The first slip ring which we developed for use in a winch application was what is known today as our TX4702. Ordered in August 1982 by our customer Expro North Sea, the unit comprised of 8 rings and was given a Baseefa Certificate of Conformity No Ex 821417 to comply with BS5501: Part 1: 1977 EN50 014 and BS 5501: Part 5: 1977 EN50 018, in January 1983.
Initially called product 475, the product became the TX4700 Series in February 1988, and maintains that today. The product has a cast aluminum housing for use in rugged environments and is certified for both ATEX and IECEx applications.
Since this initial development, thousands of the units have been sold worldwide and continue to do so. For further information about the TX4700 Series, please click here.
Drawn and produced in early-1978 by Steve Rogers and Jim Parkinson, our first slip ring was a 100/9. This pioneered Flameproof Electrical Slip Rings for pedestal cranes and was for our customer, National Supply. As the name suggests, the unit contained 9 rings, rated at 660V max, 100 Amps max. It received its Baseefa Certificate of Assurance No. Ex 79032 and Ex 78251 in September 1978, and complied with the requirements of BS 5501: Part 5: 1977 (EN 50.018) in respect of Group IIB and Temperature Class T6.
This Slip Ring was drawn, manufactured, assembled, certified and delivered by Steve and Jim, and this hands-on knowledge is an important part of our heritage.
This unit was returned to us in 2012 for refurbishment, whilst the crane was on shutdown, and is back in service today!
Our history began in 1975 in a shed less than 5 miles from our current location, where our company, originally Engineering Design Services, designed and produced a staircase and fittings for the house of Mr. Johnson, working with our customer Booker Fitzgerald. Obviously, this isn’t the product which we produce today; the first Slip Ring we developed was for use on a children’s ride and was designed and manufactured by the founder, Jim Parkinson.
In 1976, Engineering Design Services were introduced to Trolex Ltd. Initially drawing flameproof enclosures, before quickly expanding into manufacturing, this relationship developed and later saw us adopt their name, becoming Trolex Engineering.
During 1977, with our knowledge of flameproof equipment established, Steve Rogers joined the company and we made our venture into oil and gas exploration; pioneering the design, manufacture, assembly, certification and delivery of the first flameproof electrical Slip Ring for use on a pedestal crane, for our customer National Supply. This Slip Ring was returned to us for refurbishment in 2014 and is still in service and fully operational today!
This month marks the 40th anniversary of the founding of Trolex Engineering. We have grown to become a leading company in our industry with over 30 employees, supplying to 49 countries worldwide.
40 years is a great achievement. It provides the opportunity to look back and reflect, but to also look forward to the future. A key element of our success, and one that we pride ourselves on, is our relationships with all stakeholders, appreciating the impact they have on our business. Our company started as an independent British manufacturer and maintains that today. This milestone proves the reliability of our products, even when operating in some of the most extreme environments around the World.
To celebrate this achievement, we want to share our history, our present-day and our future with you. This will be done in a series of short stories over the next 12 months on our website.
Without our customers none of these stories would have been possible, so thank you for your support and we look forward to another 40 years!
Trolex Engineering have successfully passed their LRQA ISO9001:2008 Certificate Renewal which took place in December 2014, validating our system for a further 3 years!
ISO9001 (published by ISO – International Organisation for Standardisation) is a global quality management system designed to help organisations ensure that they meet the needs of customers and other stakeholders whilst meeting statutory and regulatory requirements. It covers all areas of the business including:
Following a 2-day audit of our quality systems, the LRQA Auditor had some great things to say about our company, such as:
“No non-conformances or problems with any of the system – could easily work towards the updated standards which are released later this year as we already do many of the things that contribute to the new standards.”
“Great company to audit – I wish all were like this”
“Quality records are readily available and production systems were reviewed as impressive.”
Trolex Engineering has held ISO9001 status since 1 March 1991 and remains committed to the ongoing optimization of our systems and processes in support of business objectives. The recognition of our efforts to be a high-quality company is great to see from external auditors.
