The SQ8ZA6 is an 8 ton knuckle boom truck crane. It lifts 8,000 kg at 2 m, 3,700 kg at 4.51 m and 850 kg at its full 14.68 m reach, with a 16 t·m maximum lifting moment and 360° slewing. The crane itself weighs 3,450 kg.
What the 8 ton SQ8ZA6 is built for
The SQ8ZA6 folds its six-section boom into a compact package behind the cab: stowed, it is 2,460 mm wide and 2,340 mm high, so most of the truck bed stays free for cargo. Unfolded, the knuckle joint lets the boom reach over a wall, a stack of material or a parked vehicle and set the load down at a low angle, which suits delivering blocks, steel and building materials to sites, loading machinery, and utility and maintenance work. Raised to 84°, the hook reaches about 17 m.
Rated capacity always depends on radius. At 8.51 m the SQ8ZA6 lifts 1,820 kg and at 10.56 m it lifts 1,420 kg, so check the weight of your heaviest regular load at the distance you need before you choose a tonnage. The SQ8ZA6+1 version adds one manual jib section for 16.8 m maximum radius and 650 kg at full reach, at 3,500 kg self weight. If you need a straight boom instead, the 8 ton telescopic boom crane is in the same class.

Mounting it on your truck
The SQ8ZA6 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 |
1,153 mm |
| Outrigger span |
2,310–5,610 mm |
| Width of the crane when stowed |
2,460 mm |
| Height of the crane when stowed |
2,340 mm |
| Hydraulic supply |
40 L/min at 28 MPa, about 25 kW |
| Oil tank |
160 L |
Send us your truck make, model and wheelbase, and we check that the chassis and power take-off suit the crane before you order. Download the SQ8ZA6 dimension drawing (PDF)

Certification
The SQ8Z series holds a CE certificate of conformity under the EU Machinery Directive 2006/42/EC.
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 3450 kg adds to the load on the truck, so allow for it in the payload.
