Our „crown jewels“
We like to define what we understand by quality ourselves. That’s why we have always manufactured all the components that are essential to us in our own production facilities.
On the one hand, this makes us independent of a market that is primarily concerned with cutting costs. On the other hand, it allows us to respond very flexibly to our customers’ wishes. The development and manufacture of our own elevator controls has been one of our core competencies since the early days of the company. In a sense, they are our electronic “crown jewels”.
We perform pioneering work
Time and again, Thoma Aufzüge has done pioneering work in this area and surprised the industry with innovative technology: for example, with our self-developed sensor pushbuttons, the relay controls that led to a reduction in the size of the controls, our adaptive destination selection controls with different operating modes, or the improved connection of control and regulation for direct entry and quick start.
Even though Thoma Aufzüge has been producing components for other elevator companies since 1967 — for which, by the way, we are still able to supply spare parts — it was only a few years ago that we decided to further expand Thoma Components as an independent business unit. The division made its first official appearance under this name in 2017 at the Lift Fair in Augsburg. In the meantime, our product portfolio no longer only includes controllers, but also regulators, spare parts for controllers such as circuit boards and sensor pushbuttons, and long-life LED tiles manufactured according to our specifications, which can be installed very flexibly. In short: You can get almost everything from us — up to complete elevator systems according to your specifications.
A wide range of options
Our mini controller, which we developed for simple elevator systems, has been available since 2010 and can be used for up to twelve stops. The fusion of control and regulation in one component was a novelty on the elevator market at that time. The advantage of this control system, which is intended for normal individual installations, is that it has considerably fewer components. Incidentally, the mini-controller is also used in the Thoma Lifter developed by Thoma Aufzüge and produced here — a platform elevator in accordance with the Machinery Directive.
Our “big” control system can handle all options that arise in the standard, no matter if different types of fire evacuations, fire department controls or special trips with different prioritizations (common e.g. in hospitals). The combination of components enables digital direct entry — with absolutely no creep path — and a quick start that is unparalleled in the elevator industry. In this way, we have once again succeeded in significantly reducing stop loss times.
Learning target selection controls optimize operation
The Thoma destination selection control algorithm includes several operating modes that automatically measure the elevator group requirements. In simple terms, how many people are waiting on which floor, and which floor they want to reach. Different elevator control requirements, such as busy mornings or daily lunch breaks, result in automatic adjustments to the group control. The destination selection control is adaptive and optimizes itself via stochastic parameters. The variants are offered with different input terminals and can be adapted to customer requirements.
Since the development of our first sensor scanners some 40 years ago — which were initially not scanners as we understand them today, but miniature photoelectric sensors — we have also continuously developed these components. By the way, the “behind glass” variant is self-calibrating and automatically adjusts to the glass thickness and ambient temperatures. We even offer a special variant for installation behind laminated safety glass. A sensible design for glass elevators if the call panels are to be fixed in the glass.
Thoma quality for long service life
In addition to push buttons, Thoma Components has the latest developments in LED technology, such as our continuation indicators, lighting panels or LED tiles for cabin lighting. Here, too, our wealth of experience from elevator construction and installation has been incorporated into the product development: Our LED tiles can be adjusted in size via predetermined breaking points, they are easy to connect to each other, have a 12-volt emergency light function, are dimmable as standard and can be glued directly to the basic ceiling or alternatively screwed on. It goes without saying that they are manufactured in the usual Thoma quality and have a long service life.
Because what applies to our elevators is naturally also the standard for our components: We build them for long, trouble-free operation. They should not become technically obsolete, which is why we offer upgrades for older control systems. Up to the latest generation, the TMS320, individual elements can be combined. We call this design downward compatible. If a fault does occur, that’s no problem either: we have a large range of spare parts — even for the very first generation controllers. In addition, we can usually repair older parts in our electrical department.
