In Depth – Tracked Trenchers

Tracked Trenchers are the best solution for medium and big projects when the contractor wants to save money and meanwhile wants to achieve the highest productivity.

If you want to choose a tracked trencher for your next project there are 2 main variables to be kept in mind:

  • The dimension of the trench
  • Soil

The combination of these two variables is the key factor to be taken into account when choosing a trencher. For medium-sized projects (involving 150 cm depth and 20 cm width) there are really a lot of choices in terms of models and manufacturers and the main variable, in this case, is the kind of soil you will have to dig: the harder it is the more powerful the trencher has to be.

In this field, the best manufacturers on the market are Vermeer and Tesmec. Both of these companies have designed the best machines available, from the smallest T455 series of Vermeer to the very big Tesmec TRS1475.

Differences among models are in terms of gross horsepower, length of the boom and various optional equipped on them.

In terms of Horsepower we can make this distinction, taking as an example some high-selling tracked trenchers:

In order to achieve the highest productivity, there are also some optional tools installed on the trencher. These can give further maneuverability during the execution of the work.

The main optional we can find in most tracked trenchers are:

Tilt: the auto-leveling system that keeps the tractor and the trencher boom perpendicular to the trench, in order to perform a perfect cut even with 10° slopes. Tilt is generally found in small and medium-size trenchers.

Elevating cab:  the cabin can be elevated to make sure that the operator has the best vision of the work.

Offset: if a trencher has the offset there is the chance to move the boom in horizontal (from the center to the left or to the right) and perform cuts alongside a wall or a road. You can know if a trencher has the offset by directly looking at its name. For Vermeer models, the “8” final indicates an offset trencher (T558, T658, T758), while for Tesmec Trenchers there is the “SLO” acronym (Sliding Offset) TRS950 SLO, TRS785 SLO.

Loading conveyor: if you want to put the removed material directly on a truck and not to the sides of the trench, the loading conveyor gives you this chance. Since the excavated material is ready for the backfill then there are not chunks of rocks and a loading conveyor can put everything apart.

Reel carrier: If the job requires to lay cables you can attach a reel carrier to the trencher and perform the job in just one pass. Cut+lay
