Description
1. 5102 NZ 36 NE 12/89
TROW POINT Trow Rock Floating Platform
II
2. Casing of Clarke Maxim Disappearing Platform, for 6-inch breech-loading gun. 1887 for the Inspector General of Fortifications, for experimental trial purposes. Mass concrete. Cylindrical shape of approx. 21 feet internal diameter with west extension for approach tunnel. Rough-shuttered exterior. Interior shows runners for steel floating platform (now removed) and entrance to tunnel. Structure is sunk deeply into the ground to accommodate the water upon which the platform rose and fell, actuated by air pressure pumps, and is now largely filled with earth.
Historical note: Trials of platform took place on 15th and 16th December 1887. It was found that the raising and lowering of the platform was too slow and the system was abandoned in favour of the quicker and cheaper Elswick hydro-pneumatic mounting.
Of historical interest as a relic of late C19 artillery development experiments.
