Coupling and Brake Systems for Drive Components

Transport and conveying engineering,
PO Box 4010,
57356 Other,

Tüschen & Zimmermann GmbH & Co. KG, based in Lennestadt, Germany, produces coupling and brake systems for underground mining. Rotary shock absorbing tz–couplings engineered with length compensation enable the easy exchange of elastomers without separation of drive components. They are an important part of the “Building Block” principle, allowing adaptability to individual drive units.

The main applications are the drive units of chain scraper conveyors, crushers, belt conveyors, hoists, pumps and other underground machinery. This system is not limited only for direct drive couplings, but allows also the integration of fluid dynamic couplings and their multi purpose applications.


This program is extended by the development of brake and holding devices based on the disc brake principle. Components are used as chain pretension devices in applications such as chain scraper conveyors and plow system drives. tz–brake systems became a standard element for stopping belt conveyors and for controlling the deceleration of belt conveyors and crushers.

Today, tz–components can be used for applications with a total maximum output torque of up to 650,000Nm. Covering a range from 2.2kW to 1,000kW drives, tz–standard components are supplied for the connection of underground motors and gearboxes. Close cooperation with our customers in solving drive and deceleration problems continuously enhances our range of applications.


tz’s electronic controlled systems for carefully and safely accelerating and decelerating conveying devices, have proven their worth in underground use for many years. Continuous development and improvement, using our own test stand, assures high technical know how.

tz supports on long–standing experiences in construction of transmission engineering and interpretation how we are able to produce special manufactures, intensive quality–protection and the know–how of our technical departments. Our company has also an effective quality–management–system according by DIN EN ISO 9001-2000.
