Job-Site Set-Up
Thoroughly plan the lift before positioning
the vehicle. Consider the following:
1. The vehicle should be positioned in an area
free from overhead obstructions to eliminate the
need for repositioning.
2. Position the vehicle so that it is impossible for
any portion of the equipment to come within the
minimum required safe distance of any power
line. Maintain a clearance of at least 10 feet
between any part of the crane, load line, or load,
and any electrical line or apparatus carrying up to
50,000 volts. One foot additional clearance is
required for every additional 30,000 volts or less.
Remember to allow for winds that cause power
lines to sway. It is recommended that a signal
person be used when the vehicle is set-up near
power lines.
3. The vehicle should also be positioned on a firm
and level surface that will provide adequate
support for the outrigger loading. Use extreme
caution when setting up near overhanging banks
or excavations.
4. The parking break must be set on the vehicle
and the drive axle disengaged before performing
a crane operation.
5. The outriggers must be extended to stabilize
the truck before beginning operation.
