I put a 13' rafter boom on my tool cat. It brought up a few issues I'm wondering about.
First because of the length of the boom, the movement of the lift cylinder and bucket cylinder are WAY to fast. To the point of being just about to dangerous to use.
Is there anyway to adjust the speed of the cylinders without putting a controllable restrictor on the lines going to the cylinders?
Second. I noticed that the bucket cylinder doesn't have as much force as the lift cylinder.
By that I mean the lift cylinder can cause the bucket cylinder to "dump" or by-pass. I'm wondering if there are pressure relief valves in the system that are set to bypass a certain pressure? Maybe one or the other is not set right?
I doesn't act like the cylinder is bypassing and I'm not getting any noticeable creep with the power/unit off.
What ever it is, is very predictable and easy to duplicate. Just try to lift something too heavy with the lift cylinder and the bucket cylinder gives up.
Try lifting with bucket rotation and nothing happens. Lower the bucket/lift with no load, then rotate the the bucket and lift and the load will dump the cylinder again.
I tried to talk to the local service manager but I'm pretty sure he is married to the owners daughter. Thats the only reason I can think of that someone that useless can have that job.
Oh yeah, One other problem that just started, I haven't had a lot of time to troubleshoot. The battery keeps going dead.
I charge it up, and the unit starts and runs for about half a day then starts lighting up the alternator/battery light intermittently. Then the next time you try to start it... the battery is dead again.
I pulled the pos battery cable with the unit running and it died right away so I'm thinking the alternator isn't charging????
Don't know if the alternator is the same as most, but it isn't generating a magnetic field on the end of the center shaft when the unit is running either.
Any thought on where to start looking on that one?
Thanks for any suggestions.
