Abstract: Hand truck or dolly apparatus includes a main frame and a pair of main tires and brake elements secured to the main frame, including a pair of plates movable against the tires. The brake plates are actuable either by a foot operation or by hand operation. The brake plates may be set only by foot operation, while the hand operation of the brakes moves the brake plates against the wheels for a "feathering" brake action. The dolly apparatus also includes a pair of rear stabilizer wheels disposed on a frame pivotally secured to the main frame of the dolly or hand truck. The stabilizer wheels are movable between a down and use position and an up and storage position.

Abstract: 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.
