RAS Chock/Roof Support Trailer

The SH150 roof support trailer turns your LHD into a high-speed shield hauler capable of carrying 50 tonnes (55.12 tons) and shields up to 2 m (6.56 ft) wide. The 55 000 kg (121,254 lb) RAS Chock/Roof Support Trailer is just one of the wide range of attachments available. The trailer is connected by a 5th Wheel Adapter unit to the towing vehicle. The trailer has a hydraulic powered winch for loading the Chock/Roof Support into the trailer body. The floor of the trailer is tapered allowing easy access into the trailer body by the support. Steel wear strips are welded in place for the support to slide over, reducing frictional resistance. Hydraulic powered cylinders acting on a slide plate raise and lower the trailer body to the floor. Hydraulic cylinders are incorporated in the chock/roof support positional stops and act as eject cylinders in the unloading sequence.


Optional Power Assist Drive

The hydraulic assist drive system fitted to the trailer is considered as an additional power assist unit for the trailer in areas of inconsistent floor and roadway conditions and is designed for intermittent use and not as a full time constant additional power drive. The hydraulic wheel motors are driven by the towing vehicle’s hydraulic system through the power take off (PTO) connection.
