Rail Sleeper Renewers from HMA Materials handling are currently used by various railways authorities to remove condemned sleepers and simultaneously replace them with new ones. Additional flexibility is provided by a ‘wrist action’ for gripping sleepers on embankments. The sleeper gripper head can be adapted to suit a large range of timber sleepers as well as concrete sleepers. The Rail Sleeper Renewer from HMA Materials Handling is powered by an air-cooled diesel engine providing hydraulic power to all of the above motions plus track jacks, rail clamps, a centre for tracking jack and hydraulic drives and brakes.
