1. Belt conveyor for transport of persons, containing an alighting platform and a device protecting the belt conveyor with transport of persons, characterized in that the alighting platform is installed opposite the course of the belt (3), whose horizontal landing (1) is situated by a drop drum (2), while lengthwise beams (7) connected to vertical shaped sections (6) by a protruding end on the conveyor side are supported detachably on its supporting structure (8), and hand-rails (9), rounded on the belt side (3), pass to a vertical position forming vertical props (10) connected below to the supporting structure (8) of the belt conveyor, whereas the protecting device consists of photoelectric relays (24, 25, 26 and 27) forming the first "light gate", these being connected to a locking unit (22) and installed at a distance equal to three times the length of the overrun of the belt (3), where relays (24 and 26) are installed at a significant height, and relays (25 and 27) are installed at a small height above the belt (3) and shifted in the direction of movement of the belt (3) with respect to a vertical plane passing through relays (24 and 26), and photoelectric relays (28, 29, 30, 31) forming the second "light gate", which are connected to a locking unit (23) and installed at a distance equal to 1.5 times the length of the overrun of the belt, where relays (28 and 30) are installed at a significant height, and relays (29 and 31) are installed at a small height above the belt (3) and shifted in the direction of movement of the belt (3) with respect to a vertical plane passing through relays (28 and 30),...<IMAGE>
