<p>BRAKE MECHANISM FOR A HAND OPERATED LIFT TRUCK A brake mechanism for hand operated lift trucks in which two brake shoes are pivotally mounted on the lower end of the handle assembly so that contact between one or the other shoe and the brake drum is accomplished by either upward or downward movement of the handle. The pivotal mounting of the shoes makes them self adjusting. A spring is used to return the handle to a brake applied position when the handle is released by the operator.</p> |
