As already mentioned, it is advisable to have a trencher at hand in civil engineering. But why is that so? Many people ask themselves this question, especially if an excavator is also often available in the yard. But many unfortunately underestimate the efficiency of the trencher, especially when it comes to laying cables.

Probably the most decisive difference lies in the working time. On average, a trencher can cover three times the distance of an excavator in one day. This means that you would need three excavators to cover the same distance per hour as a trencher.

Furthermore, trenchers manage to dig a cleaner and, above all, more robust trench than excavators can. This is because the chain of the trencher literally “cuts” a trench. So there is less vibration in the earth, which in turn makes for a more stable trench.

Another point is the facility with which the cables can be laid after trenching. We like to call this “all in one”. What we mean by this is very simple. It is possible to equip the trencher with attachments so that trenching, laying and compacting can be done in one step. After the trencher has dug the trench, the desired cables can be inserted directly into the ground through a laying shaft, without having to employ an employee. Afterwards, the excavated material deposited on the sides can simply be thrown back into the trench and the cable is laid.

This not only saves time, but also costs, as fewer employees are needed on a construction site.
