- Summary
- BFI synopsis: Vibrating platform which ensures that tubs are filled to capacity (shot at Whitwick colliery)
NCB Commentary - At Coalville’s Whitwick Colliery large-scale reorganisation has been changing the shape of the pithead, increasing output and putting manpower to more productive use.
Among novel installations at the surface are on automatic weighbridge which gives a continuous total of the coal being wound, and an automatic tippler which needs no operator.
Among improvements underground is a Butterley vibrating platform installed at a loading point. In the factory the mechanism of the vibrator is made accessible. The idea is to increase the arrying capacity of tubs and mine-cars by shaking them as they are loaded, causing the coal to settle down while filling takes place.
Underground at the loading point, here’s the platform in action. Before the vibrator was installed tubs were piled high with coal, of which a lot could be spilt before it reached pit-bottom. To-day, ven filling of the tubs means that they can be used to full capacity with no risk of spillage. With the vibrator temporarily stopped and started, see how the heaped-up coal shakes down into the tub instead of off onto the road.
An extra 7 1/2% of coal is being cleared from this loading point since the vibrating platforms were installed. Improvements like this at Whitwick have raised the colliery output into the 50 cwt. per man shift class. - Researcher Comments
