The difference between hydraulic jack and mechanical jack is: different force, different advantages and different classification.

First, the intensity is different.

1. hydraulic jack: it is a jack that uses a plunger or a hydraulic cylinder as a rigid jack.

2. Mechanical jack: it is driven by manpower through screw pair, and the screw or nut sleeve is used as the jacking piece.

Second, the advantages are different.

1. hydraulic jack: it has the characteristics of compact structure, stable operation, large jacking force and self-locking.

2. Mechanical jack: light weight and easy to carry. Simple maintenance, safe and reliable use. Simple structure. It is an ideal large-tonnage mechanical jack with large lifting capacity.

Third, the classification is different.

1. Hydraulic jacks: divided into general hydraulic jacks and special hydraulic jacks.

2. Mechanical jack: divided into ordinary screw jack and self-falling screw jack.
