1.4 GENERAL
1. Rated loads as shown on Lifting 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 and Maintenance and Service 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 read the Operator’s Manual .
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

4. FREELY SUSPENDED LOAD – Load hanging

except by the hoist rope.
THESE LINES DETERMINE THE LIMITS OF
WORKING POSITIONS WHITCH CORRESPOND TO
THOSE SHOWN ON THE CRANE CAPACITY CHART.

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
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.
RT60 Rough Terrain Crane 01 - 3
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 or Maintenance and Service 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
Maintenance and Service 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
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.
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.
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.
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)).
7. Rated loads do not exceed 85% on outriggers or 75% on tires, of the tipping load as
determined by ASME/ANSI B30.5.
8. Rated loads are based on freely suspended loads. No attempt shall be made to drag a
load horizontally on the ground in any direction.
RT60 Rough Terrain Crane 01 - 5
9. 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.
10. Load ratings are dependent upon the crane being maintained according to
manufacturer’s specifications.
11. It is recommended that load handling devices, including hooks, and hook blocks, be
kept away from boom head at all times.
