Abstract

Abstract An auto body and frame puller which includes a generally horizontal box girder base member supported on casters for moving from place to place. An upright post is supported from the base member and has a plurality of vertically spaced eyes for attachment of one block of a block and fall. A winch on the base member is provided for winding in the block and fall cable under power. A hook is provided on a second block of the block and fall for attachment to a portion of the frame to be straightened and a second hook on the outer end of the base member has a chain attached thereto for connection to the opposite side of the frame to be straightened. Operation of the winch causes the second block to move toward the post to pull on the portion of the frame to be straightened. The first block can be hooked into anyone of the eyes on the post to vary the direction of the pull with respect to the horizontal.
