Current through Register Vol. 54, No. 28, July 13, 2024
(a)
Routine.
A schedule for systematic maintenance shall be
					 developed and set down in writing for all installations subject to the
					 provisions of this Subchapter. Such schedule should be based on a maintenance
					 manual which shall be provided by the designer of the tramway. The manual shall
					 include the type of lubricant and frequency of lubrication of each element
					 involving moving parts. It shall stipulate that parts showing excessive wear
					 shall be replaced immediately and, if possible, establish yardsticks to define
					 excessive wear. It shall include a schedule for checking and tightening all
					 bolts especially on rope attachments. The maintenance schedule shall establish
					 a specific period of time which will represent one complete cycle of
					 maintenance operations, including all component parts, assigning a time within
					 such cycle for the maintenance work on each component. The schedule shall
					 include a daily check of all normal operating brakes, all communications, and
					 all stopping devices, both manual and automatic. A daily check shall also be
					 made to assure that the counterweight sheaves are free to turn. Also included
					 shall be periodic checks of all emergency brakes. A signed complete log or
					 diary shall be kept of the actual execution of maintenance work recorded daily.
					 Such log shall not only state that the component is given attention on that
					 day, but also the condition of the component if it shows any signs of
					 deterioration, and also the replacement of any components. It shall also
					 contain a daily record of the position of all counterweights and bull wheel
					 carriages.
(b)
Special
					 inspections.
Each tramway shall be inspected at least once each year
					 by a specialist acceptable to the authority having jurisdiction.
(c)
Special requirements for cables.
Ropes and cables in all installations subject to the provisions of
					 this Subchapter shall conform to the following:
(1)
Track cables.
All end
					 connections and areas near saddles shall be inspected at established intervals
					 of time for broken wires and worn spots. At longer intervals, the whole length
					 shall be inspected. Such intervals shall not be longer than those recommended
					 by the track cable manufacturer.
(2)
Hauling ropes.
The
					 general condition of hauling ropes, including those of cable links for monorail
					 lifts, and also including splices, shall be noted each day by the observation
					 of one complete cycle under normal operating conditions. At established
					 intervals, the whole length of rope shall be examined for conditions such as
					 broken wires, worn spots, pitting, lubrication, and the like. Fixed grips shall
					 be moved and the rope inspected at least once every 2 years, but not at longer
					 periods than recommended by the tramway designer. For purposes of maintaining
					 orderly and useful records, it is suggested that they be moved uniform
					 distances and always in the same direction. Each time a fixed grip is moved,
					 the rope which has been under and near the grip shall be examined for
					 deterioration, and records should be made which will make it possible at any
					 time during the life of the rope to locate the spots where grips have
					 previously been located. On the link-type hauling ropes of monorail lifts with
					 swaged button-end fittings, links should be removed at random and proof-tested
					 for safety factor and signs of corrosion annually or more often as
					 required.
(3)
Counterweight
					 and other ropes and cables.
Counterweight and other ropes and cables
					 are subject, when applicable, to the provisions specified for track cables and
					 hauling ropes in paragraphs (1) and (2).
(4)
All ropes and cables.
Lubrication shall be carried out in accordance with the recommendations of the
					 designer of the tramway. Retirement of rope from service shall occur on the
					 basis of the general condition and history of the rope and its predecessors as
					 indicated by the inspection reports. Consideration shall be given to the
					 condition of the splices, the deterioration or corrosion, the surface wear and
					 the number of broken wires in the worst rope lay.
