1.4 GENERAL
1. Rated loads as shown on Lift Charts pertain to this machine as originally
manufactured and equipped. Modifications 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 maintained.
Operation and maintenance of this machine shall be in compliance with the
information in the Operator’s Manual supplied with this machine. If these manuals are
missing, order replacements from the manufacturer through your distributor.
3. These warnings do not constitute all of the operating conditions for the crane. The
operator and job site supervision must fully understand the Operator’s Manual for the
crane.
4. This crane and its load ratings are in accordance with ASME/ANSI B30.5.
1.5 DEFINITIONS
1. LOAD RADIUS – The horizontal distance from the axis of rotation before loading to
the center of the vertical hoist line or tackle with a load applied.
2. LOAD BOOM ANGLE – It is the angle between the boom base section and the
horizontal, after lifting the rated load at the rated radius. The boom angle before
loading should be greater to account for deflections. The loaded boom angle
combined with the boom length give only an
approximation of the operating radius.
3. WORKING AREA – Areas measured in a
circular arc about the centerline of rotation as
shown in the diagram.
4. FREELY SUSPENDED LOAD – Load hanging
free with no direct external force applied except
by the hoist rope.
5. SIDE LOAD – Horizontal force applied to the lifted load either on the ground or in the
air;
6. EXTRA-CAUTION ZONE – Tipping can occur with some boom/jib combinations at
01 - 2 RT75 Rough Terrain Crane
radii within this area without any load on the hook.
7. BOOM SIDE OF CRANE – The side of the crane over which the boom is positioned
when in an OVER SIDE working position.
1.6 SET-UP
1. Crane load ratings are based on the crane being leveled and standing on a firm and
uniform supporting surface.
2. Crane load ratings on outriggers are
based on all outrigger beams being fully
extended / retracted, or in the case of
partial extension ratings mechanically
pinned in the appropriate position, and
the tires raised free of the supporting
surface.
3. Crane load ratings on tires depend on appropriate inflation pressure and the tire
conditions. Caution must be exercised when increasing air pressures in tires. Consult
Operator’s Manual for precautions.
4. Consult appropriate section of the Operator’s Manual for more exact description of
hoist line reeving.
5. The use of more parts of line than required by the load may result in having insufficient
rope to allow the hook block to reach the ground.
6. Properly maintained wire rope is essential for safe crane operation. Consult
Operator’s Manual for proper maintenance and inspection requirements.
7. When spin-resistant wire rope is used, the allowable rope loading shall be the
breaking strength divided by five (5), unless otherwise specified by the wire rope
manufacturer.
1.7 OPERATION
1. CRANE LOAD RATINGS MUST NOT BE EXCEEDED. DO NOT ATTEMPT TO TIP
THE CRANE TO DETERMINE ALLOWABLE LOADS.
2. When either radius or boom length, or both, are between listed values, the smaller of
the two listed load ratings shall be used.
3. Do not operate at longer radii than those listed on the applicable Lift Chart (cross
hatched areas shown on range diagrams) as tipping can occur without a
load on the hook.
4. The boom angles shown on the Lift Charts give an approximation of the operating
radius for a specified boom length. The boom angle, before loading, should be greater
to account for boom deflection. It may be necessary to retract the boom if maximum
RT75 Rough Terrain Crane 01 - 3
boom angle is insufficient to maintain rated radius.
5. All telescopic sections must be extended synchronically.
6. Rated loads include the weight of hook block, slings,
and auxiliary lifting devices. Their weights shall be
subtracted from the listed rated load to obtain the
net load that can be lifted.
7. When lifting over the jib, the weight of any hood
block, slings, and auxiliary lifting devices at the
boom head must be added to the load.
8. Rated lifting capacities are based on correct reeving. Deductions must be made for
excessive reeving. Any reeving over the minimum required, (see Hoist Tackle Chart),
is considered excessive and must be accounted for. Deduct for each meter of
excessive wire rope before attempting to lift a load.
9. When jibs are erected but unused, add three (3) times the weight of jib, any hook
block, slings, and auxiliary lifting devices at the jib head to the load (jib weight: 952 kg
(2099 lbs)).
10. Rated loads do not exceed 85% on outriggers or 75% on tires, of the tipping load as
determined by ASME/ANSI B30.5.
11. Rated loads are based on freely suspended loads. No attempt shall be made to drag a
load horizontally on the ground in any direction.
12. The user shall operate at reduced ratings to allow for adverse job conditions, such as:
soft or uneven ground, out of level conditions, high winds, side loads, pendulum action,
jerking or sudden stopping off loads, hazardous conditions, experience of personnel,
two-machine lifts, traveling with loads, electric wires, etc, (side pull on boom or jib is
hazardous). If wind speed is higher than the maximum permissible value (45 ft/s (13.8
m/s), grade 6) or it is fulminous during crane operation, stop working and completely
retract the boom and place it on the boom support for traveling.
13. Load ratings are dependent upon the crane being maintained according to
manufacturer’s specifications.
14. It is recommended that load handling devices, including hooks, and hook blocks, be
kept away from boom head at all times.

