Aerial Device Setup EEC-0072
V1.5
Aerial Device Setup
A. Position the vehicle in an area free of overhead restrictions. Check capacity chart for
tasks required and position the aerial device in the proper place to complete the task
safely.
B. Maintain a clearance of at least 10 feet (3.05M) between any part of the aerial
device, load line or load and any electrical line carrying up to 50,000 volts. One
additional foot (.30M) clearance is required for every additional 30,000 volts or less.
Set ground markers in place to be used as a reference to assist in making sure the
aerial device and load maintain minimum clearances required. Power lines and load
lines deflect in wind and additional must be provided. If the electrical line voltage is
unknown, contact the utility and obtain the voltage prior to operation. All overhead
wires must be considered energized until the electrical utility representative verifies
that they are not and the wires are visibly grounded.
C. A qualified signal person shall be assigned to monitor the distance from the aerial
device and load to energized power lines, and warn when approaching the minimum
safe distance. Use non-conductive tag lines when using boom or jib winch.
D. The aerial device must be set up on a firm, level surface with adequate support for
outrigger/stabilizer loads. Thin concrete, hot asphalt and partially frozen ground may
not support outrigger loads. Use cribbing to assist in distributing loads.
E. Always set the park brake and disengage the transmission.
F. Use a signal person to set the outriggers safely if not visible and avoid a crushing
hazard.
G. Extend outriggers first so the aerial device is level from side to side and raise the
vehicle until the suspension is unloaded. Level the aerial device using the bubble
levels. Then extend stabilizers so aerial device is level from front to rear and the
suspension is unloaded. After the aerial device is level side-to-side and front-to-
back, extend the front stabilizer (if equipped with option) until firm contact is made
with the ground. Equipment must be within 0.56° of level before operating. A portion
of the air bubble must be within the center circle. Operating out of level will
drastically reduce stability.
