INTRODUCTION

What is this?

The quay crane is a large lifting device specifically designed for ship loading and unloading operations at port terminals. Through the lifting and lowering of the spreader, the back-and-forth movement of the trolley, and the luffing of the boom, combined with crane traveling along dock rails, it achieves fast loading and unloading of container ships. If you are managing a seaport terminal, dedicated container terminal, or multipurpose terminal, and need a ship-to-shore handling device with long outreach, high lifting height, and fast operating efficiency, this product is designed for you.

Why choose a quay crane over a standard gantry crane?

Compared to standard gantry cranes, the quay crane offers five core advantages:

First, long outreach – the boom can extend beyond the dock front, with outreach from 35 meters to 70 meters, covering the holds of large container ships.

Second, high lifting height – lifting height above rail can reach 30 meters to over 50 meters, accommodating the loading/unloading requirements of ultra-large container ships (200,000 DWT and above).

Third, fast operating efficiency – trolley traveling speed up to 200-240 m/min, hoisting speed up to 90-120 m/min, single-unit operational efficiency reaching 30-45 containers per hour.

Fourth, boom luffing function – the boom can luff up and down, raised during non-operation to allow vessel passage, and lowered during storms to reduce wind resistance.

Fifth, comprehensive intelligent configuration – standard anti-sway system, automatic spreader positioning, vessel motion following, truck guidance, and other intelligent functions.

Enhance port ship handling capacity with more professional quay cranes.

What can we do for you?

We understand that every port has different vessel types, different berth conditions, and different operational efficiency requirements. Therefore, we offer flexible customization options: lifting capacity from 30 tons to 80 tons; outreach from 35 meters to 70 meters; lifting height from 30 meters to 55 meters; boom luffing angle customized according to dock clearance; control options of cabin or remote radio combined with cabin. Whether your port is a small and medium-sized feeder port or a large hub port, we can match the most suitable outreach and lifting height.

Unsure? Don't know?

Not sure what outreach is needed to cover your largest vessel type? Not sure what lifting height is needed to handle your largest vessel? No problem. Just tell us: your largest vessel beam width and TEU capacity, your dock front water depth, your berth length, and your target operational efficiency (containers per hour).

Six core advantages

Full Scenario Coverage

Nucleon covers over 20 product categories including ladle cranes, multi-purpose cranes, intelligent cranes, overhead/portal cranes, RTG, RMG, deck cranes, portal cranes, girder launchers, yacht cranes, KBK, and jib cranes. From steel smelting to port handling, bridge construction to ship equipment, Nucleon provides one-stop lifting solutions. Whether standard models or extreme-condition customizations, Nucleon possesses mature technical expertise and proven track records, saving customers from dealing with multiple suppliers.

Military-Grade Quality Standards

We use high-strength steel from Baosteel/Ansteel for key structural components, with 100% NDT inspection and one-clamp CNC gantry machining. Every machine undergoes 120% dynamic load and 125% static load tests before delivery, with continuous operation verification under extreme conditions. Even in 24/7 continuous casting plants, -40°C arctic ports, or high-temperature humid ship cabins, our cranes maintain millimeter-level precision and zero-drift stability—quality that stands the test of time.

Extended Longevity & Low Maintenance Cost

Our main girders are FEA-optimized and double-submerged arc welded, with a design life of ≥30 years. Key bearings are lifetime lubrication-free, and hardened travel wheels extend wear cycles by 3 times. Core components feature modular quick-change interfaces with spare parts commonality exceeding 80%. Annual maintenance costs are reduced by 40%~60%, saving millions in lifecycle operating expenses — truly "invest once, benefit long-term."

Energy Efficiency Leader

Our entire series comes standard with IE5 permanent magnet synchronous motors + energy feedback VFD drives, achieving 25%~35% comprehensive energy savings. Single-motor operation under light loads and adaptive speed control reduce electrical waste by over 30%. High-strength steel lightweight design cuts deadweight by 15%~20%, lowering workshop load requirements. A single ladle crane station saves over RMB 150,000 in electricity costs annually, helping customers achieve green and low-carbon production.

Ultimate Safety Redundancy Design

Our hoisting mechanism comes standard with dual brakes + mechanical overspeed switch + triple limit switches, featuring multiple redundant interlocks to prevent load dropping and over-traveling. Large products use box girder torsion-resistant structures, remaining stable even in level 8 gusty winds. Optional intelligent safety monitoring systems detect anomalies in load, skew, wind speed, etc., with automatic alarms and shutdowns. Overall safety redundancy coefficient > 2.0, maintaining zero crane safety incidents for many consecutive years.

Deep Customization & Full Lifecycle Service

We provide complete front-end support from site survey and mechanical simulation to civil review, delivering custom drawings within 2 weeks, with non-standard lead times only 5~7 days longer than standard products. We establish lifelong digital dossiers for customers, warning of end-of-life components 3 months in advance. Our full lifecycle services cover installation training, regular inspections, and remote O&M. With customer repeat purchase rates exceeding 85% for five consecutive years, we are a trustworthy long-term partner.
