7. Verify display of main boom length agrees with actual
boom length.
8. Verify display of main boom angle agrees with actual
boom angles.
9. Verify display of the crane operating radius agrees with
the actual radius.
10. Verify load display by lifting a load of known weight.
Load display accuracy must be within the tolerance
range.
HOIST ROPE REEVING
NOTE: 35 x 7 (rotation resistant) wire rope is used on this
crane.
Within load and range chart limits and permissible line pull,
multi-part lines allow the operator to raise a greater load than
can be raised with a single part line. Various hoist rope
reeving (part line) is possible with the boom nose and hook
block (Figure 5-10 and Figure 5-15). Reeving should be
done by a qualified rigger using standard rigging procedures.
To quick reeve the hook block without removing the wedge
socket on end of hoist rope, remove the retaining clips from
the two pins (1, Figure 5-10), then drop the two rope guards
(2) to their lowered position.
Reeving Hoist Rope Over the Boom
For cranes equipped with a rope guide, obey the following
instruction.
Always reeve main hoist rope through rope guide
(1, Figure 5-11). Always reeve auxiliary hoist rope outside
rope guide.
DEAD-END RIGGING/WEDGE SOCKETS
Wedge socket assemblies are popular rigging accessories
used for decades to terminate wire ropes on mobile cranes.
A wedge socket assembly is easily installed and dismantled,
but must be installed and used correctly. Use only a wedge
and socket of the correct size for the rope fitted. Failure to do
so may result in rope pulling through fitting.
Since state and local laws may vary, alternate attachment
methods may be necessary depending upon work
conditions. If alternate methods are selected, the user is
responsible and should proceed in compliance with the
regulations in force. If there are any questions, contact your
local Grove distributor or Manitowoc Crane Care.
Do not mix components from different manufacturers. The
selection, installation, and use of a wedge socket assembly
must be in accordance with requirements of the wedge
socket manufacturer and wire rope manufacturer upon
whose wire rope the wedge socket assembly will be used.
Grove specifies size, type, class, and line pulls for wire rope;
predominately rotation resistant wire rope, and rigging
accessories such as overhaul balls and hook blocks for use
with each new crane it manufactures.
Other wire ropes and rigging accessories are available from
various vendors. Different wire rope manufacturers have
differing requirements for construction, handling, cutting,
seizing, installation, termination, inspection, and
