Bottom guiding rails. Sleepers and rails, whose installation requires high accuracy, are fastened with studs fixed with chemical anchors. The cable heating system, which automatically maintains positive temperature of the tracks, prevents their freezing to the bottom seal of the hangar doors. Melt water is removed from bottom rails through a special drainage system.

Extra information

  • Operate hangar doors carefully following the instructions of Operation Manual and Technical Data for the hangar doors.
  • Only qualified personnel can install DoorHan hangar doors and must be fully knowledgeable in the design, construction, technical operation of the subject doors according to the corresponding Specifications and Documents. The installation specialists must have electro-technical and mechanical certified qualifications and have knowledge of all technical parameters and safety devices of the doors. They must produce corresponding trade certificates before installation. During the operation and technical maintenance the staff must fulfill all safety requirements as described in the Operation Manual and special instructions.
  • Prior to door operation the operator should:
  • - examine the notes on door maintenance;
  • - examine the door leaves for signs of wear and tear, torn or broken sections of the seal. Special lifting equipment is not required;
  • - inspect bottom rails, remove foreign objects, snow and ice from the path of door movement;
  • - make sure that bottom seals are not frozen to the floor-mounted channels, switch on the heating system if necessary;
  • - inspect rails and stops; make sure the concrete flooring is solid;
  • - make sure there is no maintenance personnel on the bottom or top rails, carrying out maintenance work. Should any maintenance have been done make sure there are no instruments and foreign objects left on the rails;
  • - make sure all the rolling shutters protecting the drive system are lowered or closed;
  • - make sure the passdoor is closed.
  • If the operator detects any failures threatening safe operation of the doors and he can’t eliminate them by himself, the operator, without operating the doors, should report to the responsible person and make an appropriate entry in the log.
  • The operator should not:
  • - transfer control of the doors without permission of the person in charge;
  • - get distracted from his responsibilities;
  • - leave unattended the control unit with the inserted key-mark;
  • - start the reverse movement of the doors prior to their complete stop except when he needs to prevent an accident.
  • After the inspection and corresponding notes to the log are made the operator should switch the power on using a toggle switch located in the hangar and feed the power supply to the door leaves of the chosen door opening.
  • In winter (when outdoor temperature is below zero) the operator should switch the heating system on with a toggle switch located in the hangar.
  • In several seconds needed for the frequency converter to be automatically tested, after the power supply is on an indicator lights up on the control unit signaling the doors are ready to be operated.
  • The operator should constantly press the OPEN or CLOSE button to operate the door. In case he detects any foreign objects on the rails or failures to the door, or a STOP signal sent the operator should release the button to stop the door. Each time the door is stopped during closing the operator should make sure there is tight contact between seals of the neighbouring door leaves and the opening.
  • In case of failure in control, detection of loose contacts (including grounding), appearance of smoke or smell of burning insulation, door operation should be stopped immediately, and power should be switched off with a toggle switch. Operation should not be resumed until the damage has been repaired.
  • One should strictly observe safety regulations during door maintenance, routine inspection, troubleshooting and operation. Staff should be examined for knowledge of safety regulations at least once a year by a special commission. The results of the examination are recorded in a special journal.
  • Description and specification for the component parts (gear motors, control units, etc.) are provided in the corresponding Technical Data (Operation Manual) attached to the Technical Data for hangar doors.
  • Safety bumpers installed on both sides of the door leaves guarantee the door would stop in case it strikes an obstacle of 2.2 m high. Should the door meet an obstacle the safety bumper low pressure switch switches off the gear motors and the door stops. After that the gear motor can move the door only in opposite direction. Once the obstacle is removed the door should be reversed and only after that it can be moved in original direction.
  • Power to the door leaves is supplied with trolley busbars. The busbars are connected from an electric cabinet with a toggler switch installed in the hangar close to the door opening.
  • In case of power outage the door is moved with a winch or a tow tractor which hooks to the retractable trunnions (outdoors) or eyelets (indoors).
  • Each door leaf has its own control cabinet fitted with a frequency converter regulating gear motors start. In case the gear motors need to be mechanically disengaged (to move the doors during power outage) use a disengaging clutch installed on the output shaft of the gear motor. For security reasons niches where gear motors and control cabinets are installed are protected with rolling shutters.
