Notes for floor jack use
Floor jack is with rigid jacking as working device, through the top bracket at the top of the small trip in light and small lifting weight lifting equipment, is a kind of widely used in load weight of vehicles or mobile devices supporting equipment and adjust the equipment level of an important hydraulic components, it is mainly used in mines, transportation and other departments as vehicle repair and other lifting, support, etc.
1, All parts must be checked before using the floor jack.
2, The main parameters should be strictly observed when using, avoid super overloading, otherwise when the lifting height or lifting tonnage exceeds the requirements, the top of the cylinder will have a serious oil leakage.
3, If the amount of oil in the manual pump body is insufficient, you need to add to the pump should be fully filtered after the hydraulic oil to work.
4, Please refer to the operation manual of electric pump.
5, The center of gravity of the weight to choose moderate, reasonable choice of the force point of the jack, the bottom to pad flat, at the same time to consider the ground soft and hard conditions, whether to liner tough wood, placed smoothly, so as to avoid weight subsidence or tilt.
6, After the hydraulic floor jack lifts the weight, the warehouse jack should timely use the support to support the weight firmly, it is prohibited to use the jack as a support. If heavy objects need to be supported for a long time, please choose.
7, If several floor jacks need to be lifted at the same time, in addition to the floor jacks should be placed correctly, also should use multi-jack shunt valve, and the load of each floor jacks should be balanced, pay attention to keep the lifting speed synchronization. It is also necessary to take into account the possibility that the ground may cave in due to uneven weight to prevent the weight being lifted from tilting and causing hazards.
8, When in use, first connect the quick joint of the manual pump to the top, then select the right position, tighten the oil discharge screw on the oil pump, and then it can work. To make the piston rod drop, loosen the hand pump wheel slightly counterclockwise and the cylinder will be unloaded. Then the piston rod will drop gradually. Otherwise it will be dangerous to fall too fast.
9, Separate jacks with spring return structure can be quickly removed after lifting, but do not use the connected hose to pull the jacks.
10, Because the floor jack lifting stroke is small, the user must not exceed the rated stroke when using, so as not to damage the hydraulic floor jack.
11, Violent vibration of floor jack should be avoided during use.
12, Not suitable for use in workplaces with acid, alkali and corrosive gases.
13, The user should check and maintain regularly according to the use condition.
1. Fix the car before repairing, so as not to cause damage to the car and people when the car skids during lifting. Fixed vehicles using the handbrake alone is not enough, the most secure method is to pull the handbrake while the manual transmission model into 1 or reverse, automatic transmission model after pulling the handbrake will be pushed to P.
2. The floor jack must be placed on the hard flat ground. If the car happens to be damaged in the soft ground or gravel, hard wood points can be used to ensure the supporting Angle of the jack under the jack.
3. The inside of the side skirt of each car has the support point of the jack parallel to the side skirt, which can be touched by hand. So when using the dry weight top, it must be supported on the special support point, which is made of steel plate with high strength. Other parts, such as the engine under the guard, suspension of the hem arm to avoid the support of the jack, due to its own strength is low, it is easy to cause unnecessary damage when slipping.
Through this article we can clearly understand how to use floor jacks to correctly and safely lift heavy objects higher.
A hydraulic shop press is a type of machine press that uses a cylinder in order to create a compressive force. The force of the shop press can be used for a variety of jobs such as clinching, moulding, forging and metalworking; it also has the ability to create a variety of intricate shapes for mo
