The SQZ700 is a 34 ton knuckle boom truck crane with a 70.1 t·m maximum lifting moment. Its 34,000 kg maximum capacity applies close to the crane column; on the load chart it lifts 14,360 kg at 4.4 m, 10,600 kg at 5.8 m and 2,500 kg at its full 20.3 m reach, with 360° slewing. The crane itself weighs 8,500 kg.

What the 34 ton SQZ700 is built for

The SQZ700 is one of the heavy cranes in our knuckle boom range, and it keeps useful capacity far from the truck: 6,050 kg at 9.4 m and 3,290 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 SQZ800 40 ton knuckle boom crane lifts 6,500 kg at 9.4 m and 2,800 kg at 20.3 m.

Load at each radius

4.4 m 14,360 kg
5.8 m 10,600 kg
7.4 m 8,020 kg
9.4 m 6,050 kg
11.4 m 4,800 kg
13.6 m 3,890 kg
15.7 m 3,290 kg
18 m 2,830 kg
20.3 m 2,500 kg

Figures from the SQZ700 load chart with the boom horizontal. Where the chart lists more than one value at a radius, we show the lowest. Do not lift more than the chart shows at your working radius. Download the SQZ700 load chart (PDF)

Mounting it on your truck

The SQZ700 mounts on a truck chassis behind the cab. These are the figures your body builder needs from the dimension drawing:

Width of the crane when stowed 2,550 mm
Height of the crane when stowed 2,450 mm
Length of the crane along the chassis 1,650 mm
Outrigger span 2,250–8,600 mm
Hydraulic supply 90 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 SQZ700 dimension drawing (PDF)

FAQ

Questions about the SQZ700

About the SQZ700

Can the SQZ700 lift 34 tons at full reach?

No. Its 34,000 kg maximum applies only close to the column. On the load chart it lifts 14,360 kg at 4.4 m, and the capacity falls with radius to 2,500 kg at 20.3 m with the boom horizontal. Check the load chart on this page at your working radius.

What size truck does the SQZ700 need?

A heavy truck chassis. The crane weighs 8,500 kg, folds to 2,550 mm wide and 2,450 mm high, takes about 1,650 mm of chassis length, and its outriggers extend from 2,250 mm to 8,600 mm. Send us your truck make, model and wheelbase, and we confirm that the chassis, subframe and payload suit it.

How high can the SQZ700 reach?

With the boom raised, the tip reaches about 23 m above the crane base, and the horizontal reach is 20.3 m. Capacity at height still follows the radius on the load chart.

What hydraulic power does the SQZ700 need?

90 L/min at 35 MPa, about 75 kW, usually taken from the truck’s power take-off. The crane carries a 300 L oil tank.
