CENTERLINE OF ROTATION
1. The operator must read and understand the Owner's Manual before operating this crane.
2. Positioning or operation of crane beyond areas shown on this chart is not intended or approved except where
specified in Owner's Manual.
3. Loaded boom angles at specified boom lengths give only an approximation of the operating radius. The boom angle
before loading should be greater to account for deflections. Do not exceed the operating radius for rated loads.
4. Use rating of next longer boom for boom lengths not shown. Use rating of next greater radius for load radii not shown.
5. Boom must be fully retracted when jib is erected before lowering below minimum angle. Retracted jib has no lifting
capacity below a 50° boom angle.
6. Use rating of next lower boom angle for boom angles not shown on jib load rating chart.
7. Lifting off the main boom point while the swing around jib is erected is not intended or approved.
8. Do not lower boom into this area, as hydraulic pressure will not allow raising the boom without retracting boom first.
9. Crane load ratings on outriggers are based on freely suspended loads with the machine leveled and standing on a firm
uniform supporting surface. No attempt shall be made to move a load horizontally on the ground in any direction.
10. Practical working loads depend on supporting surface, wind and other factors affecting stability such as hazardous
surroundings, experience of personnel, and proper handling, must all be taken into account by the operator.
11. The maximum load which may be telescoped is limited by hydraulic pressure, boom angle, and boom lubrication. It is
safe to attempt to telescope any load within the limits of the load rating chart.
INFORMATION
1. Deductions must be made from rated loads for stowed jib, optional attachments, hooks and loadblocks (see deduction
chart). Weights of slings and other load handling devices shall be considered a part of the load.
2. Crane load ratings with outriggers are based on outriggers and stabilizers extended and set with all load removed
from the carrier wheels.
3. Load ratings do not exceed 85% of tipping load.
DEFINITIONS
1. Operating radius is the horizontal distance from the axis of rotation to the center of the vertical hoist line or load hook
with load suspended.
2. Loaded boom angle as shown in the Load Ratings Chart is the included angle between the horizontal and longitudinal
axes of the boom base after lifting rated load at rated radius.
