Coal Mining Machinery at Work, 1940-1990. Nice look at some of the face machinery used during those years cutting coal...

A bit more history, some I'm guilty of, but once the days of 550 volts were done with, no, stuck by the book, although I've never poked around inside a GEB with door open and power on, nor would I ever consider opening the bus bar/isolator chamber with power on, even at 550 volts or less, way too dangerous. Never touched the pins sticking out of an HT armoured cable without doing the final check either, long screwdriver check!! 11Kv scared me even more, even though we had HV testers and voltage proximity testers, same thing, big screwdriver check, screwdrivers can be replaced.

I remember watching this as an apprentice, indeed I was included in a future video on fault finding which included Clive Ostcliffe from Manvers Training Centre. I see Bob Northcliffe in the video along with the latter electrical engineer at Bilstorpe Colliery (Ernie ??). Bob went on to be a Mechanical Engineer |

When I worked at Angus Place on Oz, we had a new face installation from LW8 onwards, the old gear was Wecols A67's, the new face had CMA, Australian made GEB's modeled on the B&F designs.
One of our elecs put out a waring after the first week of operations, he didn't know whay he did it, just a 6th sense probably, but he had a fault and tracked it down to something in the "suitcase", isolated and opened the door, but before proceeding further, he checked with his proximty voltage detector and he had all the LED's list, there was one phase live. He promptly tripped power at the transformers. What he found was a faulty test switch inside the isolator chamber.
CMA were notified and changed out all the test switches with a different brand.
The proximity voltage testers we used were certified Canadian made "Ezescans" a lifesaver we were all issued with and instructed to use them EVERY time.

Clive, one of our members used to lease that mine, he ran it with his wife, she looked after the paperwork and he cut the coal. He gave up in the end due to lack of willing workers. He sent me photos of the workings many years back, I'm pretty sure I posted them, BUT, they were on Photobucket, and that company got too greedy and I cancelled my account with them. |
