3. Auxiliary hoist may be specified for handling
light loads (typically 10 to 30 percent of main
hoist rated load) at 2 to 4 times the main hoist
speed. Micro-drive should be specified if precise
handling and position are required. Micro-drive is
a single speed drive normally driving the crane at 5
mm/s (1 fpm) or less. Delete reference to
micro-drive and auxiliary hoist if not applicable.
**************************************************************************
Rated capacity of crane shall be [_____] metric tons tons. Auxiliary hoist
capacity shall be [_____] metric tons tons. Lower load block or assembly
of hook, swivel bearing sheaves, pins and frame suspended by the hoisting
ropes shall not be considered part of the rated capacity. Rated speeds (in
meters/second fpm) for the hoist, hoist micro-drive, bridge micro-drive,
trolley micro-drive, [bridge] [gantry] and trolley at the rated load shall
be as follows:
