High developed machining of engineered belt pulleys


Since beginning of 2018 Doppstadt manufacture most of the large engineered belt pulleys at the new invested high developed CNC machining center TACCHI. With a turning diameter more than 3.000 mm and a length of 10.000 mm we are able to realize the machining of currently all kind of largest engineered belt pulleys. The new machining center offer a wide range of machining solutions such as turning, milling, drilling and boring.

With this new investment we are “Fit For the Future”

To Japan by Air Freight: Doppstadt Delivers Belt Drums at Record Speed 

Conveyor plants at standstill cost money. A lot of money. Therefore, its stands to reason that a big Japanese group of technology companies wanted to put the overhauled conveyor plant into operation as quickly as possible.

For this purpose, idler and drive drums up to 1600 mm diameter manufactured by Doppstadt Calbe GmbH were required. And that quickly. The desired delivery date was: within 15 weeks. This request was Doppstadt's first priority. We increased the speed in all areas: in the assembly, the packaging and the transport. Without neglecting the product quality, of course. After all, speediness is a question of organization and project management and not just acceleration of the work sequence.

Finally, Doppstadt delivered the drums even three weeks before the required date - by express, because instead of sending them by ship we transported the freight with several tons of weight by plane. In this sector, we cooperate with forwarders who can package and transport such a weight safely and professionally. Conclusion: Even in a greater hurry than usual, Doppstadt is reliable.

For highest demands

Belt Pulleys

Belt pulleys from Calbe move the largest transporting plants in South America. The brand "Doppstadt“ guarantees reliability and operational safety. Doppstadt- technology, i. e. driving and tail pulleys, tension and snub pulleys are working in overland and face conveyors, conveying bridges, excavators etc. Belt pulleys from Calbe can be equipped with various bearings. The diameters range up to 3000 mm and the face length from 600 mm to 3500 mm.

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.


Production

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.
