6.
Determine load radius, boom angle, and boom length.
7.
Compare load weight with chart rated capacity for the boom length, radius,
and boom angle.
8.
The lifted load must not exceed the chart rated capacity for the boom length
and radius.
In this example, the lifted load of 25,300 lbs. is less than the rated load of 27,800 lbs. and
can be handled as long as the machine is on outriggers per Notes 6 & 7, the load stays at
30 feet of radius or less, the conditions of Note 18 are met and the machine is equipped
per Lift Chart specifications.
NOTE:
6. CRANE LOAD RATINGS ARE BASED ON THE CRANE BEING LEVELED
AND STANDING ON FIRM, UNIFORM SUPPORTING SURFACE.
NOTE:
7. CRANE LOAD RATINGS ON OUTRIGGERS ARE BASED ON ALL
OUTRIGGER BEAMS FULLY EXTENDED AND THE TIRES RAISED FREE OF THE
SUPPORTING SURFACE.
NOTE:
18.PRACTICAL WORKING LOADS DEPEND ON THE SUPPORTING
SURFACE, WIND VELOCITY, PENDULUM ACTION, JERKING OR SUDDEN
STOPPING OF LOADS, HAZARDOUS SURROUNDINGS, EXPERIENCE OF
PERSONNEL AND PROPER OPERATION, TIRE INFLATION, TIRE CONDITION,
TRAVELING WITH LOADS, MULTIPLE CRANE LIFTS, PROXIMITY OF ELECTRICAL
WIRES, ETC. APPROPRIATE REDUCTION OF LOAD RATINGS MUST BE MADE
FOR THESE AND ANY OTHER CONDITIONS WHICH MAY AFFECT PRACTICAL
WORKING LOADS.
JIBS
To determine the jib capacities of the crane with all boom lengths, use the following procedure:
1.
Determine weight of load to be lifted.
2.
Determine weight of slings and rigging hardware.
3.
Determine weight of hook block.
4.
Determine capacity deductions.
5.
Calculate weight of lifted load.
6.
Determine jib type and length, jib offset, main boom angle.
7.
Select correct jib load chart (stowaway or sidestow).
8.
Compare load weight with chart rated capacity for the jib length, boom angle,
and jib offset (if applicable).
