Drives for oar gate of H20

In a design of the drive the new layout decision is used. With which in the Case the electric motor and the first step of a reducer is placed are not movably fixed on colon of an aperture of gate (similarly lever drives). The second step of a reducer (a running shaft and the running plug) are located in the separate case which is sharnirno connected to the motionless case. Rotation is transmitted to the running screw and the running plug through worm and conic transfers.
Use of new configuration, allowed to increase movement of the running plug to 370 mm for H20/3 series drives …, and to 550 mm for H20/5 series drives... Also new configuration and increase in movement of the running plug, allowed to displace a point of fastening of a forward arm further from a loop. It gives the chance to increase the moment developed by the drive for movement of a shutter and to provide the angle of opening of a shutter to 120 ⁰.
The system of fastening of the drive to an aperture allowed to pass to completely hidden conducting.
