Compliance Standard - Above-Surface Passenger Ropeway

Compliance Standards for Above-Surface Passenger Ropeways

Aging Ski Lift Engineering Review and Assessments

• Aging Ski Lift Assessments are required for lifts once they reach 15 years of age. To determine if your device is due for an assessment, view the Aging Ski Lift Periodic Engineering Review and Assessment Schedule.

Evacuation Drive

• REPAIR / REPLACE – If the evacuation drive fuel tank does not have the correct capacity to unload the full length of the ropeway without re-fueling.
• SHUT-DOWN – If the evacuation drive is not operative (includes connections).

Drive and Return Sheaves - Bull Wheels

• REPAIR / REPLACE – If there is no means to retain drive and return sheaves in their approximate operating positions in the event of bearing, shaft, or hub failure.
• REPAIR / REPLACE – If sheaves are found to have structural defects.

Tensioning Systems

• SHUT-DOWN – If carriage limit switch is not operative.
• REPAIR / REPLACE – If carriage limit switch is not adjusted properly (to stop within 150 millimetres of the physical limits of the carriage).

Hydraulic Tensioning

• SHUT-DOWN – If the relief valve is not operational once the pressure is 10% above that at which the valve opens or the rating noted in the acceptance test procedure/maintenance manual.
• SHUT-DOWN – If high or low pressure limiting devices are not operative.
• SHUT-DOWN  – If the velocity fuse is not operative.

Counterweight

• SHUT-DOWN – If the counterweight is not in full suspension at all times during operation.
• SHUT-DOWN – If the counterweight travel switch is not operative.
• SHUT-DOWN – If the counterweight tensioning ropes are not adjusted to provide at least 150 millimetres of remaining carriage travel when the counterweight reaches its upper or lower limits.
• SHUT-DOWN – If the counterweight wire rope is damaged.
• REPAIR / REPLACE – If the annual visual non-destructive testing (NDT) of the whole length of the counterweight rope and its connections was not completed.
• REPAIR / REPLACE – The three year or exceeding 4,000 hours non-destructive testing (NDT) (MRT) of the counterweight rope has not been completed.

For devices that fall under Bulletin LPC 2003-004

• REPAIR / REPLACE – If annual non-destructive testing (NDT) was not completed as per the bulletin.

Communication Systems

• SHUT-DOWN – If communication systems are not operative at the unloading and loading area.

Tower Clearance

• REPAIR / REPLACE – If hanging tree limbs are encroaching or contacting the carriers.
• REPAIR / REPLACE –  If any ski tip deflectors are missing.

Towers and Equipment

• SHUT-DOWN – If the tower or station de-ropement switch is not operative.
• SHUT-DOWN – If the tower de-ropement switches are not of sufficient length in order to stop the ropeway if the rope leaves its normal running position.
• SHUT-DOWN – If the rope position switch is not adjusted to ensure the ropeway will stop when the rope is out of position.
• SHUT-DOWN – If the tower has structural defects.

Sheaves

• SHUT-DOWN – If any electrical protective device on the tower sheave assembly is not operative.
• REPAIR / REPLACE – If the tower sheave assembly is damaged, worn or bent.
• REPAIR / REPLACE – If the tower sheave assembly is not aligned correctly.

Grips

• REPAIR / REPLACE – If the non-destructive testing (NDT) of a minimum 20% or ten grips, whichever is greater, is not completed (including grips or inserts, hangers, and critical carrier location).
• SHUT-DOWN – If the slip test of the grip is not within specification.
• SHUT-DOWN – If grips have structural damage.

Chairs

• REPAIR / REPLACE – If the correct number of carriers are not installed on the line as per the design submission.
• REPAIR / REPLACE –  If clearance of four metres is not being maintained from the bottom of the carrier to the snow profile, ground or any obstructions where persons are permitted.
• SHUT-DOWN – If chairs have structural defects including welds, seats, safety bars or missing/damaged fasteners.

Detachable Chairs

• SHUT-DOWN – If the anti-collision system is not operative.
• SHUT-DOWN – If the ropeway does not stop when:

• SHUT-DOWN – If the safety gate is not at least 1.5 times the maximum stopping distance from the bull wheel.
• SHUT-DOWN – If the safety gate is not operative.

Operation

• REPAIR / REPLACE –  If the line equipment or carriers are not cleared of ice and snow.
