Dellner Brakes is launching a brand new range of ‘plug and play’ electrohydraulic braking systems at this year’s SMM in Hamburg, Germany, combining the very best of Swedish and German engineering, from Dellner Brakes and sister company Pintsch Bubenzer, for the very first time.
The new BUEL STL systems provide a compact, self-contained solution for stopping, turning and locking ship propeller shafts on vessels of all sizes, as well as for industrial applications.
They are the first to combine groundbreaking technologies from Swedish-based Dellner Brakes and their new sister company, Germany’s Pintsch Bubenzer, which the Dellner Group acquired in January this year.
As the name suggests, the systems combine elements from Dellner Brakes’ innovative stopping, turning and locking (STL) systems with Pintsch Bubenzer’s patented BUEL electrohydraulic thruster / power package.
Needing no external piping, the systems are compact, easy to install and, with the BUEL using only half a litre of high-performance synthetic oil (compared to 7l of hydraulic oil in standard hydraulic power units), are cheaper to run and environmentally friendly too.
Dellner Brakes CEO Marcus Aberg said: “The new BUEL STL is the perfect solution for customers looking for a high-performance, self-contained braking system that’s simple to fit and operate.
“It brings together the very best of Swedish engineering excellence and German production quality for the benefit of our customers, and we are confident this will be the first of many co-operations between Dellner Brakes and Pintsch Bubenzer. We are very much looking forward to showcasing this exciting new product at SMM, as part of our full portfolio of brakes and clutches for the marine industry.”
Pintsch Bubenzer CEO Markus Topp said: “The development of this new product clearly shows the synergies that can be gained by combining our two companies’ expertise and a collaborative approach to product development.
“With strong environmental credentials, especially when combined with Dellner’s locking and turning devices, this product is also perfect for a world where environmental concerns are sure to remain high on the agenda.”
At its simplest, the new system combines a Pintsch Bubenzer BUEL Model G with a powerful Dellner disc brake. Customers can then choose to add a Dellner locking device and, for a full STL system, a Dellner electrical continuous turning device. The stopping, turning and locking functions can be operated individually or as a fully automated system.
Dellner Brakes’ STL systems fit around the ship propeller shaft to enable faster directional changes with maximum manoeuvrability. They also help lower fuel consumption, reduce load on propulsion systems, and make routine maintenance quicker, easier and safer.
Securing the propeller prevents damage to the shaft and bearings if the vessel is drifting or buffeted by waves. It also allows ROVs and divers to operate around the propeller blades in safety. When in harbour, using the turning function to rotate the propeller can also help to reduce marine growth on the blades and lubricated shaft bearings.
More information about the BUEL STL, including 3D hologram projections, are available on Dellner’s stand at SMM stand number 101, Hall A4. Dellner is showcasing the BUEL STL as part of their overall portfolio of products for the marine market, including their full electrical STL system for small to medium-sized vessels and the Dellner Gummi USA FKT marine clutch. Pintsch Bubenzer, on their own stand number 403 in Hall B6, will also be showing their SFB motor mounted brake, which is used for winch motors in shipbuilding and as safety and service brakes in wharf crane installations.
