Inspection
GENERAL CONDITION
Inspect the machine in general for wear, leakage, and damage.
AIR TANKS
Open the air tank drain cocks to blow out moisture and sediment.
FUEL FILTER
See carrier chassis supplier recommendations for service. See also, “Daily Check.” on page 138.
Anti-Two-Block SYSTEM
Inspect all ATB switches found on boom, jib, and auxiliary sheave heads for damage. Check the freedom
of counterweight attached to these switches; and also, that counterweight is attached around correct
line of hoisting cable in the proper manner. Inspect all electrical connections and wires as well as the
entire length of cable attached to the cable reel and it’s connections for evidence of excessive wear,
damage, or improper installation. Check spring loaded cable reel for proper tension and to insure that
reel is free to rotate. Verify visual and audible warning devices by lifting each of the counter weights.
This crane is equipped with a disconnect system on the control linkages. A check of this system should
be made prior to lifting. Hoist the hook block to the boom point so that actual contact between block
and ATB counterweight is made. If all functions are operating properly, winch hoisting will cease and the
boom cannot be extended or lowered. Should any of these functions continue, disconnect system is
functioning improperly and a complete system check must be made. Boom raise, boom retract, and
winch downfunctions remain active and will be unaffected by ATB system.
When performing disconnect test, care should be taken as damage may result if
disconnect system malfunctions and the hook block is drawn into the boom point.
PUMP DISCONNECT
See Power Take-Off topic in Description of Machine and Controls section of the manual.
