Product details · SQ3.2SA3T

3.2 Ton Telescopic Boom Marine Crane SQ3.2SA3T

The SQ3.2SA3T is a 3.2 ton telescopic boom marine crane. It lifts 3,200 kg at 2.2 m, 1,900 kg at 3.5 m and 550 kg at its full 8.3 m reach, with a maximum lifting moment of 6.8 t·m and 360° slewing. The crane itself weighs 1,050 kg.

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.

Base plate 550 × 550 mm
Mounting bolt holes 20 × Ø22 mm
Bolt pattern 480 × 480 mm
Centre hole in the base plate Ø220 mm
Crane height, boom stowed 2,000 mm
Hydraulic supply 25 L/min at 20 MPa, about 14 kW
Oil tank 60 L

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.

FAQ

Questions about the SQ3.2SA4T

About the SQ3.2SA4T

What hydraulic supply does the SQ3.2SA4T need?

25 L/min at 20 MPa. We recommend 14 kW of hydraulic power. Send us the vessel's hydraulic data and we confirm the match when we quote.

What warranty and minimum order apply to the SQ3.2SA4T?

The SQ3.2SA4T carries a 12-month warranty, and you can order from 1 unit.

Can the SQ3.2SA4T lift 3.2 tons at full reach?

No. It lifts 3,200 kg at 2.2 m, and the capacity falls with radius to 200 kg at 10.5 m. Check the load chart on this page at your working radius.

What base plate and bolts does the SQ3.2SA4T need on deck?

A 550 × 550 mm base plate with 16 × Ø22 mm holes on a 480 × 480 mm bolt pattern. Your yard designs the pedestal and the deck reinforcement for the crane’s 1,250 kg self weight and 6.8 t·m lifting moment.

What size of boat or barge suits the SQ3.2SA4T?

We size the crane by load and reach, not by vessel length. The SQ3.2SA4T weighs 1,250 kg and needs 25 L/min at 20 MPa from about 14 kW, supplied by the vessel’s hydraulic system or by an electric or diesel power unit we can provide. Your naval architect should confirm deck strength and stability with the crane at its full 10.5 m reach.

Is the SQ3.2SA4T approved by a classification society?

No. Our hydraulic marine cranes for harbours, barges, workboats and inshore vessels are not certified by a classification society. If your vessel or project needs class approval, confirm it with us before you order.

How tall is the SQ3.2SA4T with the boom stowed?

About 2,200 mm from the base plate. With the boom extended it reaches a radius of 10.5 m.

Can the SQ3.2SA3T lift 3.2 tons at full reach?

No. It lifts 3,200 kg at 2.2 m, and the capacity falls with radius to 550 kg at 8.3 m with the boom horizontal. Check the load chart on this page at your working radius.

What base plate and bolts does the SQ3.2SA3T need on deck?

A 550 × 550 mm base plate with 20 × Ø22 mm holes on a 480 × 480 mm bolt pattern. Your yard designs the pedestal and the deck reinforcement for the crane's 1,050 kg self weight and 6.8 t·m lifting moment.

What hydraulic power does the SQ3.2SA3T need?

25 L/min at 20 MPa, about 14 kW, from the vessel's hydraulic power pack or an engine-driven pump. The crane carries a 60 L oil tank.

What warranty comes with the SQ3.2SA3T?

12 months on the whole crane, with common spare parts dispatched within 48 hours.

How far can the SQ3.2SA3T reach, and how far does it slew?

With every section extended it works out to 8.3 m and still holds 550 kg there, and the column turns through 360°. Place the crane on deck so that your heaviest regular load sits inside the radius the chart allows.

Ordering and service

Which configuration should we choose for this model?

Send the load, the outreach you need over the ship's side, the vessel type and where the crane will stand on deck. Our engineers confirm a practical model and mounting before quotation.

How is the crane mounted on the vessel?

The crane stands on its base plate, fixed to the deck or to a raised pedestal, and the base plate size is on the product drawing. Send us the deck structure at the crane position: we adapt the mounting to your vessel and confirm it with you.

Does this crane suit our sea conditions?

Tell us where the vessel works, whether you lift in port or at sea, and the conditions you expect during lifting. Our engineers check them against the load chart and confirm whether this model suits the job before quotation.

How is the crane protected against corrosion?

Tell us whether the vessel works in salt water or fresh water and where the crane sits on deck. We confirm the paint and surface protection for your conditions in writing with the quotation.

What is the delivery time, and which documents come with the order?

Lead time depends on the configuration, order quantity and destination, and we confirm it in writing with your quotation. Each order ships with a commercial invoice, packing list and bill of lading, plus the product documents required for the confirmed order.

Do you help with installation and after-sales service?

Your shipyard fits the crane with our installation guidance and remote technical support. Cranes carry a 12-month warranty, we reply to service requests within 12 hours, and common spare parts ship within 48 hours.
