  • Patent number: 6253898
    Abstract: An equipment loading plank that is detachably mounted on a machine tool table and used for easy and safe installation and removal of equipment on and off the machine tool work tables. The equipment loading plank includes a flat rectangular shaped body with an upper loading surface and a lower seating surface and a leg downwardly extending at an angle from one end of said loading plank. The leg is inserted into a T-slot in the machine tool table to detachably mount the loading plank to the machine tool table. The leg has a front face and a lower face that converge such that the leg can be wedged into the T-slot when the loading plank is seated on the machine tool table parallel to the upper surface of the machine tool table. The leg ends in a foot that prevents the leg from slipping from the T-slot whenever loads are placed on the loading plank.