SET-UP
1. Crane load ratings are based on the crane being leveled and standing on a firm and uniform
supporting surface.
2. Crane load ratings on outriggers are based on all outrigger beams being fully extended /
retracted, or in the case of partial extension ratings mechanically pinned in the appropriated
position, and the tyres raised free of the supporting surface.
OPERATION
1. CRANE LOAD RATINGS MUST NOT BE EXCEEDED. NO ATTEMPT TO TIP THE CRANE TO
DETERMINE ALLOWABLE LOADS.
2. When either radius or boom length, or both, are between listed values, the smaller of the two
listed load ratings shall be used.
3. EXTRA-CAUTION ZONE – Tipping can occur with some boom/jib combinations at radii within
this area without any load on the hook.
4. The boom angles shown on the Lift Charts give an approximation of the operation radius for a
specified boom length. The boom angle, before loading, should be greater to account for boom
deflection. It may be necessary to retract the boom if maximum boom angle is insufficient to
maintain rated radius.
5. Rated Loads include the weight of hook block, slings and auxiliary lifting devices. Their weights
shall be subtracted from the listed rated load to obtain the net load that can be lifted. Rated lift
ratings are based on correct reeving. Deductions must be made for excessive reeving. Any
reeving over the minimum is considered excessive. Deduct for each foot of excessive wire rope
before attempting to lift a load. See HOIST TACKLE CHART for rope information.
6. All telescopic sections must be extended synchronically.

02 - 6 RT75 Rough Terrain Crane
SET-UP
1. Crane load ratings are based on the crane being leveled and standing on a firm and uniform
supporting surface.
2. Crane load ratings on outriggers are based on all outrigger beams being fully extended /
retracted, or in the case of partial extension ratings mechanically pinned in the appropriate
position, and the tyres raised free of the supporting surface.
OPERATION
1. CRANE LOAD RATINGS MUST NOT BE EXCEEDED. NO ATTEMPT TO TIP THE CRANE TO
DETERMINE ALLOWABLE LOADS.
2. When either radius or boom length, or both, are between listed values, the smaller of the two
listed load ratings shall be used.
3. EXTRA-CAUTION ZONE – Tipping can occur with some boom/jib combinations at radii within
this area without any load on the hook.
4. The boom angles shown on the Lift Charts give an approximation of the operation radius for a
specified boom length. The boom angle, before loading, should be greater to account for boom
deflection. It may be necessary to retract the boom if maximum boom angle is insufficient to
maintain rated radius.
5. Rated Loads include the weight of hook block, slings and auxiliary lifting devices. Their weights
shall be subtracted from the listed rated load to obtain the net load that can be lifted. Rated lift
ratings are based on correct reeving. Deductions must be made for excessive reeving. Any
reeving over the minimum is considered excessive. Deduct for each foot of excessive wire rope
before attempting to lift a load. See HOIST TACKLE CHART for rope information.
6. When lifting over the jib, the weight of any hook block, slings, and any auxiliary lifting devices at
the boom head must be added to the load.
7. For all boom lengths less than the maximum with the jib erected, the rated loads are determined
by boom angle only in the appropriate column.
8. For all boom lengths less than the listed boom length, the rated load is to be determined by boom
angle.

SET-UP
1. Crane load ratings are based on the crane being leveled and standing on a firm and uniform
supporting surface.
2. Crane load ratings on tires depend on appropriate inflation pressure and tire condition.
Caution must be exercised when increasing air pressures in tires. Consult Operator’s Manual
for precautions.
3. Use of jib is not permitted for pick-and-carry operations.

OPERATION
1. CRANE LOAD RATINGS MUST NOT BE EXCEEDED. NO ATTEMPT TO TIP THE CRANE
TO DETERMINE ALLOWABLE LOADS.
2. When radius is between listed values, the smaller of the two listed load ratings shall be used;
3. Do not operate at longer radii than those listed on the applicable Lift Chart as tipping can
occur without a load on the hook.
4. All telescopic sections must be extended synchronously.
5. Without outriggers, never maneuver the boom beyond listed load radii for applicable tires
used to ensure stability.
6. Creep speed is crane movement of less than 61 m in 30-minutes period and not exceeding
1.6 KM/H.
