Rated loads include the weight of hook block, slings, and auxiliary lifting devices and their weights shall be subtracted from the listed rating to obtain the net load to be lifted.

All rated loads have been tested to and meet minimum requirements, and do not exceed 85% of the tipping load on outriggers fully and 50% extended, and 75% of the tipping load on outriggers 0% extended (fully retracted) as determined by Crane Stability Test Code.

For clamshell or concrete bucket operation, the weight of bucket and load must not exceed 80% of rated lifting capacities.

Do not tip the machine to determine allowable loads. Rated loads at rated radius shall not be exceeded.Lifting operations risk assessment example Do not travel with crane boom extension or jib erected.With the certain boom and hoist tackle combinations, maximum capacities may not be obtainable with standard cable lengths.Tires shall be inflated to the recommended pressure before lifting on rubber.When equipped with an extendable counterweight, the counterweight shall be fully extended before operation.

If the machine is equipped with a front jack cylinder, the front jack cylinder shall be set in accordance with written procedure.

For outrigger operation, outriggers shall be properly extended with tires raised free of crane weight before operating the boom or lifting loads.

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

The machine shall be leveled on a firm supporting surface.

The operator and other personnel associated with the machine shall fully acquaint themselves with the latest American National Standards Institute (ANSI) Safety Standards for cranes. Operation and maintenance of this machine shall be in compliance with the information in the Operator’s and safety handbook, service manual, and parts Modifications to the machine or the use of optional equipment other than specified may result in a reduced capacity.Ĭonstruction equipment can be hazardous if improperly operated or maintained. The nominal loads shown in the lift chart are for each machine as originally manufactured and equipment.
