Mr. Manhole Cutters & Speedplates in Michigan

Pick by cutting diameter, cutting depth, and how often the cutter will run:

B-52: four arms and a fixed 50" diameter with 14" cutting depth. The lightest cutter at 900 lbs., built for crews with standard-size repairs.

Gold Series Six Shooter: six arms, 44" to 60" diameter, and 14" depth for crews that need adjustable cut sizes.

Severe Duty Six Shooter: 44" to 60" diameter with a deeper 19" cut and an extra extended guide shaft for deep frames and thick pavement.

Platinum Series Six Shooter: the widest range at 50" to 72" with 19" depth, plus a spare parts repair kit for common onsite wear items.

In asphalt, plan on about one minute per inch of cutting depth, which works out to 8 to 12 minutes for a typical manhole. Concrete runs closer to a minute and a half per inch. Very hard concrete and some aggregates take longer.

A five-person crew with a little experience can typically remove and rebuild 10 to 15 manhole chimneys in an eight-hour day. One operator cuts and pulls frames while two crew members clean out excavations and two handle the rebuilds.

You need a loader with at least 20 gpm of auxiliary hydraulic flow (30 gpm high flow is a plus), 3,000 to 4,500 psi, 2,500 lbs or more of lift capacity, 75 to 95 HP or more, a universal attachment plate, flat-face couplers, and an enclosed cab.

A compact track loader is the preferred carrier because tracks are more stable and lift more. Carleton Equipment can match a Bobcat loader to your cutter.

Yes, with the right technique. Ease off the down pressure when the teeth reach steel so the cutter shaves the rebar away a layer at a time. Concrete cuts faster than steel, so pushing at normal pressure makes the teeth hit the side of the bar and damages the carbide.

Teeth typically last 100 to 150 cuts in medium asphalt and 75 to 100 cuts in limestone-based concrete. River rock concrete and concrete with reinforcing steel wear teeth much faster. The quick change teeth gun included with every cutter makes replacement fast.

The chimney, between the frame and the cone of the manhole, is where about 90% of manhole leakage happens. Groundwater that leaks in becomes sewage the treatment plant has to pay to process. A rebuilt, sealed chimney stops that inflow and infiltration, and a frame set level with the road removes the bump that damages vehicles and snowplows.

Mr. Manhole designed the Mr. Mister misting system to help crews meet OSHA's crystalline silica standard. It bolts to the drive motor and blankets the cutter in a water mist that knocks silica dust out of the air during the cut.

Manhole repair refers to the process of fixing or maintaining a manhole to ensure it remains operational, safe, and structurally sound. This can include replacing manhole covers, sealing cracks, adjusting height or alignment, and restoring damaged concrete.

With Mr. Manhole's cutting tools, this process can be drastically expedited. Our circular cutting and manhole lifting equipment can make lid removal and replacement seamless, leaving you to continue your project without the risky, time-consuming, and backbreaking manual labor.

The cost of manhole removal depends on numerous factors such as accessibility, cutting depth, surrounding infrastructure, and other conditions affecting your work site.

Mr. Manhole's Platinum Series Six Shooter is designed to be cost-effective. With circular cutting technology, you can expect less material waste and reduced labor costs. Faster cutting power and wider cutting diameter help you move through demanding operations quickly while drastically reducing safety risks.

The time it takes depends on the extent of repairs, condition of the manhole, site accessibility, and other factors.

With Mr. Manhole's equipment, repairs can be completed much faster with no safety risks. By using a skid steer-mounted circular cutting tool, full repairs can take anywhere from 10 minutes to an hour depending on complexity — efficiency that traditional methods simply can't match.

Manhole problems typically come from wear, traffic intensity, weather, or age. Common issues include concrete cracking, damaged frames or covers, corrosion, water infiltration, and misalignment — all of which can take considerable time and effort to solve.

Our manhole tools are designed to quickly get manhole lids out of the way during rehabilitation projects, with equipment built for improved safety, better cost-efficiency, and smooth operations.

Mr. Manhole delivers next-gen manhole cutting tools that surpass traditional methods in efficiency, cost-saving, and safety. With up to five times faster turnaround, 20% less debris, and a streamlined user experience, it's the top choice for teams looking to boost productivity.
