On a manual site, a stillage a few millimetres out of position is a stillage a few millimetres out of position. On an automated one it is a failed pick, a fault code and a stopped loop. The vehicle approaches the same way every time and expects the same geometry every time, so the handling feature — lift slot, roller face, tow pin, indexing point — is the part of the specification that matters most.
We work from the handling interface your fleet defines: pick height, lift travel, clearance envelope, and the datum the vehicle locates against. That drives the frame design rather than the other way round. Where a robot lifts a cart from underneath, ground clearance and castor position become as critical as the load deck itself.
A frame that holds its geometry on day one but distorts after a year of cycles is the same failure arriving later. Section sizes and joint design are chosen so the unit stays within tolerance under repeated automated handling, not just under a single static load at first inspection.
