Drives for Tunnel Boring Machines tunnel

This considerably widens the range of application of the drive and thus of the entire tunnel boring machine. The gear is changed hydraulically when no load is applied. The three gear positions, first second and neutral, are monitored by sensors. The two gear

Gearboxes for Industrial Equipment ZF

Tunnel boring machines up to 19 metres diameter and 32 tonnes applied pressure per cutting roller are only one example of many applications in the industrial field where ZF transmissions are employed. Here enormous forces are involved which signify huge challenges for personnel and machines.

Tunnel Boring Machines IMIA

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 t he possibility of creating tunnels where it was not feasible before.

Tunnel boring machine solutions from SKF

During tunnel boring machine development projects, break downs can be equally damaging. A main bearing failure can stop a project for as long as two years, negatively impacting the manufacturer’s bottom line and quite possibly, customer relationships. Clearly, tunnel boring machines require the most reliable components and systems available.

Bertha (tunnel boring machine) Wikipedia

Bertha was designed and manufactured by Hitachi Zosen Sakai Works of Osaka, Japan, and is the world's largest earth pressure balance tunnel boring machine, at a cutterhead diameter of 57.5 feet (17.5 m) across. The machine was 326 feet (99 m) long and weighed 6,700 short tons (6,100 t). The machine itself cost $80 million and is owned by Seattle Tunnel Partners, the project contractors.

Tunnel boring machine Wikipedia

A tunnel boring machine (TBM), also known as a "mole", is a machine used to excavate tunnels with a circular cross section through a variety of soil and rock strata.They may also be used for microtunneling.They can be designed to bore through anything from hard rock to sand.Tunnel diameters can range from one metre (3.3 ft) (done with micro-TBMs) to 17.6 metres (58 ft) to date.

How Does a Tunnel Boring Machine (TBM) Work? Tunnel

The trailing gear includes a conveyor belt that removes all the soil excavated by the cutterhead from the tunnel, which gets longer and longer as the TBM makes progress. The trailing gear also holds supplies that the operating crew needs to keep the machine moving forward. Sometimes, up to 25 crew members at a time can be needed to operate a TBM.
