Establishing Load Ratings
The structure of the Extreme auto processor grapple head attachment is designed to lift a load that
meets or exceeds the excavator’s boom lift capacity, when hydraulic pressure of between 80% and
100% of maximum pressure per the label on Extreme grapple head attachment is supplied by the excava-
tor, the Extreme’s grapple mechanism to adequately engage the item lifted.
The lift limitations set forth by the excavator OEM (Original Equipment Manufacturer) must be reviewed
and understood by the operator. The excavator OEM operator manual or in cab label is expected to pro-
vide a chart with lifting capacities at a variety of lift positions,
in accordance with ISO 10567:2007
The op-
erator must apply the weight of the Extreme grapple head assembly and interpret the excavator OEM
chart whereas the position of the dozer blade or stabilizers are considered to be off the ground to deter-
mine the permissible load.
Sample chart. This chart does not contain any valid lift capacities for any excavator equipped with an
Extreme auto processor attachment.
In accordance with typical excavator OEM lifting charts, with general reference to sample chart
above, positions that effectively reduce the load threshold at which tipping occurs, include:
●Lifting dozer blade, downriggers or Extreme hold down arm, as shown in sample illustration (B) or (C).
●Turning of excavator’s cab across tracks or wheels with the dozer up, shown in sample illustration (C).
●Extending the reach of the boom and stick.
Operator must identify load chart for specific excavator, not included herein, and use limits per
the chart which specifies ‘dozer up and side lift’ or ‘outriggers up and side lift’, and subtract
weight of Extreme grapple head assembly, to identify the net lift capacity permissible.
