Within the limits of the load and range charts and permissible line pull, multi-part lines allow the
operator to raise a greater load then can be raised with a single part line. This reeving should be
accomplished by a qualified rigger using standard rigging procedures.
Figure 6-4 illustrates cable reeving for the AT422T which includes routing the cable over the upper
boom nose sheave (1), lower boom nose sheave (2), hook block sheave (3), and lower boom nose
sheave (4) with the cable terminating at the wedge socket (5). Figure 6-5 shows 3-sheave boom
INSTALLING WEDGE AND SOCKET.
Use only a wedge and socket of the correct size for
the wire rope (cable) fitted. Failure to do so may
result in the rope pulling through the fitting.
Make sure the live-loaded side of the cable is in line
the wire rope is loaded incorrectly, it will bend under a
load as it leaves the socket. The edge of the socket
will eventually wear into the rope causing damage
Inspect the wedge and socket. Remove rough edges and burrs.
