Abstract: A modular containment system for forming a defined perimeter around liquid storage tanks or the like. The containment system generally includes a plurality of wall panels, a corner joint removably connecting adjacent corner wall panels in angular disposition, wherein the corner joint includes an anchor pad for placement beneath and for being connected to the corner wall panels, and a support unit comprised of a gusset and anchor pad for connecting and supporting the wall panels along a straight line. The wall panels, corner joint, and support unit are each preferably comprised of an integral one-piece structure and a galvanized steel material. The wall panels, corner joint, and support unit are removably connected via interlocking wedges. A liner is generally secured along an interior of the wall panels via a retaining cap. Various braces and brackets are also used to removably connect the components of the containment barrier.

Abstract: A scaffold adapted to be used with a forklift truck. The scaffold may be rotated manually 360 degrees by a worker after being lifted by the forklift. The unit is simple in construction, inexpensive, safe and easy to use.

Abstract: A low profile material carrier which, in a preferred embodiment, comprises a grain trailer with a low rear opening for dumping. Most of the load, approximately 80%, dumps through the opening under the influence of gravity. The remaining portion of the load is assisted through the opening by a unique vibrator assembly attached to an interior sloping surface of the trailer. The assembly includes an elongated vibrator bar, which extends the length of and is parallel to the downwardly sloping surface of the trailer which leads to the opening. A motor driven shaft having a plurality of eccentric weights positioned thereon is located intermediate the vibrator bar and the inclined bottom surface and is attached to the bar by a plurality of bearings. Upon actuation of the motor, the shaft, and hence the bar, are vibrated so as to serve as a direct stimulus for the emptying of the material in contact therewith.
