Floor jack is an important hydraulic component widely used in supporting the dead weight of equipment and adjusting the level of equipment on the heavy-duty vehicles or mobile equipment. It is mainly used in factories and mines, transportation departments as vehicles repair and other lifting, supporting and other work. Floor jacks use hydraulic oil, so how do you add hydraulic oil to floor jacks?

How to change oil with a floor jack?

(1) Find the rubber plug on the top of your body and dig it out

(2) Put the top flat and make the filling port upward.

(3) Refueling and pushing the piston to the bottom,

(4) Cover the rubber plug and finish the refueling.

Use floor jacks correctly

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.

How to maintain floor jacks?

1. The required pressure should be determined according to the actual situation (the manual pressure bar should not be longer)

2, the new or long-built hydraulic horizontal jack, because there is more air in the cylinder memory, at the beginning of use, the piston rod may appear tiny jump phenomenon, the hydraulic jack can be no-load reciprocating movement for 2-3 times, in order to eliminate the air in the cylinder

3. Clean the surface after use

4. Relieve pressure when not in use

5, the main maintenance is to replace the seal


Changing the oil of a floor jack is a simple matter. Learn how to change the oil of a floor jack in this article.

  • [Industry News] Working principle of hydraulic jack

    In principle, the hydraulic jack is based on Pascal principle, that is, the pressure of the liquid is the same everywhere, so in a balanced system, the pressure exerted on the smaller piston is relatively small, and the pressure exerted on the larger piston is also relatively large, which can keep t
