Any other use or excessive usage shall be deemed improper! Possible applications of the INTORQ spring-applied brake ❚ No explosive or aggressive atmosphere. -
Page 12: Technical Specifications
The spring-applied brake is designed for converting mechanical work and kinetic energy into heat energy. Due to the static braking torque, loads can be held at standstill. Emergency braking is possible at high speed of rotation. The wear increases as the switching energy increases. INTORQ | BA 14.0199 | 08/2016... - Page 13 Increased breakaway torque is common in particular after long downtimes in humid environments where temperatures vary. ❚ If the brake is used as a pure holding brake without dynamic load, the friction lining must be reactivated regularly.
