The SQ2ZA2 is a 2 ton knuckle boom truck crane. It lifts 2,000 kg at 2.1 m, 1,000 kg at 4.1 m and 750 kg at its full 5.1 m reach, with a maximum lifting moment of 4.2 t·m and 370° slewing. The crane itself weighs 650 kg.
What the 2 ton SQ2ZA2 is built for
The SQ2ZA2 folds its boom into a compact package behind the cab: stowed, it is 1,920 mm wide and 1,796 mm high. It needs 650 mm of installation space behind the cab. It suits small trucks and pickups delivering building materials, gas cylinders and garden supplies, and service vehicles that lift pumps, engines and tools.
Rated capacity always depends on radius. At 4.1 m the SQ2ZA2 lifts 1,000 kg and at 5.1 m it lifts 750 kg, so check the weight of your heaviest regular load at the distance you need before you choose a tonnage.

1,870–3,020 mm |
| Width of the crane when stowed |
1,920 mm |
| Height of the crane when stowed |
1,796 mm |
| Hydraulic supply |

Choosing the right model
Need more than 2 t? The next class up is the SQ3.2ZA3 at 3.2 t. For lighter loads, the SQ1ZA3+1 at 1.6 t is the class below.
Before ordering, check that the truck's power take-off can deliver 20 L/min at 20 MPa. We recommend 9 kW of hydraulic power. Its self weight of 650 kg adds to the load on the truck, so allow for it in the payload.
