What Is Container Straddle Carrier?

Container Straddle Carrier Video

Dafang Container Straddle Carrier is a heavy-duty, tire-mounted container handling solution for global container logistics. Boasting 30-80t rated capacity and 12-16m adjustable span, it features omnidirectional steering, telescopic twistlock spreaders, and dual power options (diesel-hydraulic/electric). 

What is Container Straddle Carrier's Composition?

1. Portal Frame: The core load-bearing component, spanning 12-16m to straddle containers/heavy components. Made of high-strength steel, for 30-80t load and -20℃~60℃ temperature resistance.
2. Main Beam: Connects portal legs, supporting the hoisting system and spreader. box-type design for rigidity; modular structure for easy maintenance.
3. Telescopic Spreader: Clamps and lifts containers, adjustable for 20’/30’/40’ standard sizes. Equipped with automatic twistlocks for secure locking; anti-sway technology reduces load displacement.
4. Hoisting Mechanism: Powers vertical lifting via hydraulic or electric winches. Variable-frequency control for smooth speed adjustment (8-15m/min loaded); energy-saving hybrid options available.
5. Heavy-Duty Tires: Supports the entire machine weight and ensures mobility on concrete/asphalt surfaces. 6-8 large-diameter tires with low ground pressure, wear-resistant and shock-absorbing.
6. Omnidirectional Steering Mechanism: Enables longitudinal, transverse, and diagonal travel. In-situ 360° turning for tight yard spaces; precise positioning for stacking operations.
7. Power Unit: Supplies energy for travel and hoisting. Dual options—diesel-hydraulic (for heavy-duty outdoor work) or full electric (lithium battery, Stage V emission compliance).
8. PLC Intelligent Control Cabinet: Integrates operation signals for lifting, travel, and safety monitoring. Real-time data feedback (load, height, speed); customizable for automated workflow integration.
9. Ergonomic Operator Cab: Centralizes controls for operator comfort and efficiency. Wide-view windows, adjustable seat, and digital display for intuitive operation.
10. Safety Devices: Overload Sensor, Wind Speed Anemometer, Twistlock Position Monitor, and Anti-Collision Device etc. to ensure safe and stable operation.

How Do Container Straddle Carriers Work?

A container straddle carrier operates via seamless collaboration of modular systems to handle heavy loads efficiently.

• It navigates to the target container using omnidirectional steering, with the PLC system adjusting the telescopic spreader to match container size (20’/30’/40’).
• The spreader lowers, and twistlocks automatically lock into the container’s lock holes for secure clamping. Powered by hydraulic or electric hoisting, the spreader lift the load smoothly at 8-15m/min, with overload sensors preventing excess weight.
• The heavy-duty tire system enables longitudinal/transverse/diagonal movement, even in tight spaces. Upon reaching the target area, the spreader lowers precisely, aided by wind speed monitors for stability, and places the container (up to 1-over-3 stacking).
• Finally, twistlocks unlock, the spreader resets, and the carrier moves to the next task—all controlled by intelligent PLC for safety and precision.

Dafang Container Straddle Carrier For Sale

With strong load and stacking capacity (3-4 layers typically), they are ideal for efficient turnover of bulky, standardized goods. Customers mainly use them for transferring and stacking standard containers (20ft, 40ft, 45ft) in ports, logistics parks, and container yards. They can also handle special containers (refrigerated, dangerous goods, open-top, flat-rack) and heavy loads of similar dimensions, such as steel coils, precast concrete components, large equipment modules, and bulk cargo containers.
