NBT40-1 SERIES OPERATOR MANUAL SET-UP
STOW PEGS FOR HOIST ROPE
This is the recommended stowage location for the hoist
ropes and must be used when reconfiguring for Aerial Lift
Platform use. Stow pegs located on top of the boom keep the
hoist ropes secure when not reeved over the boom nose.
The main hoist rope is stowed on the right peg and the
auxiliary hoist rope is stowed on the left peg as viewed from
the back of the boom.
The hoist rope must be secured to the boom stow pegs. See
the instructions for a boom mounted hoist “Hoist Rope Tie
Down” 6-9.
A2-B WEIGHT INSTALLATION AND
STOWAGE
To prevent the hoist rope from slipping out of the A2B weight,
rig the weight as shown in Figure 6-9.
Wire Rope
The A2B bracket is for single part line with wire rope use
only. Remove the A2B bracket shown in Figure 6-9 from the
hoist wire rope when changing from a single part line to a
multiple part line to allow the hoist wire rope and wedge
socket to reeve through the sheaves on the boom nose and
the hookblock. Re-install the clamp and nuts to the wire rope
before performing a lift.
Synthetic Rope
Ensure the synthetic rope is rigged through the slot in A2B
weight as shown in Figure 6-9. Do not use A2B bracket and
wedge assembly when equipped with synthetic rope.
For detailed information concerning synthetic hoist rope,
refer to K100™ Synthetic Crane Hoist Line Manual P/N
9828100734 available by contacting Manitowoc Crane Care.
