   Sind an der Halle mehrere Tore in einer Reihe angeordnet, so dass die Pfeiler zwischen ihnen sich befinden, dann sind sowohl die Windevorrichtungen für beide Tore, als auch deren   Antrieb, die Zahnräder   und die Gegengwichte gemeinschaftlich zwischen den Pfeilern 3 gelagert. 



  Zur besonderen Sicherung gegen Herabfallen der Torteile können noch an den Pfeilern Zahnstangen angeordnet sein, in die an den Torteilen befestigte Sperrklinken beim Hochkurbeln einschnappen. 



  Es können auch Fangvorrichtungen vorhanden sein, die sich gegen die Pfeiler legen, wenn die Torteile beim Bruch eines Getriebeteiles niederfallen wollen.

   If several gates are arranged in a row in the hall, so that the pillars are between them, then both the winch devices for both gates and their drive, the gears and the counterweights are jointly stored between the pillars 3.



  To prevent the gate parts from falling down, racks can also be arranged on the pillars, into which pawls attached to the gate parts snap into place when the gate parts are raised.



  There may also be safety devices that lie against the pillars if the gate parts want to fall down when a gear part breaks.
