SECTIONAL DOORS POWERING

Electromechanical powering of the spring balanced doors.

Powering made by a motorgear 400 – 240 V threephased, 50 – 60 Hz, that is applied onto the shaft of the balancing springs, for mechanizing the opening and closing of the door. The motorgear has different powers and dimensions, depending from the door weight.
Doors above 3 x 3 meters are almost always mechanized by a motorgear that is installed onto the balancement spring shaft . The powering by a motorgear has the big problem of the overlapping of the ropes and consequent rupture at the next lifting: this occurs when the door is closed against a leveller still in position onto the truckbed, typical of the midday pause. This happens because the closing of the motorgear continues until the reach of the dock height (because of the end-of-run microswitch). The motorgear wants to reach the closed position of the door, that stops earlier against the still connected leveller.
