The SQ1ZA4 is a 1.6 ton knuckle boom truck crane. It lifts 1,600 kg at 1.39 m, 990 kg at 2.3 m and 180 kg at its full 4.23 m reach, with a maximum lifting moment of 2.2 t·m and 330° slewing. The crane itself weighs 490 kg.
What the 1.6 ton SQ1ZA4 is built for
The SQ1ZA4 folds its boom into a compact package behind the cab: stowed, it is 1,750 mm wide and 1,760 mm high. It needs 550 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 3.25 m the SQ1ZA4 lifts 470 kg and at 4.23 m it lifts 180 kg, so check the weight of your heaviest regular load at the distance you need before you choose a tonnage.

Choosing the right model
Need more than 1.6 t? The next class up is the SQ2ZA4 at 2 t.
Before ordering, check that the truck's power take-off can deliver 15 L/min at 18 MPa. We recommend 7.5 kW of hydraulic power. Its self weight of 490 kg adds to the load on the truck, so allow for it in the payload.
