  • Patent number: 6488130
    Abstract: An apparatus for the application of a braking force to a wheel of a wheelbarrow, hand cart or other type of a cargo portage device includes a twist grip mechanism with a latching type of a ratchet attached to the handlebar of the device. As the twist grip mechanism is rotated a progressive braking force is applied to the wheel by tightening a brake band that extends around a drum that is attached to the wheel. A cable is attached at one end to the twist grip mechanism and to the brake band at its remaining end. The ratchet maintains the braking force that is applied until a thumb release lever is depressed which disengages a ratchet dog from contact with any of a plurality of ratchet teeth.
