The hangar platform slides on six guide pillars, and is equipped with a second rotating platform to range and correct the wrong helicopter position after landing. It can work with two different mechanisms: the mechanical activation and the oil pressure activation.
The mechanical activation is granted by a series of gear and counterweights activated by a single electrical engine, thanks to the counterweight system that reduces the load and allows the saving of the energy.
The oil pressure activation is granted by ram pistons inserted in every column, all of these activated by a pump.
The platform covers slide on proper fixed rails, activated by electrical engines or hydraulic pistons. The covers are totally isolated and made of rubber against any bump.
The EMIP underground hangar can work by means of phone commands or by a removable control panel.
It is possible to prepare the take off with a simple message, making the covers open and the platform rise
After the take off the whole platform closes in within few minutes.
For the landing another message is enough: The platform opens again and the guiding light turns on.
After the landing and the ranging of the helicopter, a simple message will make the platform lower and close the covers.
