconsin-based Bailey Cranes with a maximumcapacity of 8.2 tonnes a three section boom with 14metre tip height. Pick & carry capacity is 5.3 tonnes.The American-made crane uses direct AC drivemotors for all functions and load sensing hydraulics.Options include a hybrid version and a three metrejib. Overall weight is just over nine tonnes.JMG expandsItalian crane manufacturer JMG Cranes is arelatively recent addition to the pick & carry cranemarket founded in 2007 by Maurizio Manzini, andjoining other Italian companies such as Ormig, Vallaand Galizia. Since then the company has unveileda number of innovations, including the first electricpick & carry crane with a Programmable LogicController in 2013, and the first narrow width -2,290mm wide - 45 tonne pick and carry cranein 2014. Last year the company acquired Lige -another small local industrial crane manufacturerwith 70 years experience - and this year addedthe new MC 580 battery operated electric pick &carry crane to its 17 model line-up, with a 58 tonnemaximum capacity.July 2017 cranes &The ZEE Crane 4500 during assembly Continued on page 49industrial lifting c&aThe MC 580 features a chunky four section, full power telescopic boom with boom nose mounted hook. The counterweight comprises four sections and an extendible wheelbase for additional capacity and greater stability. It has a fully equipped cab with radio remote joystick controls, a seven inch information screen, front wheel AC direct drive, rear 180 degree steer with counter rotating front wheels, allowing it to rotate on the spot through 360 degrees with full load on the hook. Options include a 30 tonne fork attachment, quick fit front levelling outriggers and a winch.Reedyk PC4405and Jekko MPK50 Another new industrial pick & carry crane is the compact Reedyk PC4405 from the Netherlands seen for the first time at Vertikal Days. The unit has been designed with an ATEX option for operating in areas exposed to explosion hazards. Equipped with a lithium ion battery pack, the crane is said to operate emission free for longer than one day on a single charge. The 30 degrees swivel boom assists accurate positioning and the PC4405 comes with a useful pick & carry deck. Maximum capacity is three tonnes, maximum lift height is nine metres with a maximum radius of 5.7 metres. The crane has a one metre overall width and weighs a relatively modest 2.8 tonnes. The PC4405 has an overall length of just2.4 metres with an overall height of1.8 metres.The PC4405 is a new breed ofpick & carry cranes similar toJekko’s remote controlled, batterypowered five tonne MPK50 MiniPicker, which offers a 9.5 metrelift height and a maximum radiusof 6.2 metres. The MPK50 hasan overall width of 1.2 metresand is three metres long. Overallweight is 3,450kg with the optionof a 1,000kg counterweight. TheJekko also has a two sectionmanually telescoped jib and offersfive degrees of slew either side ofcentre. A front stabiliser bar can beused to increase stability and liftcapacity. The Jekko Mini Pickersare pick & carry self-propelledbattery powered electric craneswith radio remote controls. Theycan also be used with Jekkohydraulic manipulators or vacuumlifters for handling and placingglass panels with options such aswinches, jibs, man platforms andlifting beams.The Hoeflon factorAnother mini crane company basedin the Netherlands and makinga concerted effort to expand itsproduct line and sales is Hoeflon. Itsrange now includes four mini cranesincluding the 600kg capacity minicrawler C1, and three spider cranes- the two tonne C4, the three tonneC6 and the four tonne capacity C10.With the range and sales increasingthe company is expanding andmoving to a new facility.HD forklift optionsAnyone needing an ultra heavy-duty‘lift & shift’ forklift cranes will havelooked at the Versa-Lift range ofmachines. The four model rangewas extended earlier this yearwith a new smaller model nowavailable. The 17/25 uses a slightlydifferent design which combinesthe wheelbase of a 6.8 tonnesolid tyre forklift with a moveablecounterweight that extends to therear by 914mm, rather than thewhole frame extending as is thecase with the rest of its range.Maximum capacity is 11.3 tonnesand the three section mast gives a3.7 metre lift height on the forks,which increases to just under sevenmetres when using the optionalboom attachment. Overall weight ofthe 17/25 is 13.6 tonnes.Skid steer crane attachmentOther weird and wonderful liftingdevices include the SkidCrane.Perhaps not primarily aimed at theindustrial lifting market, it is anattachment that converts a skidsteer loader into a unit capable oflifting up to 2.3 tonnes and up to13.1 metres. The SkidCrane