CONSOLIDATED SURVEY & SITE VISIT INFORMATION:
The most significant characteristics of the lifts at this facility are the shapes of the platforms.
The challenges related to incorporation of these shapes has been the instability of the ride. The
framework of the platform and the mechanism used to raise the lift were not adequately reconfigured
from the standard rectangular shape to compensate for the irregular loading forces. Original
factory fabricated perimeter reinforcing flanges had to be removed and platforms field modified
due to insufficeint coordination with the millwork enclosure. (Reinforcement was accomplished by a
local welder hired by the supplier.)
Maintenance items on these units have included: leaking check valves and hydraulic hose;
ineffective gate latch contacts; a faulty height-limit switch; plus too much tolerance at the bearings
and track on the height limit cable control. (Scheduling of service on all of these items was a
challenge.)
The pit is deep enough to provide direct access from the courtroom well level without a short ramp.
Equipment access panel has carpet applied with no frame and the edges are frayed.
