Switch Points GFSU-700-m

Point device is used to move the point from one position to another by which it secures reliable blocking of the point and keeping the tongue rail in end position. Possible malfunction or failure of the point device is indicated on the control panel in the station room. Switching equipment is used for fixing, connecting and transmission between point device and switch point.

  • 4 wire control with control voltage of 60 V
  • Device can be cut and it is reversible
  • Device has the possibility of manual power with a starter in case of power failure
  • Adjustable lever stroke with possibility of adjusting switch throw (150- 170mm)
  • Throwing stroke is 220mm, throwing time (for 220mm) is 3.0–3.9 sec., transfer relation is 1:7, trailing resistance is Ft ≤ 11000N, retention force is Fr = 7000N
  • Point device GFSU-700-m: engine power 3×400V, 50Hz, power 0,55kW, n = 1280 rpm, 4-pole engine, throwing force 5500N ± 10%, throwing current I = ≤ 2A under voltage of 400 V a.c. 50Hz
  • Device housing provides IP54 protection
  • Weight of switch point device is 165 kg
  • Housing equipped with the key no. 1
  • Switching equipment enables mounting on all rail types


A derailer is used to prevent unwanted entrance of the rail vehicle from side track to the main track or it’s unauthorized movement. It has strong steal construction of sloped rib and setter. A slope is placed above the rail that pushes the wheel of the coming vehicle off the track, which is less harmful than letting the vehicle drive in the wrong direction or track. They are made as left IS-L and right IS-D derailers. Derailers can be placed manually or by switch point adjusted to the derailer power.
