  • Patent number: 5257892
    Abstract: A pipe machine dolly/cart combination is designed with spaced-apart wheels at both ends of a load carrying platform. Removable handles are provided to permit the dolly/cart combination to be manipulated from both ends to be rolled about on a surface, and to be pivoted about the wheels on either end. With the handles attached to one end, the dolly/cart may be manipulated by a single person to permit the loading and unloading of the cart to and from a raised surface, such as the bed of a truck. When the removable handles are secured to the other end, the device may be used as a dolly to transport the load, and to deposit the load on a surface when the device is pivoted 90.degree. . The device is ideally suited for facilitating the loading and unloading and transportation, by a single person, of a relatively heavy load, such as a pipe threading machine, or the like.
