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.
