ABSTRACT:
A mechanical assembly for pulling the form work away from a concrete structure after the concrete structure has cured. The form work is typically wood or steel and requires a large mechanically force to free it from the concrete structure. The form puller assembly includes a lever assembly, a fulcrum assembly, and a form pulling assembly. The user pulls down on the opposite end of the lever assembly generating a mechanical force sufficient to free the form work from the concrete structure. Also, the mechanical assembly may include at least one embedded element extracting assembly for removing vertically oriented elements embedded in the soil and/or concrete.
