We will find a good solution
Retrofitting an elevator system in or on a building is almost always a major challenge.
Shaft dimensions, sensitive building fabric, statics, inadequate electrics — especially when retrofitting older or even historic buildings, there are often many technical problems to solve. For Thoma Aufzüge, this is precisely a “supreme discipline”. Here we can apply our entire know-how and our great experience in the construction of special systems and are independent of standard dimensions due to our own production. Because an “off-the-shelf” system with components from the supplier market is usually out of the question for retrofits.
Often, a change of use or new regulations make it necessary to retrofit an elevator, for example to make stores or public buildings accessible to people with physical disabilities, wheelchair users or parents with strollers.
Simple and cost-effective:
the Thoma Lifter
There are a variety of solutions for retrofits. First of all, it has to be clarified whether it has to be an elevator system with all its advantages, but also higher costs, or alternatively a simplified and more cost-effective system such as the Thoma Lifter, our patented platform lift.
The Thoma Lifter can do a lot — but not everything. If a building is to be retrofitted with a special elevator system, our customers are often faced with several hurdles:
- unfavorable shaft dimensions, i.e.: shaft pits are not deep enough or the shaft heads are too shallow.
- The statics of the building cannot bear the additional loads (weights) caused by the plant.
- The structure of the building does not allow the installation to be fixed in the building.
- It is difficult to meet the requirements of the building inspectorate and the preservation order.
It is therefore a good thing that our planning department has already realized a large number of elevators as special installations and can fall back on a very comprehensive archive. Plans and drawings for customers as well as our in-house production drawings are very detailed. We therefore usually identify problems as early as the quotation phase.
Lack of space is not a problem for us
Low shaft pits and excessively shallow shaft heads can usually be compensated for with a range of safety devices. Lack of space is a common problem, especially in old buildings. Then, for example, particularly space-saving doors or a traction elevator with drum drive can be a solution. This type of drive eliminates the counterweight, saving further floor space. In many cases, there is neither space nor a sufficiently stable building structure for a conventional elevator shaft. In such cases, we use a self-supporting steel frame from our own production.
If we are faced with completely new tasks, we benefit from our many years of experience and the high technical competence of our team. And since the employees of our own electrical and mechanical production are used to building special systems, we have solved every problem so far. When the going gets tough, we’re flexible. That’s our way of building elevators.
Short delivery time —
An uncomplicated and cost-effective solution is the Thoma Lifter, our innovative platform lift with its own glazed aluminum shaft frame, which can be mounted on exterior as well as interior facades on a very small footprint. Due to simple planning, short delivery time and uncomplicated assembly, the Thoma Lifter is particularly suitable for private residential buildings. However, the compact platform lift also proves its worth in the public sector, especially as it is durable, low-maintenance and energy-saving. There are two standard sizes for the design of the lift, which are exceptionally not changeable. This allows us to match the design to the respective ambience and we also offer a version that we have developed specifically for the needs of wheelchair users.
