HOIST DRUM PERFORMANCE
**Single Line Pull reflects the maximum hydraulic capacity of the hoist unit at the given layer and range setting. The allowable single line pull may be limitedby the strength of the hoist rope. See load hoisting table for rope limitations.

CRANE RATING DATA
! WARNINGThis rating chart is invalid if the crane has been modified or altered by use of other than GENUINE AMERICANPARTS as such modifications or alterations may affect its capacity or safe operation. See American CraneCorporation Service Bulletin #259.
The ratings in this chart are for planning purposes only. Only those ratings specifically assigned to a crane andmounted in the operator’s cab or in the Operator’s Manual should be used for actual operation.
Ratings in this chart are in POUNDS and do not exceed the percentage of tipping specified for this crane by ANSI B30.5. Allratings require that the crane be standing level on a firm uniformly supporting surface.
Do not lift loads in excess of those shown on this chart. Lifting loads in excess of those shown or operation not in accordancewith good operating practice, including limitations shown on page 3499 of Operator’s Manual, can cause tipping, structuraldamage or catastrophic failure.
Asterisk (*) areas on this chart indicate ratings which are limited by strength of material or factors other than stability (tipping).
RADIUS IN FEET is the horizontal distance at ground level from the crane centerline of rotation to a vertical line through thecenter of gravity of the suspended load.
When using the main boom fall with jib in place, the main fall ratings must be reduced by the jib effective weight shown on thejib rating chart plus twice the weight of all suspended blocks, slings, rope, etc., at the jib fall.
When using the main boom fall with boom tip extension in place, the main fall ratings must be reduced by the weight of theboom tip extension plus twice the weight of all suspended blocks, slings, rope, etc., at the boom tip extension fall.
Blocks, slings, buckets and other load carrying devices are considered part of the load. The weight of standard hoisting ropesfor the rating at a given radius has been calculated as part of the boom point load and need not be considered in determiningnet allowable loads.
Ratings shown on this chart make no allowance for such factors as out of plumb loads, wind, poor soil conditions, improperinflation of rubber tires and dynamic effects due to excessive operating speeds. The user (operator) must exercise judgementto make allowance for these conditions. See page 3499 of Operator’s Manual for detailed information.
No account is taken of the wind force on the load. This effect, which can be substantial for loads with large surface areas,must be considered by the user. In any wind it is strongly recommended that taglines be used to control the load.
BOOM HOIST LINE is 12 parts of 5/8 inch diameter EIPS wire rope with a minimum breaking strength of 41,200 pounds.
PENDANT SUSPENSION LINE is 2 parts of 1-1/4 inch diameter MONOLAY wire rope with a minimum breaking strength of172,800 pounds.
MAIN LOAD LINE is 7/8 inch diameter EIPS wire rope with a minimum breaking strength of 79,600 pounds.
WHIP LINE is 7/8 inch diameter IPS wire rope with a minimum breaking strength of 69,200 pounds.
ERECTION
Erection is with the A-Frame fully raised. Erection “OVER THE END” is with the boom over the idler end. Erection “OVERTHE SIDE” is with the boom 90° to the sideframes and with the side frames extended. Blocks, slings and other load carryingdevices must be on the ground during erection.
