What we engineer on a rough terrain crane

Take the whole machine or single work packages.

Telescopic boom sections

Box sections, overlap lengths, slide pads and the extension system, sized for bending and local plate buckling.

Carrier frame and outriggers

Chassis frame, outrigger beams and pads, with the ground loads.

Slewing superstructure

Turntable, slewing bearing and counterweight.

Load chart and stability

Rated capacity over radius, on outriggers and on tyres, with the tipping and the structural limits.

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.

Hydraulic system

Cylinders, motors, power unit and valve sizing, with the circuit diagram and component list.

If you need the machine 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.
