Side-surface projections and lever claws lock the caster roller without tread friction, improving braking durability and release.

Active pull-rod steering and modular frame joints make the camping cart easier to assemble, maintain, and steer on soft ground.

Fixed front wheels and omni-directional rear wheels reduce steering resistance, enabling fine direction adjustment under heavy loads.

A handle-linked castor brake uses edge friction and automatic engagement to lock swivel wheels in any orientation and prevent rollaway.

A hydraulic cylinder and switchable valve keep industrial truck drive wheel load stable, preserving traction and lateral stability on uneven ground.

A handle-driven linkage folds and deploys flatbed truck casters to cut storage space while preserving flexible pushing and dragging modes.

A geared offset drive wheel matches wheel and pivot speeds to preserve ground clearance while improving steering control and drive efficiency.

Rectangular caster recesses and self-centring wheel biasing keep stacked dollies aligned, stable, and protected during transport.

A support wheel protruding through the vehicle frame increases counter-torque to prevent backward tilting without added weights.

Sacrificial shear plates in a portable lift caster break above 2000 pounds to stop unsafe transport and allow simple replacement.

An elastic L-shaped buffer between wheel and body fixings absorbs obstacle shocks, limiting vibration and posture disturbance in medical equipment.

Moves under existing holders, lifts them, and changes travel direction by wheel rotation instead of body rotation to reduce transfer damage.

A modular cart with adjustable supports, brakes, and a tow hitch makes heavy EV battery removal, transport, and maintenance safer and faster.

A segmented handle with force sensing lets an omnidirectional cart move sideways intuitively while protecting sensors from excessive load.

An X-shaped wheel frame and adjustable omni wheels let the cart fold compactly while preserving flexible operation across different environments.

Curved side beams and pallet foot guides enable automatic rotation, alignment, and fixation during short-distance autonomous loading.

An L-shaped elastic buffer in the caster absorbs obstacle impacts, limits vibration transfer, and helps keep medical equipment stable.

Sensors, drive units, and onboard computing let a service cart self-navigate, avoid obstacles, and deliver goods with less manual labor.

Claws lock into side-face projections instead of the tread, giving caster braking without roller surface damage and with durable engagement.

A connectable wheel linkage and rear brake constrain three omnidirectional wheels for smooth straight travel while preserving free rotation.

Independent non-drive wheels and a swingable rear wheel unit help a powered handcart clear bumps while keeping drive wheels grounded for traction.
