10 Ton Telescopic Boom Marine Crane

Where the 10 ton SQ10SA4T fits

The SQ10SA4T is rated to 10,000 kg and still lifts 1,050 kg at 15.5 m, more at full reach than the 8 t model. Choose it for barges, cargo vessels and quays that lift heavy items at mid radius. It needs 63 L/min at 26 MPa from about 37 kW, and weighs 3,250 kg.

Need a folding boom instead? Compare the 10 ton knuckle boom marine crane (SQ10ZA6TJ).

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 SQ10SA4T load chart and the deck space the boom and its rest need when stowed.

Deck mounting dimensions

These figures come from the SQ10SA4T dimension drawing. Your shipyard or naval architect designs the pedestal and the deck reinforcement for the crane’s 3,250 kg self weight and its 25 t·m maximum lifting moment.

We can adapt the mounting to your vessel’s deck, for example by changing the pedestal height. Download the SQ10SA4T dimension drawing (PDF)

Corrosion protection for sea duty

The T in SQ10SA4T 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.

Where the 10 ton SQ10SA5T fits

The SQ10SA5T has a five-section telescopic boom with the hook at the boom head, so it suits deck cargo, barge work and quay handling where the lift stays above deck level. With a self weight of 3,950 kg and a Ø1,000 mm base plate, it is meant for barges, cargo vessels and quays with a strong, engineered pedestal.

With the boom fully extended and raised to 75°, the SQ10SA5T still lifts 1,500 kg at 5 m, which helps when the load has to clear a bulwark, a deck house or a quay edge close to the crane.

Rated capacity always depends on radius. At 9.28 m the SQ10SA5T lifts 2,300 kg and at 12.65 m it lifts 1,550 kg, so check the weight of your heaviest regular load at the distance you need before you choose a tonnage.

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 SQ10SA5T load chart.
