99903514: TELESCOPIC CRANE: 1-4 SECTION 1: OPERATION
1-3-2: WORK STATION POSITIONING
Park the working unit on firm, level and dry
pavement or ground close to the job. Avoid
overhead obstructions.
Use wheel chocks when parking unit on a slope.
If parking on a curbed roadway, turn the front
wheels toward curb when parked with the truck
downgrade, and away from curb with rear of
truck downgrade. At the worksite, park the
vehicle with the grade. When cross-grade
parking is necessary, restrict the load to com-
pensate for the increased tipping risk.
1-3-3: OUTRIGGERS
WARNING
OUTRIGGERS CAN PINCH, STRIKE, OR
CRUSH PEOPLE OR OBJECTS!
MAKE SURE THERE ARE NO OBSTRUC-
TIONS BEFORE OPERATING
OUTRIGGERS.
Although the outriggers are critical to safe and
stable operation, they can be hazardous due to
their close proximity to the operator and other
personnel. They are the only component of the
crane which normally contacts the ground.
Your unit may have hydraulic outriggers, manual
outriggers, or a combination of both.
Figure A-4: Outrigger Operation
Before setting up the outriggers,park the carrier
vehicle over a firm and level surface for ad-
equate outrigger support. If outriggers appear to
bury themselves in a less than firm surface,
move the vehicle or improve the surface using
plates or blocks under the outriggers. DO NOT
perform a lift until a the location is suitable. DO
NOT position the outriggers near sharp drop-
offs or areas of uncertain firmness.
Extend the outrigger arms fully. If hydraulic, turn
on the engine and engage the PTO. The
outrigger hydraulic valves are located inside the
crane control cabinet. If manual, release the pin
which locks the outriggers in place and fully
extend them until they lock into position.
Lower the outrigger legs until full ground contact
and solid stability is achieved.
Before a lift is made, be certain that the parking
brake is set and the drive axle is disengaged.
Use the power down outrigger function to level
the vehicle side-to-side. Use a signal person if
the outriggers are not in view from the
operator’s station when extending or lowering
the outriggers.
WARNING!
OUTRIGGERS CAN PINCH, STRIKE,
OR CRUSH OBJECTS OR PEOPLE.
MAKE SURE THERE ARE NO
OBSTRUCTIONS IN OR NEAR
THE OUTRIGGER PATH.
1. EXTEND OUTRIGGER ARMS TO
THEIR FULL HORIZONTAL
OPERATING LIMIT.
2. EXTEND OUTRIGGER LEGS
UNTIL FULL CONTACT WITH THE
GROUND AND SOLID STABILITY IS
ACHIEVED AND THE VEHICLE IS
APPROXIMATELY LEVELED, SIDE-TO
SIDE.
