Eye catcher in Hall 1: The new Q 1.7 attracts a lot of attention
Thoma Aufzüge presented itself at the Augsburg trade fair as a specialist for special systems and controls and introduced its innovative lift concept
Small groups formed around the illuminated glass shafts with the large red “Q 1.5” and “Q 1.7” nameplates visible from afar. Our Q‑series systems were among the crowd favourites at the latest Interlift in Augsburg in October and provided plenty to talk about among trade visitors and exhibitors who headed for the Thoma Aufzüge stand in Hall 1. Numerous smartphones were pulled out and filmed as the low-maintenance toothed belt drives moved the slowly gliding platform of the Q 1.5 and the much faster cabin of the Q 1.7 up and down in continuous operation.
A number of curious visitors could not resist and also took a test drive. Many appreciative comments and the great interest shown by potential private and commercial customers confirmed our commitment to continue focussing on quality and innovation — also with our special systems.
Visitors to the trade fair were able to marvel at how versatile we are in realising individual customer wishes thanks to our in-house metal production and our extensive expertise on several screens and a large picture gallery. The question “And you build all of that yourself?” was often asked when they learnt that Thoma, as a medium-sized company, manufactures many essential components itself, from individual components to shaft equipment, control systems and customised cabins and can offer almost any customised solution regardless of standard dimensions. Passenger lifts with a minimal floor plan, round, glazed cabins, spacious cages for loads weighing tonnes — the pictures on our stand spoke for themselves. We also present many other examples at http://www.thoma-aufzuege.de/referenzen/.
At the trade fair, we also presented a sample of our latest control system generation TMS 320, which has been in operation for more than two years and with which we have already equipped around 50 lift systems. With this so-called bus control system, in which information between individual units and the central computer is only transmitted digitally via the bus lines, many technical features can be implemented, including the division into a control computer and a car computer and the linking of each to a floor computer. It also allows the hardware in control systems and the size of control cabinets to be reduced. Further advantages include digital path recording (shaft copying) and an improved fault memory.
The intensive development work for our Q series now seems to be gradually paying off. It began with the endeavour to realise simple retrofits on a very small footprint with a very low shaft pit and led to the development of the Thoma Lifter Q 1.2 and Q 1.5, compact platform lifts in accordance with the Machinery Directive, which we supply as a complete component with a finished glass shaft and can install within one to two working days. The “Q” stands for the square floor plan, the numbers indicate the shaft’s external dimensions — 1.2 or 1.5 metres depending on the model, whereby the compact design means that a large proportion of the floor space (76%) is taken up by the platform. Another special feature: access points can be arranged on all four sides of the shaft.
As specialists for special systems and control units, we have now used this as a basis to develop a passenger lift that complies with the Lift Directive, i.e. with a closed lift car and automatic sliding doors as well as a higher travel speed, the Q 1.7. Its prototype already caused a stir at the Interlift in spring 2022.
We have now presented the finished model of the Q 1.7 at the international trade fair, which is characterised above all by the lightweight construction of the cabin. This means that the original lift, which can only be operated by “dead man’s control” at a speed of just 0.15 metres per second, has matured into a fully-fledged lift for everyone. The digital BUS control system in the shaft head ensures that the cabin travels to up to twelve stops with millimetre precision and without any crawling. The Q 1.7 transports the maximum payload of 675 kg or 9 people to a height of up to 20 metres in one metre per second. The tried-and-tested arrangement of access points on all four sides of the lift system is also possible. The Q 1.7 is also available with “simple” through-loading in a rectangular shape with variable dimensions. As with all Q models, we manufacture the scaffolding from aluminium for a durable outdoor design.
