Lift Capacities EEC-0046 V1.1
Lift Capacities
Overloading this crane or disregarding Lift Capacity Chart directions can result in
structural failure, tipping or injury to personnel. Read and understand all instructions
before operating the crane.
Do not lift any load without determining the total load lifted. The lifted load must
always include the headache ball/hook block and any chains, slings, spreader bars etc.
used to pick the load.
For the main boom, the boom length and load radius shall determine the
capacity. Boom angle should only be used as a guide. Always measure the load
radius. For the jib, the boom angle shall determine the capacity on the jib until full
extension is reached. Do not exceed radius indicated on the load chart at full boom
extension .
Main boom and jib load ratings above the heavy line on the Capacity Chart are
based on structural strength and not stability. The main boom and jib load ratings below
the heavy line are based on stability and do not exceed 85 percent of tipping.
Before lifting any load, make sure that:
A. Outriggers and stabilizers are extended on a firm, uniformly supporting surface.
B. Crane is level.
C. The exact weight lifted is known.
D. The weight of the stored jib, hook block/headache ball, slings, chains and all
other load handling devices are deducted from the load ratings on the Capacity
Chart.
E. Due to wear pad friction, some loads on the chart cannot be telescoped.
However, it is safe to attempt to telescope all loads within the chart limits.
F. Do not exceed the area of operation on the capacity chart.
