Hello! Let's see if we can can work together to get to the root of your question!

Terex 10000 forklift with 56 foot lift. What works? Will the forklift drive forward and reverse? If it drives, will the boom lift and extend? Will it steer?

You replaced all these parts and it still will not lift load?Did you locate the main pressure relief valve and check it? Bad amin relief will keep pressure fro building and not lift.

In general it have no power of any move but lift is most important and where is the valve ?
Expert:  Curtis B. replied 8 months ago.

relief is part of the main control valve, in the inlet end of the valve, usally an adjustable valve, Spring with needle , that the more tension the higher the pressure.

Customer: replied 8 months ago.
I did all that
Expert:  Curtis B. replied 8 months ago.

That is what controls pressure. I assume the pump is turning and the drive is not stripped for the pump?

oK> Pump H as to move the fluid, the control valve sends it to each function. Relief valve controls the pressure. Have Dr appointment. got to go!

Customer: replied 8 months ago.
Thank you sir . If you can find any thing else help me
Expert:  Curtis B. replied 8 months ago.

I was thinking about what could be problem. If you loosen outlet line from the main pump, is oil clear, no air bubbles? If there is air in the discharge side of the pump, the pump may be sucking air, from a bad suction line or fitting. Any loss of suction and pump will not develop pressure and will not pump! Check the suction line and the suction filters at the tank.
