What we engineer on a straddle carrier

Take the whole machine or single work packages.

Portal frame

Legs, top frame and wheel beams, checked for travelling with the load raised.

Lifting gear

Hoist cylinders or winches, with spreader or sling beams for your load.

Wheels, steering and drive

Wheel loads, steering geometry and hydrostatic drive, with the ground loads for your yard surface.

Load cases

Operating, test and stowed conditions defined with the dynamic factors of the rule set you name.

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

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

FEA reportStrength, buckling and fatigue, with load cases stated

Hydraulic schematicCircuit diagram, component list, sizing

Technical documentationSpecification, manuals, technical file content

Engineering animationOperating sequence for tenders and design reviews

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.
