Pioneering in Drive Technology
With VARIACTO®, entirely new solution approaches arise. With this unique push-pull chain drive, you achieve more goals than before – pushing farther and higher. Change the drive type with VARIACTO® and optimize the use of space in your system layout.
VARIACTO® opens up numerous new possibilities, whether in vertical or horizontal thrust. Thanks to its flexible use, VARIACTO® outperforms conventional linear drives.
Minimal Space Requirement
With VARIACTO®, you only need minimal space. The low housing height and the redirection of the chain by 90° in the drive unit or 180° in the chain station enable uniquely flat designs and open up new possibilities in construction. With the minimal height of the drive, you can still move heavy loads over long distances. Unlike traditional linear drives, the space of the drive is decoupled from the space requirement of the chain lifting element.
iwis push-pull chains are based on welltested roller chains and are thus optimized for maximum performance and efficiency. With a compact push-pull chain drive, users can move large loads with minimal effort. Thanks to the clever redirection of the chain, the combination of load-free feeding and a thrust phase with maximum load is achieved.
(nearly) Unlimited Range
Limited drive technology is a thing of the past. Move heavy loads individually over long distances with the VARIACTO® pushpull chain drive. While conventional linear drives are strictly limited in their range, the VARIACTO® push-pull chain drive overcomes distances of up to 15 meters, depending on the design.
VARIACTO® can be integrated into existing applications and easily adapted. A wide selection of initial lubricants ensures successful operation even in challenging environments. The modular chain station can be easily expanded to accommodate the required chain length. Various options for connecting the chain to the application ensure compatibility with your machine.
An Alternative to Conventional Drives
In comparison to conventional drives, VARIACTO® is a very clean and quiet solution. Since the drive does not include hydraulic or pneumatic lines, and hydraulic aggregates are not necessary, there is no risk of leakage. Noise from pumps and compressed air leakage is also eliminated.
Sustainable Drive Solution
The VARIACTO® push-pull chain drive is a mechanical system with high efficiency and suitability for direct electric drive. Problematic materials are not used in the production of the system. The high wear resistance and maintenance-friendly design of VARIACTO® ensure sustainable operation throughout its entire lifespan.
