Gantry crane
Mobile Rubber Tired Gantry Crane | Yard Mobility, Heavy-Duty, CE-Compliant
Product Overview
The 20–50 Ton Mobile Gantry Crane is a heavy-duty, highly flexible lifting solution designed for facilities that require high capacity without the constraints of a fixed rail system. This crane features a robust A-frame double girder structure mounted on large, durable rubber tires, giving it the freedom to travel anywhere on a firm, flat surface. It combines the strength of a heavy gantry crane with the mobility of a yard vehicle, making it an incredibly versatile asset for outdoor stockyards, large manufacturing plants, and project sites where operational flexibility is key.
Product Advantages
- Unmatched Mobility: Equipped with heavy-duty rubber tires and advanced steering options, this crane can move and maneuver freely around your yard, servicing multiple areas and navigating obstacles with ease. It is not limited to a fixed path.
- No Rail Infrastructure Costs: This system operates independently on the ground, completely eliminating the significant cost and civil works associated with installing and maintaining ground rails.
- Flexible Operational Use: Perfect for facilities with changing layouts or for project-based work. The crane can be easily relocated to different sites or different areas of a large yard as lifting requirements evolve.
- Powerful and Stable Lifting: The double-girder design provides exceptional stability for lifting heavy and off-center loads, ensuring safe and precise handling of materials up to 50 tons.
- Robust Outdoor Design: Engineered for A5 work duty and built with an IP55 protection rating and a durable all-weather paint finish, this mobile gantry crane is designed for reliable performance in rugged outdoor conditions.
Application Scenarios
- Precast Concrete and Pipe Yards: Ideal for lifting, transporting, and stacking large concrete segments, pipes, and beams across extensive storage yards with maximum flexibility.
- Large-Scale Manufacturing: Provides mobile heavy lifting capability for outdoor assembly, moving large modules between fabrication halls, and positioning heavy equipment.
- Steel Stockyards and Service Centers: Efficiently handles heavy steel plates, coils, and structural sections, allowing for dynamic organization of the yard without being tied to a fixed crane path.
- Port and Intermodal Yards: A versatile solution for moving heavy cargo, equipment, and even containers in areas not serviced by larger container handling equipment.
- Shipbuilding and Repair: Can be used to transport large vessel sections and heavy equipment around the shipyard to various points of assembly or repair.
