The main hoist steel wire rope of a gantry STS crane is crucial, specifically responsible for the vertical lifting of the spreader and container, and is one of the most critical load-bearing components of the entire machine.
It typically uses a multi-strand wound, flexible, and torsion-resistant wire rope model, effectively handling multiple layers of winding on the drum and frequent lifting impacts. It reliably bears and transmits enormous vertical loads, ensuring the stability and safety of containers during lifting and transportation. The rope groove is designed with soft padding and its dimensions are strictly controlled to minimize wire bending and extend service life.

The luffing steel wire rope of a gantry STS crane is the "muscle" specifically responsible for the horizontal extension and retraction of the boom. Its core tasks are traction and guidance. Through drums and pulley blocks, it drives the boom to change the horizontal extension distance (amplitude), allowing the crane to operate flexibly on the dock and ensuring efficient and safe cargo loading and unloading. Semi-anti-rotation wire ropes are usually used to prevent the rope from rotating during boom luffing, which could cause tangling or knots.

The trolley steel wire rope of a gantry STS crane is a key component that drives the trolley back and forth on the boom, enabling the horizontal movement of the load. Unlike load-bearing ropes such as hoisting ropes and luffing ropes, it primarily bears horizontal traction force. It commonly uses interlaced twist, which is resistant to torsion and less prone to loosening. Line contact is the most common, offering fatigue resistance and a long service life. Fiber cores or steel wire cores are frequently used, balancing lubrication and strength.
