Ok, I was unsure this was going to work with my dump truck, but it did much better than expected. Lifted a 7 ton load of fly ash with ease. My setup cannot handle a heavier load, but I can say for sure that this hydraulic pump could. This replaced my pto pump and I_ very happy with the change. It_ not super fast to raise, but it fully extends my two phase in seconds. Thanks to the seller for such a great product. I have dumped 5 large loads and several light loads so far and it works perfect every time.
