On-Site Setup
A. Position the vehicle in an area free of overhead restrictions. Check capacity chart for
tasks required and position the crane in the proper place to complete the task safely.
B. Maintain a clearance of at least 10 feet (3.05 M) between any part of the crane,
loadline or load and any electrical line carrying up to 50,000 volts. One additional
foot (.30 M) 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
crane and load maintain minimum clearances required. Power lines and loadlines
deflect in wind and additional clearance 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 crane
and load to energized power lines, and warn when approaching the minimum safe
distance. Use non-conductive tag lines.
D. The crane 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 the outriggers first so the crane is level from side to side, and raise the
vehicle’s front tires clear of the ground. Level crane using the bubble levels on the
console. Then extend stabilizers so crane is level from front to rear and rear tires are
off ground. After the crane 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.
Operating out of level will drastically reduce stability.
H. Run all controls and safety devices, including the anti-two block system, through a
cycle prior to lifting loads.
I. Operate control levers and engine speed smoothly to avoid sudden starts and stops,
which could cause loads to swing.
