1.4GENERAL
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. .
1.5DEFINITIONS
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 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.

1.6SET-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.

1.7OPERATION
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.

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.
