The SQ6.3SA4T is a 6.3 ton telescopic boom marine crane. It lifts 6,300 kg at 2.5 m, 1,500 kg at 7.2 m and 600 kg at its full 12.6 m reach, with a 15.75 t·m maximum lifting moment and 360° slewing. It weighs 2,200 kg.
Where the 6.3 ton SQ6.3SA4T fits
The SQ6.3SA4T is rated to 6,300 kg and 15.75 t·m and lifts 600 kg at 12.6 m. Its predecessor, the SQ6.3SA3T, lifts netted bundles of bagged cargo from a moored cargo vessel in the Maldives. It suits cargo vessels, barges and quays that move bagged or palletised cargo between deck and shore.

We size a marine crane by the load and the radius you need, not by vessel length. Send us the heaviest load, the furthest point it must reach and a deck drawing, and we check them against the SQ6.3SA4T load chart and the deck space the boom and its rest need when stowed.
Deck mounting dimensions
These figures come from the SQ6.3SA4T dimension drawing. Your shipyard or naval architect designs the pedestal and the deck reinforcement for the crane’s 2,200 kg self weight and its 15.75 t·m maximum lifting moment.
We can adapt the mounting to your vessel’s deck, for example by changing the pedestal height. Download the SQ6.3SA4T dimension drawing (PDF)
Corrosion protection for sea duty
The T in SQ6.3SA4T marks the marine version, which receives a multi-layer anti-rust treatment for salt air and spray. How long a crane lasts in a harbour still depends on routine care: rinse it with fresh water after salt-water work, grease the slewing bearing, the boom pins and the slide pads of the telescopic sections on schedule, and check hoses and fittings for corrosion.
