Golvet som öppnades upp automatiskt och tömde ner judarna i krematoriet i Auschwitz

[...] they undressed, men and women separately, in dressing rooms, handed over their belongings, and then went to a room on which it was written 'Bath'; there, they were killed with high-voltage current. The floor then opened, and the corpses fell onto the conveyor belts slowly moving to the furnaces, where they were burned[.]

Last year, when the Red Army revealed the terrible and disgusting secrets of Majdanek to the entire world, the Germans in Auschwitz began to wipe out the traces of their crimes. [...] They [...] blew up and destroyed the traces of the electric conveyor belt where hundreds of people had been simultaneously killed with electric current; the corpses fell onto the slow-moving conveyor belt and were carried by it to the shaft furnace, where they were completely burned[.]

[...] the gas chambers were equipped like bath houses, and [...] the people allegedly were to take a shower in them, that gas came out of the pipes instead of water, and that later the floors were tipped up, causing the victims to fall onto a conveyor belt, which transported them to the crematorium.

The victims fell down stunned; some died immediately, others came to, and were taken living to the flames. The floor then opened, and the bodies fell onto trolleys which were already ready, and the people were dumped into furnaces heated with wood.

Two thousand people were herded into a large hall, of course undressed, with soaps and towels. Then gas came out of the nozzles. After the gas killed the people, the automatic floor started to move and it threw the bodies into the oven underneath. That was a circle-shaped floor, which could be divided into two mechanically.

[i]f there were many transports and they had to burn a lot of people at the same time and had no time for gassing them the floor simply turned and people fell in the fire alive. The floor had an invisible metal axis, which was made to function by electricity. The switch was pushed by an SS man who stayed close in a cabin, from within a small adjacent cabin. If he pushed one of the switches the floor turned in an upright position and the victims slid on a conveyor belt that was invisible before, which carried them into the crematorium.

Once the gassing process had been completed, the floor of the chamber opened automatically and the corpses fell into the subterranean chamber[.]

The inside of this chamber looks like a very large bathroom. There were objects similar to showers and there was a very pretty tiled floor. In the floor there were trap doors which opened. Under these were truck containers and the bodies after gassing were dropped into them to be moved to the furnace where the bodies were burnt. The iron trap doors were covered with tiles and there were benches all around. I saw all this.

And from the boilers the gaseous steam is conducted through the pipes, the boilers are red, and the steam... a hellish boiling bath. Four minutes suffice, then the floor flap automatically drops down, and the slimy mass of red, curled bodies flows away into the cesspit. And finished, the pits are simply filled with chlorine, and there is no more trace of what was once alive.

They were asphyxiated with chlorine. After 15 minutes, they had all suffocated. Through a window it was checked whether they were all dead. Then the floor opened automatically. The corpses fell into the cars of a train passing through the gas chamber and taking the corpses to the oven.

A German, who was called the 'bathhouse attendant,' looked through a small glass opening on the roof to see if the killing process was completed. Upon his signal, the gas was shut off, the floor was mechanically drawn apart, and the corpses fell below. There were carts in the cellar, and a group of doomed men piled the corpses of the executed onto them.

The 'bath' keeper observes the whole procedure through a window in the ceiling. Within a quarter of an hour everything is over. The floor opens and the corpses fall into carts waiting below, in the basement of the 'bath-house'. As soon as they are full, they move away quickly. It is all done according to the latest German technology.

There was a gas chamber which could hold 600 persons; the gas came into the chamber through showers; once the people were dead, the floor opened up and they fell through.

And he was the one who ordered the victims in their final agony and in their death. At his order the machinery which opened the floor of the 'bathhouse' was activated, and the corpses fell into small carts, which took them at first to mass graves and later, when time was short, to cremation ovens instead.

After some time, a buzzing sound would be heard, the floor opened up, and the victims fell into the deep hollow below and were conveyed in this little train into the pit where the eighty men of Camp 3 were working, and they burned the bodies.

[...] trap doors were located in the gas chambers through which the corpses would fall.

Once the Jews were all inside, the floor of this hall sank like a lift into a great tank of water which lay below it until the Jews were up to their waists in water. Then a powerful electric current was sent into the metal flooring and within a few seconds all the Jews, thousands at a time, were dead. The metal flooring then rose again and the water drained away. The corpses of the slaughtered Jews were now heaped all over the floor. A different current was then switched on and the metal flooring rapidly became red hot, so that the corpses were incinerated as in a crematorium and only ash was left.

The floor was then tipped up and the ashes slid out into prepared receptacles. The smoke of the process was carried away by great factory chimneys.

When the bath house is completely full with 100-120 people, gas and high-voltage electric current are fed into it. Within 5 minutes, all the people in the bath house were dead. Inside the shed, the floor folds automatically, and the corpses fall into a previously dug trench where the victims are doused with a flammable liquid and burnt.

From this I conclude that the hinges were used for the floor of the gas chamber, which opened up after the Jews had been killed, thereby letting the corpses drop into carts, which took them to a common grave.
