34 Pa. Code § 7.285 - Control apparatus
(a)
Types. Permissible types of control for freight elevators are
as follows:
(1)
New
installations. The controlling mechanism of all new freight elevators
shall be restricted to such types as car switch, automatic, double-button
control, wheel or lever (hydraulic).
(2)
Existing installations.
Existing power-driven elevators operated by rope or cables shall have
manually-operated landing doors or gates equipped with approved electric
interlocks. In such instances, the requirements of subsection (b) of this
section and §§
7.283(b) and
7.296(d)
(relating to safety requirements; belted and silent chain drive elevators). In
hydraulic elevators that are operated by hand-cable control, the gates shall be
made manually closeable and equipped with approved type
interlocks.
(b)
Electric control switches. Electric car control switches
shall be so designed and installed in new cars that, upon removal of the hand
of the operator, the switch will automatically return to the "off" position.
Low voltage and no voltage protection shall be provided on all new electric
elevators so that the elevator car will not restart upon the restoration of
voltage or service until the operator has first moved the controller to the
"off" position. Low voltage and no voltage protection shall be provided for
existing hand rope control elevators having electric brakes, so that the
elevator car will not restart upon the restoration of voltage or service until
the operator has first moved the control to the "off" position.
