Abstract
A boom truck is provided which has optimum operating and transport positions. In the operating position an operator's cab is mounted substantially centrally of the chassis of the boom truck, with the boom above the cab and pivotally mounted to the rear of the cab (over the rear axle) for rotation about a first horizontal axis to provide a lifting force when the boom is pivoted by a hydraulic cylinder or similar linear actuators. In transforming the boom truck to an ease of transport position, the cab is slid on rails to one side of the chassis (preferably in the direction substantially parallel to the axles of the chassis), the support for mounting the pivot for the boom is itself pivoted about a second substantially horizontal axis so that the boom lowers, and ultimately the boom moves to a position next to the cab, with at least part of the boom, and perhaps substantially all of the boom, below the top of the cab.
