5. BRAKES:

5.1 Chair lifts in addition to service and emergency brakes shall be fitted with an automatic overspeed control which shall interrupt the power to the prime mover and actuate the service brake or similar independent brake.

5.2 A backstop brake to prevent an unintended reverse rotation shall be fitted to all lifts and tows.

5.3 The service brake, emergency brake, and backstop brake shall be independent systems such that the failure of one system will not impair the function of the other systems.

5.4 Unless otherwise specified herein, braking systems actuated by emergency stop devices shall be capable of stopping the rope within a distance of 3 ft under no-load conditions.

6. ELECTRICAL

6.1 1. All high voltage electrical installations shall comply with the standard set by the local territorial power supply authority whether that authority supplies the power or not.

6.2 2. All high and low voltage cable shall be buried underground in a line approved by the Board and for which a site plan has been deposited with the Board.

6.3 3. All electrical stop control circuits including emergency or safety stop systems shall be energised circuits, so that, in the event of malfunction of a switch or of electrical power failure, the lift or tow shall be inoperative.

6.4 4. Terminal machinery, towers, and wire rope shall be effectively grounded.

7. COMMUNICATIONS:

7.1 A chair lift shall be provided with an effective means of communication between both terminals and with any intermediate station.

7.2 Communication and control cables may be supported by the towers supporting the lift or tow but low voltage circuits only shall be installed.

8. LOADING AND UNLOADING AREAS:

8.1 Chair Lifts:

8.1.1 A loading ramp shall be level, in the same plane as the wire rope, and so constructed that a passenger can stand comfortably on skis without sliding forwards or backwards.

8.1.2 If any side of a loading or unloading ramp or platform has a steep drop, a guardrail shall be provided for the protection of passengers, lift attendants, and bystanders.

8.1.3 If the chair exit end of a loading ramp or platform has a steep drop-off exceeding 6 ft from the chair seat a safety net shall be erected and maintained in a safe condition, extending a distance of at least 15 ft from the end of the loading area, and those portions of the supporting structure likely to be struck by a falling passenger shall be effectively protected to prevent injury to the passenger.

8.1.4 The entry to an unloading ramp shall be so constructed that skis worn by passengers cannot be caught under the edge of the ramp or platform and will be guided upwards towards the unloading point.

8.1.5 An unloading place shall be level to enable foot passengers to disembark and shall be followed where possible by an inclined ramp, sloping sufficiently downwards from the exit of the unloading area to enable passengers to ski away from the chair clear of any machinery.

8.1.6 A tower adjacent to a loading point shall be guarded in such a manner to prevent skis worn by passengers becoming caught in the tower when they are becoming settled in the chair.

8.1.7 Where passengers on double chair lifts are required to embark from and disembark to the same side of the chair, the loading and unloading areas shall be the subject of special design and shall be approved by the Board before use.

8.2 Surface Lifts:

8.2.1 Unless the terrain at the loading point is naturally suitable, the licensee shall construct and maintain easy access to the lift.

8.2.2 The loading area shall be as nearly flat as is possible and of sufficient length to permit the passenger to embark safely.

8.2.3 Unless the terrain is naturally suitable, the licensee shall construct and maintain a flat or downward disengaging area for the passenger to disembark safely from the towing device.

8.2.4 The distance between the end of the unloading area and the upper terminal machinery shall be sufficient to allow the towing devices to become fully retracted and to permit their oscillations to diminish adequately before they enter the terminal.

8.3 Rope Tows:

8.3.1 The loading area shall be level, free of obstructions, and fenced in a manner to guide passengers to the loading point.

8.3.2 The unloading area shall be either flat or graded downwards and outwards from the line of the uphill track to provide movement away from the tow.

8.3.3 In the case of a rope tow using intermediate guide sheaves requiring the use of a rope gripping device, the loading area shall extend at least 30 ft before the first pylon is reached.

9. LIFT AND TOW LINES: (Surface Lifts and Rope Tows)

9.1 With the prior approval of the Board, a track width along the lift or tow line shall be cleared and maintained in such a manner that no rocks or other obstructions project above the snow surface for the full usable length of the lift or tow to a distance of 3 ft on either side of the centre line of the uphill track.

9.2 The designated track width shall be maintained free of snow ridges, wind scour, and humps and hollows likely to unbalance a passenger of ability consistent with the lift or tow in use.

9.3 With the prior approval of the Board, the licensee shall fill with rock all downhill sections along the usable length of the lift or tow over the designated width.

10. CLEARANCES:

10.1 Chair Lifts:

10.1.1 Where skiing is permitted beneath the lift line there shall be maintained a minimum vertical distance of 10 ft between the snow surface and the lowest point of a chair under conditions of maximum rope sag.

10.1.2 Where, because of abnormal snow build-up beneath the lift line, the minimum vertical distance of 10 ft cannot be maintained at any point, the licensee shall erect an effective barricade to prevent persons skiing or walking beneath the lift at that point or points.

10.1.3 The licensee shall not operate the chair lift in the event of abnormal snow build-up permitting chairs to strike the snow at any point.

10.1.4 Chair-lift terminals and towers shall not be constructed containing provision for change of the design height of the wire rope.

10.2 Surface Lifts:

10.2.1 Terminals and towers shall be located so that under the most adverse conditions, the towing device will not lift a passenger from the snow surface.

10.2.2 The haul rope shall, at all times, be high enough to clear a passenger's head by at least 2 ft.

10.2.3 The return rope shall be of sufficient height to keep down-coming towing devices clear of the snow.

10.2.4 The towers shall be of such a height and so located, that, if the up-going haul rope comes off the supporting sheave or sheaves of one tower, the towers (or terminal) on either side will support the rope clear of the snow by a minimum of 2 ft.

10.2.5 Where towers have provision to vary the height of the sheaves above the snow, changes in height of the sheaves shall be controlled in a manner to prevent overloading or underloading the tower sheave assemblies and any such changes shall be made only in accordance with the designers or manufacturers specifications.

10.3 Rope Tows:

10.3.1 The return rope and its supporting sheaves shall be kept at all times not less than 7 ft above the snow surface.

10.3.2 Where for technical reasons the return rope runs in the same plane parallel to or intersects the up-going haul rope and the return rope is less than 4 ft horizontally from the haul rope, this portion shall be barricaded off and shall not form part of the usable length of the tow.

10.3.3 There shall be a minimum distance of 3 ft between the haul rope and any pylon located between the loading and unloading areas.

10.3.4 Spikes, hooks, or other projections shall not be placed on rope supports lower than 7 ft above the snow surface.
