SQ3.2SA3T Marine Cranes on Fixed Bases in Myanmar

A yellow telescopic crane on a concrete base beside a water channel in the hills, and an orange crane of the same model on a jetty by open water: four photos from our customer in Myanmar show BOB-LIFT SQ3.2SA3T telescopic marine cranes on fixed bases.

What the photos show

• In the hills. A yellow crane stands on a concrete pad next to a concrete water channel with steel railings. Steep, forest-covered hills rise behind it, and a yellow gantry frame stands nearby.
• The crane. The boom is marked BOB-LIFT and SQ3.2S, with a NO STANDING UNDER THE BOOM warning, and the hook block is painted in yellow and black stripes.
• Just unpacked. Beside the column, the power unit is still wrapped in plastic sheet. Two photos show the same view, and in one a pile of plastic wrapping lies on the ground in front of the crane.
• On a jetty. In the fourth photo an orange crane stands at the edge of a concrete jetty. A white control box with push buttons and an electric motor sit at its foot. Workers in hard hats stand beside it, one reaching up to the hook, and a vessel lies alongside.

These are the customer's own photos. No load weights, dates or comments came with them.

SQ3.2SA3T specifications

The SQ3.2SA3T is a 3.2 t telescopic boom marine crane with a maximum lifting moment of 6.8 t·m and three boom sections. All figures are read from the technical department's dimension and load chart drawings.

Lifting moment is the load times its distance from the slewing centre. That is why the rated load drops as the boom reaches out. For example, the SQ3.2SA3T lifts 3,200 kg at 2.2 m but only 550 kg at 8.3 m. Working radius is the level distance from the slewing centre to the hook. On a vessel or a quay, the pedestal takes the place of outriggers. It must be strong enough for the crane's weight and its full lifting moment. For general crane safety rules, see the OSHA cranes and derricks standard.

Raising the boom brings the hook closer in and the rating up: at 60° with the boom fully extended, the crane is rated for 1,360 kg at 4.15 m.

The SQ3.2SA3T product page has the full drawings, and other models of this size are on the 3.2 t telescopic boom marine crane page. The same model works on aluminium pontoons in our delivery record from Australia, and a 3.2 t telescopic truck crane works in our record from Thailand.

A marine crane on a fixed base ashore

A marine crane also works well on land next to water, where a truck cannot reach. It needs a solid base and its own power. Four points to plan for:

1. Build the base for the moment. The 550 × 550 mm base plate must be anchored into a concrete foundation that can take the full 6.8 t·m moment, not only the 1,050 kg crane weight.
2. Plan the power. With no engine nearby, an electric motor can drive the hydraulic pump. The SQ3.2SA3T needs 25 L/min at 20 MPa, about 14 kW, so check the site supply first.
3. Clear the wrapping before the first start. Remove all plastic from the power unit and the cooler, and check the oil level. Cover the control box again when the crane stands idle.
4. Keep the slewing area clear. Railings and channels limit where people can step back. Mark the swing zone and keep people out from under the boom.

Sea water is hard on steel, so the marine cranes get an epoxy zinc primer with a polyurethane acrylic top coat. Other capacities are in the telescopic boom marine crane range, and the marine crane buying guide covers mounting in more detail.

What to send us for a marine crane

To check a crane like the SQ3.2SA3T for your site, we need a few details. Short answers are fine.

• The site. The vessel type and length, or the quay, and where the crane will stand.
• The lifts. The heaviest load, and how far from the crane it is picked up and set down.
• The power. The hydraulic power pack you have now, or whether you need a new one. The SQ3.2SA3T needs 25 L/min at 20 MPa, about 14 kW.

Send these through the contact page, and our team will check reach and load against the chart.
