A crawler crane is mounted on an undercarriage with a pair of caterpillar tracks that provide stability and mobility. Their configuration – such as boom length, backmast and counterweight - can be adjusted to specific requirements. This provides additional lifting capacity. Crawler cranes can crawl with a load, allowing more flexibility in lifting. They can carry loads ranging from 60 to 3,000 tons. Mammoet has access to a large and diverse fleet of crawler cranes, which allows us to serve a variety of customers’ needs and guarantee a high level of availability.