is acompact hydraulically controlledcrane attachment that is easy toattach, use and transport and idealfor working in confined spacesparticularly on flat hard surfaces.Remote controls are also available.Earlier this year JMG added the new MC 580 battery operated electric pick & carry craneAnother new industrialpick & carry crane is thecompact Reedyk PC4405The SkidCraneis a compacthydraulicallycontrolled craneattachment for theskid steer loaderA Hoeflon crane in atight spotContinued from page 3549July 2017 cranes & access&50cranes & access July 2017Over the past few years Italian mini and spider crane manufacturer Jekko has been developing at a rapid pace. Cranes & Access caught up with chief executive Diego Tomasella at the opening of a new production hall to learn about the company’s latest developments.Five years ago, Jekko produced just 80 spider cranes a year however with annual growth of around 40 percent is it now forecasting shipments of 250 cranes this year - more than three times as many. However this is set to grow to 400 units a year over the next two years as production is further expanded.A new assembly facility has just opened located five kilometres from its headquarters in Colle Umberto to the north of Treviso, near Venice. Total area is 12,000 square metres - of which 3,900 square metres is covered - while much of the rest includes a large concrete yard. The old facility has been retained and is now used mainly for fabrication, while the new facility is purely an assembly hall with three production lines. Total investment is around €3 million.“The new facility allows us to increase production giving flexibility to cope with the increasing orders and improve the quality of the end product, particularly when one model is very much in demand,” says Tomasella. “Our new challenge with the rapid expansion of sales is the growth of the support within the company, particularly service and sales staff.”To maintain its growth Jekko has expanded its dealer network to 30 companies around the world, including China, Singapore, South Korea, Mexico, Colombia, the UK, Canada and USA. With Fassi taking a 33 percent stake in the company last year, there are several interesting new products including the new JF Jekko on the move tracked articulated loader cranes but also new lithium power packs for the spider and mini crawler cranes. However it is the tracked loader crane which the company thinks will be most popular range in five to 10 years time. Three models have been launched - the JF 545, the JF 30 and JF rgest is the 15.5 tonne capacity JF 545 with a six section main boom and six section jib, giving a maximum capacity of 600kg at 28.1 metres and a maximum lift height with 500kg of 30 metres. In transport mode the unit measures 5.45 metres long, 1.84 metres wide and 2.75 metres high, and weighs 15 tonnes. Outrigger spread is 6.7 metres square and the JF 545 offers a maximum radius of 10 metres at an up and over height of 18 metres. Power is supplied by a Kubota diesel, while options include an auxiliary electric motor, non-marking tracks and a two person 200kg platform with a 31.5 metre working height. Jekko says it has already booked 15 orders for the new JF 545’s. The other two tracked articulated loader cranes include the JF30 and JF40 which are similar in that they have maximum heights of eight and 8.1 metres and a maximum radius off 6.8 metres. Physically similar in size, the JF30 only has a lift capacity of 995kg so does not require a load moment limiter using a lift limiter on the winch. The JF40 has a maximum lift capacity of 2,500kg. Options on both include a 600kg capacity winch, electric power pack and remote control with two manual extensions on theJF30 and a single extension Jekko’s new facility will help boost production to 400 units per year over the next two years on the JF40. The JF 30 has an outrigger spread of 3.4 metres and weighs 1,400kg whereas the JF 40 has a four metre square spread and weighs 1,600kg. Both have a 2.4kph travel speed and gradeability of 20 degrees.“Jekko will not rank among the top two mini crane companies in the coming years, but we can keep pace with the competition,” says Tomasella. “Our goal has always been to come up with new ideas for the market. In a conservative market the smaller cranes can open doors.”New developments include a new colour scheme and decals from next year, the launch of a new MPK05, a new hydraulic jib for the SPX312 and a new nine tonne capacity SPK90 - the big brother of the SPK60.The 15.5 tonne capacity JF 545There are plans for a new nine tonne capacity SPK90 - the big brother of this SPK6051 July 2017 cranes & access。

