Drive Technology for Tunnel Construction
Tunnel construction is driven by major projects with tight time frames. Hence, it is crucial for processes to run reliably with no unplanned downtime. This is where RUD‘s drive technology comes into play. The high-performance round steel chain as the basis of the system runs reliably and safely even in a challenging environment: dust, mud, stone or debris cannot damage it.

Space-Saving Drive
The second challenge is the relatively limited space available for tunnel construction work.individual components and the drive housing of the RUD Tecdos drive are compact and can be installed directly on site. “Cable
drives in particular often require a large cable winch with several deflections. This is no longer necessary with our Tecdos drive systems, as the chain can be deflected in a small space and stored in a chain bag that takes up very little space,” explains Sascha Olfert, Business Development Manager at RUD.

RUD Tecdos drive technology offers various products and systems for tunnel construction: from sprockets, lift limiters and slings to complete systems such as Tecdos Pi-Gamma and Tecdos Omega Drive for different requirements in tunnel construction. RUD Tecdos Pi-Gamma is a flexible 2-in-1 chain drive system specially designed for vertical and horizontal applications. It has a fixed chain deflection of 180° or a flexible chain deflection between 90° and 180°. Thanks to its flexibility, it ensures greater efficiency during construction work in tunnels. Depending on the version, a Tecdos Pi-Gamma drive can achieve tensile forces of up to 260 kN.
RUD Tecdos Omega Drive offers a solution for linear or rotary movements in tunnel construction. This drive system has a wrap angle of 180° and, depending on the application, is either attached to the load to be moved and pulls it along the round steel chain or it moves the chain from a different location. The standard variant of the Tecdos Omega Drive system creates tensile forces of up to 260 kN per drive.
Wide Range of Applications
RUD Tecdos drive technology is used in lifting devices in tunnel construction, for example, to lift heavy equipment to the tunnel ceiling or to lift and lower vertical drills. The robust technology can also be used extensively in curved drives, belt storage systems or conveyor belts, as well as in transport trolleys and transport racks. The drive solution from RUD is also used in cutting devices, reinforcement cranes and shaft lowering systems.
“Our Tecdos drive systems can definitely handle weights of up to 25 tonnes. Theoretically, we are not restricted in terms of upper limits and can double or triple the number of drives if larger loads need to be moved,” emphasises Olfert.
