The tunnel boring machine is a machine which has been developed in recent years and has revolutionised the tunnelling industry both making tunnelling a safer, more economic solution for creating underground space and opening the possibility of creating tunnels where it was not feasible before.

For 12 years Kohinoor Hydraulic Pumps has been experts in repairing, remanufacturing, fabricating, modifying and recertifying hydraulic Solutions for Tunnel Boring Machine.

You can find hydraulic motors powering a number of different functions in tunnel boring machines including:

• The cutting drive that rotates the cutting shield
• The screw conveyor that extracts the soil from the machine
• The erector rotation drive that positions the tunnel lining segments

Beyond these applications, Hydraulic pumps are a viable solution for the thrust cylinders, which power the machine forward.
