SAFETY INFORMATION

Published 5-27-2018 Control # 039-06
Use adequate cribbing under outrigger floats to distribute
weight over a greater area. Check frequently for settling.
Read and follow the following safety decal for cranes with
center front stabilizers.
Carefully follow the procedures in this Operator Manual
when extending or retracting the outriggers. Death or serious
injury could result from improper crane setup on outriggers.
The operator must select the proper
Load Chart
and Rated
Capacity Limiter (RCL) System program for the outrigger
position selected.
Before swinging the superstructure over the side when the
outriggers are retracted, check the
Load Chart
for backwards
stability.
Long cantilever booms can create a tipping condition when
in an extended and lowered position. Retract the boom
proportionally with reference to the capacity of the applicable
Load Chart
.
Check crane stability before lifting loads. Ensure the
outriggers are firmly positioned on solid surfaces. Ensure the
crane is level, brakes are set, and the load is properly rigged
and attached to the hook. Check the
Load Chart
against the
weight of the load. Lift the load slightly off the ground and
recheck the stability before proceeding with the lift.
Determine the weight of the load before you attempt the lift.
Outrigger beams and jack cylinders (plus center front
stabilizer, if equipped) must be properly extended and set to
provide precise leveling of the crane. Tires must be clear of
the ground before lifting on outriggers.
KEEP THE BOOM SHORT. Swinging loads with a long line
can create an unstable condition and possible structural
failure of the boom.
Load Charts
Load Charts
represent the absolute maximum allowable
loads, which are based on either tipping or structural
limitations of the crane under specific conditions. Knowing
the precise load radius, boom length, and boom angle
should be a part of your routine planning and operation.
Actual loads, including necessary allowances, should be
kept below the capacity shown on the applicable
Load Chart
.
Load Chart
capacities are based on freely suspended loads.
You must use the appropriate
Load Chart
when determining
the capability of the crane in the configuration required to
perform the lift.
Maximum lifting capacity is available at the shortest radius,
minimum boom length, and highest boom angle.
Do not remove the
Load Charts
from the crane.
Work Site
Prior to any operation, you must inspect the
entire
work site,
including ground conditions, where the crane will travel and
operate. Be sure that the surfaces will support a load greater
than the crane’s weight and maximum capacity.
Be aware of all conditions that could adversely effect the
stability of the crane.
WIND FORCES
There are basic principles that must be followed while
operating in windy conditions. This information has been
