It is the intention to create a stock of photos illustrating the different purposes and equipment on each machine to explain what it does and how. Click on a picture to see it full size and scroll down the picture to read about the picture details.
Below is the Gopher.
Ex Grant Rail at Scunthorpe GR5110.
Designed for the removal of ballast from under the track without having to take out the track. Mostly used for reballasting work on pointwork..
However can be used in plain line and also for the digging of trenches tight alongside the sleeper ends.
For example on excavating under a set of points 1 run would be made down each side followed by a 3rd or 4th cut in the vee. Using the turntable to spin round quickly.
The stowed position for the wheel is tight into the machine. Prior to use it is pushed out from the machine clear of the sleeper ends.
The wheel is then lowered into position and cuts the trench alongside the sleeper end and excavates all the spoil.
To speed the work up it is sometimes better to have the trench dug out by another machine such as a road railer with a small trenching bucket.
Spoil is then dropped onto a short conveyor in the centre of the wheel for disposal.
all the removed ballast or spoil is collected by the buckets in the wheel for removal.
Teeth are removable for replacement when worn.
Side conveyor transfers the spoil from the buckets to the main conveyor.
The conveyor can swing through a fairly wide arc.
