3. Always connect dust caps to the ends of cables and
terminating plugs that are not in use.
Removing Extended Upper Boom Point
See Figure 6-5 for following procedure.
Failing to perform following steps will prevent load
drums from hoisting and boom from lowering. Also, a
fault alarm will come on.
1. Disconnect the electric cable from cable reel (26) at the
IN receptacle on wireless transceiver (6) on the boom
cap.
2. Connect a dust cap to end of the cable and coil the cable
onto the cable reel.
3. Connect terminating plug (24) either to cable (WNBE) at
BUS interface node controller (25) or to cable (WNE16T)
on the rotating bed.
4. Connect dust caps to the ends of cables and terminating
plugs not in use.
Maintenance
At least once weekly , inspect and test the block-up limit
switches, as follows:
1. Lower the boom onto blocking at ground level and
carefully inspect the following items:
a. Inspect each limit switch lever and actuating lever
(Figure 6-6) for freedom of movement. Apply one-
half shot of grease to the fitting on the actuating
lever. Wipe away any excess grease.
b. Inspect each weight (Figure 6-5) for freedom of
movement on the load line.
c. Inspect each weight, each chain, each shackle and
each connecting pin (Figure 6-5) for excessive or
abnormal wear. Make sure the cotter pins for the
shackles are installed and spread.
d. Inspect the entire length of electric cables for
damage.
e. Check that electric cables are clear of all moving
parts on the boom and extended upper boom point
and that the cables are securely fastened with clips
or nylon straps.
f. Check that all cables and terminating plugs are
securely fastened.
2. Test the block-up limit controls for proper operation
using either of following methods:
a. BOOM LOWERED: Manually lift each weight —
one at a time — while the engine is running. The
corresponding load drum should not operate in the
up direction and the boom hoist should not operate
in the down direction.
b. BOOM RAISED: Slowly hoist each load block and
weight ball — one at a time — against the weight.
When the chain goes slack, the corresponding load
drum should stop hoisting and the boom hoist
should not operate in the down direction.
CAUTION
Prevent Damage
To prevent two-blocking from occurring, do not operate
c r a n e u nt i l c au s e f o r i m pr op e r o p er at i o n a n d a l l
hazardous conditions have been found and corrected.
CAUTION
Avoid Sheave Damage
Use extreme care when testing block-up limit controls
when boom is raised. If block-up limit control fails to stop
load, immediately stop load by moving drum control
handle to off; otherwise, two-blocking may occur.
