Steering mechanism :
The hydraulic propel system provides both skid steering and
counter-rotating steering.
Crawler shoe :
Casted 52″ shoe is in standard.
(48″ shoe is optional)
Track rollers :
The track rollers are sealed for maintenance free operation.
Lower Machinery
Carbody frame :
High-tensile steel welded axle in constructed frame.
Translifters :
The function allows quick and easy crawler frame removal
and trailer loading. The swing arm and the remote-
controlled 4 vertical cylinders are all standard features.
Crawlers :
Crawler assemblies are designed with quick disconnects for
individual removal as a unit from axles.
Crawler belt tension adjusted by hydraulic jack and
maintained by shims between the drive unit block and frame.
Crawler drive :
Each crawler has double motors, one in front and one in the rear,
delivering steady, powerful traction for smooth on-site travel.
Each drive consists of a hydraulic motor driving a propel
tumbler through a planetary gear box. The hydraulic motor
and gear box are built into the crawler side frame.
Crawler brake :
Multiple disc type, spring set, hydraulically released parking
brakes are built into each propel drive.
