Definitions

  • the present invention relates to a Schlauchaufrollvortechnische for fire hoses, and a system comprising such Schlauchaufrollvortechnische.
  • Fire hoses are usually made of long hose sections, which are connected to each other with a hose coupling. In this way, hoses with an enormous length (for example, 2000 m) are provided for use. After use, these long hoses should be transported back to the fire truck in the simplest and quickest possible way.
  • systems are known from the prior art. For example, refer to the corresponding disclosure of EP-A-0 631 976 pointed out, according to which a hose is pulled over two transport rollers in the vehicle. The tube is thereby pressed by means of two acting on the transport rollers pinch rollers to remove remaining in the hose, originating from the use of residual water.
