Big Order: Doppstadt Belt Drums Drive Conveyor Systems in South-East Asia

In an international tender the quality of Doppstadt belt drums has won through. World-famous technology enterprises from Australia, South Africa and Europe participated in a tender for the order of the Hongsha Power generation company, which supplies Laos and Thailand with electricity. For its brown coal mining branch the enterprise planned the extension and renovation of its conveyor systems. Four large belt drums should be delivered, drive, return or tensioning drums to keep the conveyor belts running.

Failure-Free Operation around the Clock

The Doppstadt belt drum production division in Calbe on the Saale River was awarded the contract. "The performance and the lifetime of our drum was convincing.", Jörg Amend, conveyor technology division manager at Doppstadt Calbe GmbH, explains. "In 1992 we delivered belt drums to the south-east Asian enterprise for the first time. To this day, they have been running: around the clock and without failure." This is extremely important because: if the belt drum fails the plant stands still resulting in considerable economic damages for the operator. "There are special climatic conditions in Laos", Amend says. "The rainy season lasts six months, the temperatures rise up to 40° C and the air humidity is just under 90 per cent. This is what the material and equipment have to resist". Belt drums from other suppliers, which Hongsha used for some time, have never achieved the lifetime that the customer requested and did not meet the high requirements.

Follow-Up Order Placed

But not only the high quality of the drums was decisive for the award, but even the price-performance ratio and the accuracy of production. Jörg Amend: "We could convince our partners that we offer an outstanding quality at a good price, we develop suitable drums within a short time and deliver them in time". A follow-up order has already been placed: As soon as the four new belt drums were installed, the company ordered another nine. They will be delivered in December.
