Herrenknecht is a German provider of technical solutions in mechanized tunneling.

Herrenknecht supplied 3 TBM’s (Tunnel Boring Machines) for the excavation of tunnel No. 1 (section B) and tunnel No. 3 (section C) of the Tel Aviv-Jerusalem fast train (A1 train).

The Herrenknecht TBM’s were costume made for the specific type of land in which the tunnels are located. Thus,  the company is well aware that their  machines are used for mining in occupied Palestinian land.

The TBM is a massive scale machine used to excavate tunnels. The machine operates as an independent work unit, which includes a control room inside the machine.

The machines were made in Germany by Herrenknecht, which is also the manufacturer of the concrete segment’s factory equipment for tunnel lining. The concrete segments for tunnel lining are produced with the help of a carousel plant supplied by Herrenknecht Formwork.

The company also supplied a curing tunnel with heating system. At the end of the work, the machines can be sold back to Herrenknecht, which renovates  and re-sales it to other large-scale projects.

In addition, the company’s fully owned subsidiary H+E Logistic provided a conveyor belt system for the transportation of excavated material during the construction of tunnel No. 3 for the A1 train.
