ELECTRIC SWITCH MECHANISM SP-6BM
The electric switch mechanism SP-6BM is designed for switching, closure and position control of railway points with undivided throw of switch blades at sections of metro railways.
The electric switch mechanism SP-6BM is designed for switching, closure and position control of railway points with undivided throw of switch blades at sections of metro railways.
The electric switch mechanism ensures tight abutment of a switch blade to a stock rail at the extreme positions and does not allow for switch to be locked at clearance of 4 mm and more between the adpressed switch blade and the stock rail and retracts the other switch blade from the stock rail to the minimum distance of gate stroke. A gear with a metal-ceramic friction is used in the design.
