“Inline” Height Adjustment for Heavy-load Columns in Medicine and Rehab

“Inline” Height Adjustment for Heavy-load Columns in Medicine and Rehab

Move heavy loads smoothly – work ergonomically

When it comes to operating tables and X-ray tables, it’s particularly important that they be easy to handle and capable of carrying heavy weights. Ketterer has developed a linear drive that completely integrates into the lifting column of the treatment table without any disruptive components sticking out. This enables optimal freedom of motion for doctors and staff as well as unproblematic treatment, even for heavy patients. Thus, the height adjustment system fulfills all requirements for ergonomic work in doctor’s offices and clinics.

The drive’s linear motion is generated by a gear motor-spindle combination. The table’s height can be adjusted seamlessly with a manual switch. Furthermore, the drive is extremely quiet and maintenance-free – two major pluses in the field of medicine. The compact drive is flexibly customizable for lifting columns of all sizes and for varying load requirements, making it suitable for a whole array of further uses – for example, in laboratories, workshops or even in kitchen furniture.

Double-stroke Telescoping Fast Crank Lifting System

No electricity yet smooth: maximum lift with minimum effort

Ketterer has taken the well-being of its customers and the environment into account with its manual, gas spring supported fast crank lifting system for adjustable sit-to-stand workstations: the stepless, double-stroke telescoping height adjustment is extremely fast and convenient. Moreover, the “Green Solution” does not require any electricity which not only saves on energy costs but also on complicated wiring. The double-telescoping spindle system allows for a wide range of working positions – from a child’s table up to an ergonomically designed standing desk for grown-ups.

The fast crank lifting system is suitable for double-stroke telescoping table frames that have either one or two legs. The table can easily be cranked up and down, even with a weight load of up to 40 kg. While other systems work with spring packs or counterbalances, the Ketterer system is self-locking, i.e., it stays put regardless of the respective weight load. A special bonus: The system is available separately without a frame and is custom-made to meet the customer’s needs and specifications.

Exterior mirror adjuster for agricultural machinery

Exterior Mirror Adjuster for Agricultural Machinery

Quickly, flexibly and noiselessly adjust exterior mirrors

Commercial agricultural vehicles, such as tractors with trailers, must often maneuver backwards in places with a limited view. There isn't always a second person ready to help the driver. But even in urban environments, it is often difficult for transportation vehicles, buses or large trucks to maintain a view when reversing. That makes functional, flexible exterior mirrors are all the more important.

With its innovative exterior mirror adjusters, Ketterer has developed a solution that ensures optimal and safe rear vision. The exterior mirror can be completely extended or retracted from inside the vehicle in just six seconds by pressing a button – and with a very low noise level. This is made possible by a gear motor with a spindle and a spindle nut, producing a linear motion.

The gear unit is compact and can withstand temperatures of -27 to +60°C. Thanks to the robust design, the exterior mirror adjuster is virtually maintenance free.

Special drive for fully automated window closing system

Special drive for fully automated window closing system

Modern architecture – new challenges for drive solutions

Just a few meters from Zurich’s main railway station is one of the most state-of-the-art destinations in the city. This area around the former Löwenbräu brewery known as the Löwenbräu-Areal is nestled below the towering complex of a 70-meter residential high-rise that is exceptionally bold in terms of both form and dimensions.

The modern architecture here called for a completely new kind of window closing system. Rather like a garage door, windows open all the way and are fully automatically raised to be parallel to the ceiling. The idea for this unique closing system presented a great challenge when it came to the technical implementation. With windows of three by three metres in size, the mechanisms need to be able to withstand huge loads. The sophisticated interplay between the lifting and tilting functions was made possible by deploying Ketterer spindle and mechanical transmission solutions. Due to the compact design of Ketterer drives, this window closing system is able to fully accommodate the demands of modern architecture.
