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.
Claims14
A dolly for selectively lifting and transporting a power tool mounted on a stand, the dolly comprising:
- a first platform including a wheel system extending downwardly therefrom, said first platform further including an actuation surface or member for receiving downwardly applied pressure in order to lift the stand and tool off of the ground;
- a second platform including a wheel system extending downwardly therefrom;
- said first platform adapted to be rigidly affixed to one portion of the stand, and said second platform adapted to be rigidly affixed to another portion of the stand;
- said actuation surface or member of said first platform is being located above at least a portion of said second platform;
- lift means for moving the dolly from a passive position to a lift position thereby lifting the stand and power tool off of the ground and enabling the power tool to be moved on the ground via said wheel systems, said lift means including a selectively actuated means for selectively coupling said first and second platforms to one another, and being actuated in response to downwardly applied pressure being applied to said actuation surface or member that forces wheels of said wheel systems downward so that said wheel systems, as opposed to the stand, support the power tool on the ground;
- and
- wherein said first platform includes first, second and third elongated members, and said second platform includes first, second, and third elongated members, and wherein at least a portion of said second and third elongated members of said first platform is located at an elevation higher than at least one of said first, second and third elongated members of said second platform when the wheel systems are supporting the power tool.
A lift dolly adapted to lift and enable transport of an object, the lift dolly comprising:
- a first rigid platform adapted to be rigidly affixed to one part of the object, said first platform including first and second elongated members;
- a second rigid platform adapted to be rigidly affixed to another portion of the object, said second platform including first and second elongated members;
- said first platform selectively coupleable to said second platform;
- said first and second platforms operatively associated with one another so as to enable the object to be lifted off of the ground by applying downward pressure to said first platform which causes coupling of said first and second platforms;
- said first and second platforms operatively associated with one another so as to enable lowering of the object to the ground by applying additional downward pressure to said first platform which causes decoupling of said first and second platforms;
- said first and second elongated members of said first platform located in part directly above first and second wheels connected to said first platform, respectively.
