Hot Sale Auto Maintenance Jack 3ton for Auto Repair Lifting

The jack is a safe and reliable lifting equipment, and generally there is no problem. The working medium of the jack is YB-N32 hydraulic oil. When the ambient temperature is lower than 10 ℃, YB-N22 hydraulic oil can be used, and when the ambient temperature is higher than 40 ℃, YB-N46 hydraulic oil can be used.

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.
