Spring-applied brakes

These systems have a wide range of use as holding brakes and emergency brakes that are locked by the spring when in a passive state. The release of the brake occurs hydraulically, pneumatically, or electrically. Examples of application are safety brakes in heavy industry, conveyor systems, all types of hoisting, and obviously in general mechanical engineering.
