REPAIR
Repair of the crane boom assembly is accomplished by the replacement of worn or damaged parts. Disassembly and
assembly procedures are outlined in this work package.
Prior to initial use, all new, extensively repaired, or altered lifting devices shall be given a functional test to determine
operability of the equipment. Functional testing requirements are indicated in WP 0222 00 and in TB 43-0142. Before perform-
ing the functional test, the proper operation of brakes and limit, locking, and other safety devices shall be tested under no-
load conditions.
REMOVAL--SECOND BOOM AND SECOND BOOM CYLINDER
WARNING
Use a suitable lifting device to lift heavy loads. Heavy loads can crush. Do not allow
any body parts to come under the load or between the load and a stationary object.
Failure to comply can result in serious injury or death.
Cleaning solvent is flammable and its vapor is potentially explosive. Do not use clean-
ing solvent in the vicinity of spark, open flame, or excessive heat. Do not use cleaning
solvent in unventilated spaces. Failure to comply can result in serious injury or death.
