SET-UP 1400A OPERATOR’S MANUAL
STOW PEGS FOR HOIST CABLE
Stow pegs located on top of the boom keep the hoist cables
secure when not reeved over the boom nose. The main hoist
cable is stowed on the right peg and the auxiliary hoist cable
is stowed on the left peg as viewed from the back of the
boom.
MULTIPART LINE REEVING
Multipart line reeving enables greater loads to be lifted than
can be lifted with single part line. However, loads are limited
by the stability and structural integrity of the crane. The load
must be within the limits contained in the load chart.
Using Multiple Part Lines
The hoist data chart provides information for pull limitations
on the hoist with various multipart reevings. These ratings
are based on providing the proper operating safety factor on
the cable supplied with the machine. Therefore, any
replacement rope must meet the cable specification in of this
manual.
Lifting A 33 Ton (66,000 Lbs) Load
The 1400A is rated to lift 66,000 lbs (33 ton) at a 5 ft radius
with all booms retracted with an eight part block.
NOTE: Only use 5/8 inch wire rope with a rated breaking
strength of 45,400 lbs on this machine.
All pulls shown below are on the fourth layer. The line pulls
increase and the speed decreases on the third, second, and
first layers.
NOTE: Keep at least three wraps of loadline on the drum at
all times.
Do not deadhead hook block against boom tip
when extending the boom.

The hook block must be sized to the number of line parts. For example, do not use a six part line hook block on a three part line reeving. Contact
your National Crane Distributor or Manitowoc Crane Care to order the proper hook block.
