Rated Capacity Chart
The rated capacity chart, located on dashboard, indicates maximum load
capacities for handlers equipped with GRADALL-furnished carriage/fork
combination. These capacities apply to standard carriage/fork combinations
except as stated on the capacity chart.
Figure 12-3
Elevation:
Numbers at left side of sample chart represent elevation to top of horizontal
fork as measured from level ground (in feet). Elevation relates to dimension
“A” shown on serial number plate, inside cab, front right side.
Boom Extension
Numbers across bottom of sample chart and numbers parallel to boom represent
boom reach as measured from front of front tires to extended position.
Number decals on boom relate directly to boom extension. The largest number
which can be read from operator’s seat indicates total boom extension and
must be matched with boom angle to determine load capacity.
Boom extension relates to dimension “D” shown on serial number plate.
Boom Angle
Numbers shown at ends of angled lines represent angle of boom to horizontal
as measured from horizontal. Maximum angles are -4° below horizontal with
boom fully lowered to 71° above horizontal with boom fully raised.
A boom angle indicator is located on left side of boom-section 1 to show boom
angle. Be sure machine is level from front to rear or indicator will provide
incorrect reading.
Load Center
Loads shown on rated capacity chart are based on the load center being two
feet (610mm) above the horizontal surface and two feet (610mm) forward of
the vertical surface of the forks.
The load center of a load is the center of gravity of the load. For regularly-
shaped loads of the same material, such as a pallet of blocks, the center of
gravity can be located by measuring the load to find its center. For irregular
loads, or loads of dissimilar materials, keep the heaviest part of the load as
close to the heel of the forks as possible.
In all cases, the load center must be centered between the forks.
Load Limits
Some capacities shown on the rated capacity chart are based on machine
stability and some are based on hydraulic lift capacity. The “common sense ”
or “feel” an experienced operator might apply in regard to “tipping loads”
DOES NOT APPLY to hydraulic load limits. Exceeding load limits can cause
damage, or, in some cases, cause the machine to tip over.
12.1
WARNING !
All loads shown on rated capacity
chart are based on machine being
on firm, level ground; the forks
being positioned evenly on
carriage; the load being centered
on forks; proper size tires being
properly inflated; and the handler
being in good operating condition.

USE CAPACITY CHART FOR SPECIFIC ATTACHMENT ON MACHINE.
FOR OTHER ATTACHMENTS CONSULT A GRADALL DEALER
FOR LOAD RATINGS NOT LISTED.
USE LARGEST NUMBER VISIBLE FROM THE CAB TO
DETERMINE BOOM EXTENSION.
MATCH WITH BOOM ANGLE TO DETERMINE ALLOWABLE LOAD.
FIGURES SHOWN ARE STACKING CAPACITY TRUCK LEVEL.
RATED LIFTING CAPACITIES SHOWN ARE WITH MACHINE ON A FIRM,
LEVEL SURFACE WITH UNDAMAGED, PROPERLY INFLATED, HYDROFILLED
(CALCIUM CHLORIDE AND WATER) TIRES.
MACHINE SPECIFICATIONS AND STABILITY ARE BASED ON RATED LIFT
CAPACITIES AT SPECIFIC BOOM ANGLES AND BOOM LENGTHS.
IF SPECIFICATIONS ARE CRITICAL, THE PROPOSED APPLICATION
SHOULD BE DISCUSSED WITH YOUR DEALER.
DO NOT EXCEED RATED LIFT CAPACITY LOADS, AS UNSTABLE AND
DANGEROUS MACHINE CONDITIONS WILL RESULT.
DO NOT TIP THE MACHINE FORWARD TO DETERMINE ALLOWABLE LOAD.
CERTAIN CARRIAGE/FORK COMBINATIONS MAY CAUSE HANDLER TO TIP
WITHOUT LOAD WHEN EXTENDED INTO "NO OPERATION" ZONE AS NOTED
ON CAPACITY CHART.
CAPACITY LIMITS FOR THIS UNIT ARE BASED IN ACCORDANCE WITH
STANDARDS LISTED ON SERIAL NUMBER PLATE.
LEVEL GRADALL HANDLER BEFORE LIFTING ABOVE 4 FT.
