ABSTRACT:
A self-propelled pavement marking tape applicator. A slip-clutch assembly allows the operator to accurately control power transferred from the engine to the drive wheel(s) of the marking tape applicator. One-way clutch bearings provide differential action to the drive wheels when negotiating turns by allowing the wheel on the outside of the turning radius to rotate at a faster rate than the wheel on the inside of the turn. The differential action provided by the one-way clutch bearings also prevents the wheels from dragging on the pavement surface and permit the operator to manually push the marking tape applicator faster than it is being driven by the engine.
