Hyster Forklift Electrical Problem
I have a Hyster forklift model ex40xl that was left in the rain and now will not go forwards or reverse. It has power and the solenoids are clicking but goes nowhere. Anyone know the problem?
Yea, you left it out in the rain. Is there power getting to the motor? Motor could have been damaged by the rain. Or maybe the battery was damaged by the rain and is not taking a full charge.
Check the brake on the motor--If it has one--The motor may be trying to turn, but the damp, sticky or swollen brake may be stuck. Have had plenty of grief and finally resolved it by storing the equipment in a heated building.
Could be corroded contacts preventing power flow. Overall sounds as if it needs a look at obvious points, like corrosion on contacts, and maybe a push in high gear to turn things over. (or real slow push) I'm not really familiar with that particular machine. Lubrication of some parts may also be called for. I am under the impression it is an electric forklifts. You say it has power? Does it for fact have all the power it needs?
More likely the forklift controller or one of the associated controls. Check the speed pot if it was full of water maybe shorted out. If so the controller will sense the short and shuts down. I don't know what model controller is in it from the model number. There is a company in York Pa called Flight Systems they will have manuals for sale to troubleshoot the control. Google it they have a web site. Will repair it if you do find the problem or provide repair parts.
I have experience with a 1976 Yale standup electric. The motor speed control produces a pulsing sound that is easily detectable. Are you seeing arcing on the main contacts? The battery cables are soldered to prevent corrosion: clamps will allow small current to flow but arc out when a large current is drawn. Also check each connector from cell to cell. The motor might also have ring terminals with corrosion causing arcing and no power. The main solenoids also have smaller contacts for forward/reverse sensing and they need to be properly aligned and clean. You probably will not see arcing from them in normal operation. Check all mechanical contacts.
It is definitely the controller. It got wet. Unplug the battery from the machine and hope the water has not caused a permanent short. Dry out the machine completely. You can either wait, or put a fan on the electronics ( gentle stream of air ) in a day or two the pressure washer will be dry and should run fine.
How Do Forklifts Work?
could somebody give access to complete repair manuals of recently launched forklift models ( electric powered & with internal combustion ) , allowing me to understand details how work the different subassemblies , sensors , electronic controls , switches ...
interesting woud be wiring diagram with the different components & items connected...
best would be a recent model of Linde or packing machine , one american : nacco or case or crown , one from Toyota or Mitshubishi .
You're asking for a lot of information that should be available on Google. Suggest you try there first, summarize your results in a table or spreadsheet, then, when you can develop specific questions, come back to CR4 and we can help. Until then, please don't expect us to do your legwork. I for one am heading to the pub for lunch and will definitely hoist a Guiness or two to you.
Have you tried contacting those manufacturers directly? Most should have downloadable manuals or guides. Good luck
forklift maintenance
what is the standard forklift running hours before it can undergo a preventive maintenance service
hi there
with the 10,500 ton i find every 20 or 30 thousand hours is good but with the smaller about 20,000 hours is good but i always check the machine before work and fill in a report then v belt can get around to it
What does the manufacturer's Maintenance Manual say about this garden tool?
well if you think about it all forklifts are diffent some needs 10,000 hours others need 20,000 and others are 100 hours it all depends on the type my advice is to talk to the people that makes it or it should be listed in the book
My propane powered Yale is 200 hrs for oil/filter change.
Hi all,
Can any one help - how to get hold of any info on forklift motors their speed controllers?
I want to get the general idea about the type of motor and controller circuit arrangements they use.
Any help appreciated.
