Sperry Rail’s Chief Operating Officer explains how actuators supplied by Olsen help them to retain their status as the world’s leading rail health solutions provider.
In a new video produced by Olsen Actuation, Sperry Rail’s Chief Operating Officer Alastair Veitch, discusses how customised Exlar Actuators, supplied by Olsen, have dramatically improved the accuracy and lifespan of the company’s pioneering ultra-sonic positioning signal, used to inspect railway tracks for irregularities.
In the video, shot onsite at Sperry Rail’s Derbyshire HQ, Alastair explains that since the first rail floor detector vehicle was invented by Dr Emler Sperry in 1927, actuators have always played an important part in positioning and regulating the detector.
However, as modern trains have advanced, so too has the demand for greater accuracy and precision and it is here, Alastair explains, that the traditional ball screw actuators, used on Sperry trains for years, began to experience difficulties.
As the leading rail safety company across Europe and Asia, Sperry Rail trains operate in some of the most challenging rail conditions in the world and are required to retain maximum precision and accuracy across hundreds of kilometres per day.
According to Alistair, the hazardous locations and challenging terrain that Sperry trains are required to operate in proved to be too demanding for their existing ball screw actuators, which soon began to fail, resulting in a disappointing performance and unsatisfied customers.
Fortunately, Olsen Actuators were able to supply a complete packaged solution which not only included 500 advanced Exlar roller-screw actuators, customised to Sperry’s unique application but also the drives, software technology, complete installation and dedicated support by the Olsen Engineering team.
Due to their innovative roller screw design, the customised Exlar actuators that were fitted to all Sperry trains, proved to be far more accurate and repeatable than their ball screw predecessors, while the product’s rugged, robust design dramatically reduced maintenance requirements.
Speaking about the project’s success, Alastair said:
“Out of the five years that we’ve been working with Olsen and out of between 5-600 actuators [in the field], we haven’t had a single one fail. In China we run from -40°c to +60°c in the space of a day! It’s a very hostile environment that these actuators are working in and they’re absolutely brilliant.”
When asked about his experience working with Olsen’s Managing Director Piers Olsen, Alastair had nothing but positive feedback:
“I came to Piers with the problem and he really supported us through it… it’s the relationship that’s the key. Any time that we have a problem we get an answer, we aren’t left hanging around waiting which is good because we can’t afford to. They do what they say, they deliver a quality product and they’re prepared to adapt and help you meet your end goal”.
