A self propelled or trailer frame is provided with a cradle on which the tool for subterranean use can be assembled preferably in a shop protected from the weather. The tool is transported to a well site and the truck is positioned for deployment. The cradle is on a sub-frame that can translate off the end of the truck bed to get an end of the tool closer to the wellhead. The truck has a hydraulic linkage to upend the nearest end to the wellhead to a point close to where a hook in a derrick that is over the wellhead can be attached to the tool for hoisting the tool up so as to lift it off the cradle with minimal side loading on the derrick as the tool lower end leaves the cradle. The tool can be an electric submersible pump and can be used for delivery as well as removal of the tool through a wellhead.
