A wire activated rim brake system for a rollator partly positioned inside a rollator frame is disclosed. The system compromises a brake housing positioned close to a wheel of the rollator and inside the rollator frame, wherein the housing compromises an entry opening and sliding surfaces oriented at a right angle to the rotational axis of the wheel. The system further compromises a brake assembly to be positioned in the housing compromising a sliding section adapted to the slide along the sliding surfaces inside the housing and a brake section extending at a right angle from the sliding section and protruding through the entry opening. The system also comprises a brake path on the inner rim of the rollator wheel which is parallel with the rotational axis of the wheel.

A stationary platform for supporting a supply transport device is provided. The stationary platform includes a frame having at least two longitudinal sides, a first end and a second opposing end, and a top surface and a bottom surface, and a plurality of legs extending from the bottom surface of the frame to support the supply transport device on the frame. The supply transport device is slidably received on the top surface of the frame. A wheel base assembly having a cleaning device for contacting a bottom surface of the supply transport device, to remove dirt and debris from or to disinfect the supply transport device, is also provided.

An improved cargo dolly for transporting cargo is described having a mobile dolly frame, a main shaft on the frame, a lever proximate to a first part of the frame (where the lever is movable relative to the frame and in responsive communication with the main shaft), a first set of transfer sprockets mounted to the main shaft, a secondary shaft rotatably disposed at a second part of the frame (where the first part is remote from the second part), a second set of transfer sprockets mounted to the secondary shaft, a chain disposed about the first set of transfer sprockets and the second set of transfer sprockets, and a locking pin having a first end fixed to the secondary shaft and a second end configured as an angled latch. Rotation of the lever responsively causes the locking pin to remotely rotate at the second part of the frame.

An improved auto-chocking enabled cargo dolly that is towable by ground support equipment. The dolly has a frame, wheels attached to the frame that support the frame and rotate to allow movement of the frame, a tow bar, a linkage in communication with the tow bar and that actuates when the tow bar is raised, and a wheel engagement chocking system fixed to the dolly frame and disposed to selectively engage at least one of the wheels attached to the dolly frame. The wheel engagement system is responsive to a position of the linkage, where the wheel engagement chocking system applies pressure directly to at least one of the wheels to hold the wheel(s) in place when the linkage is actuated by the tow bar.

An autonomous luggage cart system and method for transportation of objects in facilities such as hotels, condos, universities, and convention centers, providing a cart having a floor, a bumper, riser pipes, and an underside housing, wheels driven by electric motors, a high-capacity battery and a battery charge manager, front and rear tow hitches and tow-hitch sensors, corner sensors, a camera-sensor package, directional sensors, RFID units, a controller unit applying machine learning and artificial-intelligence methods to sensor data, and a communications unit and a remote unit for external communications with other systems.

A wheelbarrow braking assembly for slowing or stopping a wheelbarrow includes a brake rotor that is attachable to a wheel of a wheelbarrow. A caliper is mountable to the wheelbarrow such that the caliper is aligned with the brake rotor for slowing or stopping the wheelbarrow. A brake handle is provided that is mountable adjacent to an end of a respective rail of the wheelbarrow. In this way the brake handle is accessible to the user when the user is maneuvering the wheelbarrow. The brake handle is in mechanical communication with the caliper and the caliper is engaged when the brake handle is squeezed.

Systems and methods for transporting objects using a cart that is driven by human action or self-driving vehicle is disclosed. The cart system and method comprises a chassis portion supporting a payload to be moved by the cart. The cart system further comprises of a first side rail and a second side rail. A first front wheel and first rear wheel is attached to the first side rail and a second front wheel and second rear wheel is attached to the second rail. The handle portion pushes the cart which comprises of a handle bar supported by vertical support members. The brake actuator is used to engage and release the brakes on the rear wheel. A horizontal engagement bar is used which comprises of a plurality of engagement pads. A payload-bearing surface bears payload such that the payload can be transported by the cart.
