The planetary gearbox is a subassembly that does not require any settings or
changes in operation. The chapter of these operating instructions does therefore
not include any information on setting possibilities. Only use the planetary gearbox
within the performance range described in the technical data. The machine/vehicle
manufacturer is responsible for the correct design of the hydraulic system and its
control.
Danger of property damage and personal injury!
The static multiple-disk parking brake (parking brake) of the planetary gearbox
is a safety device. If the pressure liquid for the static multiple-disk parking brake
is contaminated, the static multiple-disk parking brake and thus the planetary
gearbox can block in undefined position. This way, the stopping function of the
static multiple-disk parking brake is no longer warranted!
f Switch off hydraulic pressure when the planetary gearbox is blocked.
f Avoid contamination caused by unclean pressure fluids, rubbed-off parts or
residual dirt from system components.
f Ensure proper installation of an emergency stop function, so that the consumer
driven machine can be brought into a safe situation.
f Always replace the disks, springs and sealing elements per axle after any
malfunction, thermal overload and during any repair work on the multiple-disk
parking brake.
If your planetary gearbox is equipped with connections for a circulating oil
lubrication or oil cooling, refer to the dimensioned drawing of the planetary gearbox
in appendix D "Technical data/drawings" of the material number-specific operating
instructions for information on the permissible operating conditions.
f Be sure to observe the permissible operating conditions.
The service life of the HYDROTRAC GFT planetary gearbox depends on the
proper assembly, installation, commissioning and application conditions, such
as for following factors, for example: speed, torque, duty cycle, operating
conditions and temperatures.
