Stone Extreme

Unparalleled. Profile&Polish. Productive.

40 percent faster at start up 600 percent faster to 5,000 square feet. The Stone Extreme is designed to tackle any large scale profile, hone and polish (PHP) project.  Outfitted with 3 heavy-duty, planetary gearboxes driven by hi-flow hydraulic systems common to track-steer equipment, the Stone Extreme is specifically equipped for wet grinding in any environment.  Equipped with a standard quick-change system to promote even abrasive wear and quick field changes cutting downtime on PHP projects.

CONCRETE GRINDING EQUIPMENT

High Performance Stone Extreme

Equipment Description: 

The Stone Extreme is the highest productivity concrete grinder for post-placement concrete surface profiling, coating removal or polishing.  Outfitted with the industry’s oldest and most reliable mining industry inspired, durable, self-contained gear box. The Stone Extreme is the solution to any large concrete surface refinement project as the 77” cutting path makes quick work of any surface: coating removal, coating prep (surface profiling), grind & seal or full PHP (Profile, Hone, Polish).

Capable of completing 8,000 square feet per hour, the Stone Extreme is the solution to advancing any construction or production schedule without the downtime of other equipment systems.  Powered by specific Hi-Flow (40 gpm hydraulic flow required) track-steer equipment enables a single operator and a spotter to complete the work of 6 employees, drastically cutting labor.

The Stone Extreme features a system that will enable even abrasive wear and quick field changes.  

Cut Your Labor

Profile, Hone and Polish concrete at an astounding 8,000 sq.ft. per hour using a crew of 2.

Cut Your Downtime

Diesel powered engines (as well as propane powered equipment) eliminate the need for electricity to facilitate grinding in any environment, in any phase of construction, using fewer employees with unparalleled productivity.

Cut Your Environmental Impact

Cord-free grinding using water leads to improved indoor air quality during construction and after as HVAC ducts will be clean and clear.

Water + Head Pressure + Cutting Edge = Refinement

Cut the Cord!

Cordless Diesel or Propane power eliminates the potential hazard of water meeting electricity. Catalytic mufflers ensure minimal impact on indoor air quality from diesel powered skid-steers. 

Reduce the risk of trip & fall accidents. No danger of running over power cables with equipment.

 

If using Bobcat as the skid-steer powering the Stone Extreme, emissions are reduced drastically and will continue to be reduced as a part of Bobcat’s commitment to environmental responsibility.

Additional Feature: 

The Stone Extreme is designed specifically for wet cut.  The wet process uses water to cool abrasives and eliminate dust.  Water reduces abrasive friction and acts as a lubricant, thereby increasing the life of profiling and honing abrasives. The wet process eliminates airborne crystalline silica dust and its potential health hazards such as silicosis due to inhalation of these dangerous airborne particulates improving IAQ (Indoor Air Quality).

Hidden Issues: Abrasive Cutting with Electric Equipment

 

Eliminate the wait!  Electric powered machines generally require 3-phase power wired by a certified electrician and drawing considerable power from the facility.  Green Umbrella recommends the use of renewable resources such as propane powered, clean-burning EPA & CARB certified engines.  Diesel fuels the Stone Extreme.

 

 

Hidden Cost to Ownership:  Calling upon the facility maintenance team and requesting an electrician establish suitable power is just the start.  Each electric machine will draw substantial kilowatts of energy during the course of the project.

Sample Electric Grinder Motor (40 Amps – 460 Volts) – 31.8 kilowatts x $0.12 cents per kwh = $3.82 per unit per hour.  Average daily operating cost (8 hour day) – $30.53 per machine paid by facility ownership daily.

Sample Project: 5 day project using 2 electric machines will total $305.30 in “hidden cost” to ownership.

 

Equipment that is NOT Designed to Cut Wet:  While Green Umbrella’s fleet of grinders are designed to cut wet, electric grinders are not.  Water + Electricity do not mix!  Eliminate danger and protect workers all without possibly introducing harmful silica dust into the air by using equipment designed for wet profile, hone and polish work.  Propane or Diesel powered machines eliminate the potential hazard of water meeting electricity.  

Expensive Portable Generators and Cords:  Not required when using Green Umbrella grinders.  Construction sites are filled with potential hazards.  Eliminate the potential for a trip and fall by eliminating the use of cords while profiling, honing and polishing. Choose cordless propane or diesel equipment.
