Abstract: To avoid or reduce the necessity of loading a cargo container on a container carrying vehicle, for example, a cargo container 100 includes: engaging portions 101b disposed at four corners of each of upper and lower surfaces of a shell 101 and each engageable with a spreader of a container crane; and a wheel 113 capable of supporting the cargo container 100 such that the cargo container 100 is allowed to run. The wheel 113 is switchable between a runnable state where at least a lowermost portion is located below a bottom surface 101c of the cargo container 100 and supports the cargo container 100 such that the cargo container 100 is allowed to run, and a loaded state where the wheel 113 moves inward from the bottom surface 101c and the bottom surface 101c is allowed to make contact with a mount surface of the cargo container 100.

Abstract: The present invention discloses a mobile power generation system. The whole power generation system is assigned onto two conveyances. A gas turbine, a generator, an intake chamber, an exhaust collector, and an auxiliary system are disposed on a first conveyance, an intake assembly and an exhaust duct are integrally disposed on a second conveyance. The second conveyance further includes at least four lifting gears, which are configured to separate the intake assembly and the exhaust duct from the second conveyance, and jack up the intake assembly and the exhaust duct so as to accommodate the power generation transport apparatus and move it to the bottom of the intake assembly and the exhaust duct. The intake assembly and the exhaust duct are then brought down by the lifting gears to dock with the intake chamber and the exhaust collector respectively. A seal docking can be achieved by the weights of the intake assembly and the exhaust duct themselves.

Abstract: A mobile cart having a retractable wheel assembly. A control rod engages the gear mechanisms coupled to the deployment rods. As the control rod engages the gear mechanisms, the gear mechanisms rotate the deployment rods between a deployed state and a retracted state. The ends of the deployment rods that are located within each wheel base push against the top portion of each wheel housing, thereby pushing each wheel housing out and away from the wheel bases so that the mobile cart may be pushed on the exposed wheels.

Abstract: A self-loading tow dolly that permits components of the dolly to be easily removed and replaced. The tow dolly also reduces overall weight by using aluminum slotted hubs mated with 8-inch aluminum slotted wheels and by employing dissimilar materials that do not require welding and improves lubrication by providing strategically placed lubricant ports and lubricant reservoirs for rotating components.

Abstract: A dolly assembly for use in towing a disabled vehicle, preferably including a main tube with a dolly wheel mounted at each end, and a method of using same. In one preferred embodiment, the main tube is capable of selective expansion or contraction along its longitudinal axis, to facilitate adjustment and placement of dolly axle assemblies connecting opposed, generally parallel dolly assemblies. Force leveraging mechanisms may be used to aid the selective expansion or contraction of the main tube, such as ratchet or rack and pinion mechanisms. In an alternative embodiment, and for ease in transport, the dolly assembly may be pivotably collapsed along its main tube about either a vertical or horizontal axis.

Abstract: During recovery of a disabled motor vehicle, a towing dolly cradle assembly can be used to raise and carry an end of the vehicle. The towing dolly cradle assembly comprises two towing dolly assemblies spaced apart parallel to one another and with each dolly assembly having a horizontal main tube and each dolly assembly attached respectively along one of its longitudinal sides to an end of each of the two dolly axle assemblies interposed perpendicularly between the two dolly assemblies. The attachment of the two dolly assemblies to the two axle assemblies forms a generally rectangular towing dolly cradle assembly. In each dolly assembly, two pivot mounting assemblies are attached to the main tube with one mounting assembly at or near each end of the tube. Each mounting assembly has a spindle and a wheel assembly mounted to the spindle on the longitudinal side of the tube away from the interposed and attached dolly axle assemblies.
