SPECIFICATIONS
Crawlers:
Crawler assemblies can be hydraulically extended or retracted
for wide track operation or retracted for transportation.
Crawler belt tension adjusted with hydraulic jack and
maintained by shims between the idler block and frame.
Crawler drive:
The independent two speed hydraulic propel drive is built
into each crawler side frame. Each drive consists of a
hydraulic motor driving a propel sprocket through a
planetary gear box. The hydraulic motor and gear box
are built into the crawler side frame within the shoe width.
Crawler brakes:
Spring set, hydraulically released, multiple disk-type parking
brakes are built into each propel drive.
Steering mechanism:
A hydraulic propel system provides both skid steering and
counter rotating steering.
Crawler shoe:
66 shoes - 36” wide, each crawler.
Track rollers:
The track rollers are sealed for maintenance free operation.
Lower Machinery

Front drum:
Front and rear drums for load hoist powered by hydraulic
variable plunger motors, driven through planetary reducers.
Negative brake
A spring-set, hydraulically released multiple
disk brake is mounted on the hoist motor and
operated through a counter-balance valve.
