The gasoline powered boom lift (gas model) uses a 4-cycle, 8-horsepower Honda engine.
The engine drive shaft is directly coupled to the hydraulic pump. A 12 Volt DC storage
battery powers the engine starter circuit. An auxiliary voltage regulator/rectifier provides
up to 18 Amps charge current while the engine is running.
The battery powered boom lift (DC model) uses a 24 Volt, 39 Amp, one horsepower,
DC motor to drive the hydraulic pump. The DC motor is powered by four 6 Volt DC,
245 Amp-hour, deep charge batteries connected in series. A 40 Amp, automatic, on-
board battery charger is provided for recharging the batteries at the end of each work pe-
riod.
The boom lift is equipped with basket and ground station control panels (Figure 2-2).
The control panels include motion enable pushbuttons and proportional hydraulic valves
for controlling the direction and speed of boom lift and rotation. The gas model basket
station control panel includes an engine start pushbutton. Boom elevation and rotation
controls are operational only when the outriggers are correctly extended and the moving
boom sections are within a programmed safe operating zone.
