15 Troubleshooting and fault correction
The following troubleshooting table 7 may assist you in troubleshooting. The table
does not claim to be complete.
In practice, problems may arise that cannot be considered here.
15.1 Troubleshooting procedure
Even when under time pressure, proceed in a systematic and targeted manner.
Random and unplanned disassembly and adjustment of individual values can
make it impossible to determine the original cause of a malfunction.
Get an overview of the planetary gearbox operation in connection with the
crane or the winch application.
Try to clarify whether the planetary gearbox has performed the required
function in the crane or in the winch application before the error occurred.
Try to understand the changes of the crane, winch application where the
planetary gearbox is installed:
Were there changes in the conditions of use or the area where the planetary
–
gearbox was deployed?
Has maintenance work been performed recently? Does an inspection or
–
maintenance log exist?
Have changes (e.g. conversions) or repairs been performed on the overall
–
system of the planetary gearbox? If yes: What were these?
Has the lubricating oil or the hydraulic fluid been changed?
–
Has the gear unit or the crane, the winch application been operated in
–
accordance with the intended purpose?
How is the malfunction evident?
–
Gain a clear picture of what caused the malfunction. As necessary, ask the
direct operator.
If appropriate, record the situation as you encountered it by taking digital
photographs and send these to Rexroth Customer Service.
