2. General description
This device, winch is mounted on a 5 ton, long wheelbase chassis, consists of a lower and upper boom with working platform which is mounted on a turntable. The turntable is mounted directly on the vehicle chassis. Hydraulically operated spring lock-out jacks lock the superstructure firmly to the chassis. Four manually operated stabilizer jacks are also provided.
The machine is operated hydraulically, power being provided by an auxiliary engine driving a hydraulic pump.
All movements of the platform are controlled from the platform itself by means of pedals for raising or lowering and a knee operated rotation control leaving the operators hands free for his work. Duplicate controls are provided on the turntable.
The machine provides a range of movement giving the operator a maximum working height of
approximately 40 ft. and a maximum working radius of approximately 25 ft. The
turn table can rotate continuously in either direction. A number of safety devices are built into the machine covering failure of motor or
together with a cut-out stop should the platform descend on a solid obstruction. This model is now obsolescent. For details of the current model see N 3014.
