Tarpaulin hangar doors are opened and closed employing steel ropes; the door motor is mounted on the top of the door's profile. The drum system, which is attached to the engine, rotates and wraps on the steel ropes, the door inner plates connected to the steel rope overlap each other and fold upwards.
The steel ropes, which are evenly distributed on the door, carry the door weight equally and minimize the load. The door moves as long as the buttons on the panel are pressed continuously when the button is released the door stops, and when the door reaches the upper or lower point, it automatically stops.
Frame Components of Telescopic Hangar Door:
Components of the frame of Telescopic Hangar Doors should be made of galvanized and coated steel profiles. They should have a modular structure and as such, should be able to be transported to the construction site and installed easily to its place. The EPDM seal system should provide airtightness. Door leaves should be designed to resist against the wind pressure of 1KN/m2, be projected through the manufacturer and submitted to the administration's approval with the static computations thereof. Production of doors should commence after the approval of the administration.
Top Rail Mechanism of the Telescopic Hangar Door:
Top Rail Mechanism of Telescopic Hangar Door should be manufactured from galvanized steel profiles. The rail system should have to direct canals enabling telescopic movement as per the project thereof. Each door wing should consist of at least two sets of upper wheel groups. The wheel groups should prevent the leaves from going off the rails due to the pressure occurring from the effects of impacts or other kinds of pressure. The wheel system should be modular and be changed easily and highly resistant to corrosion.
Mechanism of the lower rail system of the Telescopic Hangar Door:
The lower rail system of the Telescopic Hangar Door should be manufactured from galvanized steel profiles. The rail system should have to carry and directing canals enabling telescopic movement as per the project thereof. The wheel groups should prevent the leaves from going off the rails due to the pressure occurring from the effects of impacts or other kinds of pressure. The canals should not protrude at the bottom and should not cause the shaking of vehicles passing on them. There should be water drain channels in the canal, and they should be able to be cleaned. Each door wing should consist of at least two sets of lower wheel groups. Each set should consist of at least one lower wheel. The wheel system should be modular and be able to be changed easily.
Panels of the Telescopic Hangar Door:
They should be made of 2 pieces of 50mm-thick galvanized steel sheets filled with high-density polyurethane foam. They should have a modular structure and be easy to replace and be changed.
Panel filters should be following the ecological standards and not contain CFC.
There should be hidden isolation seals at the joints of the panels and provide airtightness.
Personnel Door of the Telescopic Hangar Door:
There should be a Personnel Door in appropriate sizes according to the project on the Telescopic Hangar Door.
Illumination windows of the Telescopic Hangar Door:
There should be illumination windows in appropriate sizes according to the project on the Telescopic Hangar Door. The windows should be produced with acrylic insulated glass providing thermal insulation.
Motor System of the Telescopic Hangar Door:
Motor System which will move the leaves of the doors to be manufactured as telescopic doors and which will stop them at the last point when they are opened. The System should be able to be protected by taking into consideration the limits and working times. The door should have the ability to open completely with a pulse and where desired an "open" and "close," button should control the opening and closing sequence by keeping the button pressed. The Motor system should work with a voltage of 380V and frequency of 50Hz. Door opening and closing speed should be 12m/Min.-15m/ Min. Electricity transmission should
