FIELD: construction.
SUBSTANCE: industrial door comprises lamellas, end parts connected to them, and a driving mechanism connected to end parts to ensure lifting and lowering of the specified rollover door, holes provided in lamellas and located at least at their one remote end and passing towards the lamellas, and safety devices interacting with application of friction forces arranged with the possibility of sliding release from the specified holes. End parts are made with the possibility of displacement in a direction parallel to lamellas length, in response to a force applied substantially perpendicularly to lamellas. The industrial door comprising lamellas, end parts connected to them, and a driving mechanism connected to end parts to ensure lifting and lowering of the specified rollover door, holes provided in lamellas and located at least at their one remote end and passing towards the lamellas, and safety devices interacting with application of friction forces arranged with the possibility of sliding release from the specified holes, and end parts are made with the possibility of displacement in a direction parallel to lamellas length, in response to a force applied substantially perpendicularly to lamellas.
EFFECT: invention will make it possible to prevent damage of the industrial door in case of impact exposure.
