The SQZ800 is a 40 ton knuckle boom truck crane with an 80 t·m maximum lifting moment. Its 40,000 kg maximum capacity applies close to the crane column; on the load chart it lifts 14,500 kg at 4.4 m, 11,500 kg at 5.8 m and 2,800 kg at its full 20.3 m reach, with 360° slewing. The crane itself weighs 9,000 kg.
What the 40 ton SQZ800 is built for
The SQZ800 is one of the heavy cranes in our knuckle boom range, and it keeps useful capacity far from the truck: 6,500 kg at 9.4 m and 3,550 kg at 15.7 m. Stowed, it folds to 2,550 mm wide and 2,450 mm high and takes about 1,650 mm of chassis length behind the cab. It needs a heavy truck chassis with a strong subframe, and suits steel and precast concrete delivery, lifting heavy machinery, generators and transformers, and building and infrastructure sites. With the boom raised, the tip reaches about 23 m above the crane base.
Rated capacity always depends on radius, so check the weight of your heaviest regular load at the distance you need before you choose a tonnage. For comparison, the SQZ1000 50 ton knuckle boom crane lifts 7,300 kg at 10 m and 3,230 kg at 20.3 m.

2,450 mm |
| Length of the crane along the chassis |
1,650 mm |
| Outrigger span |
2,250–8,600 mm |
| Hydraulic supply |
100 L/min at 35 MPa, about 75 kW |
| Oil tank |
300 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 SQZ800 dimension drawing (PDF)
