The gear rack drives switch rails to unlock, change the position from N to R or R to N and lock the switch at the end of the stroke.Low voltage.DC supplies 24 volt DC.High voltage DC supplies -110V DC.High voltage AC 380 AC.
![]() Hw Points Hine Series Split FieldDC series split field motor within built in reduction gear unit 2. To avoid voltage drop in cable cross section. Contact of lever knobpush button do not have the heavy duty current carrying capacity. Over-current sensing isolates the motor if a foreign object jams the points. The screw assembly is fitted with limit switches and there is separate electrical detection of the locks. Five pairs of fixing holes allow the machine to be bolted to sleepers of wildly varying spacing. The throw bar is double-ended, allowing the machine to be used on right or left handed points. A second drive may be attached to work a back drive, or trap points. There is a facility to allow the machine to be manually driven using a crank handle. Power to the motor is cut when the crank handle is inserted. A separate switch rail detector can be added by using a common alignment plate. The BR998 detector is ideal for this purpose, but other designs can be used. The open construction of the chassis allows the easy replacement of all components.
