Abstract
This invention relates to a truck mounted forklift comprising a U-shaped chassis having a pair of side bars bridged by a rear crossbar. There is provided a driver's station, a motive power unit and a lifting mechanism on the chassis. There is further provided a skid steer drive mechanism comprising two driven front wheels and a dolly rear wheel. The dolly rear wheel is rotatably mounted about a vertical axis offset from a central axis of the dolly rear wheel, and there is a releasable locking mechanism to secure the dolly rear wheel in a fixed orientation about the vertical axis. The releasable locking mechanism comprises a hydraulically operated locking pin on the chassis and a locking pin receiver on the dolly rear wheel. The locking pin is operated by way of a locking pin actuator on a driver's console, and there is a locking pin indicator on the console to warn the operator of the locking pin configuration.
