SAFETY.READ THIS MANUAL BEFORE OPERATING THE JACK. FAILURE TO OBSERVE THE FOLLOWING WARNINGS COULD RESULT IN SERIOUS BODILY INJURY.∙Do Not position the jack by using theoperating lever in the release valve. If thejack is to be placed some distance underthe load, use the operating lever in theoperating lever/quadrant socket to positionthe jack.∙Do not attempt to exceed the rated load on the head or toe of the jack.∙The maximum working load and the travel of the hydraulic jack is marked on theequipment,∙In operation, never drop loads onto the jack. Always raise the head/toe to theload.∙Always ensure the full base area of the jack is supported when in use.∙Always ensure that loads are appliedcentrally to the ram, or to the full extent ofthe claw.∙DO NOT allow any persons to work under the load, when it is only supported byhydraulic jacks.∙Always clean the ram and retract it after use.∙Always remove the jack operating handle when not in use.∙Do not use if there is evidence of oilleakage.∙Never extend the ram by any means other than pumping the jack.∙Inspect and clean the jack after every use, but if subjected to abnormal or shockloading inspect for damage immediately. CHECKING THE OIL LEVEL.The jacks are normally supplied filled and ready for use. However before using the jack for the first time, the oil level should be checked. The oil used should be a high quality hydraulic oil of HVI ISO46 viscosity, e.g. Hi-force HFO32.Remove the dipstick (See figure 1) and check the oil level. The maximum level is marked on the dipstick. The level should be within 5mm of this mark. The dipstick should be screwed fully into position to determine this level.OPERATION OF JACK. See Figure 1.Note: The permissible working load and stroke of the Jack are marked on the side.The JAH series Jacks (1) have an in-built hydraulic pump which is worked by means of an operating lever (2), under the control of the operator. The piston (3) is raised on each downwards stroke of the lever. For lifting, the lever is placed fully into the operating quadrant (4). Three positions are provided to enable the user to choose the best ergonomic position. For lowering, the piston the lever is removed from the quadrant and placed into the release screw (5). Turning this anticlockwise will allow the piston to descend. The amount this is rotated will control the speed of decent. Only open a very small amount (approx. 5°) at first. Rotate clockwise, hand tight after use, to ready the jack for the next operation.JACKS WITH LOCKING COLLARS (TYPE SR)All models can be supplied with threaded pistons and locking collars to mechanically support the load without relying on the hydraulic circuit. When the load is at the required position, rotate the locking collar clockwise until it rest hand-tight on the top of the jack body.To undo – operate the jack so that the hydraulic circuit just takes the load of the locking collar. Rotate the collar anticlockwise until it reaches the top of the piston.JACKS WITH LIFTING CLAWS (TYPE C)Claws are supplied as an accessory to provide a low height lifting point. When fitted, lifting must always and only be carried out on the toe of the claw. See Figure 2.The capacity of the claw is 40% of the capacity of the jack to which it is fitted. Lifting claws must NOT be fitted to threaded piston jacks. Lifting claws must only be used with jacks having extended bases that extend under the toe of the claw. They must ONLY be used for vertical movements of loads.The recess on the underside of the top of the claw fits around the top of the piston. The heel of the claw rests against the front face of the jack. Ensure that the claw is seated properly before use and that the toe is as far under the load as possible.OPERATING POSITIONSThe Jack should be used in the two positions shown below, See Figure 3.Figure 3STROKE LIMITERPISTON STROKE LIMITING DEVICE:For Operator safety, all JAH jacks are factory-fitted with a fail-safe positive stop mechanism that prevents the over-stroking of the piston under loaded conditions beyond its maximum stated travel length. If the jack is operated in the over-stroke mode, oil is by-passed back to the reservoir to prevent the piston travelling further than its designed stroke distance.If pumping of the jack with the operating lever is continued with the piston in the over-stroke operation mode, some oil may by-pass the stop mechanism and appear at the top of the jack. If this occurs, cease operating the jack and wipe off any surplus oil.PLEASE NOTE: That if the over-stroke mechanism is operated and continuously pumped with the piston under no load conditions, insufficient pressure is achieved in the system to engage the by-pass system of oil to the reservoir, and within a short number of pumping actions, oil will appear at the top of the jack.OPERATING ENVIRONMENTThe jack is intended for use in industrial environments, in or outdoors between temperatures of -20 to +50°C. Outside these parameters, consult Hi-Force Ltd, before use.。