注塑机螺杆的基本型号和主要参数注塑螺杆的基本型式及主要参数一般螺杆分为三段即加料段，压缩段，均化段。

加料段——底经较小，主要作用是输送原料给后段，因此主要是输送能力问题，参数（L1，h1），h1=（0．12－0．14）D。

压缩段——底经变化，主要作用是压实、熔融物料，建立压力。

参数压缩比ε=h1／h3及L2。

准确应以渐变度A=（h1－h3）／L2。

均化段（计量段）——将压缩段已熔物料定量定温地挤到螺杆最前端、参数（L3，h3），h3=（0．05－0．07）D。

对整条螺杆而言，参数L／D－长径比L／D利弊：L／D与转速n，是螺杆塑化能力及效果的重要因素，L／D大则物料在机筒里停留时间长，有利于塑化，同时压力流、漏流减少，提高了塑化能力，同时对温度分布要求较高的物料有利，但大之后，对制造装配使用上又有负面影响，一般L／D为（18～20），但目前有加大的趋势。

其它螺距S，螺旋升角φ=πDtgφ，一般D=S，则φ=17°40′。

φ对塑化能力有影响，一般来说φ大一些则输送速度快一些，因此，物料形状不同，其φ也有变化。

粉料可取φ=25°左右，圆柱料φ=17°左右，方块料φ=15°左右，但φ的不同，对加工而言，也比较困难，所以一般φ取17°40′。

棱宽e，对粘度小的物料而言，e尽量取大一些，太小易漏流，但太大会增加动力消耗，易过热，e=（0.08～0.12）D。

总而言之，在目前情况下，因缺乏必要的试验手段，对螺杆的设计并没有完整的设计手段。

大部分都要根据不同的物料性质，凭经验制订参数以满足不同的需要，各厂大致都一样。

下面就几种专用螺杆的设计结合其物料特性作简单介绍：一．PC料（聚碳酸酯）特点：①非结晶性塑料，无明显熔点，玻璃化温度140°～150℃，熔融温度215℃～225℃，成型温度250℃～320℃。

②粘度大，对温度较敏感，在正常加工温度范围内热稳定性较好，300℃长时停留基本不分解，超过340℃开始分解，粘度受剪切速率影响较小。

Box 4225Peterborough, Ontario, Canada, K9J 7B1Email:************************ABOUT THE TRANSDUCERThe ST-25C series of transducers operates in association with Milltronics ultrasonic level monitoring products.The transducer converts the electrical energy of the transmit pulse from the transceiver into acoustical energy. It then converts the acoustical energy of the echo back into electrical energy for the transceiver receive period.The effective acoustical energy is emitted from the transducer face and radiated outward, decreasing in amplitude at a rate inversely proportional to the square of the distance. Maximum power is radiated axially (perpendicular) from the transducer face in a line referred to as the axis of transmission. Where power is reduced by half (- 3 dB), a conical boundary defining the sound beam, centered about the axis of transmission is established. The diametric measurement of the cone in degrees defines the beam angle.Impedance matching techniques are used to optimize the transfer of power from the transducer into air and vice versa.SPECIFICATIONSModel :» ST-25CMeasurement range :» typically 0.3 - 7.5 m (1 - 25 ft)Environmental :» location:» indoor/outdoor » altitude:» 2000 m maximum» ambient temperature:» – 20 to 70 °C (– 5 to 158 °F)» pollution degree:» 4Supply source:» transducer shall only be supplied by Milltronics certified controllers Frequency :» typically 44 KHz Beam angle :» 12°Weight * :» 0.9 Kg (2 lb)Construction :» CPVC housing with polyurethane face » 1" NPT mounting/conduit connection » totally encapsulated» options: » flanging: » factory flanged, consult Milltronics» facing:» CPVC or Teflon for corrosive applications» polyethylene foam for dry-dusty applications Cable :» included:» 2- wire twisted pair / braided and foil shielded,18 AWG, neoprene jacket» extension:» 2- wire twisted pair / braided and foil shielded, 18 AWG,Maximum separation: 100 m (330 ft)» RG-62 A/U coax Maximum separation: 365 m (1200 ft) Approvals :» CE t , CSA, SAA, FM, BASEEFA / CENELEC* approximate weight of transducer with standard cable length and unflangedtEMC performance available upon requestTeflonis a registered trade mark of Dupont12° beam angleOUTLINE AND CONNECTIONDO’S AND DON’TSDo not route cable openly in raceways.For optimum isolation against electrical noise, run cable in a grounded metal conduit with no other cabling (except temperature sensor).

