MOVABLE ARCHITECTURE

The structure can be open via a hand winch that is connected

to a hydraulic cylinder. The hand winch has a built in delay that

lowers the forces conveyed through the hydraulic cylinder. One

of the eight roof parts only needs one hydraulic cylinder on

one side, the other side is powered by a pressure pump that

helps lifting the structure by compressed air, but can not go up

by itself. The roof is lifted by turning the hand winch, the roof

therefore can be partly opened or completely if wished. Because

of the smooth roof surface the snow can easily slide down when

the structure is being opened. Heavy duty hinges on both sides

of the construction transfer the forces directly on the main

beams of the construction.
