Company insight
The total package for braking systems
With over 1,000 employees operating in more than 30 locations across the globe, Dellner Bubenzer is a world leader in the design and manufacture of braking systems for the material handling; crane & hoist; container handling; mining; marine; industrial; offshore; oil & gas; and wind energy sectors.
aunched in 2021, Dellner Bubenzer united Dellner Brakes JHS, Dellner Brakes, Dellner Industrial, Pintsch Bubenzer and Rima into a single entity. Even today, the company continues to grow and strengthen its portfolio – most recently acquiring a Denmark-based hydraulics company operating in the mining and wind energy sectors. Dellner Bubenzer offers a variety of products for the mining industry, for both above-ground and underground operations, providing braking systems for conveyor belts among other things, which can be a delicate balance to operate effectively. The challenge, then, is find a way to stop the belt without damaging the gearbox or bearings, or indeed, the belt itself.
L
requirements, as well as the company’s global service network, and it adds up to total package that is hard to beat. By way of example, Hoffmans cites the work Dellner Bubenzer has carried out at a copper mine in Mongolia, supplying brakes for three gearless conveyor systems with an installed capacity of two 5,500kW each capable of handling 7,100 tonnes per hour. The brakes can stop the conveyor within ten seconds in loaded or unloaded condition. Depending on the parameters, the hydraulic power unit (HPU) and control unit can provide different braking levels and scenarios. The controlled braking process minimises the conveyor belt tension and reduces stresses in the connected equipment – the system is also able to
“Dellner Bubenzer offers a variety of products for the mining industry, for both above-ground and underground operations.”
“That is [why] we supply our systems with fully electronic devices to brake within a certain amount of time – which is very adjustable,” explains Daniel Hoffmans, global sales director Asia at Dellner Bubenzer. The company supplies similar products for winch systems designed to lower equipment into mining shafts, while also providing hydraulic cylinders for a variety of mining machinery, such as bucket-wheel excavators. Dellner Bubenzer also supplies its brakes through motor companies like ABB and Siemens, further extending its reach into the market. Beyond this, the company also provides a wide range of monitoring devices and controls from simple models to quite exclusive ones. Combine this with the in-house knowledge with which Dellner Bubenzer can fulfil all of its customers’

perform any pre-programmed ramps and stopping curves after a power outage. Dellner Bubenzer also manufactures hydraulic cylinders capable of being used on the biggest serial-produced wheel loaders in the world, possessing built-in solutions to prevent dust from entering the cylinders or the hydraulic system itself. The company’s Hydratech division offer longer service intervals and service time compared with its competitors, while understanding the specific environment and the stress its products will be exposed to in real life. It also manufactures hydraulic units, filtrations systems, accumulators and more.
All about the service For Hoffmans, however, what sets the company apart from its competitors isn’t one simple product or offering. “It’s not
only that we have a fine product, but it’s that we provide the total package – that we provide a certain kind of quality beyond the break itself,” he notes. Critically, Hoffmans sees the company’s service network as the true element that helps set it apart from its competitors. “Our service department is located in Germany – they are the centre of everything,” Hoffmans notes. Beyond that, the company has service centres in Malaysia, Singapore, China, the Netherlands, the US, South America and Dubai, truly covering a huge swathe of the globe. From there, Dellner Bubenzer can send its staff out to offshore or remote sites in order to support its customers. On top of that, the company also provides online support. Dellner Bubenzer also conducts its own internal training sessions at its training academy, guaranteeing that its technicians around the world are up to date with the latest knowledge of its brakes – they even have their own classification, with four levels of official accreditation. The company also offers training services for its customers, to familiarise their staff with its systems and how best to operate and maintain them. “That’s why we have created a four- level system,” Hoffmans explains. For customers, training their staff to a level one or two accreditation would more then suffice for their general needs – for some of Dellner Bubenzer’s more complex systems, however, its own technicians have been trained to level three or four, enabling them to go around the world and ensure that the systems can be installed, conditions maintained and troubleshooting issues addressed, whatever the challenge. ●
