3.2 Ton Telescopic Boom Marine Crane

Where the 3.2 ton SQ3.2SA3T fits

The SQ3.2SA3T has a three-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 1,050 kg and a 550 × 550 mm base plate, it suits supply boats, barges and quays that move drums, pallets, small machinery and deck equipment.

With the boom fully extended and raised to 75°, the SQ3.2SA3T still lifts 2,640 kg at 2.15 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 3.5 m the SQ3.2SA3T lifts 1,900 kg and at 5.9 m it lifts 800 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 SQ3.2SA3T load chart.

Deck mounting dimensions

These figures come from the SQ3.2SA3T dimension drawing. Your shipyard or naval architect designs the pedestal and the deck reinforcement for the crane’s 1,050 kg self weight and its 6.8 t·m maximum lifting moment.

We can adapt the mounting to your vessel’s deck, for example by changing the pedestal height. Download the SQ3.2SA3T dimension drawing (PDF)

Corrosion protection for sea duty

The T in SQ3.2SA3T 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 and fittings for corrosion.

Warranty and service

BOB-LIFT covers the whole crane for 12 months. Common spare parts leave the factory within 48 hours, and our service team answers within 12 hours and can guide repairs by video. Cranes ship from Lianyungang, Qingdao or Shanghai.

Where the 3.2 ton SQ3.2SA4T fits

The SQ3.2SA4T reaches 10.5 m with four boom sections, so it can serve boats moored alongside a quay or the far side of a barge deck. It is rated at 3,200 kg close in and 200 kg at full reach, which makes it a reach crane for light loads, not a heavy-lift crane at radius. It weighs 1,250 kg.

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 SQ3.2SA4T load chart and the deck space the boom and its rest need when stowed.
