That's what our customers say about ALTO

„In planning matters ALTO consulted us very well and executed our demands for workshops, diverse parking spaces and sliding walls without any problems. The new hangar simply looks great."

Klaus Blankenagel, President of Luftsportgruppe Menden e.V.

„My flight mates and myself consider ALTO's solution of aircraft hangar carousels ingeniously simple and efficient. In no time I can all by my self pull my aircraft out of the hangar. Hangarage after landing is done just as quickly, all of this without help and free of damage."

Heinrich Schäffler, Pilot

„Our first ALTO hangar proved to be very good, so we ordered the same hangar again five years later."

ALTO Aircraft Hangar Carousel

The ALTO innovative aircraft hangar carousel, especially developed for the aviation industry, rotates a large circular floor space inside a hangar. The aircrafts are parked on the hangar carousel or pushed off from it into a hangar corner.

This system relocates any desired aircraft in the hangar in door position within less than two minutes at maximum, without the necessity to touch any other aircraft. While our standard decks are 24m in Ø for GA aircraft up to 1,5t MTOW and 30m Ø for business jets with MTOW’s of 10t, we can offer these platforms in any size and for any loads.

The system is controlled by a switch, control panel or remote control and rotates into both directions. Our unique below-floor multiple engine drive guarantees smooth starts, fast turning and precise stops. We offer various configurations and optional equipment to choose from.

The system is in use on more than 80 airports and airfields throughout Central Europe.

These are the benefits:

These are the details:

basic steel construction, depth according to size and load

wooden surface deck, anti-slip and impervious to all aircraft fluids

motors and castors virtually maintenance free
