The SQ6.3SA4T is a 6.3 t telescopic boom marine crane with a maximum lifting moment of 15.75 t·m. It runs on a recommended 22 kW power supply with 40 L/min of hydraulic flow at 20 MPa, weighs 2200 kg and offers 360° slewing.

Why Buy a 6.3 Ton Telescopic Boom Marine Crane?

The 6.3 Ton Telescopic Boom Marine Crane is very reliable and advanced. It is designed from the latest technology and analysis ensuring it works efficiently and reliably. The crane has a compact structure and design, is light, and has a high weight-to-load ration.

This crane has a rack cylinder with an inclined design and a boom that can be folded to maximize the amount of space used. This creates a compact structure and lowers the crane's (and vehicle’s) center of gravity, making it more stable. Additionally, operators can adjust various parameters on the crane to make it more efficient and comfortable to use.

The 6.3 Ton Telescopic Boom Marine Crane is also designed for easy attachment additions making it better when finding solutions for new challenges. This helps reduce the cost of use. Lastly, buyers enjoy great after-sales service with quick feedback and deliveries (accessories).
