Quayside Container STS Crane

Description of Quay Crane

Quayside container crane (referred to as STS bridges) is one key equipment used by port terminals to load and unload containers. Its superstructure mainly includes main girder, lifting mechanism and trolley system. The main girder consists of a front luffing boom and a backstay. Front luffing boom can be pitched or extended to meet different ship operation needs, while backstay is to balance counterweights. The length of main beam is customized according to the design requirements of the dock to ensure coverage of the entire berth. STS crane legs are at both ends of main girder, supporting the entire structure and ensuring its stability during operation. The lifting mechanism realizes the lifting of the container through a wire rope and pulley set. While electric trolley moves horizontally along main girder track, driving the precise positioning of the spreader.

Central structure of sts crane is supported by sea and land-side columns, forming a frame spanning container trucks and ships. The portal beam connects main girder and realizes the pitching action of luffing boom through the articulation system. Cabin control room is usually under the gantry, providing the operator with a good field of view, but it could also be replaced by sensors and cameras in fully automated quayside sts crane.

The lower structure includes a walking mechanism and foundation support. The crane moves along the ground track, drives the wheel set by a motor. And there are windproof devices to ensure stability under strong winds. Power supply system provides power through cable reels or sliding contact wires to ensure the continuous operation of the equipment.

The whole design takes into account both efficiency and safety. STS crane can adapt to the operating needs of super-large container ships, and is an indispensable key equipment for modern ports.

Advantages of Quay STS Crane

Efficient loading and unloading capability

• High-speed operation: lifting speed (50-90m/min) and crane walking speed (150-240m/min) ensure fast turnover.

• Large span coverage: The extension distance is more than 70m, and it can cover super-large container ships (such as 24,000TEU ships).

• Double box spreader: Advanced shore bridge supports simultaneous lifting of double 40-foot containers, increasing efficiency by more than 50%.

Structural adaptability and stability

• Pitchable/retractable front beam: folded when not working (reduce wind resistance and dock space occupation), and extend to the side of the ship during operation.

• Wind resistance design: equipped with rail clamping device, anchoring device and real-time wind speed monitoring to resist typhoons above level 12 (such as 55m/s wind speed).

• Lightweight high-strength material: The main beam adopts Q690 high-strength steel or truss structure, balancing strength and self-weight.

Intelligence and automation

• Automatic alignment system: visually identify container position through laser scanning + AI, with an error of ≤±5cm.

• Remote control/unmanned operation: Automated terminals (such as Qingdao Port and Rotterdam Port) realize remote monitoring and unmanned operations.

Main Application

Large container terminal
In the busy international container terminals, the shore bridge is used to efficiently load and unload large container ships, significantly improving port throughput and operational efficiency.

Multipurpose port
Multipurpose ports need to handle a variety of cargo types, and shore bridges can flexibly respond to containers of different sizes and weights to meet diverse operating needs.

Automated dock
In highly automated docks, quayside crane integrates advanced control systems to achieve unmanned operation or remote monitoring, improving operational accuracy and safety.

Regional small and medium-sized marinas
Regional small and medium-sized terminals use sts crane to carry out efficient container loading and unloading, optimize resource allocation, and improve the quality and efficiency of local logistics services.
