Three-part telescopic apron

Vertical telescopic lift car apron for use in low shaft pits. In the case of shaft pits that are at least 400 mm deep, the required length of 750 mm can be produced by extending the telescopic apron.

 

The apron is not extended during normal operation and has a height of around 300 mm. The retracted apron sheets are held in place by a magnet. If released or if a power failure occurs, the apron sheets move to the required apron height automatically. The telescopic apron must then be put back in place manually by trained personnel. Thereafter, the system can be used again in normal operation. To ensure that the system functions correctly, the shaft door emergency release devices must be fitted with an additional door contact to be provided by the customer. These measures must be agreed with the responsible inspection authority.
