Important lifting capacity

The headline capacity is 25 tonnes, but 25 tonnes is only available at a short working radius and with the appropriate boom/reeving configuration. As the working radius and boom length increase, the permissible load decreases. The manufacturer’s load chart must therefore be used for every lift.
