In this article: Section 58 — Passenger Ropeways and Similar Equipment. Rule 58-000 states that Section 58 is a supplementary or amendatory section of the code and applies to passenger ropeways as defined in the CSA Z98, Passenger Ropeways and Passenger Conveyers standard, which includes tramways, chairlifts, gondolas, surface ropeways, passenger conveyors, and similar equipment. In addition, ANSI B77.1, Passenger Ropeways – Aerial Tramways, Aerial Lifts, Surface Lifts, Tows and Conveyers - Safety Requirements, and Can/CSA-C22.3 No.1, Overhead Systems should be referenced.



Appendix B and the CE Code Handbook provide additional information.

Rule 58-002 provides special terminology definitions for Cabin, Messenger, Passenger Conveyor and Station.

General requirements

Rule 58-010 requires that, in addition to the spacing requirements of Rule 2-308, the headroom in working spaces around controllers, disconnecting means, and other electric equipment must be no less than 2.0 m. Part 2 of the rule provides that the requirements for headroom may be relaxed provided that

Rule 58-012 specifies that circuits of less than 50 volts must be bonded to ground as per Rule 10-114.  Communication, control, remote control, monitoring, supervision, and signal circuits may be isolated, and grounded in accordance with Rule 10-206. The haul rope for these circuits may be isolated and ungrounded.

Rule 58-014 limits voltage for all circuits to 300 volts-to-ground except for

Rule 58-016 provides that luminaires for night skiing or similar floodlighting applications may be installed on passenger ropeway towers and stations if there is a circuit breaker, installed in a lockable enclosure that disconnects all ungrounded conductors, and that each circuit to the luminaires is protected by a ground fault circuit interrupter (Class A GFCI).


Rule 58-102 specifies that the minimum size of conductors for all communication, control, remote control, monitoring, supervision, and signal circuits shall be No. 26 AWG copper, except for circuits contained in travelling cables where the minimum size must be No. 20 AWG.

Rule 58-104 permits that

Note that optical fibre cables include conductive, non-conductive and hybrid types as defined in Rule 56-102.

Wiring methods

Rule 58-200 outlines acceptable wiring methods in passenger ropeways and similar equipment:

Rule 58-202 requires that supports for travelling cables be located and provided with suitable guards to prevent damage to the cables and contact with other equipment.

Protection and control

Rule 58-300 requires that motor control devices be arranged, as per rules 28-312 and 28-400, to prevent automatic restarting after shutdown where restarting could cause injury to persons.

Rule 58-302 provides that disconnecting means for the ungrounded conductors of the main drive motor and auxiliary drive motor, including their ventilation and control circuits, for each passenger ropeway or passenger conveyor must not contain a provision to automatically close the disconnecting means, and must be

Rule 58-304 provides that disconnecting means for utilization equipment must be

Rule 58-306 requires that overcurrent protection be coordinated with any upstream overcurrent protective devices.

Rule 58-308 requires that every 125 V, single-phase receptacle installed in machine rooms, control rooms, machine spaces, control spaces, and counterweight enclosures be protected with a Class A type ground fault circuit interrupter.

Rule 58-310 specifies that motor controllers be rated to comply with Rule 28-500(1) except where the controller limits the available power and is labelled “power limited”. 

Branch circuits

Rule 58-400 requires that each machine room, control room, machinery space, and control space must have

Rule 58-402 requires that where counterweights are installed in a building or room, luminaires, not supplied from the load side of the ground fault circuit interrupters required by Rule 58-308, must be provided and a separate branch circuit must supply lighting and receptacles.

Rule 58-404 specifies that utilization equipment other than that identified in rules 58-400 and 58-402, must be supplied by a separate branch circuit with overcurrent devices located in the machinery room, control room, machinery space or control space.

Regenerative power

Rule 58-500 requires that means must be provided to absorb regenerative power that cannot be absorbed under overhauling load or braking conditions.

In the next installment, we will be discussing Section 60 — Electrical Communications Systems.
