2 GENERAL INTRODUCTION
The Bil-Jax 3522A Articulating Boom Lift (Figure 2-1) is a Summit
Series™ Trailer-Mounted Boom, designed and manufactured to position
personnel with their tools and equipment at overhead work locations.
The work platform load capacity is rated at 500 pounds. During all boom
operations, four extended outriggers support the unit.
The boom lift is battery powered and operated with electronic pushbutton
controls, a hydraulic power unit, a hydraulic gear motor and hydraulic
cylinders. The hydraulic power unit includes a reservoir, pump and
control valves. Three hydraulic cylinders elevate the lower boom, upper
boom and jib boom. A fourth cylinder extends a telescopic boom. A
master and slave cylinder maintain the work platform at level while
raising and lowering the boom. The hydraulic motor and mating worm
gear allow the boom to rotate 700º around a vertical axis.
