Schneider ammunition wagon for 75mm QF guns

The ammunition wagon of the Schneider 75 mm field gun was composed by the limber and the caisson. It was drawn by a team of six horses, like the gun. Both the limber and the caisson were made entirely of steel, except for the poles and the wheels that were of wood with tyres and naves of steel. The U-turn angle of the ammunition wagon was 70°, that of the gun was 72°.

The limber was composed by the chest, the axle with two wheels, two swingletrees, the pole, a knapsack-rack with grid to carry the cannoners equipment, and miscellaneous hardware. It had both spring draught-loops and a spring limber hook. It was seated for three gunners. Beyond 38 rounds, it contained tools and spare parts.

The caisson was made like a tip-cart, so that it could be tilted into a vertical position beside the gun. This entailed carrying the ammunition vertically when travelling. The bottom of the wagon body was armoured and the bullets-proof doors opened outwards, giving a wide protected area for the three men who were employed in preparing and supplying ammunition. The steel has the same thickness as the gun-shield, namely 4.75 mm for the Bulgarian wagon. The caisson was composed by the chest, the shaft, the axle with two wheels, the brake mechanism, the support for the fuzes and miscellaneous hardware.

Each projectile was contained in a separate tube of bronze fixed in the ammunition box. In order to admit a quick handling, the ammunition was carried in horizontal position. The mechanical fuze-setting machine was carried on the caisson. An armoured observatory was carried on one of the ammunition wagons.
