A show-stopping system

Since its foundation in 1941 by Master of Science Jan Dellner, Dellner Brakes has been part of the Dellner Group of companies that today has more than 700 employees and production or service offices in all parts of the world. Divided into two major sectors, industrial and rail, the Dellner Group industrial segment is the coming together of three companies within the Dellner Group – Dellner Brakes, Dellner Dampers and Dellner Woodville. These three companies are at the forefront of their fields in brake systems, damper applications and polymer technology.

Having expanded strongly over the last few years, Dellner Brake’s brake systems are used in industries from shipping, offshore, mining, paper, oil and gas and energy.

“We are a small organisation in a big group with a lot of engineering knowledge; because Brakeswe are small and have this expertise we can easily adjust to market demand and find new opportunities. We also use these capabilities to develop strong customer relationships that involve working with customers instead of for them. Customer satisfaction is very important to us,” says Marcus Aberg, CEO of Dellner Brakes.

To be able to deliver solutions to a broad range of demanding sectors, the company has achieved high technical competence, with staff working daily on tasks such as mechanical, electric and hydraulic design, assembly and testing. Small and flexible, the ISO 9001:2008 certified Dellner Brakes benefits from fast decision making and accessibility and is careful when it comes to documenting its systems, progress and unique solutions.

A world leader in marine applications, the Swedish firm develops, manufactures, markets and maintains brake solutions for both the industrial and marine industries. Proud to deliver reliable and cost-efficient turnkey solutions, the company is able to use different combinations of its own standard products to ensure customer satisfaction to owners/operators of a comprehensive range of vessel types. Within the marine industry, the company’s products are used in large military ships, oil tankers, freight ships, ferries, luxury yachts and luxury liners.

“I would say around 50 per cent of our entire revenue comes from the marine industry and we have delivered brakes to almost every type of vessel. Within the marine industry we are working around the propulsion shaft and specialise in making custom size brake systems, locking systems, and turning systems; we call this STL (Stop Turn and Lock),”comments Marcus. “The first STL system we made wasn’t actually for the marine industry, however, we took the knowledge from that specific project and used it in the marine industry. This knowledge has been developed over the years and we are now on the fifth generation of the STL system; we will soon be launching a new generation of the system, which will be lighter, tighter, stronger and more usable than the ones currently on the market.”

Since the introduction of Generation 1 in 2002, STL has been developed and enhanced over the years; it also quickly changed the world market for industrial and marine locking systems. Offering one or several of three functions, all of which are contained in one customer interface, STL includes stopping, in which Dellner Brakes’ hydraulic or electric disc brake calipers effectively handle the stopping operation; turning, where mechanical linkages with hydraulic cylinders or electric motors position the disc brakes, and, together with an intelligent control system, the shaft is turned or indexed without the need of other turning devices. Last but not least is locking, in which the device LM has a specially designed tapered pawl that is engaged into the machined slot on the outer peripheral of the brake disc; this locks the shaft into place mechanically. This device can be operated manually, hydraulically or electronically.

Features of STL include a robust and maintenance friendly system, a range of different friction materials for the varied requirements of customers, remote and/or local operation, fully automatic push button availability and lock-out maintenance functions. “When you buy a three-function propulsion shaft from Dellner Brakes you are effectively buying a system that saves a lot of time” says Marcus. “This is a major advantage for our customers; alongside these benefits we take care of the installation and the customer then has a product that can stop, turn and lock all in one.”

With innovation at the core of Dellner Brakes’ activities, the company is soon to launch the newly developed STL system, which is based on ther knowledge of working with this technology for more then one decade. Features of the product within the stopping process include faster directional changes and maneuverability as well as less load on propulsion systems, while features on the turning process include hydrodynamic bearing conditioning while in port; a reduction in marine growth on shafts, stern seals, propellers and hubs and optimised propeller blade positioning while sailing (sail, twin screw). Improved features of the locking function include reduced fuel consumption during feathering while sailing, less load on propulsion systems, lock-out maintenance function and personal safety, with equipment and environmental protection.

“This new generation of the STL system will be launched at SMM, however, we are already working on the seventh generation of the system, which will be launched at some point in the near future,” says Marcus.

While the company focuses on enhancing its highly respected system and seeks out opportunities to expand its broad customer base at exhibitions such as SMM. It also has a number of developments in the pipeline for both the marine industry and the industrial market. It would appear that no one is putting the brakes on this successful company any time soon.
