ABSTRACT:
An improved design that would allow one workman to easily elevate a heavy concrete tie to the base of the rail and hold it in position while tie is connected to the rail with retainer clips. Improvements are made in the handle design that allow the workman to remain in a more upright position at the time the tie comes in contact with the rail. Also added is a safety grip ring near the upper end of the handle. Design improvements are also made at the foot end of the handle unit. At this point the improved tool design will allow more leverage to be applyed to the tie and a varity of hook devises to be used on lower end of tool, depending on what type of concrete tie is to be used.
