Sleipner’s innovative system for transporting tracked excavators in open-pit mines and quarries is essentially a dolly system consisting of ramps with axles and large wheels. One end of the excavator’s tracks is driven onto the ramps so that the tracks are lifted from the ground. Then the excavator turns around and places the boom on the bed of a dump truck so that the other end is raised from the ground by the boom. The excavator can then be easily and quickly moved to another location, reducing wear on the excavator’s undercarriage and tracks. There are 11 models covering excavator weights from 30 to more than 550 tons. Most models incorporate different ramp sizes to fit different excavator brands and models. The newest model, E550, is the largest and can move 550-ton and larger excavators.
