Shaft copying systems

Absolute positioning of the elevator car for travel heights of up to 392 m.

The non-contact absolute measuring system for shaft copying - also known as a shaft information or positioning system - is characterized by an extremely compact design and high robustness. 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, consisting of a SIL3-certified sensor and matching evaluation unit. This enables elevator and safety functions to be implemented in accordance with EN 81-20/21/50.

Shaft copying systems

Absolute positioning of the elevator car for travel heights of up to 392 m.

Sensors – reliable determination of position and speed values

Kübler offers various sensors for this purpose. The Ants LEB02 serves as a classic shaft copying system for precise positioning of the elevator car. The SIL3-certified Ants LES02 and Ants LES03 sensors can also be combined with various evaluation units from Kübler. Kübler sensors are particularly notable for their compact and robust design.

MODBOX - system solution for modernization projects in elevator technology

The MODBOX is a control-independent solution for modernization projects in elevator technology. Housed in an IP66-rated plastic enclosure, it integrates the PSU03 or SGT03 evaluation unit, buffer batteries, and a power supply. The power supply is designed to match the power consumption of the installed safety gear. Thanks to the emergency power buffering, it is ensured that the safety gear can be released for emergency rescue even in the event of a blackout. All components inside the enclosure are pre-wired.

Safe systems – implementation of safety functions

By combining the sensor and evaluation unit, safety functions in accordance with EN 81-20/21/50 can be implemented. Kübler Safe Systems thus make a significant contribution to the digitalization of elevator systems. This eliminates the need for numerous mechanical components such as limit switches or even the classic speed limiter. This saves space, time, and costs.
