HR1820 Series B3 HY-RAIL® Guide Wheel Equipment

Harsco Rail's HR1820 Series B3 HY-RAIL® Guide Wheel Attachments adapt medium duty chassis-cab trucks and similar vehicles meeting HTT's recommended vehicle specifications, for railway applications requiring travel on the highway and on the rail.

These units are ideal for applications utilizing vehicles in the medium duty range, and that have a front axle width not compatible to track gauge.

Model 1820 Series B3 guide wheel equipment consists of a vertical lift type front unit and an individual wheel arm type rear unit. The front unit features coil spring suspension and the rear unit is disc-spring equipped to provide a smooth ride, enhance on-rail traction of the vehicle's drive wheels, and help maintain essential guide wheel to rail contact.

Guide wheels are raised and lowered hydraulically with power supplied from vehicle equipment systems or from an optional power pack. Double-acting hydraulic cylinders make raising and lowering of each unit easy. Positioning of the guide wheels is controlled by manually-actuated valves located at each unit.

Positive mechanical locks secured by safety pins retain the guide wheels in both the highway and rail positions.

Major Features

  • Vertical-lift front unit minimizes front end overhang for easier handling and a smoother highway ride.
  • Individual wheel arm design of rear unit increases vehicle payload capacity and simplifies mounting. This feature allows compact mounting around rear fuel tanks.
