Vehicle mounted self-aid jack system

摘要

A jacking system mounted to a vehicle for selectively lifting up a portion of the vehicle relative to a ground, the jacking system includes two pairs of hydraulic jacks mounted to the vehicle, a hydraulic power assembly coupled in communication with the hydraulic jacks for providing a hydraulic fluid under pressure to selectively actuate the hydraulic jacks, and a control unit for activating a valve arrangement so as to selective shift each of the hydraulic jacks between a storage position and a load position, wherein at the load position, the fluid is pumped into hydraulic jack for lifting the vehicle, and at the storage position, the fluid is pumped into the hydraulic jacks from a reversing direction forcing the jack disengaged with the ground.
