DEVICE FOR THE CONTACTLESS DETECTION OF THE POSITION OF A WINDING DRUM OF A SERVICE DOOR WITH FLEXIBLE CURTAIN
The device for the contactless detection of the position of a winding drum (2) of a service door according to the present application consists of a cam or code wheel (3) secured to said winding drum (2), inductive sensors (4, 5) positioned close to said cam or code wheel (3), and an electronic card (7) comprising at least one prevention and security module (12) receiving the pulses generated by the inductive sensors (4, 5) in order to ensure the security of the rotation control of the drive shaft of the winding drum (2) of the service door.
Retaining device with elastic deformation for a flexible screen of a vertically-opening goods handling door. The vertically-opening goods handling door according to the present invention comprises an elastic retaining device (10) which consists of retaining means (11) allowing, firstly, the flexible screen or curtain (12) to be held on course during its movement between an open position and a closed position and, secondly, in the event of an anomaly, allowing the flexible screen or curtain (12) some elastic deformation without the risk of said flexible screen or curtain (12) being expelled or dislocated from the lateral uprights (13, 14) and ensuring that it reverts to its initial form when the anomaly disappears.
