A quay crane is a common lifting equipment used for loading and unloading operations of general cargo or bulk cargo at ports, docks, warehouses, stacks, or within industrial areas, also known as a quay crane. The equipment is primarily composed of a power unit and a support structure. We have previously introduced the structure of its power unit, so now let's discuss the structure of its support part.

The pier crane consists of a main column and a rotating arm, composed of screw rods, jack nuts, and upright rods. The rotating arm can rotate 360 degrees on the main column, with a limit switch at the end arm to prevent overhoisting accidents caused by operational errors or button failure. The operation button starter can reverse the motor's direction, allowing the wire rope to be wound and unwound, and the object to be lifted or lowered using the pulley part of the bracket to complete the hoisting operation.
