Hot Sale Auto Maintenance Jack 3ton for Auto Repair Lifting
Product description
The common hydraulic jack uses this principle to achieve force transmission. The screw jack pulls the handle in a reciprocating manner. Pulling the pawl pushes the ratchet clearance to rotate. The small bevel gear drives the large bevel gear to rotate the lifting screw, so that the lifting sleeve can be lifted or lowered to achieve the function of lifting tension, but it is not as simple as the hydraulic jack.
