Electric hydraulic jack is a combination of hydraulic cylinder and electric pump station, which can realize various types of operations such as jacking, pushing, pulling, and extrusion.

The working principle of homemade electric jack

The most basic principle on which hydraulic transmission is based is the Pascal principle, that is, the pressure across the liquid is the same. In this way, in a balanced system, the pressure exerted on the smaller piston is smaller, and the larger piston is applied The pressure is also relatively large, which can keep the liquid still.

Therefore, through the transfer of liquid, different pressures on different ends can be obtained, so that a transformation can be achieved. The hydraulic electric jack that we commonly see uses this principle to achieve force transmission.

Use range of self-made electric jack

The Electric hydraulic jack are widely used in power maintenance, bridge repair, heavy lifting, static pile driving, foundation settlement, bridge and ship repair and construction, especially in road and railway construction, mechanical adjustment, equipment disassembly, etc.

How to use Electric hydraulic jack

Check whether each part is normal before use.Strictly abide by the provisions in the main parameters when using it, and avoid super high and overload, otherwise, when the lifting height or the lifting tonnage exceeds the specified, serious oil leakage will occur at the top of the electro-hydraulic jack.For electric pump, please refer to the manual of electric pump.


Heavy object

The center of gravity of the heavy object should be selected moderately, and the force point of the electric hydraulic jack should be selected reasonably, and the bottom surface should be leveled. At the same time, the soft and hard conditions of the ground should be considered, whether it should be lined with tough wood, and whether it is placed stably to avoid sinking or tilting of the load.After the electric hydraulic jack lifts the heavy object, the support should be used to support the heavy object in time. It is forbidden to use the ultra-high pressure large tonnage electric jack as a support. If you need to support heavy objects for a long time, please use self-locking jacks.If you need several electric hydraulic jacks to lift at the same time, please choose a synchronous jack.

In addition to the correct installation of the tonnage electric jack, a multi-jack diverter valve should be used, and the load of each large tonnage electric jack should be balanced, and pay attention to maintaining the lift Up speed synchronization. It must also be considered that the ground may sink due to uneven weight to prevent the weight being lifted from tilting and causing danger.

Avoid damage to the electric hydraulic jack

When using, first connect the quick connector of the hand pump with the top, then select the position, and tighten the oil drain screw on the oil pump to work. To lower the piston rod, loosen the hand wheel of the manual oil pump slightly in a counterclockwise direction, unload the oil cylinder, and the piston rod will gradually descend. Otherwise, the falling speed will be dangerous.

This electric jack is hydraulically retracted. After lifting, it can be quickly taken out, but the connected hose cannot be used to pull the ultra-high-pressure large-tonnage electric jack.The user must not exceed the rated stroke when using it to avoid damage to the electric hydraulic jack.Avoid violent jack vibration during use.Not suitable for use in workplaces with acid, alkali and corrosive gases.The user should check and maintain it regularly according to the usage. How to use the jackCheck whether each part is normal before use.

Several electric hydraulic jacks
