MECHANICAL OPERATION

1. Drive Mechanism

A reversible ac motor [A] drives the LCT'S bottom plate up and down.
The motor's drive is transmitted directly to the tray drive shaft [B] via a worm
gear and worm wheel. The tray wires [C] have braces on them; these braces
hold the ends of the two lift rods which support the tray bottom plate. The
braces on the wires raise the lift rods [D] and the tray bottom plate when the
pulley turns counterclockwise, and they lower them when the pulley turns
clockwise.
