The screw jack has the advantages of small size, large strength, labor saving, high quality, good quality, durability, and strong environmental adaptability. It is the manpower that achieves the lifting purpose through the cooperation between the transmission of the screw pair, the screw and the nut sleeve. Its main purpose is in mechanical maintenance.
The hydraulic jack has the advantages of low labor saving, large lifting capacity, compact structure, stable work, strong bearing capacity and convenient movement. It only needs to repeatedly pull the handle when working, so that the manual oil pump continuously presses the oil into the cylinder, due to the oil pressure in the cylinder. The rise of the piston forces the piston and the weight above the piston to move upward together. When the oil return valve is opened, the high-pressure oil in the oil cylinder flows back to the oil storage chamber, so that the heavy object and the piston also fall together. Hydraulic jacks are widely used in the lifting work of bridges, docks, factory warehouses, construction projects, transportation and other industries.
