The experts at Safescape decided on the Agrale Marruá: a heavy-duty commercial vehicle with four-wheel drive from Brazil that was developed for military use. The name of the vehicle („wild bull“) is very fitting – from the bull bar in front of the grille to the platform. Beau McKenna: „The Marruá is ex- tremely robust. It has a payload of two tons, the manufacturing quality is excellent and the corrosion protection for the body and components as well: All body components are galvanized and the chassis is fully sealed. These are the best prerequisites for a long service life underground.“ HEAVY-DUTY OFFROAD VEHICLE WITH ELECTRIC DRIVE The integration of the electric drive in the vehicle also required a complete redesign of the cooling system for the battery packs, in- cluding the lines from the cooling unit to the battery pack. Safes- cape cooperated with the Australian Stauff subsidiary for this task. The reason: With a wide range of high-quality tube connec- tion components and systems, in particular for hydraulic sys- tems, Stauff manufactures and delivers customised tubes – worldwide, from their own subsidiaries and with partners. Stauff also provides this service for Safescape and the Bortana EV. In the first step, Safescape inquired about ready-to-install, three-dimensionally bent 19 mm tubes with machined ends from Stauff Corporation Pty Ltd. in Melbourne, for conveying the coolant to the powerful battery packs. Stauff received the order, 01 State-of-the-art machines ensure reproducible production of ready-to-install tubes 02 The bonnet of the Bortana conceals an electric drive with a powerful battery pack 01 MOBILE MACHINES CUSTOM-FABRICATED TUBES From component manufacturer to service provider: The companies in the Stauff Group and their autho- rised system partners follow this principle to offer machine and plant engineering companies the following services for the processing of tubes, in particular for (but not limited to) mobile and industrial hydraulics: n Automatically controlled and monitored bending of seamless precision tubes made of regular steel (Zistaplex®, Zista® Seal, galvanised, phosphated, untreated), stainless steel, copper and various special-purpose materials in all common metric tube diameters and wall thicknesses, up to 6 m long n Automatically controlled and monitored assembly of cutting rings and union nuts n Tube end forming with Stauff Form and other common systems n Inductive soldering, Cu hard soldering as well as WIG, MIG and MAG for welding non-positive connections n Testing in line with standards or customer specifications n Cleaning of lines to achieve specific cleanliness levels and specifications n Sealing and protecting the tube ends and other connections
