The SQ3.2ZA3TJ is a 3.2 ton knuckle boom marine crane. It lifts 3,200 kg at 2.1 m, 910 kg at 5.9 m and 680 kg at its full 7.7 m reach, with a 6.8 t·m maximum lifting moment and 360° slewing. It weighs 1,236 kg.
Where the 3.2 ton SQ3.2ZA3TJ fits
The SQ3.2ZA3TJ lifts 3,200 kg near the column and still handles 680 kg at 7.7 m, which covers the full beam of most small workboats. It suits fishing vessels, workboats, small cargo boats and jetties that need a winch to lift from below deck level. Folded it measures 2,271 × 684 mm, so it can sit beside a wheelhouse without blocking the walkway.
Need a longer, straight boom instead? Compare the 3.2 ton telescopic boom marine crane (SQ3.2SA4T).
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 SQ3.2ZA3TJ load chart and the deck space it needs when folded.

We can adapt the mounting to your vessel’s deck, for example by changing the pedestal height. Download the SQ3.2ZA3TJ dimension drawing (PDF)
Corrosion protection for sea duty
The T in SQ3.2ZA3TJ 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 and pins on schedule, and check hoses, fittings and the winch rope for corrosion and wear.
