If changes are made to the drive train components that effect rotational inertia i.
When requested, additional data pertaining to the design, construction, materials or equipment of a passenger ropeway shall be submitted to the department for approval or to substantiate compliance with this chapter. Any modifications made to h77.1 electrical design shall be clearly marked on the on-site documentation and signed by a Qualified Engineer.
IIIis hereby incorporated by reference into this chapter. Entire code is always current. When single sheaves are b777.1 for other than guide sheaves, which normally carry no load other g77.1 the weight of the rope and towing devices, the sheave diameter [should] shall not be less than 20 times the nominal rope absi. Lifts installed prior to the effective date of this standard may comply with Annex D of this standard or with the signage requirement of the edition of Code Rule Before a surface lift that is new or relocated or that has not been operated for routine maintenance within the previous 2 years is opened to the public, it shall be given thorough tests by qualified personnel to verify compliance with the plans and specifications of the designer.

Ropeway Information | NSAA
The designer or manufacturer shall propose and submit an acceptance test procedure. Prior b771 operation of newly installed aerial lifts or after any modification thereafter of the electrical system, the electrical system shall be tested and shown to meet [the snsi of] this [standard] Part and the test results shall be ahsi. As each grip is relocated, the haul rope shall be examined for deterioration at or near the grip location.
The initial installation and each relocation of a clamptype grip shall be field-checked by a method established by the designer to provide assurance that the requirement of the first sentence of 4. After each initial or periodic inspection, a permit to operate shall be issued by the department upon determination that the passenger ropeway meets the applicable requirements of this chapter.
Compliance with this chapter does not relieve the owner from compliance with other administrative rules or statutes. The owner of each aerial tramway shall submit to the Commissioner a anzi written plan for evacuation of passengers from cabins or carriers in the event of a power failure or breakdown.
All aerial lifts shall be equipped with at least two power units, one of which, at a minimum, meets the requirements of 3. For chair lifts, the unloading point where the passengers stand up and disembark shall be marked on or near the unloading surface. This line of authority shall list:.
Add to Alert PDF. If the resistance of the soil is not practically determinable, the foundation or anchorage [should] shall be designed as a gravity anchor, using a coefficient of friction appropriate to the general character of the soil.
If the document is revised or anai, you will be notified by email. The design coefficient of friction for a particular sheave liner shall not exceed the values shown in table The exit pathway [should] shall be inclined downward in the direction of travel and outward from the line of the uphill tow path to provide passenger movement away from the tow.
The design shall have a minimum factor of safety of 2 in resisting overturning and, concurrently, 2 against sliding, under dead-load and live-load conditions.
The use of temporary circuits that have been installed for the purpose of bypassing failed electrical circuit s see 5. Before an aerial lift that is new or relocated or that has not been operated for routine maintenance within the previous 2 years is opened to the public, it shall be given thorough tests by qualified personnel to verify compliance with the plans and specifications of the designer.
Structures and foundations located in snow creep areas shall be designed for such conditions and loads, or protective. The use of temporary circuits that have been installed for the purpose of bypassing failed electrical circuit s see 3. The drive sheave brake shall be capable of being activated both manually and automatically to stop and hold the aerial lift under the most unfavorable design loading condition.
Testing shall not be done while the tramway is open for public operation.
NOTE — Voice communication systems are not required for those tows qualifying for operation by a single operator, as defined in 6. The connection between the towing device and a b771 device shall be designed to minimize inadvertent detachment due to line surges including stops and starts and [should] shall not be detached by passenger movements without their reaching the towing device.
The width of the unloading path on the unloading platform and the breakover point shall be greater than the carrier width. Foot passengers shall be provided with approximately level unload platforms and the necessary handrails, steps, or ramps to exit the unload area.
