Abstract: A liquid chemical applicator tank made out of ultrahigh modular weight polyethylene which has a higher volume tank by use of a tank design with a narrower front end and wider rear end over the wheels of the trailer. The tank has wheel wells over the wheels, and a series of weldments on the frame engage indented ribs in the tank to help support the tank over the wheels. The tank has a short length and width while having a large volume such that the width is less than twelve feet, eliminating special road permits, while hauling up to 2400 gallons with a 62½ inches on-center lateral length between the inside wheel assemblies. The short length and low profile allows better tracking and greater visibility. Indented ribs in the tank engage weldments on the trailer frame to eliminate straps to hold the tank on the trailer.

Abstract: A hollow walled structure (22) includes a shell (36) having a wall defining an interior compartment (46). A first support, in the form of a baffle (48), is disposed within the interior compartment (46) and engages the shell (36) at two locations (52, 54). A second support, in the form of a post (83), engages the shell (36) and extends through the interior compartment (46) to intersect the baffle (48). The shell (36), baffle (48), and post (83) are formed concurrently from a thermoplastic material by a rotational molding process. The rotational molding process can entail operations of pre-heating interior portions of the mold, delivering heat to the interior portions of the mold, and/or filling the mold with excess thermoplastic material prior to preheating the mold. The rotationally molded structure (22) has sufficient strength to function as a tank for carrying a liquid (34) in a liquid transport apparatus (20).

Abstract: A trailer and fuel tank assembly are disclosed. The fuel tank preferably forms the body of the trailer. The fuel tank may include a recess in the top surface for receiving the motor and/or pump, which may lower the pump closer to the ground to increase the suction performance of the pump.

Drain ports, positioned near the edges of the tank, can then be used to drain the contaminants from the tank. To easily attach accessories to the trailer, one or more track bars may be mounted to the trailer body. The track bars preferably include an elongate channel and an elongate slot. By placing an insert inside of the channel and bolting the accessory to the insert through the longitudinally extending slot, the accessories can be easily attached to the trailer.
