Cart Push Force Calculator

Estimate the sustained force needed to push a loaded cart from its weight, rolling resistance, and floor grade, and compare it with the 50...

Caster Motion & Ergonomics

Work out whether a brake holds a loaded cart on a slope, whether you need a wheel brake or a total lock that also...

Caster Motion & Ergonomics

Work out how much of an operator's strength budget a cart's push effort consumes and how long that effort can be sustained, so the...

Caster Motion & Ergonomics

Work out whether a caster rolls over a threshold, dock plate, or floor joint, the push force it takes, and whether the wheel locks...

Caster Motion & Ergonomics

Work out the trail and lead of a swivel caster, and judge whether it will self-centre, wander, or pivot under an offset or high...

Caster Motion & Ergonomics
