ABSTRACT:
There is disclosed a hoist for lifting a fire hydrant from its underlying upright feeding pipe. The hoist comprises an inverted L-shaped post with a manually-operated cable winch. The post is supported on a semi-circular base collar which fits the top coupling flange of the feeding pipe. This collar has top and bottom inwardly extending flanges for embracing the above-noted coupling flange. A toggle lever clamp locks the collar in position. The collar has a lateral extension on which the post is mounted to clear the fire hydrant. The post can be rotated to swing the fire hydrant laterally of the feeding pipe to facilitate access to the interior of the same. A latching mechanism latches the post in any of a plurality of rotated positions.
