South Crofty Mine Robinson’s Engine House 3, this page contains images all taken on the upper floor of the engine house, or to give it the correct name “The Bob Loft”.
Taken with a wide angle lens this shows the Bob loft, the beam is in the centre of the image, the stairs leading down to the middle chamber are on the right.
The great beam of the engine, this alone weighs 38 tons.
The door in the weatherboarding leads out onto the Bob platform.
This is why Engine Houses were built to last, the whole weight of the beam is concentrated on this balance point, directly onto the stonework of the Bob wall.
The balance point of the beam, it is an amazing example of Cornish engineering.
The balance point looking inwards at the “Indoor” end of the beam.
A detailed image of the balance point arrangement, the whole weight of the beam is concentrated here.
The ornate balance point, this is where the beam pivoted, the reservoir infront would have been filled with oil.
Looking up above the beam into the roof area.
When I last saw this the beam was covered in a thick coating of grease to protect it, all this has been cleaned off.
A detailed image of the indoor end of the beam.
Looking down towards the top of the piston which is attached to the beam.
This is the indoor end of the beam, some of the weight is supported by the timber frame resting on iron uprights in the floor.
The external housing of a large hand winch attached to the floor.
It still has the original chains, this would have been used for maintenance on the beam and engine.
This image is taken looking through the beam to the floor below.
Outside Robinson’s Engine house, this was taken on the bob platform. The outside of the beam is pointing towards the headframe over New Cook’s Kitchen Shaft of South Crofty Mine.
The makers name in raised lettering on Robinson’s Engine beam, “SANDYS VIVIAN & CO, HAYLE 1854”.
Looking up at the sheave wheels on top of the 77ft high steel headframe over the shaft.
Many thanks go to Lizi O’Hara for arranging this for me.
