Abstract: A wrecker-type recovery vehicle for recovering other, disabled vehicles, and a method for doing so, which may use a CAN Bus, and which may employ wrecker controls located a distance from a side surface of the vehicle exterior. Traveler rollers may be used to facilitate longitudinal movement of a travel base assembly supporting the boom, relative to the vehicle frame.

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.

Abstract: A drum brake service tool and a method of using the same is disclosed. The tool comprises a lever having a pair of spaced, parallel arms disposed at one end thereof, the arms being adapted to receive a brake spring substantially perpendicularly therebetween. A brake-spring retaining mechanism is disposed proximate the free end of each of the arms. One of the free ends of the brake spring is passed over the brake-spring pin of one of the first or second brake shoes. The brake-spring is then engaged in between the arms of the lever. The lever is pivoted on the cam to extend the brake-spring to the point that the other free end of the spring lies proximate the brake-spring pin of the second brake shoe. The free end of the spring is then engaged with the pin of the second brake shoes. The tool may also be used to remove or install a brake roller in the brake shoes.
