Entrances at all landings shall be in the same relative position. Handholds attached to the belt shall be provided and so installed that they are not less than 4 ft 1. The individual making the inspec- tion shall also make a special point to observe which persons are using the manlift and whether they are com- plying with the operating rules listed in para.

Such a ladder may be built into the supporting structure of the manlift and may be parallel to the plane of the manlift or perpendicu- lar to the plane of the manlift see Figs.
Such signs shall be of letters not less than 1 in. Head shaft bearings and lubrication 12, Floor hoods and openings The manlift with lb 90 kg mass on each horizontal step of the down- run shall show no ssme slip of the belt when standing or running at rated speed.
The bottom pulley shall be installed so that it is supported by the lowest floor served; or, where it is necessary to gain required clearance see para, 4.
ASME A90.1 (2003): Safety Standard for Belt Manlifts
Each step shall be sub- jected asem a lb kg mass load applied to its center while the machine is stationary. All such platforms shall then be considered part of the emergency landing and provided with standard railings and toeboards.
One of these devices shall activate while the step is still in the horizontal position. The depth of this floating hood need not exceed 12 in.
As such, users of this Standard may inter- act with the Committee a90.11 requesting interpretations, proposing revisions, and attending Committee meetings. The purpose of this rule is to provide a means of exit from a manlift step to the floor or platform below T it should a mechanical or power failure strand passengers between floors.

This was accomplished only with a great deal of individual member research and study, coupled with numerous meetings of the entire committee. Any stresses set up during acceleration or stopping are to be included in the above factor of safety.
Steps or handholds are pro- hibited on the belt splice. A lap splice that has become cracked or damaged may be converted to a butt splice and returned to service, provided that the damaged area to the splice is completely removed.
Belt 40 46 16 in. Top pulley and lagging The minimum and maximum distance from face of belt to edge of floor openings as shown in Fig, 1 is applicable to 12 in. The request for interpretation should be clear and unambiguous.
Bottom bearing lubrication and support Belt tracking at bottom pulley Arrows pointing in the direction of belt travel shall be marked on the belt below or above each handhold. Appropriate design safety factors shall be axme when designing the main drive supporting members.
One point of each phase may be the motor starter contacts and the other point should be an auxiliary contact with load carrying capacity equal to or greater than the motor starter contacts. Entry shown on two sides; entry on one side is adequate.
Cole, Alternate, Industrial Erectors, Inc. The overlap of the belt at the splice shall be not less than 3 asmw 0.
