Shaft copying systems
Safe, precise, robust
- Travel height up to 392 m
- Safety: SIL3 certified
- Dynamic: Travel speed up to 5 m/s
- Precision: Resolution up to 1 mm
- Direct: Absolute positioning
Absolute positioning of the elevator car for travel heights up to 392 m.
The contactless absolute measuring system for shaft copying – also called shaft information or positioning system – has an extremely compact, very robust design. In addition to the sensor, which detects the position of the elevator car 100% slip-free, it also includes the appropriate evaluation unit, a so-called Position Supervisor Unit (PSU). The safe system therefore consists of a SIL3-certified sensor and a suitable evaluation unit. This enables elevator and safety functions to be implemented in accordance with EN81-20/21/50 and ASME A17.

Technology in detail
Saves time and costs
One of Kübler's unique selling points is its ease of mounting. Using carabiners, the stainless steel band can easily be attached to the respective mounting set via "plug & play". In the shaft pit, the belt is pretensioned by a spring. The essential installation instructions are available both on the strip packaging and directly on the sensor. No more tedious scrolling through user manuals or searching in PDF files.
Suitable for the tightest spaces
The extremely compact design not only saves space but also costs. Especially for elevators with reduced shaft head, shaft copying from Kübler offers advantages. It is possible to mount the sensors on, next to, or under the cabin.
Reliable and durable
The robust stainless steel band with its rounded edges is mounted directly to the guide rails using a mounting set. It can neither be influenced by temperature fluctuations nor by magnetic influences during mounting, such as the use of magnetized screwdrivers. The code is punched into the stainless steel strip. As a result, Kübler dispenses with additional gluing processes and thus ensures maximum robustness of the strip in the application.
Precise positioning
Loss of absolute position or correction of position by reference switches (magnetic vanes) is a thing of the past. With Kübler's shaft copying, the position of the elevator car can be determined 100% slip-free. The sensor is mounted directly on the elevator car and can directly determine the absolute position without additional reference markers in the shaft. Slippage of the cable at the drive has no effect on the measuring result. The sensor system is an absolute value system which can record a unique absolute position value at any point of the code band.
Reduce total costs
With the SIL3 certified Position Supervisor Unit (PSU), evaluation unit, or Safe Box, elevator and safety functions can be realized in accordance with EN81-20/21/50. These include emergency limit switches, UCM (Unintended Car Movement), inspection limit switches, overspeed inspection, or door bypass. Kübler's safe system allows numerous existing components in the elevator shaft to be eliminated, such as limit switches, magnetic vanes, reference switches, or door zone magnets. In addition to procurement costs, this saves installation and maintenance time.
