Dellner launches to US marine market

adminDellner Brakes

Dellner Brakes AB chose the International Workboat Show in New Orleans (30 November to 1 December 2016) to launch its portfolio of technologically advanced braking solutions, including the world’s first fully automated, electrical ‘stop, turn, lock’ (eSTL) system, to the US marine market.

While Swedish-based Dellner Brakes is no stranger to the marine market – their products are fitted in ferries, tugs, oil tankers, large military ships, multipurpose vessels, luxury yachts and cruise liners all over the world1 – their US operation has traditionally focused on the industrial sector, operating through wholly-owned US subsidiary Dellner Industrial Inc. Dellner is now looking to bring its precision made braking systems and expertise to the US marine market and is investing in the expansion of its US team to support this drive.

Glenn Scott, Sales Manager, North America for Dellner industrial Inc. said: “We’ve been operating successfully in the US industrial sector for 25 years and we are now investing to support the expansion of our product offering to the US marine market.“Backed by more than 50 years of innovation, Dellner prides itself on being one of the world’s most creative manufacturers of braking systems and components. We are always looking for new opportunities and we continually adapt everything we do to meet the changing needs of our customers and the markets we operate in.

“It is this flexible, pioneering approach that has seen the development of our unique ‘stopping, turning, locking’ (STL) braking systems and the world’s very first electrical STL, which we are now proud to introduce to the US marine market.”

Electrical STL  a world first

The fully automated, electrical ‘stopping, turning, locking’ (eSTL) braking system, which was launched to the US market at the Workboat Show, is a true world first. This patent pending electrical STL system is compact and needs no additional piping, making it quick, easy and cost effective to install – especially where space is at a premium. It’s simple to use, hard wearing and easy to maintain, and it’s perfect for applications where a clean environment is paramount, for example or for use in green shipping zones.

The system is available in a range of standard sizes but it can also be customised for different applications. The unique, modular ‘stopping, turning, locking’ system allows customers to choose one, two or all three functions to create a bespoke solution for their needs.

Marcus Åberg, CEO for Dellner Brakes AB, said: “Our new eSTL system the latest in a long line of innovative, technically advanced and precision made braking systems that fully complements Dellner’s world beating hydraulic solutions.

“Developed in response to an increasing global focus on environmental issues and a demand for smaller, flexible braking solutions, this groundbreaking electrical system is a world first, offering terrific power in a compact configuration for customers in offshore and onshore industries alike.

“We have held initial discussions with our customers about this new electrical system and we are delighted with the response so far. Our customers tell us that they value the flexibility of Dellner’s STL system, which allows them to pick and choose from the three components to suit their specific needs, and that eSTL will give them even more choice for small and mid-range applications.”

The Dellner eSTL system is fully automated but it can also be operated from an optional remote hand held control, giving operators the freedom to inspect the complete system during maintenance and testing.

Here’s how it works:

  • Stop: A disc brake system stops the shaft quickly in any position.
  • Turn: After the brake has stopped the disc, an electric motor rotates the pinion so it aligns automatically and accurately with the gear wheel on the disc. A second mechanism then engages the pinion with the gear wheel and the electric motor allows the disc and connected shaft to be rotated at a variable speed to any exact position.
  • Lock: An electrically operated mechanical locking system locks the brake disc and shaft safely and securely, even in ship failure modes.

The eSTL also has an optional continuous turning (cT) function that allows the shaft to be moved to any position precisely without the need for indexing. This makes maintenance easier and, as the variable speed motor can run continuously for hours, checking and testing can take place over long periods.

Depending on the size of the system, stopping torque can be up to 900 kNm, turning torque up to 600 kNm and locking torque up to 1,650 kNm. Even Dellner’s small and mid-range eSTL systems can deliver stopping torque up to 300 kNm, turning torque up to 150 kNm and locking torque up to 700 kNm.

World beating braking solutions

Dellner’s pioneering STL braking systems are also available with hydraulic power and as a hybrid version, which combines a hydraulic brake with an electrical ‘continuous turning’ function. The STL systems are precision engineered to facilitate faster directional changes with maximum manoeuvrability for marine vessels. The unique design also contributes to lower fuel consumption, reduces load on the propulsion systems and allows for easy, safe maintenance including hydrodynamic bearing conditioning. As well as STL, Dellner’s SKD disc brakes provide powerful, reliable and safe braking of rotary motion and longer brake life. They are specially designed for use on propulsion propeller shafts or wherever service, stopping, holding or tensioning is needed.

Dellner also supplies a range of locking mechanisms, power packs, brake discs and hubs, all in a range of standard sizes and customisable on request.
