MI.IATD-1472E
the design weight of items requiring two person lifting, provided the load is uniformly distributed
between the two lifters. If the weight of the load is not uniformly distributed, the weight limit applies
to the heavier lift point. Where three or mom persons are lifting simukanemdy, not more than 75
perecnt of the one-person value maybe added for caeh additional lifter, provided that the objeet lifted is
sufficiently large that the lifters do not interfere with one another while lifting. Where it is not possible
to define the height to which an object wiIl be lifted in operational use, the limit wkei.n the object is
lifted to shoulder height
shall be usedrather than the more permissivebenehheightvaiue. The va!ues
in Table XXIII are a~plicable to objeets with or without h~dlea.

5.9.11 .3.2 LiftillRfreuueneY. The equipment weight limits in Table XXIII are not for repetitive
lifting as found, for example, in loading or unloading transport vehicles. If the frequency of lift
exceeds one lift in 5 minutes or 20 lifts per 8 hours, the permissible weight limits shall be mdueed by
(8.33 x LF) percent, where LF is the lift frequency in lifts per minute. For example, if the lift
fmqueney is 6 lifts per minute, them*
~ permisaibie weight is mdud by 50 percent (8.33 x
6 = 50).
5.9.11 .3.3 Load size. The maximum permissible weight Iiil bits in Table XXIII app!y to an
object with uniform mass distribution and a compact size not exceeding 46 cm (18 in) high, 46 cm (18
in) wide, and 30 cm (12 in) deep (away from the iifter). This places the handholds at half the depth,
or 15cm (6 in) away from the body. If the depth of the objectexeceds61 cm (W in) the permissible
weight shall be reduced by 33 percent Xfthe depth of the object exceeds 91 em (36 in), the
permissibleweightshaii be rwhxd by W perc@nLIf thedepthof the object exceeds 122 cm (48 in),
the permissible weight shall be redueed by 66 percent.
