Making the Grade: A Colorado Contractor Uses a German-Made Tool to Remove Manholes Quickly and Speed Up Paving Operations

This article describes the Stehr Manhole Cutter, a German-made manhole cutter that removes manholes from roadways that are being repaired and repaved. Traditionally an inefficient, slow, and labor-intensive process, manhole adjustment involves pummeling the surrounding asphalt, removing the steel casting, and covering the utility. The process on average allows for the removal of up to six manhole castings per day. This article describes how the Stehr manhole cutter works, how it increases productivity, and how it was used in a project in Grand Junction, Colorado where 23 manholes were adjusted in two days.
