After having seen it from somewhere near the centre of Chedder, I picked my way through a number of residential roads and finally found the access road. Expecting a fairly long uphill walk, I was surprised I could drive right up to the gates.
I parked up a little way down the road and walked up to check out access, then promptly hid when I saw the 50' concrete tower with 3 CCTV cameras pointing at the two bottom entrances, but given the rest of the site I wasn't just going to leave it at that.
On finding a way through into the site, I came up beside the tower, and found none were covering the back of the site, so onto the photos :)
There were three main structures left on site, one fixed gib crane mounted on the quarry wall, a "mobile" rail mounted rotary crane, and a normal fixed tower.
The mobile crane was made up of a triangular base, each corner with wheels on, and the crane body mounted on the outside corner, supported back to the other legs.
As this took all the load off to one side, this was used to counterbalance it.
The site also contained a number of buildings that look like they were for admin, training or just workshops, but these had been stripped and had evidence of being done up.
Some had tools and equipment left inside, but I have no idea how recently they were used.
