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...
1. A twist-grip brake for a cargo portage device, comprising:(a) a member adapted for attachment to a handlebar of said cargo portage device, said member adapted for rotation in an arc about a longitudinal axis of said handlebar, said arc extending for a predetermined distance; (b) means for applying a braking force to a wheel of said cargo portage device; and (c) means for actuating said means for applying a braking force, whereby said means for actuating is adapted to urge said means for applying a braking force subsequent to said member being rotated ...
