Mechanical Lift Analysis
Raising the platform is accomplished by push button control, either from inside or from outside
the witness box, with the gate closed. (Operation is smooth and not quiet.)
Similarly, lowering the platform is accomplished in the same manner. (Operation is generally
smooth, with a slight scraping noise near the end of the travel cycle. There is also a slight
popping noise from the pump whenever the cycle is initiated. It is possible to stop and start during a
The platform is level, rigid, and stable, plus it does not flex when loaded.
JUDGE'S BENCH LIFT:
The second unit provides accessibility for the judge's bench. It is accommodated within
a room approximately 4 FT-2 IN wide by 4 FT-6 N deep, adjacent to the courtroom, accessible off the
the ante-room serving the secure corridor and judges chambers. (The platform is approximately
3 FT-2 IN wide by 4 FT-0 IN deep.)
A pair of 3 FT-6 IN wide doors, interconnect to prevent opening both at the same time, provide
upper and lower access to the lift.
Clearances between the platform and doorways is approximately 1/2 IN along the front and back.
When the access doors are closed, there is approximately a 1-1/2 IN space between the raised
platform and the lower door.
There is a mechanism to prevent operating the lift when the doors are open, and also a control
to prevent opening the doors when the platform is in operation.
The anteroom access doors have strikes near the top that engage when the platform is in
operation. There are metal rods that project horizontally from these strikes and engage small
diameter holes cut into the doors. It appears that these rods serve the function of accessing
and overriding the mechanism from outside the room in case of a mechanical failure
Raising or lowering the platform is accomplished by holding in a button, either from the
platform or from outside the access doors. (Operation is generally smooth, but is very noisy.)
It is not possible to stop and start the lift during a travel cycle. If travel is interrupted, it must
be resumed in the opposite direction.
