ABSTRACT:
A load handling vehicle is described, having a chassis provided with wheels, an engine, and a control cab, and a telescopically extensible boom mounted pivotally on supports extending up from the rear of the chassis and a load handling carriage on the free end of the boom. The boom and carriage are hydraulically operated. Hydraulic lines to rams for extending the boom and for operating the lifting carriage are provided by a set of flexible pipes rigidly secured to the trailing end of an outermost section of the boom, and a roller is mounted on the trailing end of an intermediate section of the boom. A shrouded probe supporting the pipes within the boom extends from the innermost boom section into the other sections of the boom, locating the pipes around the roller.
