Keep it Clean
Much Less Water Used
Carbide bits cut and break the pavement at a relatively slow drum speed, especially in comparison to a large road saw blade.
The Tigercat 726G Street Trencher carries an onboard water source for use when there is a possibility of a dust condition. In many situations, water is not needed. Since some of the base material is mixed in with the cut and crushed pavement, very little dust is created. With hard concrete or thick asphalt pavement, the use of water for dust control or cooling of the bits may be added. The water system adds water at the drum for dust control and cooling the cutting bits. The water added is completely contained in the cutting area, mixed in with the cut material and therefore never even contacts the road. There is no resulting slurry. This eliminates the necessity of cleaning slurry from the road surface and anywhere else the public may track it.
Cutting at 32 Degrees and Below
No problem. When temperatures drop below freezing, this cutting operation does not create the hazardous condition that may occur with conventional saw cutting. Since there is no cutting slurry on the pavement surface that could freeze, there is no need for ice control to prevent potential slip and fall conditions. Since water only needs to be added for dust control and never contacts the road surface, utility trench cutting can be done at any temperature with little or no dust impact. Naturally, the amount of dust will vary, depending on job site conditions. Spraying the coolant directly into the cutter head and mixing the water with the crushed material eliminates the muddy conditions frequently associated with conventional saw cutting methods.
