THE NEW CSA Z98-01 PASSENGER ROPEWAYS STANDARD GOES INTO EFFECT AS OF MARCH 1ST 2002 UNDER ALBERTA REGULATION 3/2002

Starting March 1, 2002,
· new or altered ropeways must be designed and installed in accord with CSA Z98-01; and
· any changes in Section 11 (Inspection, Testing, Operation and Maintenance) become effective for all lifts.

Effected parties should obtain and thoroughly review a copy of the new code for complete details. Copies can be purchased through the Canada West Ski Areas Association or Canadian Standards Association, Etobicoke, Ont. or Edmonton).

<<<< Noteworthy Changes in CSA Z98-01 >>>>

Section 8 Contains requirements pertaining to ropeways for Secondary Carriers (e.g. Tube Tows). Section 11 contains requirements formerly in Section 8
Section 9 Is reserved for future requirements for Belt Tows (conveyors). Section 10 contains requirements formerly in Section 9

Section 5 - Circulating Passenger Ropeways

5.6.1        When any stop function is initiated its brake system(s) is/are required to decelerate the rope between a minimum 0.45 m/s and maximum 1.5 m/s
5.6.2        The maximum and minimum permissible deceleration rates for emergency brake and service brake acting independently is between a minimum 0.45 m/s and maximum 1.5 m/s
5.6.4        The deceleration rate of haul rope shall be not greater than 2.0 m/s if loss of power or control malfunction would result in application of one or more braking systems
5.13.1      Maximum Downhill Loading Speed (former, Maximum Exit Slope from Stations)
“Where the haul rope slopes downward from a detachable station, the designer shall specify the maximum rope speed at which detachable carriers with passengers or a following empty carrier may depart from the station. To prevent open grips from sliding down the haul rope, the maximum stopping distance at this maximum loading speed measured from the last grip check switch shall be not more than 2/3 the length of horizontal rope at the station exit. The type of stop shall be consistent with the outcome of the grip fault.”

Section 6 Surface Passenger Ropeways

6.7.1.1        One or more service brakes must be provided where necessary and each brake must be applied when the ropeway is stopped

Section 11 - Inspection, Testing, Operation and Maintenance

Note (3) For secondary carriers’ one attendant may monitor two unloading stations if the duties on one ropeway do not preclude proper surveillance on the second ropeway
11.6.7      Persons responsible for ordering use of a bypass circuit must determine if the indicated fault exists, only authorized persons can order a by-pass and by pass must be maintained by continuous physical effort by the operator
11.6.12    Where the haul rope slopes downward from a detachable station, no person shall be loaded at a haul rope speed that exceeds the maximum speed specified in clause 5.13.1
11.12.1 (j) an inspection of attachments for secondary carriers (added to items to be included in daily inspections prior to transporting passengers)
11.12.4 (b) Evacuation and auxiliary drive tests and operation shall be performed with the main power disconnected
11.16.3.4 (c) Non-metallic evacuation ropes of synthetic polyester fibre or hard-lay nylon must be minimum diameter of 12.7 mm
11.22.2    Critical components that are replaced, modified or repaired shall conform to the fatigue requirements of clause 3.6
