Hydraulic jack, also known as hydraulic jack, is a kind of jack which adopts plunger or hydraulic cylinder as rigid jacking parts. Simple lifting equipment is generally only equipped with lifting mechanism for lifting heavy objects. Simple structure, light weight, easy to carry, easy to move. Commonly used simple lifting equipment hydraulic jack, pulley and hoist, etc. Hydraulic jack is divided into general and special. General hydraulic jacks are suitable for lifting operations with small lifting height. It consists of oil chamber 1, oil pump 2, oil storage chamber 3, piston 4, rocker 5, oil valve 6 and other main parts. When working, as long as the reciprocating pull crank, so that the manual oil pump constantly to the oil cylinder oil pressure, as a result of the increasing oil pressure in the cylinder, it forces the piston and the weight above the piston upward movement together. When the return valve is opened, the high-pressure oil in the cylinder flows back into the storage chamber, and the weight and the piston fall together. Special hydraulic jack is a special tensioning machine, which can exert tension on the prestressed steel bar when making prestressed concrete members. Most of the special hydraulic jacks are double-acting. Commonly used have wear a heart type and cone anchor type two kinds. The jack-through jack is suitable for tension steel bar or steel wire, it is mainly composed of tension cylinder, top pressure cylinder, top pressure piston and spring, etc. It is characterized by: along the axis of the stretching machine has a core hole, steel (or steel) through the end of the tool anchor anchorage. How it works (as shown in the figure). When tensioning, open the front and rear oil nozzles, supply oil from the rear oil nozzles to the tensioning oil chamber, and the tensioning cylinder moves backward. Since the cylinder cable is anchored to the tool anchor at the top of the jack, the jack extends the cable through the tool. When the cable is stretched to the required length, the oil nozzle is closed, and the oil is fed into the top pressure cylinder from the front nozzle, so that the piston of the top pressure cylinder moves forward against the anchor plug, and the anchor plug is pressed into the anchor ring, so that the cable is anchored. After opening the nozzle and continue to feed oil from the former nozzle, the tension cylinder moves forward and the oil in the cylinder flows back. Finally, open the front nozzle, so that the top pressure cylinder in the oil return, top pressure piston due to the role of the reset spring and return to the original position
