Switch operating gear set serves to move blades of asymmetric pointwork and comprises working and control tie rods, foundation angles, four adapter connection angles with vertical and horizontal flanges. Foundation angles have holes for attachment to frame rails. Adapter connection angle fitted on bent frame rail, on blade tip side, features arrangement of fastening bolt holes that allows attaching said angle to frame rail on right or left switch at right or left location of the drive. Location of said holes made earlier will be changed. ^ EFFECT: lower labour input, faster attachment. ^ 2 cl, 1 dwg |
