Abstract
A manhole adjustment ring removal assembly includes a frame. A pair of legs is pivotally coupled to the frame. Each of the legs has an upper end and a lower end and each end has one of a pair of the plates attached thereto. The plates each have an outer edge extending outwardly away from a corresponding one of the legs. The outer edges taper to point and are extendable between an adjustment ring and a cone base. A drive assembly is mounted on the frame and is mechanically coupled to the legs. The drive assembly is actuated in a first direction moving the lower ends away from each other and in a second direction moving the lower ends toward each other. A lift ring is attached to the frame to be engaged with a cable to lift the frame when the plates are positioned under the adjustment ring.
