INITIAL STATEMENT OF REASONS


INFORMATIVE DIGEST OF PROPOSED ACTION

The informative digest contains occupational safety and health regulations which are building standards for codification in Title 24, Part 7, California Elevator Safety Code. The building standards, herein, will be identified by their Title 24 section number in italic type following the corresponding Title 8 informative digest.

Article 9. Hydraulic Elevators
Section 3065. Car and Counterweight Safeties.
Section 3065(a)

Existing Section 3065(a) specifies that car safeties, where provided, shall conform to the requirements of Section 3035 and that the safety shall be of a type which can be released only by moving the car in the up direction.

Proposed Section 3065(a) will allow hydraulic elevator owners the option of providing elevator car safety devices provided they produce retarding force and comply with the requirements of Section 3035 and Sections 3065(a)(1).
Title 24, Part 7, Section 7-3065(a)

New Section 3065(a)(1)
Proposed new Section 3065(a)(1) is a redesignation of existing Sections 3065(a) and (b). All of the requirements in existing Sections 3065(a) and (b) are retained in proposed new Section 3065(a)(1).
Title 24, Part 7, Section 7-3065(a)(1)

Section 3065(b)

Proposed Section 3065(b) will specify that if a PESD is provided on a direct plunger hydraulic elevator, it shall engage the plunger to produce a retarding force, and it shall be designed and approved for that purpose. This Section will reference Section 3106.1 for required PESD approval data.

Proposed Section 3065(b) will, in effect, permit owners of direct plunger hydraulic elevators to provide a PESD on direct plunger hydraulic elevators if it is the type that engages the plunger to produce a retarding force, and if the device is designed and approved for that purpose. Further, elevator owners choosing to provide a PESD shall provide one that complies with the requirements of proposed new Sections 3065(b)(1)(A) – 3065(b)(6).

The test shall be witnessed by the Division before a permit to operate will be issued.
Title 24, Part 7, Section 7-3065(b)1.D.

New Section 3065(b)(2)(A)
Proposed new Section 3065(b)(2)(A) will require the PESD to be annually tested for proper operation with no load.

New Section 3065(b)(2)(B)
Proposed new Section 3065(b)(2)(B) will require that the PESD, when actuated, operate a switch that shall cut off the power from the operating valves and pump motor. The switch shall reset only upon release of the PESD.
Title 24, Part 7, Section 7-3065(b)2.B.

New Section 3065(b)(3)

New Section 3065(b)(5)
Proposed new Section 3065(b)(5) will permit owners of existing hydraulic elevators to reduce the runby clearance from existing runby requirements when the PESD is provided.
Title 24, Part 7, Section 7-3065(b)5.

Section 3065(b)(6)
Proposed Section 3065(b)(6) will permit owners of hydraulic elevators to forgo the 5-year load test per Section 3071(j) when a PESD that complies with the requirements of Section 3065(b) is provided.

Proposed new Section 3106.1(a) explains that the purpose of the PESD is to prevent uncontrolled descent due to loss of pressure on direct plunger hydraulic elevators. This section will require that when a PESD is provided, it shall comply with the following requirements:
(1) When the PESD is actuated, the forces applied to the plunger shall be compressive and distributed over the circumference of the plunger. This force shall not exceed 28% of the plunger yield stress.
(2) Supports for the PESD shall be capable of withstanding a kinetic force of 115% of the total load stopping with a deceleration of 1 g.
(3) The PESD shall:
(A) actuate when there is a loss of hydraulic pressure that could cause the elevator to go into an out-of-control descent,
(B) not release the plunger if there is downward motion of the plunger,
(C) be fully operational during a primary electrical system power failure, and
(D) have sufficient running clearance between the gripping surface and the plunger to not adversely affect the plunger or the gripping surface.
(4) The PESD bearings, when used, shall be corrosion resistant.
(5) Parts of the PESD and supports, except springs, shall have a safety factor no less than 3.5. The materials used shall have an elongation of not less than 15% in length of 2 inches. Forged, cast or welded parts shall be stress relieved. Roller chains, if provided, shall comply with ASME B29.1M-1993. Wire rope, if provided, shall comply with Section 3107.
Title 24, Part 7, Section 7-3106.1(a)

New Section 3106.1(b) Data Required for Approval.
New Section 3106.1(b) will require owners of direct plunger hydraulic elevators to submit the following data to the Division for approval of the PESD if it is used on direct plunger hydraulic elevators:
(1) Two complete sets of detail drawings showing the assembly of the PESD. The drawings shall indicate not less than the following:
(A) The construction of the PESD and the dimensions of major parts.
(B) The shim adjustment range indicated on the marking plates required by Section 3065(b)(3).
(C) Indication of how the clamping surfaces are held in the released position.
(2) Results of performance tests conducted by the manufacturer or approved testing laboratory. The results shall indicate the device functioned satisfactorily within the range of loads and speeds for which the device is to be approved.
Title 24, Part 7, Section 7-3106.1(b)

New Section 3106.1(c) Performance Tests Required for PESD Approval.
Proposed new Section 3106.1 (c) will require owners of direct plunger hydraulic elevators that provide a PESD to submit the following test results to the Division:
(1) Tests to indicate the surfaces subjected to friction by the PESD will not reduce the usual life expectancy of such surfaces.
(2) Tests to indicate the gripping mechanism of the PESD does not adversely affect the plunger.
