The SQ12ZA5 is a 12 ton knuckle boom truck crane. It lifts 12,000 kg at 2.25 m, 5,450 kg at 4.7 m and 1,500 kg at its full 12.2 m reach, with a maximum lifting moment of 27 t·m and 360° slewing. The crane itself weighs 4,600 kg.
What the 12 ton SQ12ZA5 is built for
The SQ12ZA5 folds its boom into a compact package behind the cab: stowed, it is 2,450 mm wide and 2,407 mm high. It needs 1,400 mm of installation space behind the cab. It suits heavy trucks handling steel, precast concrete and machinery, and building sites where loads must be set down well away from the truck.
Rated capacity always depends on radius. At 8.2 m the SQ12ZA5 lifts 2,500 kg and at 10.15 m it lifts 1,850 kg, so check the weight of your heaviest regular load at the distance you need before you choose a tonnage.

Mounting it on your truck
Your body builder mounts the crane on the chassis behind the cab, using these figures from the dimension drawing:
| Installation space behind the cab |
1,400 mm |
| Outrigger span |
2,316–5,706 mm |
| Width of the crane when stowed |
2,450 mm |
| Height of the crane when stowed |
2,407 mm |
| Hydraulic supply |
55 L/min at 28 MPa, about 30 kW |
| Oil tank |
160 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 SQ12ZA5 dimension drawing (PDF)

Choosing the right model
Need more than 12 t? The next class up is the SQZ330 at 16 t. For lighter loads, the SQ10ZA6 at 10 t is the class below.
Before ordering, check that the truck's power take-off can deliver 55 L/min at 28 MPa. We recommend 30 kW of hydraulic power. Its self weight of 4600 kg adds to the load on the truck, so allow for it in the payload.
