Section 4 — Before You Operate…
All operators involved in the use and/or care of this unit
must know the location and understand the operation of
each control on the unit. Control locations are pointed out
in Component Identication. Operation of the controls is
explained in Section 6.
Capacity and Stability
A chart showing the load capacities of the particular
model is located on the turntable. This chart is used when
lifting a load without personnel in the platform. A range
diagram is also located on the chart. If the unit is specied
for platform use it will be equipped with a special rated
capacity chart (also on unit) and a boom angle indicator
visible from the platform. This chart is used when the
personnel platform is installed. The load capacity charts
found on the unit are the only charts valid for determining
the capacity of each particular unit.
The values on the load capacity charts reect vehicle
stability and structural competence. The rated working
load of the winch line may also limit the loads lifted by
the unit. The load capacity values on the chart near the
riding seat controls show the maximum loads that may
be lifted by the unit at regular intervals of load radius,
through the full range of boom elevation, extension, and
rotation, and still maintain vehicle stability. The operator
may use the capacity chart to determine whether or not
a load may be lifted.
Stability will be maintained if the values listed in the chart
are not exceeded and the outriggers are properly posi-
tioned to level the unit as described in Section 6 under
Outriggers. Also refer to other considerations listed in
Section 3 when using the capacity charts.
WARNING
Death or serious injury can result if the unit becomes
unstable. Determine the weight of the load before
lifting.
Death or serious injury can result from overloading
the unit. Do not exceed the rated capacity values.
Determine the weight of the material before moving it.
Use the placards on the unit and in the Operator’s Manual
to determine the available rated lifting capacities. Do not
exceed rated lift capacities.
WARNING
Death or serious injury can result if the unit becomes
unstable. Properly set the outriggers to level the unit
before moving the booms from the rest.
CAUTION
Injury and property damage can result from abrupt
reversals in direction, starts, or stops. Operate the
controls smoothly.
NOTICE
Refer to the platform use capacity chart for limitations
when personnel are in the platform.
Avoid side loading of the booms. Side loading can
result in damage to the structures or rotation system
and can adversely affect vehicle stability.
The unit is equipped with outriggers to help stabilize the
unit while it is in use.
Understand the stability characteristics of this unit before
using it. As delivered, this unit will meet or exceed the
requirements for stability as set forth in ASME B30.5 at
the time of manufacture.
Using the unit in an unsafe manner or overloading the
unit can cause structural failure or instability.
The stability characteristics of a vehicle vary as the boom
is rotated to different positions around the vehicle. There-
fore, any load being rotated should be kept as close to
the ground as possible. This will allow the load to settle
to the ground, rather than tip the unit over, if the vehicle
becomes unstable.
Lowering or extending the boom increases the load radius.
Use caution when lowering the boom with a load on the
winch line. The unit’s capacity and stability decrease as
the boom is lowered.
WARNING
Death or serious injury can result if the unit becomes
unstable. Park on a rm surface before operating the
unit. Set the parking brakes and extend the outriggers
as instructed under Outriggers. Take into consider-
ation pad loads on all surfaces.
It is impossible to foresee all situations and combina-
tions for set up of the unit. Establish criteria for stable
operation of the unit based on actual conditions, work
procedures, and experience. The owner and operator
bear ultimate responsibility for ensuring that the unit is
properly set up.
