<p>#CMT# #/CMT# The shutter (1) has a set of lamellas (2-4) formed by an armor plate (14) and guided in door frames (12) by rollers e.g. ball bearing-nylon rollers, at ends (8-10) of the lamellas. The rollers adjacent to the lamellas are movably guided in guiding webs that are arranged parallel to each other in the frames. The door frames are formed as the rollers from bottom and top receiving housings, and the guiding webs are provided in inner sides of the housings that are formed by metal angles connected with each other. Round bars are intermittently fixed to the door frames. #CMT#USE : #/CMT# Rolling shutter for closing a horizontally extending opening in a building e.g. service or workshop pit. #CMT#ADVANTAGE : #/CMT# The rollers adjacent to the lamellas are movably guided in the guiding webs that are arranged parallel to each other in the door frames, thus enabling effectively closing the horizontal running opening in the building with high stability to receive heavy loads of people and equipment. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a top perspective view of a rolling shutter for closing a horizontally extending opening in a building. 1 : Rolling shutter 2-4 : Lamellas 8-10 : Ends of the lamellas 12 : Door frames 14 : Armor plate.</p> |
