HR4500 Series V HY-RAIL® Guide Wheel Equipment

The Harsco Rail TM HR4500 Series V HY-RAIL® guide wheel attachment is used to adapt heavy-duty, chassis-cab trucks meeting Harsco Rail’s recommended vehicle specifications for highway / railway applications where a vertically-actuating front unit is desired. This unit is ideal for applications where it is necessary to minimize front unit overhand. The unit attaches to the vehicle’s front end with mounting brackets and spacer specific to the vehicle model

HR4500 Series V units are for front end position installation and may be used in conjunction with other Harsco Rail TM rear units.

HR4500 Series V units feature mounting flanges with multiple mounting holes and telescoping guide tubes with internal coil spring suspension and externally mounted double acting hydraulic cylinder for raising and lowering the unit.

With bolt-on mounting, the unit is easily adjustable for vehicle load, clearances and tracking. Air-actuated, tread-type brakes with composition shoes are standard. Optional fixed rail sweeps are available.

Available in insulated and non-insulated versions. A hydraulic power unit is also available for installation on vehicles not equipped with hydraulic systems.
