مقدمة المنتج

Ship-to-shore quay crane, also known as STS crane is the core lifting equipment at the front of the container terminal. The quay container crane is the key to the efficient operation of modern ports. It looks like a precise and strong giant, specializing in loading and unloading container ships. The main function is to connect the logistics transfer between vessels and terminals seamlessly. Quay container cranes could easily unload containers directly from ships to terminals, or vice versa. And then it is capable of loading containers accurately and precisely from terminals to ships to safeguard the smoothness of container transportation.

The metal structure has high strength and excellent stability, providing solid support for the whole equipment. No matter how much load it faces, it can be as stable as a mountain, guaranteeing the safe operation of the equipment. Weihua quay crane is in strict compliance with international standards such as FEM, DIN, IEC, AWS, GB, etc. This series of high standards ensures the quality and an internationally leading level.

Quay Crane Structure

Quay cranes are mainly composed of Gantry Frame, Boom/Girder, Hoisting Mechanism, Trolley Travel System, Gantry Travel System, Spreader, electrical and control system, metal support structure, and other parts.

• Gantry system: Made of high-strength steel, it supports the weight of the whole machine and moves along the track, with strong stability and wind resistance.
  Bridge (beam): It can be designed to be pitchable or telescopic, and the front beam can pitch (lifted when not in operation), which is convenient for ships to dock and leave the dock. The telescopic type is suitable for docks with limited clearance, extending during operation and retracting during non-operation.
• Lifting mechanism: It adopts a dual-speed lifting design, high speed when empty and low speed when fully loaded, equipped with an overload protection device to improve loading and unloading efficiency.
  Trolley running mechanism: Move the spreader along the bridge track, equipped with a shake reduction device to improve the positioning accuracy of the container.
• Crane running mechanism: Drive the whole machine to move along the dock track, DC motor speed regulation, adapt to frequent start and stop, and wind protection needs.
• Quay crane spreader: Intelligent telescopic design, suitable for a variety of box types, supports double-box operation, improves loading and unloading efficiency.
• Electrical and control system: PLC+ variable frequency drive, supports automatic operation, integrated with multiple safety protection functions.
• Metal support structure: High-strength tie rods and hinges optimize force, reduce motor load during pitch, and enhance stability.

المزايا

• Multifunctional container handling system: configurable single/double container spreaders, equipped with electronic anti-sway technology, can achieve accurate container loading and unloading in various operating scenarios.
• Intelligent lifting system: lifting capacity of 35-65 tons, with adaptive lifting mechanism, equipped with dynamic load optimization function, stable and efficient transfer when fully loaded and empty containers.
• Accurate positioning: integrated trolley and gantry operating mechanism, achieving millimeter-level positioning accuracy, meeting seamless shore container transfer operations.
• Advanced intelligent operation platform: adopts variable frequency multi-drive feedback technology, real-time trajectory tracking, optimizes operation efficiency, and expands service scope.

Types of quay cranes

According to different structures and application requirements, shore bridge cranes can be mainly divided into the following types and features:

1. Conventional single trolley shore bridge: Adopts a single lifting trolley structure, lifting capacity of 30-50 tons, outreach distance of 40-50 meters, economical and practical, with low maintenance costs, suitable for small and medium-sized ports.

2. Double trolley quay crane: Adopting a front and rear double trolley design, the front trolley is responsible for ship-transfer platform handling, and the rear trolley is automatically docked to the AGV system, with a theoretical efficiency of 80-100TEU/h, applicable to large-scale automated terminals.

3. Girder lifting type: The girder can be lifted and adjusted to adapt to different ship heights and reduce wind resistance during non-operation.

4. Super post panamax quay cranes: outreach ≥ 65 meters, lifting height ≥ 40 meters, rated lifting capacity of 65 tons, can meet the needs of 22 rows of ultra-large container ship operations.

5. Low profile: optimized structure reduces the height of the whole machine, applicable to terminals or inland river ports with limited headroom.

6. Fully automated bridge: integrated intelligent system scheduling, automatic positioning (GPS accuracy ±15mm), without manual operation, suitable for intelligent automated ports with high throughput.
