SET-UP
4
1.
All outriggers and stabilizers are extended with positive
contact on firm, level surface, the tires are free of the
ground and the machines level within 1
°
.
2.
The proper amount of counterweight has been installed,
if required.
3.
The unit is mounted in accordance with factory
instructions on a vehicle with proper specifications.
4.
The weight of load handling devices is considered as a
part of the load being lifted.
5.
The correct loadline reevings used for the load to be
lifted.
6.
Adverse environmental conditions such as wind are not
present.
7.
The operator controls the loads smoothly.
8.
Tires are inflated to the proper pressure.
9.
The load to be handled does not exceed the maximum
capacity at the boom length and loaded radius.
10.
The loads are lifted in the proper area around the truck.
A stability test should have been performed on this crane
and can be repeated by referring to the Installation Section of
the Service Manual.
All capacities are given in direct relationship to the boom
length and loaded radius at which the loads being handled.
•
All radii are measured from the centerline of rotation to
the loadline with the load suspended.
•
All variances of loads and radii of operation are shown
on the load chart mounted on the main frame.
•
Boom angle should be used as reference only to aid in
determining radius.
•
The correct loaded radius must be measured and not
exceeded during any point of the lifting operation.
•
The placards located at the operators platform for the
purpose of informing the operator when a load can or
cannot be handled.
•
Load ratings cannot be interpolated between load points
shown on the chart in the boom areas.
•
When boom length or radius or both are between points
listed on load chart, the smallest load shown at either the
next larger radius or boom length shall be used.
•
Capacities of the extension cannot be interpolated
between angles nor at reduced lengths because the
strength of the extension and its attachment point to the
boom does not increase when the boom is shortened.
NOTE:
Rated loads shown on the load chart pertain to this
machine as originally manufactured and equipped.
Modifications to the machine or use of equipment
that is not factory specified or approved can be
hazardous. Refer to capacity deduction chart for
weights which must be deducted from rated loads
when accessories are attached to boom or
loadline.
Set-Up
1.
Inspect vehicle and crane including crane operation
prior to use each day.
2.
Load ratings shown on the chart are maximum allowable
loads with the crane mounted on a factory approved
truck and all outriggers set on a firm level surface so the
crane is level. This crane is not rated for use without
outriggers.
3.
Depending on the nature of the supporting surface,
structural supports under the outrigger floats may be
necessary to spread the load to a larger bearing surface.
4.
Always level the crane with the level indicator located at
the operator stations located on either side of the crane
frame.
Operation
1.
Operation of this equipment in excess of maximum load
rating and disregard of instructions is hazardous. Always
refer to the load chart for load and area limits before
operating the crane. Rated loads at rated radius shall
not be exceeded. Over loading this crane may cause
structural collapse or instability. Do not rely on the HCA
system or the extension load limiting device to weigh the
load and control limiting boom angle and radius. Use
these system as a backup to safe operation.
2.
Use the angle indicator as a reference only. When lifting
maximum loads, measure radius.
3.
Rated loads do not exceed 85% of the tipping load as
determined by SAE Crane Stability Test Code J765a
when mounted on a factory recommended truck
NOTE:
For New York City approved units, rated load do
not exceed 75% of the tipping load as determined
by SAE Crane Stability Test Code J765a when
mounted on a factory recommended truck.
4.
Structural limited ratings on the load chart are shaded.
Stability limited loads are not shaded. Machine will not
always tip before structural damage occurs.
5.
Rated loads include the weight of the hook block, slings,
other lifting devices and boom accessories. Their
weights must be subtracted from the listed rated load to
determine the net load that can be lifted.
