Independent wheel-speed-based braking reduces cornering twist in mobile medical apparatuses while keeping both drive wheels stopping together.
Differential front steering and individually driven rear planetary wheels improve turning, obstacle climbing, and wheel wear on rough terrain.
A spring-assisted pedal linkage deploys a trolley locking pad with low effort, keeping suspended-castor carts stable even under heavy loads.
A torso-worn pulling strap shifts wagon force from the hands to the shoulders and torso, reducing fatigue while improving control on uneven ground.
A three-leg handle support resists unwanted rotation while sensing horizontal displacement for smoother cart translation and turning.
A push member with slanted surfaces retracts opposing rods together, simplifying manual locking while maintaining equal, reliable motion.
Magnetic or mechanical mounting and elastomeric panels protect concrete corners and shopping carts while simplifying replacement.
