10 Ton Knuckle Boom Marine Crane

Where the 10 ton SQ10ZA5T fits

The SQ10ZA5T 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 2,780 kg and a Ø1,000 mm base plate, it is meant for barges, cargo vessels and quays with a strong, engineered pedestal.

Rated capacity always depends on radius. At 8.51 m the SQ10ZA5T lifts 2,280 kg and at 10.56 m it lifts 1,800 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 SQ10ZA5T load chart.

Load at each radius

Figures from the SQ10ZA5T load chart with the boom horizontal. Do not lift more than the chart shows at your working radius. Download the SQ10ZA5T load chart (PDF)

Deck mounting dimensions

These figures come from the SQ10ZA5T dimension drawing. Your shipyard or naval architect designs the pedestal and the deck reinforcement for the crane’s 2,780 kg self weight and its 21 t·m maximum lifting moment.

We can adapt the mounting to your vessel’s deck, for example by changing the pedestal height. Download the SQ10ZA5T dimension drawing (PDF)

Corrosion protection for sea duty

The T in SQ10ZA5T 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 10 ton SQ10ZA5TJ fits

The SQ10ZA5TJ has a winch on the boom, so the hook hangs from a rope: that helps when loads go down into a hold or onto a boat or quay below deck level. With a self weight of 2,852 kg and a Ø1,000 mm base plate, it is meant for barges, cargo vessels and quays with a strong, engineered pedestal.

Rated capacity always depends on radius. At 8.51 m the SQ10ZA5TJ lifts 2,280 kg and at 10.56 m it lifts 1,800 kg, so check the weight of your heaviest regular load at the distance you need before you choose a tonnage.

Where the 10 ton SQ10ZA6TJ fits

The SQ10ZA6TJ has the same folded size, reach and base plate as the 8 ton SQ8ZA6TJ but is rated to 10,000 kg. Choose it for barges, cargo vessels and quays where heavier lifts happen at mid radius, such as stores, machinery or construction material. At 2,920 kg it needs a deck structure designed for that weight plus the lifting moment.

Need a longer, straight boom instead? Compare the 10 ton telescopic boom marine crane (SQ10SA4T).

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 SQ10ZA6TJ load chart and the deck space it needs when folded.
