Molycop manufacture wheels for Rolling Stock in their Mayfield (NSW, Aus) based Rail Products, Edge Water Mill.
The site produces the steel in an Electric Arc Furnace & ingots are cut, then forged to a Rail Wheel.
The Mill then rolls the wheel to the predefined size & shape, ahead of final machining.
This is a highly competitive environment, given the consumption of wheels across our land mass and the magnitude of Mining.
A very tight window for the complete overhaul & modernisation of just 2 weeks was required.
K&R’s project team procured, pre-planned, pre-engineered & pre-machined every component in order to meet the tight window.
The Cylinders, originally installed in the mid 1930’s – running on high pressure water, were converted to Oil Hydraulics in the 60’s.
As such, they are a design with a “liner” in the bore & used copper & leather for sealing, with some major components heavily eroded.
The two Carriage Cylinders, 8” Bore, 6” Rod & 95” (2.4m) Stroke, were completely overhauled, modernised & tested within the time frame. The before & after photos give an insight to the external change but the real work was internal, where we:
- Replaced the lining bore sleeves using our 500 tonne horizontal press.
- Modified the gland to enable fitting of the Modernised Sealing Arrangement
- Machined & reclaimed porous & water eroded end caps
- Performed Cycle testing
“Thankyou K&R. The Cylinders arrived this morning and are going in now. They look really good. Very nice work.
Hopefully they run as good as they look. I reckon they might have dropped out of the “top 10 ugliest cylinders” list, into the Top 10 Prettiest!
