35 a-capacity limitation.
•
S. Capacities are applicable only with machine on a firm level surface.
6. On rubber lifting with jib not permitted.
7. For pick and carry operation, boom must be centered over front of machine and mechanical swing lock
engaged. When handling loads in the structural range with capacities close to maximum ratings, travel
shOUld be reduced to creep speed and load restrained from swinging.
8. Axle lock-outs must be functioning before lifting on rubber. (Check automatic lockout system for proper
functioning: Refer to "Operation and Maintenance Manual" for description of a proper functioning axle
lockout systeml.
9. All lifting depends on proper tire inflation, capacitY' and condition. Capacities must be reduced for lower
tire inflation pressures. See lifting capacity chart for tire used. Damaged tires are hazardous to safe
operation of crane.
10. Lifting loads at close radii directly over the operator's compartment is not recommended.

LIFTING CAPACITY NOTES
;~
GENERAL:
1. Rated loads as shown on lift chart pertain to this machine as originally manufactured
and equipped. Modificallons to the machine or use of optional equipment other than
that specified can result in a reduction of capacity.
2. Construction equipment can be hazardous if improperly operated or ntaintained.
Operation and maintenance of this machine shalt be in compliance with the
information in the operator's, parts. and safety manuals supplied with this machine.
If these manuals are missing, order replacements from the manufacturer through the
distributor.
3. The operator and other personnel associated with this machine Shall fully acquaint
themselves with the latest applicable American National Standards Institute (ANSII
Safety Standards for cranes.
"
SETUP:
1. The machine shall be leveled on a firm supporting surface. Depending on the nature
of the supporting surface, it may be necessary to have structural supports under the
outrigger floats or tires to spread the load to a larger bearing surface.
2. For outrigger operation, outriggers shall be fully extended with tires raised free of
crane weight before operating the boom or. hfting loads.
3. If machine Is equipp!'d with front jack cylinder, the front jack cylinder shall be set in
accorda·nce with written procedure.
4. If machine is equipped with extendable counterweight, the counterweight shall be
fully extended before operation.
5. Tires shall be Inflated to the recommended pressure before lifting on rubber.
6. With certain boo", and hoist tackle combinations, maximum capacities may not be
obtainable with standard cable lengths.
OPERATION:
1. Rated loads at rated radius shall not be exceeded. Do not tip the machine to
determine allowable loads. For clamshell or concrete bucket operation, weight of
bucket and load must not exceed 80% of rated lifting capacities.
2. Rated loads do not exceed
85% of the tipping load as determined by SAE Crane
Stability Test Code J·765a.
.
3. Rated loads include the weight of hook blOCk, slings and auxiliary lifting devices and
their weights shall be subtracted from the listed ratings to obtain the net load to be
lifted.
.
4. Load ratings are based on freely suspended loads. No attempt shall be made to move
a load horizontally on the ground.in any dire..ction:
5. Rated loads do not account for wind on lifted load or boom. It Is recommended
when wind velocity is above 20 mph (32 km/h), rated loads and boom lengths shall
be appropriately reduced.
6. Rated loads are for lift crane serVice only.
7. Do not operate at a radius or boom length where capacities are not listed. At these
positions, the machine m ..y overturn without any load on the hook.
8. The maximum load which can be telescoped is not definable because of variations in
loadings and crane maintenan"ce, but it is safe to attempt retraction and extension
within the limits of the capacity chart.
9" When either boom length Or radius or both are between values listed, the smallest
load shown at either the next larger radius or boom length shall be used.
10. For safe operation. the user shall make due allowances for his particular job
conditions, such as: soft or uneven ground, out of level conditions, high winds, side
loads, pendulum .. ction, jerking or sudde"n stopping of loads, hazardous conditions,
experience of personnel, two machine lifts, traveling with toads. electric Wires, etc.
Side pUll on boom or jib is extremely dangerous.
11. Power telescoping boom sections must be extended equally at all times.
12. Handling of personnel from the boom is not authorized except with equipment
furnished and installed by Grove Manufacturing Company.
13. Keep load handling devices a minimum of 12 inches (30 cml below boom head when
lowering or extending boom.
14. Loaded boom angles give an approximation of the operating radIus at specified boom
lengths. The boom angle before loading should be greater to account for deflection.
15. Capacitie~ appearing above bold line are based on structural strength and tipping
should not be relied upon as a capacity limitation.
16. Capacities for 28 ft. (8.6 m) boom length shall be lifted with the b90m fully
retracted. If boom is not fully retracted, capacities shall not exceed those shown for
the 34 ft. (10.4 m) boom length.
17. Lifting loads at close radii directly over the operator's compartment is not recom­
mended.
DEFINITIONS:
1. Operating Radius: Horizontal distance from a projectl"n of the axis of rotation to
the supporting surface before loading to the center of the vertical hoist line or tackle
wilh load applied.
2. Loaded Boom Angle (Shown in Parenthesis on Main Boom Capacity Chart): Is lhe
angle between the boom bose section..a.nd the horizontal, after lifting the rated load
at the rated rad iu s.
3. Working Are.a: Areas measured in a circular arc about the center line of rotation as
shown on the working area diagram.
4. Freely Suspencfed Load: Load' hanging free with no direct external. force applied
except by the lift cable.
5. Side Load: Horizontal force applied to the lifted load either 'on the ground or in the
air.

1. 23' (7.1 m) tele jib length may be used for double line lifting service. 33' (10.1 m)
and 38' (11.6 m) jib lengths may be used for single line lifting service only. Capacities
are based on structural strength of 23' - 38' (7.1 - 11.6 m) tele jib at a given main
boom angle regardless of main boom length.
2. WARNING: Operation of machine with heavier loads than the capacities listed
strictly prohibited. Machine tipping with jib occurs rapidly and without advance
warning.
3. Capacities listed are with fully extended outriggers only.
4. WARNING: Lifting on rUbber with jib is prohibited.
5. Reference radii listed are for fUlly extended boom only 70' (21.2 m).
