Discover the Belt Pulleys

Always at the pulse of the time


The year 2018 started with a very positive volume of orders for the belt drum construction division at Doppstadt Calbe GmbH.

The orders placed in the first two quarters of 2018 confirm the current positive development trends worldwide in the field of heavy materials handling equipment.

Quality, efficiency and performance are in demand in the market and our custom-made belt drums stand out because of these features. This was also verified by the great demand and the interested customers at the EXPOMIN trade show in Santiago de Chile in April. Our participation in this leading trade show with our partner, the TTM company, showed once again that it was the right decision to expand this market.

But not only on this continent, the belt drums from Calbe are preferred, but recent large-scale projects in Thailand, Laos and other mining regions prove the worldwide appreciation of our quality products as well.

Technical Data

Doppstadt manufactures and supplies high quality new conveyor systems designed and built in accordance with customer requirements or as replacement equipment.
Our belt drums can thereby be realized with flange bearings, sliding bearings or bearing baskets with various seal types (oil seal, labyrinth seals, Taconite seals, felt rings). Drive pulleys for shafts or couplings are available for single and double sided drives (optionally provided with keyed connections and/or with a remote cylindrical friction joint or conical sleeve). Deflection pulleys can be adapted to include slip monitoring systems such as speed monitoring ports. The system (including the belt drive surface) is also available in a smooth or profiled belt format or as a nubby surface in rubber, polyurethane as well as ceramic. The surface can be heat cured or cold glued.
Doppstadt belt-drives can be supplied for the desired operating conditions, in a welded construction or with I- and T-shaped clamping sets.


The SAP-aided sequence control is the basis for the economic fabrication. Modern machine tools and qualified specialists enable an efficient production. Optimum internal logistics supply every mounting station with the necessary parts in due time. The calculation of each part, the high manufacturing penetration, a high-quality paint and not least the systematic quality management comprising all the departments quarantee the long service life of the belt pulleys.
