20120086194 | SADDLE FRAME FOR PNEUMATIC BULK TRAILER - A saddle frame for a pneumatic bulk trailer includes first and second longitudinal saddle plates and at least one transverse support plate. Each of the saddle plates includes a front end, a rear end, an inner side, a generally arcuate upper edge, and a lower edge having at least three portions. Inwardly-directed edge flanges are formed at each portion of the lower edges. The transverse support plate extends between the inner sides of the saddle plates and is supported on an edge flange of each saddle plate. The upper edges of the saddle plates define support surfaces for engaging a pneumatic vessel of the pneumatic bulk trailer. The saddle plates are configured to be coupled to a front chassis frame and a rear chassis frame of the pneumatic bulk trailer. | 04-12-2012 |
20120067653 | STEERING DOLLY - A dolly includes a frame having a load deck for supporting a load and a plurality of axles coupled to the frame in a generally parallel relationship with wheels rotationally coupled to each side of the axles. Independent drive motors are operatively connected to each of the wheels such that the wheels can be driven completely independently from each other. This independent rotation enables the dolly to rotate in place about a vertical axis as well as minimize a turning radius of the dolly in a skid steer operation. | 03-22-2012 |
20110248474 | TOW BAR SUSPENSION SYSTEM - A tow bar suspension system includes a tow bar pivotally connected to a trailer frame, first and second mounts coupling the suspension bar to the tow bar, an elongate connector, and a coupling link. The connector couples the coupling link and the suspension bar, while the coupling link couples the connection bracket and the trailer frame. The suspension bar is angled with respect to a longitudinal axis of the tow bar such that the weight of the tow bar is applied as a torsion force on the suspension bar, which resists this force to suspend the tow bar off a ground surface. The coupling link is adjustable in length to modify the pitch of the tow bar with respect to the ground surface. | 10-13-2011 |
