More flexibility for greater efficiency: Tecdos Pi-Gamma, the innovative 2-in-1 drive system from RUD, scores with flexible deflection from 90 to 180 degrees. This makes the chain drive system suitable for horizontal, ascending and vertical movements. Whether on blast furnace closures, large industrial gates or even gangways for port facilities – the possible applications for Pi-Gamma are almost endless.
‘Our Pi-Gamma chain drive is a real all-rounder. With its flexible chain deflection, its suitability for use as a drive and deflection module, and its modular design, the system can meet almost any requirement,’ explains Anne Kühling, Head of Product Management at RUD Ketten Rieger & Dietz GmbH u. Co. KG.
Chain deflection 90 to 180 degrees
The complete Pi-Gamma system is a 2-in-1 head drive and is particularly suitable for horizontal, ascending or even vertical use with a fixed deflection of 180 degrees (Pi) or a flexible deflection of 90 to 180 degrees (Gamma). Thanks to its modular design, Tecdos Pi-Gamma is versatile and expandable.
Compact, lightweight and robust
As a 2-in-1 solution, Tecdos Pi-Gamma is also particularly compact: it is narrower and lighter than conventional systems. In its smallest version (Tec 6), the drive system has a pitch circle diameter of 58.4 mm and weighs 4.5 kg. Tecdos Pi-Gamma really comes into its own in confined spaces, moving even heavy loads with its relatively small size. The drive is weather- and corrosion-resistant.
Chain – the basis for the drive system
Tecdos Pi-Gamma is based on a wear-resistant, high-performance round link chain, also from RUD. Thanks to the chain drive, the system is particularly robust and resistant to dirt, sand, water, ice and other weather conditions. ‘This is a clear advantage over other alternatives, such as rack and pinion, sprocket, spindle or prockets solutions. Tecdos Pi-Gamma continues to run smoothly even when other drives reach their limits,’ emphasises Anne Kühling. The chain-based drive system scores highly with maximum operational reliability and a long service life.
Seven standard sizes, flexibly combinable
RUD manufactures the Tecdos Pi-Gamma drive in seven different sizes as standard: from the smallest version, Pi-Gamma Tec 6, to the largest version, Pi-Gamma Tec 260. Depending on the load and requirements, Tecdos Pi-Gamma drives can be combined with each other. Both horizontal and vertical applications are possible in multiple configurations, for example with two, three or even four strands. ‘Theoretically, there are no limits,’ emphasises Anne Kühling. The modular concept allows the drive to be powered by electric, hydraulic or pneumatic motors.
Tecdos drive technology
In addition to Tecdos Pi-Gamma for horizontal, ascending and vertical movements, RUD's Tecdos drive technology offers another system: Tecdos Omega Drive for linear and rotary movements. RUD Tecdos offers durable, reliable and safe components as well as complete technical solutions for every requirement. A range of standard components can be combined in a modular fashion.
