11.25 AUXILIARY DRIVE BRAKE
The machine is equipped with an auxiliary drive brake,
which brakes the wheels in situations, when the pressure
in the hydraulic circuit drops (engine shut down, air in the
hydraulic circuit, result of using the “Emergency stop”
buttons). The auxiliary drive brake works on the principle
of a band brake, where the braking band brakes the
pulley of the hydraulic motor and consequently also the
wheels. The brake is controlled by a brake cylinder, which
is connected to the filling circuit of the hydraulic pump.
The braking effect will take place when the pressure in
the hydraulic system drops. When the pressure in
hydraulic system increases, the brake will be disengaged.
The brake includes a system, which allows the brake to
be manually disengaged. If used together with the
hydraulic by-pass, the machine can be moved without
using its own drive (pushed, towed away). This system of
moving may be used only when the hydraulic drive is not
functional and the machine cannot use its own drive.
- For manual manipulation with the machine secure the
brake lever by the Secure pin in position 1 (see
figure)
- For normal operation if it absolutely necessary that
the hydraulic by-pass bolt on the hydraulic pump is
tightened and the Secure pin of the auxiliary brake
released – position 2 (see figure)
Before operation, make sure that the hydraulic
pump by-pass bolt is tightened and the Secure
pin of the auxiliary drive brake released
(position 2)
Incorrect release of the auxiliary drive brake
Secure pin may lead to undesirable behaviour
of the machine on slopes, the machine may
uncontrollable drive down the slope
Daily check the brake lining. If the lining gets
thinner than 1 mm, replace it immediately.
Have the brake adjusted by an authorized
service/dealer (every 200 operating hours).
The auxiliary drive brake is designed only to
brake the wheels during the drop of pressure
in the hydraulic circuit and may not be used for
securing the machine and parking on slopes.
