Crawler crane

nounStandard termBuilding

A heavy lifting crane mounted on an undercarriage with caterpillar tracks.

A mobile crane that travels on continuous tracks instead of wheels. The tracks provide a massive footprint that distributes the machine's weight, allowing it to lift extreme loads and traverse soft, muddy, or uneven site terrain without outriggers. They are assembled on site and move very slowly.

Heard on the job

The crawler crane is bogged down in the mud near the deep foundation excavation.
