OPERATION
8000 SERIES OWNER’S MANUAL
The 8000 crane is designed to provide excellent service if operated within the maximum allowable load
specifications stated on the unit’s “Angle Indicator Plate” located on either side of the boom. load charts are also
included on pages 6 and 7. The load information charts should be studied before operating the crane. Exceeding
the stated load limit can cause tipping or structural failure. You should familiarize yourself with proper operation
procedures to avoid overloading the crane. As an example: If a load of 5000 pounds were lifted at an 11’ boom
length at 30°, lowering the boom would cause an overload situation.
The 8000 crane is relatively simple to operate. Prior to field use, you should familiarize yourself with the controls
and how the unit reacts to the controls. Practice operations should be performed with a light test weight
progressing to a heavier test weight.

•
Insert cable through the snatch block by removing the cotter pin and disassembling.
•
Reassemble the snatch block. Be sure to reinsert the cotter pin in the snatch block.
You should also use a “two-part” line for loads under 4000 pounds if you want to slow down the line speed of
the cable.

It must be understood that all load ratings are formulated on 85% of tipping. Tipping is defined as a tire breaking
contact with the ground. Furthermore, all load ratings are dependent upon compliance with the following:

The unit has been correctly installed in accordance with chassis requirements and truck body manufacturer’s
specifications.
