The large-tonnage hydraulic jack is a split-type synchronous jack, so you should pay attention when using the hydraulic unit. When using large-tonnage hydraulic jacks, the regulations in the main parameters should be strictly followed to avoid super high overload. Otherwise, when the lifting height or tonnage exceeds the specification, serious oil leakage will occur at the top of the cylinder.
The specific precautions for the use of large-tonnage hydraulic jacks are as follows: Before using large-tonnage hydraulic jacks, it is necessary to check whether the operation of each department is normal. The output force of the large-tonnage hydraulic jack hydraulic cylinder is proportional to the effective area of the piston and the pressure difference on both sides; the hydraulic cylinder is basically composed of a cylinder barrel and a cylinder head, a piston and a piston rod, a sealing device, a buffer device and an exhaust device .
The large-tonnage hydraulic jack is an executive element in the hydraulic transmission system and an energy conversion device that converts hydraulic energy into mechanical energy. If the amount of oil in the manual pump body is insufficient, the pump should be filled with fully filtered N33# hydraulic oil to work. Please refer to the instruction manual of the pump.
The weight selection should be moderate, and the center of gravity of the large-tonnage hydraulic jack should be reasonably selected and placed at the bottom. At the same time, it is necessary to consider the soft and hard conditions of the ground, whether to pad tough wood, place it stably, and avoid load sinking or tilting.
After the ultra-thin hydraulic jack lifts the heavy object, it should be firmly supported by the bracket in time. It is forbidden to use large tonnage hydraulic jacks as support. If you need to support heavy objects for a long time, choose the CLL self-locking hydraulic jack.
If several large-tonnage hydraulic jacks need to be lifted at the same time, in addition to the correct placement of the hydraulic jacks, multiple diverter valves should be used. The load of each large-tonnage hydraulic jack should be balanced, so that the lifting speed should be synchronized. It is also necessary to take into account the possible subsidence of the ground due to uneven weight, to prevent the danger from the tilting of the suspended heavy objects.
