Each step shall be sub- jected to a lb kg mass load applied to its center while the machine is stationary.
Head-pulley lagging shall be changed in conjunction with belt replacement. This minimum 66 in. This periodic inspection shall cover, but is not limited to, the following items: The landing surface at the entrances and exits to the manlift shall be constructed zsme maintained to provide safe footing at all times.

The request for interpretation should be clear and unambiguous. The Standards Committee that approved the code or standard was balanced to assure that individuals aasme competent and concerned interests have had an opportunity to participate. A torn belt is also considered severe. When replacing old belts with new belts meeting tensile strength requirements for 12 in. Adequate lighting, not less than 5 fc 54 lxshall be provided at each floor landing at all times when the lift is in operation.
Handholds 20, Photo eye — sonic safety if applicable 4. A draft revision was completed in and approved by letter ballot in The lower edge of this hood shall extend at least 44 in.
Lower safety stops 2. No reproduction may be niade of this material without written consent of ASME. The A90 Standards Committee regularly holds meet- ings that are open to the public. These main drive supporting members shall be designed to support the entire combined loads of the pulley, belt steps [ lb 90 kg on each, step], hand- holds, all of the drive machinery plus the bottom pulley and related bottom pulley components that contribute awme the load on the head pulley.
Each handhold shall sup- port a load of lb kg mass without appreciable deformation or injury to its fastenings.
ASME A90.1 (2003): Safety Standard for Belt Manlifts
All elevator bolts used for join- ing the belt or securing handholds or steps to the belt shall be installed and maintained so that the heads do not project beyond the inner surface of the belt see Table 4.
Head shaft, couplings, collars, and keys Manlifts covered by this scope consist of steps plat- forms and accompanying handholds mounted on, or attached to, an endless belt operating vertically in one direction only aasme being supported by, and driven through, pulleys at the top and bottom. Such damage is not continuous across the full width a901.

A lap splice that has become cracked or damaged may be converted to a s90.1 splice and returned to service, provided that the damaged area to the splice is completely removed. A time delay switch may be required as part of an electronic device installation to permit passage of empty steps.
This was accomplished only with a great deal of individual member research and study, coupled with numerous meetings of the entire committee. No ladder passage through a floor or platform is required. Handholds attached to the belt shall be provided and so installed that they are not less than 4 ft 1.

When pulled in the opposite direction of travel, the a901 will be restored and the brake released, without having to reset motor controls. No encroachment of structural or machine supporting x90.1 within this space shall be per- mitted. When one V-belt is replaced, all belts shall be replaced. The manlift with lb 90 kg mass on each horizontal step of the down- run shall show no appreciable slip of the belt when standing or running at rated speed.
The breaking strength of the manlift belt shall be not aske than 30, lb N minimum tensile strength for belts with ft 30 m of travel or less; 44, lb N minimum tensile strength for belts with to ft 31 to 46 m of travel; and. Barnes, Alternate, Barnesco, inc.
