ABSTRACT:
There is disclosed herein a pulling apparatus comprising a pair of spaced vertical members each of which is supported upon a base member by a pair of depending diverging support members of unequal length which operate to rigidly support the vertical members against the forces exerted thereon during the pulling operation. An additional vertically extending support member also extends from one of the depending support members to further increase the rigidity thereof. The vertical members may each be provided with opposed channels within which a pulley is movably disposed, said pulley being adjustably supported by a chain or the like engaging a load holding assembly provided upon the upper portion of the vertical members.
