초록

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 tha...
