Tigercat T726G street trencher

T726G Street Trencher

The Tigercat T726G street trencher is specially designed to cut asphalt and steel-reinforced concrete road surfaces. The attachment trenches below grade, pulverizing the material and backfilling in one pass. The T726G trencher is the first stage machine for utility line installation for gas distribution and water distribution utilities.

Access under-road utilities quickly and efficiently with the Tigercat T726G utility trencher.

With a single machine and one operator, the Tigercat T726G street trencher combines several distinct operations into a single step. As the pavement is cut, the drum simultaneously trenches below grade and crushes the surface material into a mixture suitable for backfill. The T726G is proving to be a key machine for utility construction contractors.

No disposal costs

All costs associated with hauling and disposing of large chunks asphalt or concrete are eliminated, along with dump trucks and excavators on site.

No backfill required

Because the machine backfills the trench as it cuts, traffic is able to cross the job site sooner and without the need for additional materials such as steel plating. No additional backfill is required.

Tigercat build quality

Street trenching is a demanding, high duty cycle application. The Tigercat carrier is specially designed to handle the task — with the required power for high productivity and the durability to withstand the associated forces and vibration.

Tigercat power. Tigercat support.

The T726G street trencher is Tier 4f powered. Tier 4f conforms to the latest emissions standards in North America and Europe. Best of all, Tigercat FPT engines are fully supported by Tigercat and the Tigercat dealer network.
