A dump system (e.g., for setting in a vehicle's flatbed or trailer) includes a base, a container (for containing material) configured to pivot relative to the base, an inflate membrane coupled to the base and to the container, and a U-frame that extends around the inflate membrane and is configured to pivot relative to the base. The U-frame is configured to restrain outward expansion of the inflate membrane as the inflate membrane expands pushing on the container and causing the container to pivot upward. Some implementations include, in addition to or instead of the U-frame, a wing frame panel configured to collect and contain folds that form from material of the inflate membrane as the inflate membrane deflates and collapses (or when the inflate membrane is in a collapsed or deflated state).

A roll off trailer includes first and second trolley assemblies and a hoisting cable connected at one end to the first trolley assemble and extending about a sheave in each of the first and second trolley assemblies. The cable connects to a container. The second trolley is displaced t in a first direction while simultaneously drawing the container via the cable from the first grounded container to a second container position generally midway atop the trailer. Then, the first trolley is displaced in a second direction while simultaneously drawing the container via the cable from the second container position to a third container position generally adjacent the front of the trailer.

A bulk handling system for collecting, loading, transporting and dumping of yard waste and landscape materials such as grass clippings, yard debris, soil, mulch, stone and other dry and/or wet substances. The functions for controlling and operating the mechanical bulk handling system include a titling lift platform for filling and dumping and a gate that when open acts as a lift to move materials into the bulk container and when closed functions as a closed door. In addition to the bulk container operating in a horizontal position for transporting, which uses virtually no floor space on the platform and/or vehicle selected for use, it can also be angled downward for filling and elevated for dumping and emptying. For filling, the gate end of bulk container and lift frame can be lowered closer to the ground from a vehicle for easier and more efficient loading by an operator.

An object is to restrain a hoist shaft and a bushing of a hoist cylinder from abrading. A haulage vehicle with a pivoting vessel has a telescoping hoist cylinder provided between the vessel and the vehicle. Supply of hydraulic oil to the hoist cylinder is controlled by a valve provided between the hydraulic power source and the hoist cylinder. The haulage vehicle is provided with a bushing at one end portion of the hoist cylinder; a hoist shaft is mounted in a through bore of the bushing; a lubricant supplier supplies lubricant to a clearance between a surface of the hoist shaft and an internal surface of the through bore of the bushing; and when the vessel is seated on the vehicle, a controller controls the valve to make the hoist cylinder contract and also supply lubricant to the clearance.

The present invention discloses a frame assembly of movable stowage device and its application as a transport vehicle. The frame assembly moving stowage comprises a frame, a rolling chute, a drive sprocket, a driven sprocket, a transmission chain, a towing hook device, a towing hook guide-rail and a power device. The frame assembly can be used to load and unload a dustbin with a transfer vehicle. No special lifting equipment is required when the frame assembly is used. The automatic and modern transport vehicle of present invention makes the transportation of garbage faster and more efficient, which meets the desired requirements of logistics for the transportation of garbage.
