The SQ3.2ZA4 is a 3.2 ton knuckle boom truck crane. It lifts 3,200 kg at 2.1 m, 1,350 kg at 4.4 m and 520 kg at its full 9.4 m reach, with a 6.8 t·m maximum lifting moment and 400° slewing. The crane itself weighs 1,450 kg.
What the 3.2 ton SQ3.2ZA4 is built for
The SQ3.2ZA4 folds its four-section boom into a compact package behind the cab: stowed, it is 2,450 mm wide and 2,040 mm high and needs only 850 mm of chassis length, so it fits light and medium trucks and leaves most of the bed free for cargo. With four boom sections it reaches 9.4 m, yet the crane weighs only 1,450 kg. That suits light trucks delivering building materials, garden and landscaping supplies and small equipment, and municipal service fleets. With the boom raised, the tip reaches about 11.3 m above the crane base.
Rated capacity always depends on radius. At 6 m the SQ3.2ZA4 lifts 910 kg and at 7.8 m it lifts 680 kg, so check the weight of your heaviest regular load at the distance you need before you choose a tonnage. If you need more capacity close to the truck, the SQ4ZA3 4 ton knuckle boom crane lifts 1,750 kg at 4.35 m.

Mounting it on your truck
The SQ3.2ZA4 mounts on a truck chassis behind the cab. These are the figures your body builder needs from the dimension drawing:
| Installation space behind the cab |
850 mm |
| Outrigger span |
2,250–3,513 mm |
| Width of the crane when stowed |
2,450 mm |
| Height of the crane when stowed |
2,040 mm |
| Hydraulic supply |
25 L/min at 25 MPa, about 14 kW |
| Oil tank |
60 L |

Certification
The SQ3.2Z series holds a CE certificate of conformity under the EU Machinery Directive 2006/42/EC.
Choosing the right model
Need more than 3.2 t? The next class up is the SQ4ZA4 at 4 t. For lighter loads, the SQ2ZA4 at 2 t is the class below.
Before ordering, check that the truck's power take-off can deliver 25 L/min at 25 MPa. We recommend 14 kW of hydraulic power. Its self weight of 1450 kg adds to the load on the truck, so allow for it in the payload.
