One of the leading names in manufacturing firefighting equipment called on us to create crucial functional parts for a ‘washing system’ to clean fire hoses. Used for hose upkeep, the machine has been registered for a patent by our customer, Barth Feuerwehrtechnik.
German law stipulates that fire hoses must be cleaned after each use. The reason: Dirt, dust and even toxic remnants of the last fire could contaminate the hoses and prevent them from working effectively during the next emergency. But there’s nothing easy about cleaning 22m fire hoses. That didn’t stop Barth Feuerwehrtechnik. The company designed a patented hose maintenance system called Halbstrasse. How it works: A linear sleigh pulls the hoses through the cleaning unit and along the 11m-long system, finally bringing the hoses back to where they started. At this point, the hoses are removed to dry.
The guide rail on the sleigh is a stainless steel section that we first laser-cut and then bent a number of times. Almost 3m long, the section boasts a complex geometry – one we produced using our Hämmerle equipment. Thanks to 3-point bending technology, we can achieve the ultimate in angle precision as well as a uniform bending angle – and maintain a uniform bending strength along the entire length. The equipment’s generous stroke and edge clearances in front of and behind the machine mean we can manufacture the intricate profile with incredible precision. And how do we know that bending processes and other procedures will turn out just the way we want? Our deep expertise and solid track record take care of that.
The stainless steel basins along which the hoses travel are manufactured using our Trumpf precision laser cutting system.
