Reversing bearing block
The reversing bearing block is used for the external actuation of door interlocks at lifts. By bevel gears the movement of the roller lever is deflected by 90 degrees. The gear head can be delivered in four different positions. It is equipped with an additional emergency release triangle. The connection rod between reversing bearing block and door interlock can be any length. For confined spaces a shortened version of the reversing bearing block is available.
