A work machine extending in a fore-aft direction includes a frame, a ground-engaging mechanism, a boom assembly to the frame, and a traction assist apparatus. The ground-engaging mechanism is configured to support the frame on a surface. The traction assist apparatus is coupled to the boom assembly. The traction assist apparatus has an attachment point for securing a tether.

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.

A transportable container includes: a container, wherein the container comprises: two sidewalls; a front wall; and a floor; and a mating assembly, wherein the mating assembly is attached to the container and comprises: two or more rails secured to an underneath plane of the floor, wherein the two or more rails matingly engage with two or more hoist rails of a roll-off truck; two or more rear rollers; and a loading assembly. The mating assembly and the loading assembly can be attached to the container after the container has been transported from a first location to a second location. The container can thus, be re-purposed for loading, transporting, and unloading via a roll-off truck. The container can be loaded, transported, and unloaded via a cable/winch system or a hook/lift system of the roll-off truck.

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.
