Hydraulic lift problem - hot hydraulic fluid

  1. Jul 19, 2012 #1
    I have hydraulic system that lift something heavier than 1 tonne. My problem is the hydraulic fluid always get so hot and sometimes because of the heat it could not lift its load (loss power). I tried to increase its flow rate and its worked for now. But it way above the permitted flow rate. I am scared that what I've done could damage the system in future. What should I do?

    Can you cool the fluid in your system?
    Alternatively, it may be that your pump is overloaded. Maybe if you reduced the hoist speed your pump would cope better.
