The SQ6.3SA4 is a 6.3 ton telescopic boom truck crane. It lifts 6,300 kg at 2.5 m, 2,800 kg at 4.5 m and 600 kg at its full 12.6 m reach, with a 15.75 t·m maximum lifting moment and 360° slewing. The crane itself weighs 2,600 kg and needs only 850 mm of space behind the cab.
What the 6.3 ton SQ6.3SA4 is built for
The SQ6.3SA4 has a four-section straight boom that runs out from 4.74 m to 12.84 m. Its small footprint suits medium trucks: the crane column is 740 mm wide and it stands 2,441 mm high when stowed, so most of the bed stays free for cargo. Typical work is delivering building materials, pallets and bagged goods, lifting pumps, generators and small machinery, setting precast parts and poles, and roadside maintenance. Raised to 75° with the boom fully extended, the hook reaches about 14.5 m.
Rated capacity always depends on radius. At 7.2 m the SQ6.3SA4 lifts 1,500 kg and at 9.9 m it lifts 1,000 kg, so check the weight of your heaviest regular load at the distance you need before you choose a tonnage. If your loads must go over walls or into tight spots, compare it with the 6.3 ton knuckle boom crane.
Load at each radius
Figures from the SQ6.3SA4 load chart with the boom horizontal. Raising the boom shortens the radius and adds capacity: fully extended to 12.84 m at 75°, it lifts 1,200 kg at 3.3 m. Download the SQ6.3SA4 load chart (PDF)
Mounting it on your truck
The SQ6.3SA4 mounts on a truck chassis behind the cab. These are the figures your body builder needs from the dimension drawing:
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 SQ6.3SA4 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 SQ6.3S 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 SQ8SA5 at 8 t. For lighter loads, the SQ5SA4 at 5 t is the class below.
Before ordering, check that the truck's power take-off can deliver 40 L/min at 20 MPa. We recommend 22 kW of hydraulic power. Its self weight of 2600 kg adds to the load on the truck, so allow for it in the payload.
