Section III. CRANE BRAKE AND CLUTCH BAND ASSEMBLIES
137. General
The operating clutches are of the internal
expanding type and controlled hydraulically. The band
assemblies are composed mainly of a clutch shoe with
lining, a clutch actuating arm and actuating arm
retracting spring, and a band retracting spring. The
brakes are of the external-contracting type mounted on
the outside of the clutch drums. They consist chiefly of
a two-part hinged-attached brake assembly with lining.
One end of the band assembly is anchored and the
other is actuated. The boom hoist brake is held in the
engaged position by a spring and released hydraulically
when the boom hoist clutch is actuated. The main hoist
and haul-back brakes are controlled mechanically and
are engaged by pressure on the brake pedals.