LSD3500A-300提升千斤顶作为LSD型液压提升设备中三大部分之一的主要承力部分,它以液压油为动力,推动油缸、活塞往复运动,通过上夹持器和下夹持器的荷载转换,从而实现垂直提升(或下降)重物的一种起吊设备。

二、主要技术参数
三、工作原理
提升千斤顶的上夹持器与千斤顶的活塞相连,下夹持器与油缸下部的撑脚相连,每台液压千斤顶共2个夹持器。

为使设备在带载下降作业时能开闭卡爪,每个夹持器包含了开爪油缸、夹片安装板和夹片螺钉。

通过液压泵站向提升千斤顶提供压力油,推动千斤顶活塞作伸、缩缸运动,伸缸时设置在活塞顶端的上夹持器卡紧承载钢绞线使提升重物随之一同向上移动,缩缸时与油缸相连的下夹持器卡紧承载钢绞线保证提升重物安全可靠的停留在新的位置,同时设置在活塞顶端的上夹持器放松承载钢绞线,活塞回程准备下一行程的提升。

当提升到位后,千斤顶活塞在近乎完全伸缸的位置处上夹持器卡紧承载钢绞线,下夹持器放松承载钢绞线,活塞缩缸带动重物下降。

在接近完全缩缸的位置处下夹持器卡紧承载钢绞线,上夹持器放松承载钢绞线后活塞空载伸缸,在近乎完全伸缸的位置处上夹持器再次卡紧承载钢绞线,下夹持器又放松承载钢绞线,如此依次循环直至提升重物准确的在设计位置就位。

液压千斤顶及泵站的液压回路上设置了液控单向阀和平衡阀,在遇到突然停电等突发事件是可对油路进行闭锁,使提升重物安全的悬挂在已定高度。

五、使用方法
1、液压千斤顶是提升动作的执行机构,其荷载为3500kN。

为穿心式结构,穿心孔径为Φ225。

撑脚的底部在与结构件成一体的横梁上固定。

同时要求千斤顶垂直安装。

装上接近开关、调整接近开关,使感应距离在3~5mm。

2、在进行系统管路、线路联接前需确定千斤顶的编号,然后按照油泵上标牌的标识进行联接。

3、安装构件(安全、导向)夹持器,构件夹持器的结构见下图,由锚板、压板与夹片组成,构件夹持器是联接承载钢索与提升重物的关键部件,构件夹持器与提升重物的连接方式可以是多样的,这需要在做方案时设计好。

构件夹持器的制作是吊装工艺中的重要工序,构件夹持器的制作质量的好坏对提升重物的就位有直接影响,组装时应特别仔细。

4、穿索前应将锚板上的锥孔擦净,然后在锥孔内均匀的抹上一层薄薄的退锚灵。

穿索时应仔细检查,使每根钢索在液压千斤顶的位置与构件夹持器锚板上的孔位一一对应。

不应错位、中间交叉、扭转。

每个锚孔中的三片夹片在安装时应使其成120°分布,安装到位后三片夹片的端部应平整。

当全部夹片安装完毕后,应及时安装压板并拧紧螺钉。

5、每个锚头做完后,必须立即与提升重物定位,防止构件夹持器打转。

安全夹持器的安装与构件夹持器的安装基本相同,但安全夹持器不需用压板压紧夹片,仅需拧上限位螺钉即可。

6、试吊时,当重物离地后应暂时悬停,再次检查构件夹持器观查其夹片是否松脱以保安全。

7、在液压千斤顶安装就位、穿索完成,在构件穿销挂装完成后,确认液压千斤顶上下夹持器已卡紧钢索后可松开导向夹持器,可用初预紧单孔锚卡紧钢索挂在2吨的手拉葫芦上对每根钢索进行预紧,加力20∽30kN。

