Elevators and Escalators - Safety first and foremost

Elevators are one of the safest means of transportation of the world.
Our switchgear make a major contribution to this safety. Elevator technology indeed is one of the industries, in which we have acquired specific knowhow and for which we offer customised switchgear since the early days of our company’s existence.

Our elevator switchgear lock and monitor the elevator doors. They are used for various applications both in the active and the passive safety circuit of the elevator system either to monitor individual components or as electrically resettable limit switch in the shaft head or in the shaft pit. We also have developed customised switchgear for special applications such as the electrical shutdown of the elevator system upon activation of the speed governor.

A comprehensive programme

With this comprehensive programme, we can offer the manufacturers of elevators and escalators a large variety of switchgear and switching systems, which meet the harmonised requirements of the worldwide applicable directives and standards. Besides tried-and-tested technologies, we also implement innovative methods offering technical and economical advantages, for instance the USP non-contact positioning system, which is used in thousands of elevators all over the world.

Worldwide partner of the elevator manufacturer

We successfully collaborate with the world market leaders as well as many medium-sized manufacturers of elevator technology from all over the globe. Our switchgear are used, wherever high-rise buildings are erected or elevators are modernized. The spectrum ranges from apartment towers and multi-storey buildings in Sao Paulo, London, Shanghai or Munich over residential buildings all over the world up to freight elevators in industrial buildings.

Elementary: highest reliability

It is self-evident that these switchgear feature a reliable function for many years. We are happy to say that “Schmersal switches” are also in the elevator technology synonym to quality and longevity. We accept the challenge to set new standards and to provide our customers with products featuring effective advantages to face the cutthroat competition.

Master topical challenges

The elevator technology is currently facing major challenges, as the cost pressure keeps increasing. Nowadays, elevator constructions, which can be quickly assembled and put into operation, are in great demand. These are the specifications that we keep in mind when developing new generations of elevator switchgear, whereby an increasing importance is attached to the customer assembly aspect as well.

Retrofitting: a growth market

Our elevator switchgear are frequently used for the modernisation of existing elevator systems. We offer a safety-monitoring module as interface for the USP non-contact absolute encoder to convert the measured absolute values into 24 VDC signals. In this way, modern techniques can be integrated in the existing older technology.

PESSRAL and the consequences

PESSRAL, a supplement to the European standard EN 81-1/2, lays the foundations for the integration of programmable electronic safety bus systems in the elevator technology. The implementation of this directive will have significant impact on the future construction of elevator systems. The Schmersal Group has acquired comprehensive experience with programmable safety controllers in machinery and plant construction and is actively participating to the discussion regarding PESSRAL and the development of programmable electronic safety systems for the elevator construction.

Wanted: cooperation partners for new technologies

PESSRAL will also influence the relations of the manufacturers of elevator switchgear and controllers with their customers of the elevator construction industry. We therefore are in contact with the medium-sized controller manufacturers with the objective to establish standards and to commonly offer complete safety systems. This approach will help the medium-sized specialists strengthening their position on the fiercely competitive market and make us, together with our partners, the pioneer of this new technology on the elevator market.
