Working Mode of Tyre Straddle Carrier in Prefab Yard

• For Full-Width Box Beams, U Beams, T Beams, and I Beams: The tyre straddle carrier operates with a dual-point lifting system, facilitating the lifting and transportation of whole box beams, U beams, T beams, and I beams. Alternatively, two straddle carriers can collaborate to lift and transport these larger components.
• For Segmental Beams: When dealing with segmental beams, the straddle carrier system employs a single-point lifting approach for effective lifting and transportation.

Working Mode of Tyre Crane for Overhead Line Construction

• Dual-Crane Configuration for Dual-Track Bridges: In scenarios involving dual-track bridges, the tyre crane can be equipped with two trolleys on separate sides. This arrangement allows simultaneous construction from both sides of the bridge, significantly boosting work efficiency. The double girder gantry crane structure allow it works smoothly and stably.
• Single-Crane Configuration for Single-Track Bridges: For single-track bridges, a single tyre crane is commonly utilized. The crane’s lifting mechanism incorporates a rotating hoisting system that enables adjustments in three directions. This flexibility ensures that beam segments can be positioned and aligned precisely as needed for construction.

Working Principle of Straddle Carrier For Sale

Both the tyre straddle carrier in the prefab yard and the tyre crane for overhead line construction are advanced “mechanical-electrical-hydraulic” integrated products. They operate based on the following principles:

• Hydraulic Drive: The products utilize a full hydraulic drive system for movement, allowing for smooth and precise control during operation.
• Electric Winch: The lifting mechanism employs an electric winch for raising and lowering components.

• Independent Steering: The steering system employs independent steering for each suspension wheel assembly, enhancing maneuverability and control.
• Electro-Hydraulic Steering Control: The steering system is controlled through an integrated “mechanical-electrical-hydraulic” system, optimizing steering precision and efficiency.

• Winch Trolley: The winch trolley serves as the lifting mechanism, equipped with a winch and pulley system that enables the precise vertical movement of the carrier’s spreader or lifting device. This component plays a pivotal role in safely raising and lowering cargo.
• Main Girder: The main girder forms the structural backbone of the straddle carrier, supporting the weight of the cargo and other components. Engineered for robustness and durability, the main girder provides the necessary stability and load-bearing capacity.
• Power Module: The power module encompasses the carrier’s engine, transmission, and other power-related systems. It generates the mechanical force required for the carrier’s movement, enabling both its mobility and lifting capabilities.
• Spreader: The spreader is the attachment affixed to the winch trolley that interfaces directly with the cargo. This component securely holds and lifts containers or other cargo types, ensuring their safe movement during loading and unloading operations.

• Cab: The operator’s cab is the control center of the straddle carrier. It houses the controls for steering, lifting, and other functions. The cab’s ergonomic design enhances operator comfort and provides a clear view of the surrounding environment.
• Ladder and Platform: The ladder and platform provide access to the operator’s cab and other service points on the carrier. These components ensure that operators and maintenance personnel can safely reach various areas for inspection and maintenance.
• Crane Trolley: The crane trolley facilitates horizontal movement of the spreader along the main girder. It enables precise positioning of the cargo for loading and unloading operations, ensuring optimal alignment with transport vehicles.

Each of these components plays a crucial role in the straddle carrier’s seamless operation. Their synergy combines to create a powerful and adaptable machine capable of efficiently handling a variety of cargo and enhancing productivity in logistics and maritime operations.
