operate on [_____] volts AC, 60 Hz, [single] [three] phase power source.
2.1.1
Capacity
The monorail system shall have a minimum rated capacity of [_____] metric
tons tons ([_____] kg pounds.) Mark the hoist capacity in kg pounds on
both sides of the hoist or load block.
2.1.2
Speeds
**************************************************************************
NOTE: Slow full-load operating speeds invariably
provide improved load control and increased
productivity. The full-load speeds enclosed in
brackets are recommended for most applications.
However, should other speeds be required, the
following guidelines are provided:
1.
Hoist:
See Tables 1 and 2 below.
2. Trolley: 250 mm/s 50 fpm is recommended for one
speed motorized trolleys. For longer travel
distances a two speed trolley with a high speed of
500 mm/s 100 fpm is normally sufficient. In any
case, travel speed should not exceed the maximum
speed that the floor walking, pendant control
operator can comfortably negotiate in a work area,
approximately 750 mm/s 150 fpm.
