Mechanical Lift Analysis
When the lifts were first utilized, the latch solenoid overheated. (It was repaired by enlarging the
lock cavity in the jamb to provide more air space.) In addition, the cable,which restricts the
vertical movement of the lift, would initially jump the track until additional lubrication was provided.
Service for the lifts at this location is only provided from the manufacturer's headquarters in
California.
The lifts have been installed for three years. Building maintenance receives a schedule on each
Friday for courtroom use during the following week. (If it is anticipated that lift operation
will be required, it will be highlighted on the court schedule.) The lifts are then tested prior
to use.
Key control of the lift operation can provide some challenges, and it was questioned
whether a keyed operation is really necessary. (Typically the building manager and the
Clerk of Courts retain a key, but there is a potential situation that no key will be available
when the lift operation is required.)
When this lift is not in operation, which is more than 95 percent of the time, the witness box floor
level is in the suspended position (one step up from the courtroom well floor level.) The
hydraulic system is in operation, under pressure, all of this time. It is apparent that loss of
pressure within the hydraulic system will be more prevalent because of this condition. It
would be more practical to provide retractable struts that would sustain the pressure at the suspended
position and allow hydraulic pressure to be released for the non-operational period.
Gaps between the lift platform and adjacent fixed floor level edges are less than 3/4 IN.
Removable stairs (two risers) are used when accessibility for the disabled is not an issue.
(The stair element is heavy and awkward to remove.)
Vibration and equipment noise are noticeable, but not of a high magnitude. Stability is not an
issue.
A metal edge molding is used around the perimeter of the platform; and carpet at the fixed floor
level edges is turned down into the pit.
Gates are well integrated into the millwork of both the witness box and judge's bench.
