Cal. Code Regs. Tit. 8, § 3065 - Car and Counterweight Safeties
(a) If a car safety is provided, it shall
engage the guide rails to produce a retarding force, and it shall conform to
the requirements of Section
3035 and the following:
(1) The safety shall be of a type which can
be released only by moving the car in the up direction. The switches required
by Section 3036(d) shall,
when opened, remove power from the driving machine motor and control valves
before or at the time of application of the safety.
(b) If a plunger engaging safety device
(PESD) is provided in direct plunger hydraulic elevators, it shall engage the
plunger to produce a retarding force, and it shall be designed and approved for
that purpose. See Section
3106.1 for required approval data.
(1) The PESD shall:
(A) be the type that can only be released by
establishing at least no load pressure on the hydraulic system,
(B) be responsive to a pressure decrease in
the system,
(C) be field
testable,
(D) be field tested
during the acceptance test. The test shall be witnessed by the Division before
a permit to operate is issued. The test shall be conducted at no less than the
operating speed in the down direction with a capacity load on the car, to
demonstrate that the PESD shall stop the elevator with its capacity
load.
(2) Further, the
PESD shall:
(A) be tested annually for proper
operation with no load,
(B) when
actuated, operate a switch that shall cut off the power from the operating
valves and pump motor. This switch shall reset only upon release of the
PESD.
(3) The PESD shall
have a metal plate or plates, permanently attached and readily visible, marked
with legible and permanent letters and figures not less than ¼ inch high
indicating the following:
(A) the name of the
PESD manufacturer and the identifying numbers,
(B) the date the PESD was initially tested
and witnessed,
(C) the diameter and
wall thickness of the plunger for which the PESD is designed,
(D) the maximum weight, in pounds, for which
the PESD is designed,
(E) the
maximum speed for which the PESD is designed, and,
(F) the shim adjustment
range.
(4) The PESD may
be used on new elevators that are covered by regulations in Group III and
existing elevators that are covered by regulations in Group II.
(5) The runby clearance may be reduced to no
less than one inch on existing hydraulic elevators if a PESD is
provided.
