What we engineer on an SPMT

Take the whole machine or single work packages.

Platform and main beam

Main beam, cross members and the coupling points for side-by-side and end-to-end combination.

Axle and suspension

Pendulum axles, suspension cylinders and their grouping into hydraulic support circuits.

Steering geometry

Steering linkage or actuator arrangement and the angle tables for each steering mode.

Load and stability

Axle load distribution, ground pressure and stability for a given cargo.

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.

What you receive

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.
