Working principle of lifting accessories

The working principle of lifting accessories mainly includes lifting principle, movement principle and stability principle.

‌Lifting principle‌: The lifting principle of lifting accessories mainly relies on mechanical, hydraulic or electric systems to drive the lifting mechanism to work. Common lifting mechanisms include wire ropes, chains, hydraulic cylinders, etc., through which the load can be raised or lowered in the vertical direction. The lifting principle of the crane is to convert the rotational motion of the motor into the linear motion of the lifting mechanism so that it can lift objects.

‌Moving principle‌: The moving principle of lifting accessories generally uses hydraulic or electric drive tires, chain rails and other components to move. The hydraulic system pushes the hydraulic oil into the hydraulic cylinder through the hydraulic pump to push the wheel forward or rotate; the electric system drives the tire or chain rail to move through the rotation of the motor. The moving principle of the crane is to convert electrical energy or pressure into mechanical energy through the control system to achieve the movement of the crane.

‌Stability principle‌: The stability principle of lifting accessories is to ensure that the crane remains stable and does not tilt during the lifting operation. Commonly used stability principles include outriggers, balance arms, center of gravity adjustment, etc. The outriggers are designed to increase the supporting area of ​​the crane and improve its stability. The balance arm balances the torque caused by the load to keep the crane in a balanced state. The center of gravity adjustment maintains the stability of the crane by changing the position of the sling or adjusting the center of gravity of the load.
