Requirement
A manufacturer and operator of high-speed
passenger trains for the U.S. market needed
an internal door assembly with advanced
passenger detection and anti-entrapment
features. The system had to be controllable
so door speed and the force required to
open it could be set to meet ADA and
other regulatory standards. It had to fit the
customer's design footprint and meet their
low weight requirements. To control the
motion of this door assembly, they needed
a compact, lightweight actuator that was
reliable and easy to maintain.
Solution
IMI Precision Engineering designed a
lightweight aluminum electric actuator
with a programmable controller. Opening
speed and force can be set to meet
customer requirements. The system detects
obstructions and locks the door open in case
of power failure. The actuator's light weight
helps reduce the energy required to start and
stop the train. Its compact design facilitates
installation in spaces restricted by HVAC
piping, electrical cables or other obstacles.
The door system is manufactured in Littleton,
Colorado, under the Buy America provision
of the American Recovery and
Reinvestment Act.
