The working principle of the hydraulic scissor lift is: under the control of the control system, the motor drives the work of the hydraulic pump, and the hydraulic pump converts the mechanical energy converted by the motor into the pressure energy of the liquid. The liquid acts on the hydraulic cylinder, and then the hydraulic cylinder is converted into mechanical energy and acts on the scissor mechanism. The mechanical energy is acted on the scissor lifting platform through the scissor mechanism, and finally converted into the potential energy or kinetic energy of the object, so as to realize the function of lifting or lowering people or heavy objects. The characteristics of scissor lift are: fast and stable working movement, large safety factor, light structure, low noise, good performance, easy maintenance, large load capacity, wide range of adaptation, and can realize jog control, etc. But at the same time, due to the use of hydraulic system, there are many control valve parts during installation, the oil circuit layout is more complicated, and the oil circuit is sometimes easy to leak under the action of high pressure, which makes the production cost relatively high
