A transport device for hauling a fluid load which comprises:
- a cylindrical tank adapted for containing said load;
- a front axle with a pair of wheels;
- one of said pair of wheels mounted on one end of said front axle and another one of said wheels mounted on an opposite end of said axle;
- a rear axle with another pair of wheels;
- one of said another pair of wheels mounted on one end of said rear axle and another one of said another pair of wheels mounted on an opposite end of said rear axle;
- said cylindrical tank having a horizontal axis oriented parallel to said front and rear axles;
- four hydraulic cylinders, each cylinder having a top end and a bottom end and having a ram extending out of said top end;
- a first one of said four cylinders supported by its bottom end mounted on said front axle adjacent one wheel and a second one of said four cylinders supported by its bottom end mounted on said front axle adjacent said another wheel;
- a third one of said four cylinders supported by its bottom end mounted on said rear axle adjacent said one of another pair of wheels and a fourth one of said four cylinders supported by its bottom end mounted on said rear axle adjacent said another one of said another pair of wheels;
- a pump means coupled to said four cylinders for maintaining hydraulic
- pressure in said hydraulic cylinders;
- a pair of yokes, each yoke being a panel arranged substantially parallel to one another;
- each said panel having a cutout shaped to provide that said panel straddles said tank wherein a cutout edge of each said panel abuts against and is welded to an outside surface of said tank proximal to one end of said tank opposite said other panel welded to said tank proximal to an opposite end of said tank;
- each panel comprising one of said yokes being substantially parallel to said other panel;
- a pair of baffles, each baffle having an edge;
- said edge of one of said baffles welded to an inside surface of said tank coplanar with one of said panels;
- said edge of another one of said baffles welded to said inside surface of said tank coplanar with another one of said panels;
- each one of said baffles having at least one opening to permit flow of any fluid load inside said tank;
- one of said pair of yokes being said pair of panels and having one end secured to a free end of said ram extending from said first hydraulic cylinder and another end secured to a free end of said ram extending from said third hydraulic cylinder;
- another one of said pair of yokes having one end secured to a free end of said ram extending from said second hydraulic cylinder and another end secured to a free end of said ram extending from said fourth hydraulic cylinder;
- a rear cantilever structure secured to said pair of yokes and said rear axle and extending rearward from said rear axle;
- said rear cantilever structure adapted for supporting a truck engine coupled to said rear axle;
- a front cantilever structure secured to said pair of yokes and said front axle and extending forward from said front axle configured for mounting a cab means for transporting at least one operator in said cab means;
- control means accessible to said at least one operator coupled to said engine for controlling motion of said engine;
- four pressure sensors, each one of said sensors mounted on one of said hydraulic cylinders respectively for generating a pressure signal responsive to hydraulic pressure in each one of said hydraulic cylinders;
- computer means for computing tilt of said transport device from said pressure signals.
