Homelessness implies mobility and by default it is not the main asset of the six shells Bubble. But it was not counting on the wisdom of Jean Benjamin Maneval.

How to move a Bubble 36 m2, length of 9,70m (including stairs), 6,90m wide and 4.20m high with a total weight of about 3500 kg ?

The solution is simple, simply place the Bull six shells on a trailer attached, with wheels, like a caravan. Only shells # 1 and # 4 are fixed on said trailer 4 wheels. Each displacement, it will 2 flatbed, the first with the left side of the bubble, or shells # 2 and # 3, which will also draw the trailer and a second truck that will host the right side of the Bubble, or shells # 5 and # 6.

A special roller carriage will also be created for the occasion, a second fact trailer, it will allow 2 drivers with an additional assistant to ride the bubble to them 3 in very little time.

To install a bubble on said carriage, it is enough to switch over, without lift. The truck has been calculated to match the height of the shell transported with those existing on the trailer.

The installation is so easy. This trailer will be driven by the second truck.

All trucks / trailers can move on roads with a speed of 60 km/h maximum.
When the Bubble six shells is dismantled, 6 bars stand between the shells 1 and # 4 are set, 2 up, 2 middle and 2 below.


Given the commercial function of the Bubble six shells, it was necessary to offer him a large door. On this Bubble six shells Prisunic access will be through one of the windows opens. And particularly that of the hull # 1, located at the rear of the trailer, on which will set off the staircase with 1.80m 7 marches.
A second opening window will be present, it will serve as an emergency exit if the need arose. But without staircase ...
