The SQ12ZA6 is one of 21 models in our Knuckle Boom Truck Mounted Cranes range, which runs from 1.6 t to 40 t.

The SQ12ZA6 is a 12 t knuckle boom truck-mounted crane with a maximum lifting moment of 27 t·m. It runs on a recommended 30 kW power supply with 55 L/min of hydraulic flow at 28 MPa, weighs 4800 kg and offers continuous 360° slewing.

Why Purchase this Crane?

These impressive machines have become essential in industries, including construction, forestry, shipping and logistics.

The 12 ton knuckle boom crane is highly favored by professionals and one of its standout features is the articulating arm, which consists of sections resembling a knuckle. This unique design provides flexibility and reach, making it perfect for navigating tight spaces or reaching over obstacles.

In addition, its small size and flexibility are ideal for construction sites in confined spaces with limited room. The crane's precise controls allow operators to perform lifts effortlessly minimizing the chances of accidents or harm to loads. The crane has advanced safety features, like load monitoring systems and stability control mechanisms. These technologies play a role in enhancing safety during operations providing protection, for both workers and equipment.

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 SQ12Z series holds a CE certificate of conformity under the EU Machinery Directive 2006/42/EC.

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 4800 kg adds to the load on the truck, so allow for it in the payload.
