1. Redesigning of the framework of a deep vertical-lift gate by replacing the multibeam framework by a two-beam and the four-support system by a three-support makes it possible to dispense with grooves in the lower part of the walls of the opening and to eliminate off-design loads in the framework and supports, which increases the operating reliability of the proposed type of regulating gate with increased load-bearing capacity and heads. 2. To increase the load-bearing capacity of the slide supports and their life, to reduce the calculated coefficient of sliding friction, and to eliminate irreversible plastic deformations in the antifriction element from local overloads, it is expedient instead of the traditional supports transferring the load by linear contact of the antifriction slide with the rail to use two-level supports with a deformation compensator of the gate framework. Such supports have contact with the embedded parts along a plane.
