Abstract
A recovery vehicle for recovering other, disabled vehicles, and a method for doing so. A vehicle frame extends along a longitudinal axis, and supports a travel base assembly carrying a boom. The travel base assembly can move along the longitudinal axis of the frame. Two or more traveler rollers may be located between the vehicle frame and the travel base assembly, for supporting the travel base assembly and facilitating longitudinal movement of the travel base assembly relative to the vehicle frame. The traveler rollers may include a plurality of rollers movable about a load-bearing member. Using the invention, a load may be lifted by the boom and moved between positions located at the rear and to the side of the recovery vehicle, without the need to first reposition the boom using boom lift or telescoping cylinders.

A recovery vehicle comprising a wrecker for recovering other, disabled vehicles, comprising:
- a vehicle frame extending along a longitudinal axis, the vehicle frame supporting a travel base assembly carrying a boom with a lift cylinder, wherein the boom can extend or retract, the travel base assembly is capable of moving along the longitudinal axis of the frame, and the travel base assembly supports a rotating member allowing the boom to be rotated about a vertical axis substantially perpendicular to the longitudinal axis of the frame, wherein the movements of the travel base assembly and the boom are used in recovering disabled vehicles;
- two or more traveler rollers located between the vehicle frame and the travel base assembly for reducing frictional loads created during relative movement between the travel base assembly and the vehicle frame, the traveler rollers supporting the travel base assembly and facilitating longitudinal movement of the travel base assembly relative to the vehicle frame, and each of the traveler rollers comprising a plurality of rollers linked by a chain assembly and movable about a load-bearing member and along the vehicle frame;
- and
- wherein, using the boom, a disabled vehicle may be lifted and moved.
