2. Calculations indicate that at the point of
closest approach of the hoists, with rated capacity
load on the hoists, the monorail track beam and
monorail support points (and appurtenances) are not
loaded in excess of the load condition imposed by
any one hoist with rated load in any location.
Should conditions 1 and 2 exist, than the capacity
of the monorail system may be comparable to the
capacity of the highest rated individual hoist in
the monorail track system. Do not specify a
monorail system of greater capacity than required as
this will increase the system cost.
**************************************************************************
The hoist shall have a minimum rated capacity of [_____] metric ton tons.
The monorail system shall have a minimum rated capacity of [_____] metric
tons tons.

Hook [Lift and] Speed

NOTE: Unless otherwise specified, the nominal rated
maximum speed of the hoists will be the
manufacturer's standard within the limits of Table
1, for 2, 3, and 5 metric ton ton capacity hoists.
