Safety Features
Safety Arms and Platform Ramps
While in motion, the platform is protected by two safety arms. The platform is
also protected by two ramps which have the dual function of facilitating access
to the lift at the landings and of retaining the wheelchair while the lift is in
motion. Before the lift leaves the floor, the safety arms must be down and the
platform access ramps must be up. If the safety arms or platform ramps
encounter an obstacle as they move into position, a microswitch is tripped,
preventing operation of the lift until the obstacle is removed.
Obstruction Sensors
During travel, the edges of the platform ramp and carriage are protected by
sensors which stop the lift if it touches any obstacle. There are also safety
underpan sensors to detect any obstacle underneath the platform and carriage
and stop the lift.
Safety Brake (Overspeed)
The lift is equipped with a mechanical safety brake. It engages if a drive
component fails or if the normal downward travel speed is exceeded by a
preset amount. Application of the brake slows the lift to a stop.
When the safety brake engages, the lift remains locked
out of use. Contact your authorized dealer to release the
brake and return the lift to normal operation.
Limit Switches
The upper and lower limit switches allow the lift to stop automatically in the
correct position at the upper or lower end of the staircase. If the upper or lower
limit switch fails, the final safety limit switch stops the unit.
If the lift is unable to move after it stops, contact your
authorized dealer to return the lift to normal operation.
Audio Visual Alarm
There is an audio visual alarm to indicate that the unit is running. This includes
a buzzer and a red running light on the platform control panel that flashes
when the unit is in use. See Figure 4 on page 7.
