i wont be doing another chinese job...got mine dirt cheap second hand in a deal with lotsa other stuff and have had to replace both hydraulic lines and also had it spit out the release switch while a car was on it...lucky the locks worked and it was a scrap car that i got off the hoist with a forklift...spare parts not available in country..8 week wait so i told the importer what i thought of his after sales parts availability...luckily i have an old retired engineer i know and he fixed the switch for 150 bucks as against the 750 bucks for the unavailable switch with motor assembly...brand is nht development company china and distributor is superhoist in australia..
