Problems needing attention when using hydraulic jack:

1: Hydraulic Jack in lifting operation, to choose the appropriate tonnage of hydraulic jack: load-bearing capacity can not be overloaded, the choice of hydraulic jack load-bearing capacity needs to be greater than 1.2 times the weight of gravity; Hydraulic Jack minimum height is appropriate, in order to facilitate removal, choose the minimum height of hydraulic jack should be applied to the bottom of the weight. When the pillow supports heavy objects during landing, the lifting height of the hydraulic jack is larger than the sum of the thickness of the pillow and the deformation of the pillow.

 

2: If multiple hydraulic jacks are used to lift the same equipment, the same type of hydraulic jack should be selected, and the sum of rated lifting weight of each hydraulic jack should not be less than 1.5 times the weight of the equipment.

 

3: Hydraulic Jack should be wiped clean before use, and should check whether the components are flexible and non-destructive. When there is load, do not unload the quick joint, in order to avoid accidents and damage parts.

 

4: Hydraulic jacks should be laid flat before use, not inclined, the bottom should be padded flat, strictly prevent the foundation from sinking or load migration and make hydraulic jacks inclined or toppled, can be padded at the bottom of hydraulic jacks with tough pillows or steel plates to expand the bearing area, so as to avoid accidents caused by sinking or sliding; do not use oily wood or plate. The steel plate is used as the backing to prevent slippage and safety accidents. The lifting position of heavy objects must be a safe and solid part in order to prevent damage to equipment.

 

5: When using hydraulic jack, first try to lift a part of the weight, carefully check that there is no abnormal hydraulic jack, then continue to lift the weight. If it is found that the cushion plate is uneven, unstable or the hydraulic jack is inclined, the hydraulic jack must be relieved and returned to work in time before it can be operated again.
