SHOE SLIP CONTROL SHOE SLIP CONTROL
REMARK
After the joystick (steering, directional, and gear shift lever) is
set to F1, the shoe slip control starts when the ripper lever is
operated to LOWER (c) or TILT. Even when the operation
alternates between dozing and ripping, there is no need to turn
the switch ON or OFF.
With this system, if shoe slippage occurs during ripping
operations, the engine speed is lowered to prevent wasteful
shoe slippage.
If shoe slippage occurs during ripping operations and the
engine speed goes down, if the ripper lever is operated to TILT
IN (A) or RAISE (a), the engine speed will rise (output is
increased) to make it easier to carry out breaking operations.
When carrying out ripping operations on hard rock, if the rear of
the machine comes off the ground and there is sudden shoe
slippage, it is possible to reduce the shoe slippage by operating
the ripper to LOWER (c) and reducing the engine speed.
