driven by a closed-loop digital- feedback VVVF drive,
controlled with a 32-bit microprocessor that communicates
with all the elevator equipment using CANbus serial
communications. These implementations save about 50%
of the energy conventional systems use. The passenger
elevators have also been equipped with an automatic
emergency-rescue device in the case of power failure.
In addition to all safeties being provided as per EN 81
standards, an enhanced safety feature in the form of a
rope brake was installed in the passenger elevators. This
rope brake will operate by clamping the ropes in the
event of loss of traction between the main drive sheave
and the main hoist ropes of the elevator.
The 3000-kg, 1-mps, geared passenger and freight elevators
follow similar features as those of the passenger
elevators, with the exception of the larger cabin size of
2.3 m wide, 2.6 m deep and 2.5 m high. The door opening
measures 2 m wide and 2.4 m high and has standard
stainless-steel hairline finish cabin and door panels.
In an endeavor to enhance the elevator performance,
Concord Elevator provided high-intensity, cast-nylon
deflector sheaves, car looping sheaves and counterweight
CANbus serial communicating control
