Different models of claw jacks can withstand different types of gravity. Simply use their top or claws, shake the rocker, and lift heavy objects within a small range. The specific usage method is:

Place the pawl of the jack under the equipment, tighten the pressure relief valve, manually operate and continuously press the pressure pump to make close contact between the pawl of the jack and the bottom of the equipment, and then use a hand pressure rod to operate the jack. With the power support of the hydraulic oil inside the jack, slight manual labor can be used to adjust the height of the bulky equipment. After reaching the lifting position, use other tools to continue supporting the heavy object, manually release the pressure relief valve to slowly relax, and the lifting sleeve of the jack will gradually descend to the original position under the action of gravity.

Generally speaking, with reasonable and compliant operation, a high-quality claw jack can have a service life of up to 8-10 years.
