99903514: TELESCOPIC CRANE: 1-3 SECTION 1: OPERATION
For maximum safety during work near
powerlines, adhere to the following guidelines:
During windy conditions, allow additional
clearance.
Do not rely on cage-type boom guards, insulat-
ing links, or proximity warning devices for safety.
Adhere to the required distances listed in Figure
A-2.
Contact the utility company before beginning
work near powerlines.
Always assume overhead lines to be ener-
gized.
Avoid transporting a crane over uneven terrain.
When using rope to steady a load or restrain
spinning of the load, be aware that rope will also
conduct electricity, especially if wet or damp.
Reduce operating speed when in close proxim-
ity to powerlines in order to allow the operator
more reaction time.
NORMAL VOLTAGE MINIMUM REQUIRED
kV (Phase to Phase) CLEARANCE Feet (meters)
OPERATION NEAR From 0 to 50 10 ( 3.05)

LOWERED. From 750 to 1000 20 ( 8.10)
Figure A-2: Required Clearance of Cranes from Electrical Transmission Lines
IF ELECTRICAL CONTACT OCCURS:
1. Shut off all power.
2. Break contact of any person in contact with a
live conductor by using rubber hose, dry rope, or
dry wood. DO NOT attempt this unless you are
certain that all power is off.
3. Call 911 or the local emergency service.
4. Administer first aid.
5. Avoid the area around the crane, as high
voltage travelling through a crane will charge the
ground.
ELECTRICAL CONTACT FOLLOW-UP
1. Inspect and repair any equipment affected by
electrical contact.
2. Replace any wire rope which has had high
voltage contact.
