Auxiliary closing device for a motor-powered sealing sliding gate

摘要

The upper gate section 4b of a sealing sliding gate carries a rotatable and connected extension arm 9, the free end of which is steered along the gate's steering rail 5 by means of a steering wheel. At the free end of the extension arm 9, there is a spring-loaded or a line-tensioning arm 14, which can be turned. The auxiliary closing line 18 has its free end connected to the tensioning arm's 14 free end. The auxiliary line 18 is connected to the line pulley 7 on which a lifting line 6 for the gate is wound. The auxiliary line 18 is wound on the line pulley 7 in the opposite direction from the lifting line 6. When the line pulley 7 rotates for unwinding the lifting line 6 the auxiliary line 18 is rolled in and it initiates the gate's closing movements. IMAGE
