The invention relates to a safety device for a lift gate (1), in particular a fast-running lift gate (1), having a flap (3) which moves up and down and is guided along the edge of a side door opening on both sides of a frame (10), the free leading edge (12) of said flap (3) being provided to an optoelectronic barrier (LS) at a distance (D) below said leading edge (12), the photoelectric barrier (LS) moves along with the movement of the gate leaf (3). Wherein the distance (D) can be reduced in the region of the lower end of the movement path of the gate leaf (3), and wherein at least one transmitting and/or receiving unit and/or an opposite reflector unit in the optoelectronic barrier (LS) is guided and/or arranged in a frame body (11) of the frame (10). 本发明涉及一种升降闸门(1)的安全装置，特别是一种快速运行的升降闸门(1)，该升降闸门(1)具有沿框架(10)两侧的侧门开口边缘进行上下移动和导向的门叶(3)，在所述前缘(12)下方距离(D)处将所述门叶(3)的自由前缘(12)设置到光电屏障(LS)，所述光电屏障(LS)随所述门叶(3)的移动进行移动。其中，可以在所述门叶(3)的移动路径的下端区域中减小所述距离(D)，并且其中，所述光电屏障(LS)中的至少一个发送和/或接收单元和/或相对的反射器单元被导向和/或设置在所述框架(10)的框架本体(11)内。
