How does an elevator control work

With an elevator system you secure the transport of people and loads

Drives for elevator systems

Basically, a distinction is made between two types of drives in elevator systems, each of which is suitable for different areas of application and lifting heights.

Cable drive

The so-called traction sheave is located above the elevator shaft. The steel cables that hold the car are guided over the traction sheave and at least one pulley. The ropes can be almost any length, so this type of drive is also suitable for high-rise buildings is. In addition, with a rope drive a high driving speed will be realized.

The elevator cage is on one side of the rope and a counterweight on the other. The counterweight weighs about as much as the half-full elevator cage.

Hydraulic drive

With the hydraulic drive, the elevator cabin is moved by means of hydraulic pistons. The The head is limited to around 15 meters and it will be lower transport speeds than achieved with cable-operated elevators.

Especially when the frequency of use is low A hydraulically operated elevator wins over the rope-operated models, as it is more efficient due to lower maintenance costs.

Control systems

Collective control

Modern elevator systems have intelligent control systems to optimize the number of stops per trip and to avoid empty trips as far as possible. Many elevators are equipped with a classic collective control. The users call the elevator and the collected orders are processed in a meaningful order. If someone wants to get on, the journey is interrupted on the corresponding floor. For small elevator systems this type of control is completely sufficient.

Destination control

For elevators with a high number of users the efficient system of destination call control is ideal. Here the users must already specify the target floor when calling the elevator. You will then be assigned the cabin that will bring you to the desired floor as quickly as possible. This control method is particularly suitable for multi-car elevators and regulates the journeys in such a way that maximum utilization guaranteed is.

Safety precautions for elevator systems

Modern elevator systems are nowadays very sure. You have the following safety precautions:

  • Emergency call system: If the technology fails, you can always reach an emergency call center and call for help.
  • Securing the landing doors with a Photoelectric barrier: The doors immediately interrupt the closing process if someone is still between them.
  • Safety gear: If the carrying mechanism fails, a safety device is triggered and the car stops. This works purely mechanically, so that it is ready for operation even in the event of a power failure.
  • Double securing of the suspension ropes: Each individual rope can carry more than the maximum load of the elevator. If one breaks, the other ropes can carry the cabin
  • Weight sensors measure the car load and warn in the event of an overload.
  • The review of the plant takes place at least every two years by an approved monitoring body such as the TÜV and by fitters from the elevator company.

Cost of an elevator system

How high the costs for an elevator system turn out to be is difficult to say in general terms. They depend on many different factors, such as: B .:

  • Delivery head: How many floors should be approached?
  • Load capacity: Should only people or loads be transported?
  • Remodeling work: Can the shaft be easily integrated into the building?
  • drive: Which type of drive should be used?

Depending on the properties desired, the costs can vary widely. A small elevator system for people who should only travel on two floors around 20,000 euros. On the other hand, with an elevator system, you have to transport people and loads and three floors or more can drive at a cost of at least 50,000 euros calculate. Added to this, depending on the installation effort Assembly costs between 3,000 and 7,000 euros.

You have these funding opportunities

In some cases, the installation or modernization of an elevator is considered eligible. For example, the Kreditanstalt für Wiederaufbau (KfW) subsidizes an elevator if the living space is designed to be barrier-free. With the KfW program 159 you receive a low-interest loan fromup to 50,000 euros for age-appropriate renovation. With the KfW program 455-B you can also receive an investment grant of up to ten percent of the cost and maximum toat 5,000 euros received for the barrier reduction measure.
