Crown RR5700S:
Violent retract

Good day,

I have a Crown RR5725-45 that operates normally for all functions, save for the retract which bottoms out against the mast very suddenly and violently.
Don't get me wrong, the retract controls can be "Feathered" to mitigate this, but operators rarely do this...
I have several other models of Crown forklifts here, both newer and older, and this is the only machine which has this issue.
Is there a solution that can be done through software, or am I looking at a hydraulic valve issue?

Thanks in advance!

On the RR5700's you can play around with P9, P10, P11, and P14. These all have to do with the speed on the accessory hydraulics. 1 being the slowest and 9 being the fastest. If you have any mono mast reach trucks (RMD6000 or RM6000) there are performance settings where you can set it to automatically cushion.
Otherwise I would check your poly stops. If they keep slamming the reach assembly back into the mast your poly stops may be worn out causing nothing to soften the blow. These are located on the carriage assembly on the bottom. They typically are white or yellow with a hole in the middle for the bolt.
Unfortunately the best option is operator training if neither of those options above work.
