The SQ6.3ZA5 is a 6.3 ton knuckle boom truck crane. It lifts 6,300 kg at 2.1 m, 3,010 kg at 4.4 m and 950 kg at its full 12.2 m reach, with a 13.2 t·m maximum lifting moment and 360° slewing. The crane itself weighs 2,310 kg.
What the 6.3 ton SQ6.3ZA5 is built for
The SQ6.3ZA5 folds its five-section boom into a compact package behind the cab: stowed, the crane is 920 mm wide and 2,322 mm high and needs 1,100 mm of chassis length, so most of the bed stays free for cargo on a medium truck. Unfolded, the knuckle joint lets the boom reach over a wall, a pallet stack or a parked car and set the load down at a low angle, and the telescopic sections run the hook out from 4.4 m to 12.2 m. That suits builders’ merchants delivering blocks, bagged cement and steel, loading small machinery and containers of tools, and utility and maintenance crews. Raised to 75°, the hook reaches about 14.5 m.
Rated capacity always depends on radius. At 6.3 m the SQ6.3ZA5 lifts 2,020 kg, at 8.3 m it lifts 1,500 kg and at 10.2 m it lifts 1,190 kg, so check the weight of your heaviest regular load at the distance you need before you choose a tonnage. If you need a straight boom instead, the 6.3 ton telescopic boom crane is in the same class.

Mounting it on your truck
The SQ6.3ZA5 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 |
1,100 mm |
| Outrigger span |
2,290–5,606 mm |
| Width of the folded crane, outriggers retracted |
920 mm |
| Height of the crane when stowed |
2,322 mm |
| Hydraulic supply |
40 L/min at 28 MPa, about 22 kW |
| Oil tank |
100 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 SQ6.3ZA5 dimension drawing (PDF)

Optional attachments
- Hydraulic gripper opened and closed by its own cylinder to grab and release loads.
- Clamshell bucket for loading, unloading and light digging of waste, chippings and soil.
- Orange peel grab for scrap and bulk material.
- Timber grapple for logs and timber.
- Auger for tree-planting holes, utility poles, foundation piles and soil sampling.
Certification
The SQ6.3Z series holds a CE certificate of conformity under the EU Machinery Directive 2006/42/EC.
Choosing the right model
Need more than 6.3 t? The next class up is the SQ8ZA6 at 8 t. For lighter loads, the SQ5ZA4 at 5 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 22 kW of hydraulic power. Its self weight of 2310 kg adds to the load on the truck, so allow for it in the payload.
