Hard Rock Trenching

Tesmec Chain Trenchers

Trenching Systems Australia's fleet includes 3 Tesmec trenchers. The Largest of their type in Western Australia, these machines are purpose built in the USA and designed for extreme soil and rock conditions. The cutting chain uses tungsten carbide tipped digging teeth to " grind " the ground as it moves along . The action of cutting excavates the soil, or spoils, from the trench at the same time, bringing it up to the top of the digging face where it is dropped on to a conveyor. The conveyer can be moved to the left or right and discharges the ' spoils ' into rows at a predetermined distance from the trench. As the rows are set away from the trench edge, access by machinery and personnel is less restricted and allows for a better working environment .

TESMEC TRS 1300 Trencher
This machine is capable of digging a trench 1100mm wide by 2400mm deep. Powered by a 500HP Caterpillar 8 cylinder diesel engine, the TRS1300 is the largest machine in the fleet. Mobilised on large tracks and weighing around 75 tonne, this trencher is set up for the hardest of soils and the larger type projects.

TESMEC TRS 1200 Trencher
This machine is capable of digging a trench 800-950mm wide by 2400mm deep. Powered by a 480HP Caterpillar 6 cylinder diesel engine, the TRS1200 is the same physical size as the larger machine but with less Horsepower. Also mobilised on large tracks, the TRS 1200 weighs in around 68 tonne but is also set up for the hardest of soils and the larger type projects.

TESMEC TRS 1000 Trencher
This machine is capable of digging a trench 700mm wide by 2100mm deep. Powered by a 350HP Caterpillar 6 cylinder diesel engine, the TRS1000 is smaller in size and is typically used for smaller projects such as subdivisions and lateral pipework where a narrower trench is all that is required. The TRS1000 runs on lugged tracks and weighs in around 35 tonne.
