28 plates per shift
For the production of prestressed track carrier plates in Germany, Weckenmann and the company Max Bögl jointly developed a production plant which enables an optimum flow of materials.
In a production pit various moulds are set depending on the requirements at hand. Four tensioning cylinders drive the clamping jaw into the end of the pit and out again completely synchronically. The path measurement and recording of this follows electronically. Even the preparation of pre-stressed steel works with a minimum length tolerance of maximum 20 mm for a total length of 80 m. In order to flexibly design the concrete equipment, the radio-controlled concrete spreader is rotatable to 90°. The discharge width is 2.5 m, the capacity around 6 cubic metres of concrete. In addition, the plant has a screed over the complete production width of up to 7 m. A multifunctional trolley on the same track manages the deployment and retrieval of the tarpaulin. In the end up to 10 tons of prefabricated elements are clamped and lifted with a vacuum cross beam and thus synchronically raised by five cylinders to avoid tilting in the shape. 28 plates are completed in this way per shift.
ROUTES FOR ICE & CO.
"A crucial factor in the decision to award the contract to Weckenmann was the quality and availability of the plant", explains Gerhard Dorr who was responsible for the project at Max Bögl in the Neumarkt location. "We cannot afford breaks in production due to very tight order specifications." In addition, Weckenmann could begin operations in the plant in only 18 weeks from the placing of the order. Other products can also be manufactured in the plant to enable production capacity. Max Bögl's route technology FFB is not only used on ICE routes in Germany but also in Chinese railbound high-speed networks, including in the construction of the world's longest high-speed route between Peking and Shanghai. Over 380,000 track supporting slabs will be built on a length of 1,270 kilometres.
