Steam Cranes Cow Patch - West Tilbury marshes

Does anyone have any photo’s or memories relating to the old cranes that were situated on the river edge over at the ‘Cow Patch’ (West Tilbury marshes). I think they were probably the cranes that off-loaded the waste from the ships when the Cow Patch was still an active dump? The Jetty is still there with the rail lines the cranes moved along still in place. The Jetty can be seen on Google maps about half a mile west of the Coalhouse Fort radar tower.
