HR4000 Series A HY-RAIL® Guide Wheel Attachment

Harsco Rail's HR4000 Series A HY-RAIL® guide wheel attachment is used to adapt heavy-duty, chassis-cab trucks, meeting Harsco Track Technologies' recommended vehicle specifications for highway and railway applications.

The HR4000 Series A unit is for rear position installation and may be used in conjunction with other Harsco Track Technologies' front units.

The unit is lowered and raised vertically with a hydraulically-actuated "rotational" type mechanism.

The HR4000 Series A features a self-centering, side shift mechanism that enables the operator to place the vehicle "on-rail" even with the rear tires up to three (3) inches out of position.

Lever released, positive mechanical locks hold the guide wheel unit in both the highway and rail positions.

The unit bolts directly to the vehicle's frame rails and feature height-adjustable mounting. Mounting brackets are specifically designed for each approved vehicle model to make installation easier and assure mounting integrity. The unit is available in insulated and non-insulated versions. Also available are optional air-actuated, tread-type brakes with composition shoes and optional fixed rail sweeps. An electric air compressor and a hydraulic power unit are available for installation on vehicles not equipped with air brakes or hydraulic systems.

Like all HY-RAIL® guide wheel units, HR4000 Series A units are manufactured with proven Harsco Rail quality methods such as non-destructive evaluation of critical parts using x-ray and / or ultrasonic methods to assure reliable service.
