Installation and Maintenance Manual  

CB8-E 

 

Spring chamber: 

Allows the continuous adjustment of spring torque, by adjusting the preload of the 
spring. 

Protection cover:  The protection cover avoids the fouling of the release mechanism and guarantees 

the operational reliability of the brake even under rough environmental conditions. 
Removable caps allow the fast access to the manual release and enable the 
maintenance personnel easily to control the reserve stroke. 

Sensors: 

Sensors can be used to check the lining wear and to check if the brake is open.
