Choosing the right model
Need more than 8 t? The next class up is the SQ10ZA6 at 10 t. For lighter loads, the SQ6.3ZA5 at 6.3 t is the class below.
Before ordering, check that the truck's power take-off can deliver 40 L/min at 28 MPa. We recommend 25 kW of hydraulic power. Its self weight of 3050 kg adds to the load on the truck, so allow for it in the payload.
