UNIVERSAL ANCHOR JOINT
See Figure 4-76 for the following procedure.
The dead-end socket and wedge can be anchored to any of
the following locations in the boom and jib point, depending
on the type of operation.
• Link in the boom or the jib point for the liftcrane operation
• Lug (if equipped) welded inside the boom or jib point
directly behind the boom or jib point shaft for liftcrane
operation
• Universal anchor joint located behind the boom or jib
point—This location provides greater separation
between the load lines, which reduces twisting of the
load. The universal anchor joint is used for the magnet,
clamshell, grapple, and liftcrane operation requiring a 2-
part load line.
NOTE: Movement of the dead-end socket on the link or lug
operation is in two directions only—forward and
back. Movement of the dead-end socket on the
universal anchor joint operation is in four
directions—forward, back, and sideways.
If the link or lug in the boom or jib point has been used for any
duty-cycle work with a 2-part load line, check for cracks due
to side-bending loads. Consult with the Manitowoc Crane
Care Lattice Team for the repair procedure.
If the boom or jib point is not prepared for the universal
anchor joint, the boom or jib top is neither designed nor
intended for duty-cycle work.
For the liftcrane operation requiring 3-part load line or
greater, it is necessary to remove the universal anchor joint.
This step will prevent interference of the universal anchor
joint with the wire rope at high boom angles.
For the wire rope size and the maximum load of the universal
anchor joint, see the appropriate wire rope chart, capacity
chart, or rigging drawing.
WARNING
Falling Load Hazard!
Prevent possible injury. Sideways motion of the load line
may break the link or lug, causing the load to fall.
Do not dead end a 2-part load line to the anchor link or lug
in the boom or jib point for a magnet, clamshell, grapple,
or other operation requiring rapid swing cycles.
WARNING
Falling Load Hazard!
Prevent possible injury. Interference of the wire rope with
the universal anchor joint can damage the wire rope,
causing the wire rope to break and the load to fall.
Do not operate the liftcrane at a high boom angle with the
universal anchor joint in place.