如此反复多次轮流,使每根钢索受力均匀。

每根钢索预紧完,要用夹片逐根卡紧在导向夹持器上,然后卸下初预紧单孔锚。

当手拉葫芦预紧完成后,如有必要可使用YDC240Q千斤顶进行二次预紧,张拉油压取2∽4Mpa,张拉顺序为先内圈后外圈对称张拉。

完成钢索预紧后,可将外露的钢索伸出导向架。

当提升高度大时为避免导向架承载过大,应有一工作平台放置随提升而外伸的钢绞线。

如遇大风等恶劣天气,应用收线器将钢索的端部捆住以防钢索随风鞭击受损。

8、在控制提升千斤顶提升重物时,手动松上锚之前需先对该顶紧下锚,待下锚紧后缩缸约38mm(1#位~2#位间的距离),使上锚带松后方可松上锚;同理,手动松下锚之前需先对该顶紧上锚,待上锚紧后伸缸约38mm,使下锚带松后方可松下锚。

不可在上下锚未被带松前强行松上下锚。

只有当提升千斤顶处于安装或拆除状态时才可将千斤顶的上下锚均松开。

9、平时当提升千斤顶已穿钢索后,上下锚具必须有一个处于夹紧状态,不得同时松上、下锚具,以防堕落事故发生。

当某台千斤顶较长时间处于停止状态时,应将该顶的上下锚夹紧,以防堕落事故发生。

10、夹片的安装、使用与更换:夹片是LSD钢索式液压提升设备的关键承力部件,当千斤顶活塞往复运动时,夹片重复、交替地卡紧钢索而承受来自吊点的全部荷载。

在连续提升作业时,每次累计提升(或下降)5米后或出现“砰”、“砰”声时,应对上、下夹持器中夹片的锥形表面涂抹我厂提供的专用润滑脂(退锚灵)以提高夹片的使用寿命,切不可涂在钢索表面或夹片的牙面。

在吊装过程中,如出现“喀”、“喀”的响声时应及时停机检查夹片的工作情况,如发现夹片与钢绞线的咬合面磨损严重,必须更换夹片。

注意:只有在夹片卸载状态下,方能打开夹片更换夹片。

夹片安装时,应保证每付夹片上的三个导向螺钉的牢固性,拧紧后螺钉的外露高度一致。

六、注意事项
1、在吊装前应根据吊装对象,结合液压提升系统的特点作好吊装方
案及安全措施。

2、钢索导向架液压顶上方1.2米处能架设导向夹持器的安装板,以保证吐出的钢索在液压缸上方约1.5米的范围内始终保持垂直,导向架应能保证吐出的钢索的弯曲曲率半径要不小于1.2米。

同时导向架要有足够的强度、刚度,以承受吐出的全部钢索的重量。

必要时可在导向架上设置滚轮保持滚动磨擦,以减小阻力。

3、千斤顶使用的液压油要求使用32#(冬季)或46#(夏季),油的水份、灰份、酸性值应符合液压油的有关规定,油液必须经过反复过滤后方可使用,根据工作负荷的情况,3~6个月应更换一次油液。

液压油必须经过滤清,不同标号的液压油不能混合使用。

运行过程中,油温在150C~550C
4、各高压胶管连接时,其连接处必须用柴油清洗干净,以免将灰尘、杂质带入液压回路系统。

工作场地不允许有尖锐物,以防划伤高压胶管。

高压胶管及电气控制电缆应捆扎好,避免阻碍通行和施工作业时碰坏、砸断及大风刮落,确保安全施工。

5、提升吊装作业区内的电源线、高压油管,应不阻碍重物的提升,提升就位后方可将千斤顶卸荷,松脱。

6、油路连接时应保证同一液压泵站至各吊点提升千斤顶的油路长度等长、通径相等。

7、钢铰线不允许折皱。

8、设备中的液压泵站要由专人保管和维护。

使用人员应熟悉提升千斤顶结构及其动作程序。

9、经过使用,如发现泄漏或声音不正常,则应与制造厂联系或送专业厂家维修。

10、工作完成后拆卸油管时,应先使泵站内油压卸荷完,严禁带压力拔油管。

高压胶管拆除后,应戴上各接头盖或用塑料袋包好以免灰尘微粒、杂物进入胶管。

11、设备长期存放应将各部件擦净,并用塑料袋罩好。

若重新使用,则必须首先排除系统中积聚的空气,更换千斤顶中的易损件,检查提升千斤顶的动作是否正确。
