“Great company to work with, efficient and professional in their approach. Attention to detail and technical expertise readily available to complete the job to a high standard, would highly recommend!”
The Situation
A relationship that has spanned over 5 years, SDS have supported Big Pit National Coal Museum with parts and engineering consultation since 2017. Located in Blaenavon, South Wales, Big Pit is one of Britain’s leading mining museums. As part of the experience, guests can travel 300ft below ground using the specially designed winder system that allows the cages to travel the shaft.
Once underground the quests are given an exclusive tour by an ex-miner where they navigate the old roadways and gaining an appreciation for life as a collier in coal mining. Our most recent project for the National Coal Museum involved supporting this very system.
Even though Big Pit is no longer a working coal mine it still comes under the current mining regulations and is governed by the mine’s inspectorate. The system that we developed had to be fit for purpose, meet the current safety requirements for man riding and conform to all current standard regulations.
The museum is operational 7 days a week, 362 days a year so we had an allocated timeframe, with a challenging environment to contend with.
The Solution
The drive control that operates the winder that lowers the cage needed updating as parts were now obsolete and the ever-growing need for energy efficient systems. The client required a system that was fit for purpose: to support the weight of the visitors and lower them at a set speed into the coal mine. The technology they used prior to our visit was becoming obsolete and spare parts were becoming difficult to source. Having been in place since 1952, hence why the system required review and modernising.
