1.1
Scope.This document establishes a standard for the design,
manufacture, construction, operation and maintenance of the passenger Tramways
in the State of Colorado. For this standard, passenger Tramways include:
(1) Aerial Tramways (single and double
reversible).
(2) Aerial lifts
(detachable lifts, chair lifts, and similar equipment).
(3) Surface lifts (T-bar lifts, J-bar lifts,
platter lifts, and similar equipment).
(4) Tows (wire and fiber rope
tows).
(5) Funiculars.
(6) Conveyor lifts.
These rules and regulations are promulgated by the Colorado
Passenger Tramway Safety Board pursuant to the authority conferred by section
12-150-101
et
seq., C.R.S., as amended.
1.2
Purpose. The purpose of this
standard is to develop a system of principles, specifications, and performance
criteria that will meet the following objectives:
(1) Reflect the current state of the art of
Tramway design, operation, maintenance, and construction It is recognized that
certain dangers and risks are inherent in machines of this type and their
operation. It is also recognized that inherent and other risks or dangers exist
for those who are in the process of approaching, loading, unloading and
departing from passenger Tramways. This system is intended to result in
Tramways that are designed, constructed, operated, and maintained in a manner
that helps reduce danger and exposure to risk to passengers and maintenance and
operational personnel and to encourage improvements in productivity,
efficiency, development, and progress consistent with the objectives. Such a
system with these stated objectives constitutes a safety standard.
1.2.3
Exceptions. Strict
application of the provisions of this standard may not be appropriate in every
instance. Wherever it may be proposed to depart from the provisions of this
standard, the authority having jurisdiction may grant exceptions from the
literal requirements or permit the use of other devices or methods that provide
features comparable to those included in this standard, providing that after
receiving such evidence as the Board may require, the Board determines that:
(a) The granting of such an exception would
be consistent with, and would aid in, implementing the legislative policy set
forth in section
12-150-101, C.R.S., and,
either;
(b) Compliance with
applicable rules and regulations from which an exception is sought would create
an unreasonable operational or design condition; or
(c) Compliance with applicable rules and
regulations from which an exception is sought would create an unreasonable
economic burden.
1.2.4.1
Existing installations. Existing tramways, when reinstalled, shall
be classified as new installations (see 1.2.4.2). For tramways that have not
been relocated, but have not had routine maintenance performed within the
previous two years or longer, these tramways shall be subject to an acceptance
inspection and test as outlined in 2.1.1.11, 3.1.1.11, 4.1.1.11, 5.1.1.11,
6.1.1.11, 7.1.1.11 (ANSI B77.1) and 2.1.1.11 (ANSI B77.2) Acceptance Inspection
and Tests. This test and inspection shall verify that the tramway is in
compliance with the rules and regulations that were in effect at the time the
tramway was originally constructed and current rules that affect all tramways.
A tramway modification or alteration shall be defined by 21.1 and meet the
requirements of 21.3, 21.4, and 21.5.
If an ANSI B77.1 or CPTSB rule was in existence at the time
of the ropeway installation date or modification date of an existing tramway
and is absent from the current CPTSB rules and regulations, it shall continue
to be required.
For electrical drive or control modifications performed on
tramways installed prior to April 15, 2019, the requirements of ANSI B77.1-2011
shall be met (Refer to Annex R).
1.2.4.2
Relocated installations.
Existing ropeways, when removed and reinstalled, shall be classified as new
installations. New installations which have not received their initial
registration by the effective date of these rules and regulations shall meet
the requirements in effect at the time of initial registration (See
21.1.1).
1.2.4.3
New
installations. New installations which have not received their initial
registration by the effective date of these rules and regulations shall meet
the requirements in effect at the time of initial registration (See
21.1.1).
1.2.4.4
Major
tramway modification. A major tramway modification shall be defined as
an alteration of the current design of the tramway which results in (See
21.1.2):
(a) A change in the design speed of
the system;
(b) A change in the
rated capacity by changing the number of carriers, spacing of carriers, or load
capacity of carriers;
(c) A change
in the path of the rope;
(d) Any
change in the type of brakes and/or backstop devices or components
thereof;
(e) A change in the
structural arrangements;
(f) A
change in power or type of prime mover or auxiliary engine;
(g) A change to control system
logic.
1.2.5
Interpretation of Rules and Regulations. Additional explanation or
interpretation of these rules and regulations shall be the responsibility and
at the reasonable discretion of the Board. An appeal to the ruling of the Board
may be made in conformance with section
24-4-106, C.R.S.
1.2.6
Existing Laws or
Ordinances. This standard shall be considered as supplementary to any
existing law or ordinance covering the installation or operation of these
facilities. All construction shall be in accordance with applicable codes of
the state or its political subdivisions and the codes and standards of the
industry.
