On our Railway Tamper an Accumulator is fitted.
When we bought the tamper it had been in place for about 20 years.
The Insurance man said it would be best if we could fit a new one, this we did brand new from a supplier near Leeds.
That was 3 years ago, a fortnight ago when wrapping up the tamper after a shift, the hydraulics seemed slow, on checking we found the Accumulator was empty.
Contacted the supplier and after checking it was found that the rubber bag in the cylinder had split.
This was a factory supplied item with no involvement from us.
