How are crawler cranes transported?

Aug 20,2024

Crawler cranes are complex to transport due to their large size and weight. The following details typical ways to transport crawler cranes:

1. Disassembly

  • For ease of transport, the crawler crane is often disassembled into smaller components. Key parts to disassemble include the boom, counterweight, crawler tracks, and main mast. Disassembly is necessary to fit the crane parts within transport constraints and to simplify the loading process.

2. Loading

  • Flatbed Trucks: Smaller components, such as the crawler crane’s counterweight and smaller sections of the boom, are loaded onto flatbed trucks or specialized lowbed trailers.
  • Heavy Duty Trailers: Larger components, such as the main mast and base, may require heavy duty trailers or retractable lowbed trailers designed for oversized loads. These trailers are equipped with hydraulic systems to handle the weight and ensure stability.

3. Transport

  • Route Survey: Prior to transport, a detailed survey of the route is conducted to ensure that the roads, bridges, and infrastructure are capable of handling the heavy loads. This may involve coordinating with local authorities to obtain permits and planning any road closures or detours.
  • Escort Vehicles: Due to their large size, transport often requires escort vehicles to ensure safety and manage traffic. These vehicles help guide the crane components and may be necessary for navigating narrow roads or intersections.
  • Transportation Process: Crawler crane parts are carefully secured and handled during transport to prevent damage. This may involve the use of crawler cranes or other heavy equipment to load and unload parts.

4. Unloading

  • Onsite Assembly: Upon arrival at the destination, the crane components are unloaded and reassembled on site. This process is typically managed by an experienced team of technicians and crane operators.
  • Testing and Calibration: After reassembly, the crawler crane is tested to ensure that all components are properly installed and calibrated before being put into operation.

5. Final Setup

  • Crawler track: The crane tracks are reattached and adjusted to ensure proper alignment and functionality. 
  • The boom and counterweight are reattached and adjusted according to the manufacturer's specifications and the crane's operating requirements.

6. Other Considerations

  • Permits and Regulations: Transporting large crane components often requires special permits and compliance with local regulations. This may involve coordination with the transportation department and compliance with weight and size restrictions.
  • Weather Conditions: Weather conditions can affect shipping logistics. Inclement weather or high winds may cause delays or require additional safety measures.
  • Coordination and safety: Effective coordination between the various teams (logistics, crane operators, transport companies) is essential to ensure a smooth and safe transport process.

By carefully managing these steps, safe and efficient transport of crawler cranes can be achieved, ensuring they are ready to be assembled and used at the new location.
