INTRODUCTION

The container spreader is a specialized attachment used on container cranes, straddle carriers, and reach stackers for handling intermodal containers. It features a telescopic frame that adjusts to 20ft, 40ft, and 45ft container lengths, with twistlock mechanisms at each corner to lock onto container corner castings. Lifting capacity typically ranges from 30t to 50t, with optional features such as anti‑sway, floating flippers, and single‑spreader for twin‑lift. This spreader enables safe, efficient stacking and transferring of containers in ports, rail yards, and depots.

APPLICATION SCENARIO

[1] Container terminals – Lifting and stacking containers between ship and yard.

[2] Intermodal rail yards – Transferring containers between railcars and trucks.

[3] Inland container depots – Stacking empty or laden containers for storage.

[4] Port gate areas – Handling container inspection and weighing.

[5] Medium‑sized port cranes – Fixed or manually adjustable spreaders for smaller operations.

ADVANTAGES

1. The main frame of the container spreader has high strength, good rigidity, and light self weight. The main beam of the lifting appliance is made of I-beam steel, and strengthened at the four key lifting points and cantilevers, thereby enhancing the bearing capacity and rigidity of the lifting appliance.

2. The rotary lock adopts a dual positioning device, which prevents the lifting tool from rotating when lifting the container, enhancing safety performance.

3. The horizontal transmission rod of the lifting appliance adopts a four link mechanism, which makes the rotation of the rotary lock smoother and more accurate, thereby further improving the safety of loading and unloading operations.

4. The four corners of the lifting appliance are designed with rounded corners, which will not damage the container during operation.

5. The lifting appliance is equipped with an opening and locking indicator board, which allows the driver to determine the opening and locking status based on the opening and locking indicator board.

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.
