Truck Mounted | GSK55

Summary

The GSK55 combines the lift ability of Grove all-terrain cranes with the flexibility and mobility of a standard on-road truck. It merges the upperworks from Grove's GMK3055 all-terrain crane with a specially-designed truck chassis that acts as a trailer. The customer can use the tractor of their choice to haul the crane to jobsites.

Features
