Crawler Cranes

TNT Crane & Rigging offers crawler cranes with lifting capacities ranging from 80 tons to 750 tons, providing solutions for heavy-duty lifting operations across diverse project requirements. Our crawler crane fleet includes various configurations with lattice boom systems that can be customized to match your specific lifting needs, whether you’re installing bridge components, handling industrial equipment, or managing large-scale infrastructure projects. The maximum capacity you’ll need depends on your load weight, required reach, and site conditions, which our experienced team can help determine during the planning phase.

Crawler crane assembly typically takes between 4 to 8 hours for smaller models and 1 to 3 days for larger lattice boom crawler cranes, depending on the crane size, boom configuration, and site conditions. Assembly time includes positioning the crawler tracks, installing boom sections, adding counterweights, and completing all safety checks before operation begins. TNT Crane & Rigging’s experienced crews follow OSHA-compliant assembly procedures to ensure safe and efficient setup, and some modern crawler cranes feature self-assembly capabilities that can reduce setup time to under one hour for the basic machine.

Yes, crawler cranes typically require crane mats or ground preparation to ensure adequate ground bearing capacity and prevent settlement during lifting operations. While crawler cranes exert significantly lower ground pressure than wheeled cranes, typically ranging from 1.0 to 3.0 pounds per square inch due to their tracked undercarriage, proper ground preparation remains essential for safety and stability. TNT Crane & Rigging’s lift planning team conducts thorough site assessments to determine if timber mats, steel mats, or ground improvement measures are needed based on soil conditions, crane configuration, and anticipated loads.

You should choose a crawler crane over a mobile crane when your project involves heavy lifting on soft or uneven terrain, requires extended on-site operation in one location, or demands exceptional stability for large-scale lifts. Crawler cranes excel in applications where superior ground bearing capacity and the ability to move with a load are critical advantages, such as bridge construction, industrial plant installations, and infrastructure projects on challenging surfaces. TNT Crane & Rigging recommends crawler cranes for long-term projects where initial setup time is offset by their unmatched lifting capacity and stability, while mobile cranes better suit projects requiring frequent relocation and rapid deployment.

Crawler cranes are transported to job sites by disassembling them into major components, including the main body, boom sections, counterweights, and crawler tracks, which are then loaded onto multiple lowboy or multi-axle trailers for highway transport. A typical 100-ton crawler crane requires approximately 4 trailer loads, while larger models like an 1,300-ton capacity crawler may need 17 or more loads depending on configuration. TNT Crane & Rigging manages all aspects of crawler crane transportation, including securing necessary oversize and overweight permits, coordinating escort vehicles, conducting route surveys, and arranging for qualified crews to reassemble the crane at your project site.

The required ground bearing capacity for crawler cranes varies significantly based on crane size, configuration, and lifting conditions, but typically ranges from 1,000 to 4,000 pounds per square foot for most soil types when proper crane mats are used. Crawler cranes distribute their weight more effectively than wheeled cranes due to their tracked undercarriage, exerting ground pressure between 1.0 and 3.0 pounds per square inch under normal conditions. TNT Crane & Rigging’s engineering team calculates specific ground bearing requirements for each lift by considering the crane’s operating weight, load characteristics, boom configuration, and soil conditions, then specifies appropriate crane mats or ground improvement methods to ensure safe operations.

Yes, crawler cranes are specifically designed to operate effectively in muddy or soft terrain conditions where wheeled cranes would be impractical or unsafe, thanks to their tracked undercarriage that distributes weight over a larger surface area. The wide track base provides superior flotation on soft ground, including mud, sand, and saturated soils, making crawler cranes the preferred choice for construction sites with challenging ground conditions. TNT Crane & Rigging enhances crawler crane performance in soft terrain by utilizing appropriate crane mats, conducting geotechnical assessments when necessary, and selecting crane configurations that optimize ground bearing pressure for your specific site conditions.
