7.6 Connecting the static multiple-disk parking brake
Your planetary gearbox is/may be equipped with a static multiple-disk parking
brake to serve as parking brake.
Risk caused by the failure of the static multiple-disk parking brake!
The static multiple-disk parking brake is a safety device of the planetary gearbox.
The improper connection of the static multiple-disk parking brake or its use as
dynamic brake (using the multiple-disk parking brake for braking the vehicle) may
lead to failure or its destruction!
Operate the static multiple-disk parking brake only after a complete stop of
the, e.g. superstructure.
Always observe that the integrated multiple-disk brake that is only intended as
parking brake must be inspected and maintained by our service after dynamic
braking.
Always replace the disks, the springs and the sealing elements after a
functional impairment or thermal overload and by any repair work on the
multiple-disk parking brake.
Ensure maximum cleanliness when connecting the multiple-disk parking brake.
Make sure that neither dirt nor foreign substances penetrate in the brake
release connection.
Ensure that the brake release connection is carefully sealed.
Assemble hydraulic lines and hoses without mechanical stress.
Use e.g. copper sealing rings according to DIN 7603 as sealing means.
Make sure that no dynamic pressure occurs in the brake line.
Only use pressure fluid based on mineral oil for operating the static multiple-
disk parking brake.
Avoid contamination caused by unclean pressure fluids, rubbed-off parts or
residual dirt from system components.
Observe by all means the specifications for release pressure and maximum
brake release pressure. Also make sure that the minimum release pressure is
observed so that the multiple-disk parking brake can be completely released.
Observe by all means the specifications on the gear unit dimensioned drawing
when connecting the static multiple-disk parking brake. These can be found in
appendix D "Technical data / Drawings" of the material number-specific
operating instructions.
Danger of delayed stopping of the static multiple-disk parking brake!
Delayed application of the static multiple-disk parking brake can lead to
accidental turning of the e.g. superstructure.
Please ensure that the brake line of the static piston is pressureless within
0.5 s.