The cable must be protected against mechanical damage, and arrangements sealed to prevent migration of atmosphere from Zone 0.To reduce risk of electrostatic discharge, housing (except face) must be covered with copper mesh and grounded.connection via Milltronics w h t /s h b l k /h o t**When connecting to an EnviroRanger ERS 500, do not use coaxial cable;use a 2-wire extension as illustrated to the right.* Cable length: » standard:» 5 m (16 ft)» optional:» consult MilltronicsMOUNTINGDO’S AND DON’TSSpecial handling precautions must be taken to protect the face of the transducer from any damage.Mount the transducer so that it is above the maximum material level by at least the blanking value. Refer to the associated transceiver manual.Do not mount the transducer directly to metal. Use a PVC coupling and nipple as provided. Do not over tighten mounting. Hand tightening of the mounting hardware is sufficient.On liquid applications, the transducer must be mounted so that the axis of transmission is perpendicular to the liquid surface.On solids applications, the Milltronics Easy Aimer should be used to facilitate aiming of the transducer.Where the transducer is mounted to a standpipe, the inner standpipe surface and end must be smooth and free of burrs, ridges and seams.Consider the optional temperature sensor when mounting the transducer.MOUNTING - LIQUID APPLICATIONSHand Tighten ONLY!Flexible ConduitBracketPlywood mounting provides excellent isolation, but must be rigid enough to avoidflexing if subjected to loading.Submersible transducer,used in applications where flooding is possible.

To facilitate this mounting, it is suggested that the optional Milltronics Easy Aimer be used.APPLICATIONSThe transducer is to be used only in the manner outlined in this instruction manual.Normally, the transducer requires no maintenance or cleaning. However, if performance changes are observed, immediately shut down the level measurement system and perform a thorough inspection, especially on the transducer.LIQUID APPLICATIONS - STILLING WELL / OCMRefer to Liquid \ Applications - Standpipes.LIQUID APPLICATIONS - STANDPIPESIn many applications access must be made via a standpipe. In such cases, Milltronics can provide flange mounted transducers that will readily mate to the flanged standpipe. Another option is to hang the transducer from a blind flange.The standpipe length should be as short and the diameter as large as possible. As a rule of thumb, the -3dB cone of the sound beam should not intersect the standpipe wall in applications opening into a vessel or larger area. Otherwise, additional blanking will be required to compensate for the interference zone created by the opening.near blanking extensionof 150 mm (6") past end ofstandpipe may be requiredLIQUID APPLICATIONS - VOLUME1.Beam should not detect bin bottom. If this occurs use range extension parameters (on transceivers where available) to omit false echoes. A 12° beam angle represents a rise : run of about 10 : 1. In most tanks, the transducer should be centered as much as possible (without interference from inlet) for optimum reading range.2.Sound beam must be perpendicular to liquid surface.If standpipe is used, refer to Liquid / Applications - Standpipes.3.Echo has missed improperly leveled transducer.4.When performing an empty or full calibration, the tank must contain its normal vapour and be at its normal temperature.Empty level for "alternate" location.would reflect away tank manufacturer’s full levellevel has entered blanking zone.(shaded area)"Alternate""Preferred""Bad"dischargeLIQUID APPLICATIONS - WATER / WASTEWATERSEWAGE LIFTPUMP CONTROL5.
