  • Patent number: 7112028
    Abstract: A lift dolly is provided for lifting and transporting stand-mounted power tools and the like, with little effort. The dolly includes a pair of platforms and a wheel system having at least three castors extending downwardly from the platforms. The dolly is designed such that one step onto a latching or locking mechanism by the operator causes the wheel system to be forced downward relative to the stand thereby slightly lifting the power tool and stand off of the ground and enabling transport of same via the castors. Another step on the locking or latching mechanism disengages the wheel system and permits gravity to return the stand and tool firmly to the ground for use.

  • Patent number: 5876173
    Abstract: A lift dolly is comprised of a first castor-based platform and a second castor-based platform. Each platform is secured to an object to be lifted such that when so secured, the first platform extends diagonally upwardly and the second platform extends diagonally upwardly and terminates below the first platform. Downward articulation of the first platform causes lever lifting of its end of the object and also engages and causes downward articulation of the second platform which lever lifts its end of the object. Through continued lifting the lever fulcrum moves toward center increasing the mechanical advantage of the device.
