How we engineer
Four principles we design by.
01
Right first time
We correlate models to test data, then iterate virtually so the design passes its standard before parts are made.
Ceiling-fan CFD: 90+% correlation with physical tests02
Lighter, with proof
We take weight out only where the analysis shows the safety margin stays intact.
Motor housing: up to 10% lighter with a similar factor of safety03
Simpler beats added parts
We look for geometry and layout changes before adding mechanisms, mass or parts.
Crane stability solved with an articulated-joint design, not added counterweight04
Designed for total cost of ownership
We weigh installation, operation and service effort, not just part cost.
Stacker reclaimer: commissioning work time reduced by two thirds
