ABSTRACT:
A form erection hoist for use with concrete building forms or panels has a support which engages the top or an intermediate rib of an erected form. A column is rigidly attached to the support and extends above and below it. A support for a central and an outboard sheave is mounted on the upper end of the column. A cable reel support is mounted on the lower end of the column and engageable selectively between the sides of an erected form. Cable from the reel extends around the two sheaves and downwardly to engage the handle of a form to be raised into position alongside the previously erected form or to be lowered when no longer needed. The sheave support is shiftable to extend outboard of either side of an erected form. The hoist is lightweight and may be handled and operated by a single person with minimal risk of injury.
