Mount Imbiah Gun Emplacement

The entrance
The Entrance to the Emplacement


Entering the Emplacement. The wall on the left has a small recess in it. This was used to store Firing Tubes for the gun. It originally had a steel door. The two tall, and four other concrete blocks are not part of the Emplacement. They were placed many years ago for a display.


Looking down at the Emplacement. If the concrete blocks were removed, visitors would get a more accurate representation of the Emplacement. Many must think that they formed part of the Emplacement.


Looking down into the Emplacement. In the wall of the Emplacement is a long recessed shelf. On this were stood 30 shells so as to be ready for loading.


The shelf for the shells. In front of the shelf is a filled in area. In here was the front hydraulic shell hoist for the gun. The gun had two hydraulic hoists, the other being behind the breech. In the event of a hydraulic failure, the gun had a davit crane which could be used for loading purposes.


The Holdfast for the gun — 52 bolts sunk deeply into the concrete, onto which the gun mounting was fixed. Running through the ring of bolts was a trench leading to the Hydraulic Accumulator which stored the power to operate the gun and Ammunition Hoists.


Looking from behind the Emplacement. A filled in narrow trench can be seen running towards the Holdfast. This carried communications from the Battery Command Post to the gun.
