The SQZ430 is a 20 t knuckle boom truck-mounted crane with a maximum lifting moment of 42.3 t·m. It runs on a recommended 45 kW power supply with 63 L/min of hydraulic flow at 33 MPa, weighs 5500 kg and has a rated slewing angle of 360°.

Buyers often search for this machine as a 20 ton truck crane or crane truck. The SQZ430 is a loader crane fitted behind the cab, so the truck keeps its cargo body and carries the goods it lifts. That makes it different from a mobile truck crane, which has its own carrier and no cargo deck. We ship the SQZ430 on its own for mounting on your truck; we have fitted our cranes to Dongfeng, Isuzu and Sinotruk trucks.

Why Should You Purchase the 20 Ton Knuckle Boom Truck Mounted Crane?

BOB-LIFT have manufactured the 20 Ton Knuckle Boom Truck Mounted Crane using premium parts and technology, making it more efficient for users. The crane has several features that make it a great piece of machinery for various tasks.

The 20 Ton Knuckle Boom Truck Mounted Crane is much lighter than its competition and has a good load ratio. It has square legs that protect the cylinder and provide additional support when lifting weight that’s above 6.3T.

Additionally, the crane has a better lifting capacity due to its link-rod system. Its outer boom can manage a negative elevation angle and provides more lifting space. It has a telescopic boom with coupling technology that makes it more efficient. It also has a symmetrical central design with a hexagonal boom that prevents it from bending under extreme weight.

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 SQZ430 series holds a CE certificate of conformity under the EU Machinery Directive 2006/42/EC.
