Our largest telescopic marine crane, the SQ20SA5T, went onto the deck of a working vessel in New Zealand. The customer's three photos, taken alongside a wharf, show the crane being lowered onto its pedestal, the slewing base in place, and the boom extended high over the deck.

Installation alongside the wharf
- Lowering onto the pedestal. A second crane lowers the SQ20SA5T on slings onto a raised pedestal on the deck, while fitters in high-visibility clothing wait on the walkway beside it.
- Slewing base in place. The crane's base sits on top of a tall, red-painted pedestal at the side of the deck, with a walkway and handrails running past it. The BOB-LIFT and SQ20S markings are legible on the boom in this photo.
- Boom extended. Another photo shows the telescopic boom extended and raised high above the deck.
- Setting. The vessel lies at a concrete wharf with hills behind the harbour.
The customer sent photos only. No load weights, dates or vessel details were recorded with them.
SQ20SA5T reach and load
The SQ20SA5T tops the BOB-LIFT telescopic boom marine crane range at 20 t and a 50 t·m maximum lifting moment. Reach and load figures are read from the technical department's drawing.
| Item | SQ20SA5T |
|---|---|
| Max. lifting capacity | 20,000 kg at 2.5 m |
| Boom sections | 5 (1 main boom + 4 hydraulic) |
| Max. working radius / height | 22 m / ≈ 24 m |
| Slewing | 360° continuous |
| Crane self weight | 6,950 kg |
| Hydraulic flow / pressure | 80+63 L/min at 25 MPa, 55 kW recommended |
| Radius (m) | 2.5 | 6.3 | 10.3 | 14.3 | 18.3 | 22 |
|---|---|---|---|---|---|---|
| Load (kg) | 20,000 | 12,000 | 6,300 | 3,500 | 2,200 | 1,500 |
At its full 22 m radius the SQ20SA5T is rated for 1,500 kg. Over the side of a vessel, many lifts happen well out from the slewing centre, so that end of the chart matters most.
What the pedestal and the ship have to supply
On a truck, outriggers and the chassis carry the crane. On a vessel, the pedestal and the deck structure do that job, and the ship's hydraulics drive it. For a crane of this class, check:
- Pedestal and deck structure for the 6.95 t self weight plus the overturning moment of a 50 t·m crane. In these photos the pedestal stands well above the deck, and the boom base sits above the handrails.
- Hydraulic supply: 80+63 L/min at 25 MPa, with about 55 kW available from the vessel's power pack.
- Reach over the side: the distance from the slewing centre to where loads are picked and set down on the quay, read against the chart above.
For protection against seawater, the marine cranes have an epoxy zinc primer and a polyurethane acrylic top coat. Specifications and the dimension drawing are on the SQ20SA5T product page. Smaller models are in the telescopic boom marine crane range, and the marine crane buying guide covers deck mounting in more detail.
