STS Quay Crane is a specialized lifting equipment for loading and unloading container ships at the front of container terminals. And its function is to unload containers from the ship directly onto the quay, or from the quay onto the ship. The design, manufacture and inspection comply with international standards such as FEM, DIN, IEC, AWS and GB. Quay crane mainly consists of electrical control system, metal structure. It also includes four major mechanisms, hoisting mechanism, trolley running, pitching mechanism and trolley assembly. Besides, it also equips hanging cabin protection device and auxiliary devices. Each organization adopts all-digital AC frequency conversion, PLC control speed regulation technology, flexible control, high precision.
Our quay crane also has various specifications of single and double containers special spreader and optional electronic anti-shaking function. The main lifting capacity specifications are 35 ton, 41 ton, 51 ton, 65 ton. STS quay cranes have a number of leading technologies, the use of variable frequency multi-feedback technology. It has superior performance, large lifting capacity, long reach and real-time collection of operating position information. This quay crane also uses intelligent control of the spreader, perfect safety protection features, so it presents high efficiency, energy saving and environmental protection.

1. Vector frequency conversion, power feedback, torque balance control technology, energy saving and environmental protection, convenient and efficient;
2. Distributed bus control, fiber optic communication, anti-interference, high stability;
3. Intelligent service management system, real-time monitoring of each operating status of the equipment;
4. Automatic fault detection and real-time data display technology, safe and reliable;
