Hilman Load Rollers/Skates: Raise & Roll Rig

Hilman Rollers provided an alternative lift & roll system for a rig. The cantilever beams are supported by six rollers, each weighing 1133 tonnes. Each roller is supported by six hydraulic cylinders nested in a sub-frame. The hydraulics ensures that each roller is under full contact during the skidding mode. When retracted, the rig does not contact the rollers. No more freeze-ups! No more beam tear-ups! No more huge pushing cylinders!
