WARNING: THIS CHART IS ONLY A GUIDE.

The notes below are for illustration only and
should not be relied upon to operate the crane. Outriggers Transmission
The individual crane's load chart, operating
instructions and other instruction plates must be
read and understood prior to operating Outrigger Controls Axles
the crane.

1. All rated loads meet ANSI/ASME B30.5, Mobile Engine Brakes

and Locomotive Cranes. Testing and development
were performed to SAEJ1063, Cantilevered Boom
Crane Structures - Method of Test and SAEJ765 Fuel Tank Capacity Tires
Crane Stability Test Code.

2. Capacities given do not include the weight of

Electrical System Suspension
hook blocks, slings, auxiliary lifting equipment and
load handling devices. Their weights must be
added to the load to be lifted. When more than
Drive Rotation
minimum required reeving is used, the additional
rope weight shall be considered part of the load.

3. The machine shall be leveled on a firm Lights Boom Elevation

supporting surface. Depending on the nature of the
supporting surface, it may be necessary to have
structural supports under the outrigger floats to Cab Swing
spread the load to a larger bearing surface.

4. When either boom length or radius or both are Boom Counterweight

between values listed, the smallest load shown at
either the next larger radius or next longer or
shorter boom length shall be used. Fixed Swingaway

5. For outrigger operation, outriggers shall be

properly extended with tires raised off the ground Tele-Swingaway Hydraulic System
