LOAD BLOCK TIEBACK
General
Two lugs are provided on the front of the rotating bed (View
A, Figure 4-58
) for tying back the load block when not in use.
Specifications
Shackle
See Figure 4-58 for tieback hole diameter. Size the shackle
accordingly.
Sling Length
The sling should be long enough to connect it to shackles in
the tieback holes and to the hook of the freely suspended
load block. This will prevent personnel from having to swing
the block in, toward crane, to make the connection.
Sling Capacity
The slings must be capable of supporting the weight of the
load block and 1/2 the weight of the wire rope suspended
from the boom point. When sizing slings, take into account
the dynamic affects of traveling and swinging the crane. It is
the crane user’s responsibility to calculate this load.
BOOM HOIST REEVING
The boom hoist wire rope must be reeved between the
gantry and mast sheaves as shown in Figure 4-59
.
Manitowoc provides a 7/8 in (22 mm) terminator socket and
wedge for anchoring the wire rope to the dead-end link in the
gantry.
The wire rope tail length must be at least 6 in (152 mm).
Wire Rope Installation
See Wire Rope Installation and Maintenance on Page 98 for
instructions on how to:
• Anchor wire rope to drum
• Install wire rope on drum
• Anchor wire rope to socket and wedge
CAUTION
Avoid damage to boom:
• Haul in load line only until tieback sling(s) is taut.
Purpose of tieback is only to prevent load block from
swinging when not in use.
• Do not tighten load line to point that load line rubs
against lacings in boom sections or load block can
bounce into lacings.
Operator, be aware that as you boom down load lines and
tieback sling will tighten even more. Pay out load line
while booming down so that you don’t pull load block into
boom. Damage to lacings or chords could result.
To ease installation, lower
mast to transport position.
