McKenzie had the pumps on all the trailers mounted between the landing gear and a jack shaft coming off the back of the tractor. Most customers only required one hose to off load.
Guys I always wondered do tanker drivers smoke? Are they allowed to in the cab? If hauling materials that are highly flammable? apologies for derailing.
"All persons are prohibited from smoking or carrying lighted smoking materials at any time while on or within 25 feet of such a vehicle. The word "on" includes any time while in the cab, sleeper berth, etc." Regulations Section
Just like 'nose lines'; the larger companies avoided cleaning problems like built in pumps. Last place I worked that had nose lines all the owner op needed was a short 3" 'whip' to connect the nose line to his pump and the expected two discharge hoses and we kept three 50 footers rolled up to fit spare tire racks for those 100' customers. I remember insulated aluminum [MC306] trailers for bunker oil that had an internal nose line to keep it fluid. Just a gate valve, a-nut and cap protruded. First place I worked gained a customer after another carrier snagged that protruding valve on a brick wall while turning; ripped the side of the tank open and dumped a whole load of #4 oil that ran down into a residential neighborhood which upset the receiver.
