A feat of 19th Century engineering, Tower Bridge is one of London’s favourite icons. Under the Corporation of London (Tower Bridge) Act 1885, the Bridge is required to be raised to provide access to and egress from the Upper Pool of London, day and night, 365 days a year. The Bridge is raised around 800 times per annum.
When the Tower Bridge management team identified a problem with their bascule raise mechanical drives, they called on their controls specialists, Fairfield, who brought in Brevini to assess the situation. With many years of experience in the design and installation of gears and motors, Brevini work closely with Fairfield on a whole range of civil infrastructure projects, including maritime applications such as swing bridges and sluices.
Dana Brevini have launched a new tool to help our customers easily select the appropriate geared motor or geared unit via a configurator accessible from the website.
The configurator provides at-a-glance, detailed technical information across the full range of geared motor products, and customers can set a whole range of parameters to quickly identify the most appropriate product from the Brevini Gearmotor range.
2017 is, arguably, a pivotal year in O&M strategy for the UK wind power industry, with many long-term service contracts reaching the end of their term. Here, Andrew Baggaley, Aftermarket Manager at Dana Brevini UK, considers the elements of gearbox inspection for onshore renewables.
Inspection of sun pinion wear marks
Well-established in the UK, the wind farm sector is now facing a raft of uncertainties, not least the impact of Brexit and relations with the EU – a significant proponent of renewable energy. That said, investment in the UK continues to be strong and the Wind Europe report, ‘Wind in Power, 2016 statistics’, published this month, indicates that the UK was, again, the largest EU investor in wind power, at 46% of total European financing. These trends, combined with the general challenges faced by O&M managers, mean that the consideration of gearboxes – as an integral part of the wind turbine – has never been more pertinent.
The combination of Brevini and Dana Off-Highway creates a formidable player in the market with complementary, advanced technologies
REGGIO EMILIA, Italy, Feb. 2, 2017 – Dana Incorporated (NYSE: DAN) announced that it has completed the acquisition of the power-transmission and fluid power businesses of Brevini Group, S.p.A. The transaction closed yesterday, Feb. 1.
Anyone working in the UK waste water treatment industry will be familiar with the type of problems faced by Yorkshire Water at the Saltend Waste Water Treatment Works, where long-standing issues around odours disturbed the local community, most notably during the peak load season (late June – August), when the flows into the site peak.
Announcing an investment of £30m to address these issues last October1, Yorkshire Water’s improvement works are now complete – with Brevini UK being awarded a contract which sees the Warrington-based company once more working on environmental improvements for the residents of East Yorkshire.2
Removing original drive
For this major project, Brevini were commissioned to work on the Morgan Sindall Sweco joint venture, specifically to replace the original EIMCO rake drive system in the lamella tanks – a significant part of the whole waste water treatment plant at Saltend. With a very tight timescale – Yorkshire Water set a target for major improvements to be operative for summer 2016 – Brevini had only an 8-10 week turnaround, to cover: concept, design, rapid pricing, manufacture and installation on site, for a solution that would interface with existing kit at the plant.

Limited places available for Brevini and NFPC “Stage 2 Winch Hydraulic Systems” training course at NFPC, 7-9th November 2016.
Highly practical, this course is designed for technicians and engineers involved in the maintenance and management of winch systems involving a range of hydraulics and controls, and is ideal for company technical representatives. It is relevant to a range of sectors including: offshore and marine; fishing; dockside, and construction & crane applications.

There are many challenges facing engineers in the mobile and marine sectors, not least of which is the often-complex combination of mechanical and hydraulic systems, with competing priorities of machine performance, and efficiency and cost-effectiveness.
Launch and recovery system
Commonly, the specification of the mechanical components influences the hydraulic requirements, and vice versa. For example, the combination of a gearbox ratio with hydraulic motor displacement gives different flow and pressure requirements. Often, using a higher gear ratio – without any additional cost implications – allows for a reduction in motor size, saving on cost without compromising on performance. Similarly, the control of hydraulics can affect mechanical systems, e.g. where pressure relief settings of pumps and valves need to be set at a level to protect the mechanics. Clearly, a knowledge and appreciation of both areas assists in specifying a safe and efficient system, with optimised performance.
Doubling the capacity of the Panama Canal, the recently-opened expansion has tripled the maximum vessel-size for this major international shipping route. Critical to this huge engineering project are the new locks, the most important component of the expansion, and Brevini gearboxes are driving the massive sluice gates.
One of the completed PD67 Posired 2 gearboxes
With a total of 16 rolling gates to operate the Canal extension, the sluice gates are 30m high, 60m long and 10m wide, each weighing over 4,000 tons, with 2 Brevini gearboxes driving the opening/closing cycle. Brevini faced a number of significant challenges on this project. The gates must be opened in less than 5 minutes, with a 43-minute cycle of opening/closing which is repeated 33 times per day, with only 180 minutes of stoppage permitted per month. With a lifespan requirement of 35 years, the gearboxes need to provide 57,000 hours of operation, working in humid conditions with high levels of salinity. Reliability of function is paramount to this critical application.
For the steel industry it is more important than ever that proper maintenance and repair work be carried out on its plant and equipment to prevent costly and potentially catastrophic failures. Here Andrew Baggaley and Tony Botfield of Brevini UK explain how techniques they have pioneered across several steelworks in the North of England are paying dividends.
Steel making creates some of the harshest working conditions a gearbox may be expected to tolerate. In continuous casting for example, temperatures are extreme with the steel product still red hot and semi-molten when it hits the roll out drives. Add to that a dirty environment, shock-loading and the runtime demands of continuous production, and even purpose-designed gearboxes will require frequent rebuilds. It’s no secret that resources and overheads have been squeezed within the UK steel industry as it strives to remain profitable in the global market. While UK competitiveness stems from a reputation for some of the highest quality product produced anywhere, it is also essential that refurbishment of plant is well managed in order to minimise cost and extend service life.
