Hoist Cylinders is divided into four parts: 1. The power part - converts the mechanical energy of the prime mover into the pressure energy of oil (hydraulic energy). 2. The execution part - converts the oil pressure energy input by the hydraulic pump into the mechanical energy that drives the working mechanism. 3, control part - used to control and adjust the oil pressure, flow and flow direction. 4, auxiliary part - the first three parts are connected together to form a system, which plays the role of oil storage, filtration, measurement and sealing.
