ANSI A Vehicle Mounted Elevating and Rotating Work Platforms
All unsafe ans shall be replaced or repaired before use. A z92.2 line clearance tree trimmer, as an operator, shall not approach energized conductors or facilities that will place the insulating or non-insulating aerial device, the operator and other occupants, and their tools, closer to such facilities than the distances set forth in Parts 29 CFR Proper operation of interlocks.
A person who has received training, understands and is conversant in the electrical hazards involved in the placing of an aerial device, platform occupants and their tools closer to energized lines and facilities than the distances listed, and has approval to perform the work. Training of qualified person s is the responsibility of the employer or his designated contractor s and can be classroom, hands-on or a combination, as deemed appropriate by the employer for the degree of risk involved.
The conference includes an Equipment Demonstration and Display, which in was the site of more than 60 exhibits. Please first log in with a verified email before subscribing to alerts. The lifting of an outrigger during operation shall not disable boom functions.
Categories B and C machines may incorporate control systems with high electrical resistance components. Annsi lower controls of insulating aerial devices shall be designed in such a manner that an operator is not placed in the electrical path between the aerial device and the ground. A lanyard connector shall not pinch between components having 9a2.2 movement with the anchorage s.
These aerial devices shall be equipped with a lower test electrode system. The revision of A Check hydraulic and pneumatic systems for observable deterioration and excessive leakage. Should the original manufacturer no longer exist, an equivalent entity may determine the required procedure.

Check visual and audible safety devices for proper operation. Controls return to neutral when released and not sticking. The operation of outrigger interlocking devices does not assure aerial device stability. Under the direction of a qualified person, the trainee shall operate the aerial device for a sufficient period of time to demonstrate proficiency in the actual operation of the aerial device.
Minimum approach distances must be maintained by the electrical worker to assure clearances between objects at different electrical potential when performing live-line work. The manuals shall contain:. Whatever upper control arrangement is provided shall be identified.
The winch line shall not be considered as insulating. This standard is also available to be included in Standards Subscriptions. Insulated Insulating Aerial Device — An aerial device with dielectric components designed and tested to meet the specific electrical insulating rating consistent with the manufacturer’s identification plate.
Deployment may be sensed when the outriggers meet resistance or by receipt of an indicative response that the outrigger deployment is beyond a predetermined position. Category C — Aerial devices which are not equipped with a lower test electrode system and are designed and manufactured for work in which the boom is not considered as primary insulation, but secondary, such as that using insulating rubber gloves.
The strength requirement shall apply only to the anchorage s and their a9.22 to the boom, platform or platform mounting. The override mode shall maintain its function while unattended.
Insufficient supporting surfaces such as soft ground or tamped q92.2 fills. The location of the manuals. The subcommittee worked on the standard from until its eventual approval in July
