Structural principle of scissor lift

The Scissor Lift is a kind of scissor lift mechanism made of rectangular steel pipe or steel plate as the scissor support. It is a mechanical equipment that drives the opening and closing of the scissor support through the expansion and contraction of the hydraulic oil cylinder, rigid chain and large spiral drive system to achieve the lifting movement. The rise and fall of the scissor lift structural principle are based on the stable movement of the support drive system, with high safety and wide use.




Fixed scissor lift




Structural principle of scissor lift: the scissor type steel frame is mainly used as the lifting guide mechanism, which is usually driven by hydraulic power. Many users do not understand the scissor type lifting and structural principle. It is a widely used high-altitude operation and large tonnage cargo lifting equipment. The hydraulic driven scissor lift structure is composed of frame, hydraulic system and electrical parts. It is equipped with limit device, lift self-locking protection device, etc. to ensure the safe use of the lift and the life safety of maintenance workers. The elevator is controlled by the electrical system. The hydraulic system outputs hydraulic oil as power to drive the piston rod to retract and drive the boom to rise, fall and lock.




Self propelled scissor lift




The cost of hydraulic driven scissor type structure is relatively low, and the load capacity is also large enough. However, due to the limitation of hydraulic fittings, it is not appropriate to make models with high speed requirements. If models with high speed or high speed requirements are required, rigid chain drive or large screw drive should be used.




Crawler elevator




Scissor type elevators are generally divided into mobile, fixed, traction, self-propelled, crawler type, etc. They are used in different fields, such as mobile and traction type elevators, which can be directly towed for outdoor high-altitude operations, fixed type elevators are suitable for lifting large tonnage goods, self-propelled elevators are suitable for interior decoration, fire pipeline erection, etc.
