What we engineer on an A-frame rescue boat davit

Take the whole machine or single work packages.

A-frame structure

Legs, cross beam and pivots, checked through the full swing.

Winch and brake

Hoisting winch, brake and the lowering arrangement for a controlled descent.

Stored-energy launching

Accumulator or gravity arrangement so the boat can be launched without power from the ship.

Load cases and test loads

Launching and recovery with heel and trim as the rule set you name defines them, and the arrangement for the proof load test.

Strength, buckling and fatigue

Hand calculation and finite element analysis of the structure, pins and connections, with assumptions and results written so a surveyor can follow them.

Foundation and interface

Bolting or welding to the deck, the loads passed into the ship structure and the interface drawing your yard needs.

What you receive

A package your purchasing, production and certification people can work from.

If you need the davit built as well

Most clients want engineering only. Some want one party responsible until the machine is on the truck. You choose how far we go.

Engineering only

You receive the complete design package and build it in your own works or with your own suppliers.

Engineering with production follow-up

We stay on the project while it is built: supplier questions, drawing revisions, inspection of critical welds and dimensions, factory acceptance test.

Engineering and manufacturing

We have the equipment fabricated, assembled and tested by qualified workshops to our drawings and under our technical supervision, and deliver it to you with its documentation.
