Engineered and manufactured in Germany BUEL® thrusters have been developed on basis of decades of experience in drive technology and its components. Highest quality standards in all operating divisions of the PINTSCH BUBENZER GmbH are the basis for functional safety of the BUEL® thrusters. With regard to applications and operational capability, there are nearly no limits. Primary purpose is the use as brake release thruster in industrial drum and disc brakes.

Drum Brake Type EBN-2 St as 2-step brake - Functional description Two directions are becoming apparent today in the use of double shoe brakes - apart from lifting gear brakes: First of all, the use as a straight stopping brake and secondly as a brake for markedly special applications. The 2-step brake offers exceptional possibilities in this area of special tasks. This type designation is to be understood as covering brakes which: a) act with an adjustable partial torque A immediately after the actuator is switched off and in which b) the remaining braking torque B takes effect in...
