Simple lifting equipment with hoisting mechanismonly commonly, to lifting weights. Simple structure, light weight, easy to carry,convenient to mo- ve Widely used in construction, bridge, road and railway construction, vehicle maintenance, ship maintenance and other departments. Is a typical use of hydraulic jacks hydraulic equipment to work through the manual pump to the hydraulic oil tank through the valve to the hydraulic cylinder piston from the bottom to the top of lifting heavy objects. Hydraulic transmission is using liquid as medium to transmit energy and control the transmission way, hydraulic transmission is put forward according to the 17th century PASCAL static pressure transmission principle of liquid developed new technology is a door in the technology industry and agriculture widely cited.It will be hydraulic energy into mechanical energy, use of the closed container body still rolling pressure to pass the same size as the surrounding properties, with output thrust a little big.【Keywords】 hand-pump, hydraulic cylinder,single direction valve,stop- valve ,tank,hydraulic drive 3
