Gantry crane
Bridge Construction RTG Crane
Product Overview
The Bridge Construction RTG (Rubber Tire Gantry) Crane is a specialized heavy-duty lifting solution engineered for the demands of precast concrete factories and bridge construction sites. With an exceptionally wide lifting capacity ranging from 20 tons to 2,000 tons, this crane is designed to lift, transport, and position massive precast concrete elements like beams, segments, and blocks. Its robust structure and advanced mobility make it an indispensable piece of equipment for modern infrastructure projects, ensuring efficiency and safety in handling oversized loads.
Product Advantages
- Massive Lifting Capacity: Capable of handling loads from 20 to 2,000 tons, accommodating the heaviest precast concrete components.
- Fully Customizable: Key parameters including lifting capacity, height (5m to 80m), and span (5m to 50m) can be tailored to specific project requirements.
- Advanced Mobility: Features oil cylinder-driven steering with a wide steering angle and optional 360-degree steering for superior maneuverability on complex job sites.
- Durable and Versatile: Built with a strong gantry structure and equipped with radial engineering tires or explosion-proof solid tires for reliable performance in demanding environments.
- Comprehensive Structure: Comprises a gantry structure, girder, crane traveling system, power and electrical systems, operator cabin, and specialized lifting system with a spreader for secure handling.
Application Scenarios
- Precast Concrete Yards: Transporting and stacking finished concrete beams from the fabrication area to storage locations.
- Bridge Construction Sites: Lifting precast beams, sections, and segments from transport vehicles to their final installation positions.
- Segmental Bridge Assembly: Precisely lifting, aligning, and splicing prefabricated bridge segments during the construction process.
- Material Handling: Moving other large construction materials, such as steel reinforcement frames and formwork, within the prefabrication yard.
