| Dolly apparatus for hauling loads on a pitched surface includes frame structure secured to wheels, with the wheels being adjustable in height so that the dolly may be moved along a pitched surface with the load maintained in a proper horizontal orientation. Different embodiments are disclosed, which embodiments may be used for different types of loads. One embodiment is a relatively simple embodiment which may be used for a relatively light load, and a second embodiment is a relatively complicated embodiment which may be used to transport heavier loads. The second embodiment includes wheels which may be oriented ninety degrees for moving in two directions, for example for moving a load to a specific location in one direction and then moving it in a second direction for specifically positioning the load. | ||||||
| 74 | Brake assembly for pallet lift truck | US296103 | 1981-08-26 | US4424885A | 1984-01-10 | Tuval Kedem |
| In a pallet lift truck having a base, an upright axle shaft, a wheel fork and a transverse axle mounting a pair of spaced resilient wheels, and a normally upright steering handle pivoted at one end to the base. A mechanical brake assembly comprises a brake housing with downwardly opening slots positionable over and removably mounted upon the axle between the wheels. An upright brake arm extends into and is pivotally mounted upon the brake housing and includes a brake bar projecting therefrom overlying and spaced from the wheels and normally biased to an inoperative position. A brake actuator boss upon the steering handle on downward pivoting thereof operatively engages the brake arm moving the brake bar into operative compressive frictional engagement with the wheels. | ||||||
