Hello pals... Need urgent help on fault detecting machine for heavy duty machines. My dad is a heavy mechanic, he repairs anything that uses diesel or hydraulic. From Compressors to Wireline Valves, Caterpillars, Cranes, Plants, Pressure testing pumps, etc... He works with one of the multi nationals and will like to have his own workshop. Does anyone here know about fault detecting machine for such products? And where they can be bought. Thanks guys.
