FIELD: construction.
SUBSTANCE: balancing device for vertical-lift gate comprises springing element, traction element and reeling device. One end of springing element is arranged with the possibility of fixation on floor. Traction element with its one end is fixed on springing element, and with its other end - on reeling device. Reeling device is arranged with the possibility of connection to drive of vertical-lift gate. Traction element is arranged with the possibility of winding onto reeling device and unwinding from it so that springing element is stretched to the maximum, when wing of vertical-lift gate is in closed position, and is substantially unloaded, when wing is in open position. End of traction element facing winding device has lower width compared to end that faces springing element. Winding device comprises shaft and guide device installed on it, which may be used to wind traction element so that layers of roll do not touch each other. Guide device for this purpose has guide surfaces on the side of periphery with radius that smoothly increases in direction of winding.
EFFECT: balancing of torsion torques.
