An Amphibious Vehicle (AV) is capable of planing with less power than prior similar size amphibious vehicles and using mostly off-the-shelf part. The AV uses an outdrive and propellor instead of a pump, and also include leading rear wheel well flaps which are spring biased forward against the hull bottom for on-road use, and pivot back to fill a gap between the hull and rear tire, reducing drag during in-water use. The combination of the propellor and wheel well flap allows planing with less horse power. An engine faces to the rear and either reversing differentials to reversing carrier and hubs provide correct wheel rotation. A reversing gear box attaches to an engine front and reverses rotation providing correct rotation for an outdrive and propellor.

Various embodiments of an amphibious submersible vehicle for use in non-destructive testing of pipe interiors and walls are disclosed herein. In one aspect, the vehicle is operable for amphibious submersible operation such that pipes of various diameters can be inspected under full, partially full, and dry conditions. In another aspect, the vehicle is equipped with a plurality of propellers for travel when fully or partially submerged in water and a plurality of wheels for traveling when in contact with a pipe wall or for traveling over debris. In some embodiments, the vehicle is equipped with a plurality of sensors configured for imaging and navigation which enable the vehicle for pipe inspection and identification of problem areas.

An amphibious vehicle has a floatable vehicle body; ground engaging propulsion structure having a plurality of ground engaging elements powered by a hydraulic motor; a fluid pump for pumping liquid manure; a power source connected to a hydraulic pump and configured to provide power to both the ground engaging propulsion structure and the fluid pump; and, remote control structure for controlling the ground engaging propulsion structure and a flow of fluid from the fluid pump. The speed and/or direction of the vehicle is remotely controllable by an operator remote from the vehicle when the vehicle is ground engaging and when the vehicle is floating.

A drilling platform for amphibious operations includes: a base, wherein drive tracks are arranged on both sides of the base, a propeller is disposed at a rear end of the base, and a driving assembly is disposed inside the base; two support cylinders are respectively disposed at two ends of the base; each of the support cylinders contains a sub-cylinder; a pushing cylinder is arranged on a bottom surface of the partition plate; a buoyancy adjustment assembly is provided at a bottom of the base, so as to provide buoyancy support for the base when the base is transferred from land to water. The present invention is suitable for drilling construction of pile foundations of water and land buildings, bridge piers, and transmission line electric tower pile foundations, as well as drilling of oil wells, wherein the drilling platform construction process at different drilling points is omitted.

An amphibious platform vehicle-vessel to support and to move hydraulically operated and controlled earth-moving and lifting equipment, such as excavators and cranes, on solid ground, semi-solid or marshy ground, shallow water, and deeper water. The modular units can be transported to a worksite on separate trailers and assembled and reconfigured on site. Two compartmented pontoon units are mounted to an adaptive cross member that can accommodate different types of moving-lifting equipment through different mounting flanges, and to auxiliary cross members. Propulsion is provided through amphibious cleats on drive chains in chain tracks driven by dual-motor driving drums and over a tension-adjusting passive chain roller, surrounding a sealed pontoon shell internally reinforced with bulkhead partitions, beam shell-bottom stiffeners, and pressed-angle shell-bottom stiffeners. An extendable auxiliary float can be extended outward from each compartmented pontoon for increased stability in floating operations. Spud units having a chain-drive spud and a spud-driving mount unit with spud-mount wear strips are hydraulically raised and lowered by a spud-driver motor at the command of the equipment operator using a spud-control switch.

The present invention is an amphibious all-terrain vehicle. This amphibious all-terrain vehicle includes a boat-shaped hull and a continuous track system that is configured to provide propulsion at multiple speeds while in water. The amphibious all-terrain vehicle includes a drive train, a suspension system having one or more tracks, an operator's station, and one or more handle bars as a steering system.

An amphibious vehicle comprises a buoyant hull, a boat motor affixed to the hull to propel the amphibious vehicle in water, two or more powered wheel assemblies affixed to the hull to propel the amphibious vehicle on land, and two or more selectively rotatable arms affixing each wheel assembly to the hull. One or more of the wheel assemblies are affixed to opposing sides of the hull. Two or more selectively rotatable arms affix each wheel assembly to the hull. The arms affixing each respective wheel assembly are selectively rotatable in unison to move the respective wheel assembly between a lowered position and a raised position.

An amphibious pumping vehicle has a floatable vehicle body, a ground engaging propulsion structure, a fluid pump, a plurality of fluid nozzles comprising a first fluid nozzle connected by a fluid conduit to the fluid pump and at least one second fluid nozzle connected to the fluid conduit, a valve structure in the fluid conduit, the plurality of fluid nozzles and the valve structure co-operating to provide directional control and motive power for the vehicle when floating, and a power source configured to provide power to both the ground engaging propulsion structure and the fluid pump.
