Common Uses for Crawler Cranes
Crawler cranes were made for stability and mobility around a worksite and can lift 40 to 3,500 short tons. In comparison with mobile cranes, crawler cranes are better across softer earth, but are not easy to move around because of their much heavier weight. Crawler cranes are often left at the job site because it is expensive to move it as some models must be disassembled for transportation.
Main Components for Crawler Cranes
Lattice booms and a hook are common on crawler cranes. Crawler cranes can perform a variety of work and there are many attachments to replace the hook, including draglines, clamshells, pile drivers, wrecking balls, augers, and magnets.
Manufacturers & Models
The primary factor in determining which model of crawler crane is right for the job is to the capacity of the lift and is determined by the following factors:
- • Length of crane boom needed
- • Maximum working radius
- • Total load weight including the crane hook and lifting tackle
- • Clearance for swinging crane
- • Areas where the boom may become obstructed
Before choosing a crawler crane, it is important for you to understand the state and federal OSHA requirements and the ASME B30.5 Crane standards.
