UNISTAR HR EM Point Machine

The UNISTAR HR EM point machine is an electro-mechanic point machine for freight, urban and mixed traffic.

The electro-mechanic UNISTAR HR EM is used in the field of grooved rail turnouts. Due to its compact design the locking unit can be installed between the gauges for gauges starting with 1435 mm. For smaller gauges, the installation takes place next to the track
The connecting rods compensate for thermal expansion and contraction of the switch points without affecting the end position adjustments. Motor voltage can be ad-justed from 110 to 550 V AC or DC.

UNISTAR HR EM is part of the UNISTAR HR series which also includes:
