Dormentes de concreto protendido
Por muitos anos, dormentes de concreto protendido para sistemas ferroviários têm substituído o uso de dormentes de madeira ou metálicos em redes ferroviárias públicas ou privadas. Eles duram mais que seus correspondentes em madeira e não precisam ser impregnados com óleo de alcatrão mineral. Quase todas as geometrias de dormentes podem ser produzidas utilizando-se concreto protendido.
Dormentes de concreto protendido são fornecidos direto da fábrica, prontos para serem assentados. O que significa que toda a armação foi montada e pré-tensionada dentro do dormente conforme os padrões durante o processo de manufatura.

Production of prestressed concrete sleepers using the late removal of casing
On the basis of an internal study carried out in 2002 that investigated all the current options available on the market for the production of prestressed concrete sleepers in terms of economy, quality and the use of energy, Leonhard Moll Betonwerke chose at the end of 2002 a system for the production of prestressed concrete sleepers using the late removal of the casing. Here, the experience of Moll, which had already produced several million prestressed concrete sleepers in the past, was combined with the plant engineering expertise of Vollert. The result is a plant that sets new standards worldwide with regard to economy, quality and energy consumption.
