the RCL, and the wind speed indicator.
Removing Upper Boom Point or Jib Point
for the following procedures.
Failing to perform the following steps will prevent load drums
from hoisting and boom (or luffing jib) from lowering. Also
operating limits alert will come on.
Remove terminating plugs and reconnect electric cables to
proper receptacles when corresponding attachment is
reinstalled.
If upper boom point, upper luffing jib point, or fixed jib is
removed:
1.
Disconnect cable from receptacle (14, View C).
2.
Unscrew sealing cap (6, View C) from terminating plug
(7) and attach to receptacle (14).
3.
Connect sealing cap to end of cable and store on upper
boom point or upper jib point.
If the luffing jib is removed:
1.
Unscrew sealing cap (1, View C) from terminating plug
(2).
2.
Disconnect cable from receptacle (15, View C).
3.
Connect terminating plug (2, View C) to receptacle (15).

Connect sealing cap to end of cable and coil cable onto
cable reel (luffing jib butt).
5.
Remove sealing caps (7, View C) from terminating plugs
(6) and connect terminating plugs to jib stop receptacles
(16, 17, and 18).
Storing Electric Cable
for the following procedure.
The electric cables for the boom and jib are long enough to
accommodate the maximum length of each attachment.
Store excess electric cable for the boom and luffing jib by
winding it onto the reel mounted on the respective butt. The
reel has a locking pin. Disengage the locking pin to allow the
reel to be wound. Engage the locking pin to lock the reel in
position. The electric cable from the crane to the reel must be
disconnected before the reel can be wound.
Store excess electric cable for the fixed jib by winding it
around the brackets on the fixed jib.
Maintenance
Inspect and test the block-up limits
weekly or every 40
hours of operation
, as follows:
1.
Lower the boom and jib onto blocking at ground level
and carefully inspect the following items:
a.
Inspect each limit switch lever and actuating lever
for freedom of movement. Apply one-half shot of
grease to fitting on the actuating lever; wipe away
any excess grease.
b.
Inspect each weight for freedom of movement on
the load line.
c.
Inspect each weight, chain, shackle and connecting
pin for excessive or abnormal wear. Make sure
cotter pins for shackles are installed and spread.
d.
Inspect entire length of each electric cable for
damage.
e.
Check that electric cables are clear of all moving
parts on boom and jib and that cables are securely
fastened to boom and jib with nylon straps.
f.
Check that all plugs are securely fastened.
2.
Test block-up limits for proper operation using either of
the following methods:
a.
BOOM LOWERED: Manually lift each weight —
one at a time
— while engine is running. Load drum
should not operate in HOIST direction and boom
hoist should not operate in LOWER direction.
b.
BOOM RAISED:
Slowly
hoist each load block and
weight ball —
one at a time
— against weight.
When chain goes slack, corresponding load drum
should stop HOISTING and boom hoist should not
operate in LOWER direction.
CAUTION
Avoid Machinery Damage!
To prevent two-blocking from occurring, do not operate
crane until cause for improper operation and all
hazardous conditions have been found and corrected.
