0.8 Ton Knuckle Boom Marine Crane

Where the 0.8 ton SQ08ZA3T+1 fits

The SQ08ZA3T+1 has no winch, so loads hang from the boom hook: that suits deck cargo, barge work and quay handling where the lift stays above deck level. With a self weight of 200 kg and a Ø280 mm base plate, it suits workboats, fishing boats and small barges that lift provisions, nets, pumps and spare parts.

Rated capacity always depends on radius. At 2.252 m the SQ08ZA3T+1 lifts 450 kg and at 3.227 m it lifts 300 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 SQ08ZA3T+1 load chart.

Deck mounting dimensions

These figures come from the SQ08ZA3T+1 dimension drawing. Your shipyard or naval architect designs the pedestal and the deck reinforcement for the crane’s 200 kg self weight and its 1.3 t·m maximum lifting moment.

We can adapt the mounting to your vessel’s deck, for example by changing the pedestal height. Download the SQ08ZA3T+1 dimension drawing (PDF)

Corrosion protection for sea duty

The T in SQ08ZA3T+1 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 0.8 ton SQ08ZA3TJ+1 fits

The SQ08ZA3TJ+1 sits at the small end of our knuckle boom marine range. At 220 kg, on a round Ø280 mm base plate, it suits boats where deck space and deck load are both tight: fishing boats, small workboats, pontoons and private jetties that lift nets, pots, outboard engines, stores or a small tender close to the side. It slews 330° and reaches 4.15 m, so place it where both the load and the landing spot sit inside that arc.

If your heaviest load is closer to 1 ton or must go further out, the SQ1ZA3TJ+1 is rated at 1,600 kg and reaches 4.23 m, at 380 kg self weight. Send us the heaviest load, the furthest point it must reach and a deck drawing, and we check them against the load chart.

Corrosion protection for sea duty

The T in SQ08ZA3TJ+1 marks the marine version, which receives a multi-layer anti-rust treatment for salt air and spray. How long a crane lasts on the water 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.
