The SQ5ZA4 is a 5 ton knuckle boom truck crane. It lifts 5,000 kg at 2.1 m, 2,350 kg at 4.45 m and 700 kg at its full 9.9 m reach, with a 10.5 t·m maximum lifting moment and 400° slewing. The crane itself weighs 2,386 kg.
What the 5 ton SQ5ZA4 is built for
The SQ5ZA4 folds its four-section boom into a compact package behind the cab: stowed, it is 2,492 mm wide and 2,357 mm high and needs only 1,050 mm of chassis length, so it fits medium trucks and leaves most of the bed free for cargo. 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. That suits builders’ merchants delivering blocks, bagged cement and timber, loading small machinery, and utility and maintenance crews. Raised to 75°, the hook reaches about 12 m.
Rated capacity always depends on radius. At 6.2 m the SQ5ZA4 lifts 1,600 kg and at 8.05 m it lifts 1,100 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 5 ton telescopic boom crane is in the same class.

Mounting it on your truck
The SQ5ZA4 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 |
1,050 mm |
| Outrigger span |
2,272–5,122 mm |
| Width of the crane when stowed |
2,492 mm |
| Height of the crane when stowed |
2,357 mm |
| Hydraulic supply |
35 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 SQ5ZA4 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 SQ5Z series holds a CE certificate of conformity under the EU Machinery Directive 2006/42/EC.
Choosing the right model
Need more than 5 t? The next class up is the SQ6.3ZA5 at 6.3 t. For lighter loads, the BLZ90K5 at 4.6 t is the class below.
Before ordering, check that the truck's power take-off can deliver 35 L/min at 28 MPa. We recommend 22 kW of hydraulic power. Its self weight of 2386 kg adds to the load on the truck, so allow for it in the payload.
