Forklift truck doesn't have enough power when driving. It has hydraulic pump HPV 75-02. Not enough Amperage on Solenoid valve for driving. When depressing pedal Amperage increase to 1000mA then starts dropping. Newer reaches 1200 mA. The same result if forklift is off the ground.
Geer pump has 23 bar.
Any idea? What else can be except maybe LHC? Some sensor??
Thanks

RPM is at max. This way works a couple of years.
Is this a new issue ? Did it run full speed previously? Does the engine run at full rpm when accelerating? Does engine rpm reach max as hyds engaged ?
Potentiometer should have between 0.93-4.13 V. In my case it has 1.03 and 4.17 V. fully depressed. Actual value i dont remember. So it's not that much off. Or? Will check again.....
But problem is that Amperage is dropping instead rising.....
If the potentiometer does not operate in its full range, the LHC controller will not supply full voltage to the solenoid valve.
It's just a little off but i don't think this could make a problem.... I've had a lot of forklifts worse position but everything worked fine. Did you have similar problem?
If you have a canbox, check the pedal position sensor. Focus on the "final stops" values.
