* Limited by hydr. capacity
The lift capacities on the load lift hook of the Liebherr quick coupler SW33 without working tool are stated in metric tons (t) and are valid on a firm, level supporting surface with blocked
oscillating axle. These capacities can be slewed through 360° with the undercarriage in the transverse position. Capacities in the longitudinal position of the undercarriage (+ / – 15°)
are specified over the steering axle with the stabilizers raised and over the rigid axle with the stabilizers down. The values apply when the adjusting cylinder is in the optimal position.
Indicated loads based on the ISO 10567 standard and do not exceed 75 % of tipping or 87 % of hydraulic capacity, or are limited by the permissible load of the load lift hook on the quick
coupler (max. 5 t). Without the quick coupler, lift capacities will increase by up to 110 kg.
In accordance with the harmonised European Standard EN 474-5, hydraulic excavators used for lifting operations must be equipped with pipe fracture safety valves, an overload w
­ arning
device, a load lift hook and a lift capacity chart.
