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.

The invention relates to a swim arrangement (A) for facilitating amphibious operation of a tracked vehicle (V1). Said tracked vehicle comprises a vehicle body (10) and a two track assemblies (T1, T2) suspendedly connected to the vehicle body for driving the vehicle, each track assembly (T1, T2) comprising a drive means driven endless track (4). The vehicle body comprises under structure portions (12, 14), each under structure portion (12, 14) miming over an upper side (4a) of a track (4) of a track assembly (T1, T2). Each under structure portion (12, 14) is configured to be arranged at a distance from the upper side (4a) of the track (4) during land operation of the vehicle so that a space (S1, S2) is provided. The arrangement (A) comprises means (20, 30, 100) for reducing said space (S1, S2) so as to, during swimming operation, reduce the flow of water between the under structure portion (12, 14) and the upper side (4a) of the track (4) caused when the tracks (4) are driven.

The present invention presents a vehicle that is capable of utilizing different methods of movement by rotating its propellers to accommodate air, ground, or water locomotion. The present invention includes being able to change the direction of the thrust mechanism, so that it creates thrust in the direction of flight, but it is hinged to provide full protection to the blades in the ground modality. In the case of the water implementation, these propellers are also used to provide horizontal thrust to the vessel.

A method of moving liquid manure in a liquid manure lagoon involves: driving an amphibious vehicle into the liquid manure lagoon by remotely controlling speed and direction of the amphibious vehicle on the ground, the amphibious vehicle having a ground-engaging propulsion structure for driving the amphibious vehicle on the ground and a floatable vehicle body to float the amphibious vehicle in the liquid manure lagoon; and, moving the liquid manure in the liquid manure lagoon by remotely controlling speed and direction of the amphibious vehicle in the liquid manure lagoon.

There is provided an amphibious vehicle for use on land and water comprising lateral floaters which increases the stability of the vehicle when in water. While on land, the lateral floaters may be retracted within the body of the vehicle to reduce the width of the vehicle.

An amphibious vehicle for operation in a liquid manure lagoon has a first liquid manure mover (e.g., a propeller or a nozzle) that is vertically adjustable through a closed-loop linkage assembly to change the vertical position of the first liquid manure mover with respect to the surface of the liquid manure lagoon. The vehicle has a second liquid manure mover (e.g., a propeller or a nozzle) that is angularly adjustable to adjust the orientation of the second liquid manure mover with respect to the surface of the liquid manure lagoon.

Aspects of the present disclosure generally pertain to an amphibious vehicle (or amphibian) that is viable on land as well as on water. Aspects of the present disclosure more specifically are directed toward an amphibious vehicle that employs hydrofoils and other features, for example, for efficient cruising when in water. The amphibious vehicle may be embodied as a personal amphibious vehicle.

Techniques are directed to a modular vehicle belly armor kit, as well as systems and methods which utilize such a kit. The kit includes a bottom plate, a top plate, and a plurality of wall sections connecting with the bottom plate and the top plate to form an armor structure that protects a belly portion of the vehicle. After the modular vehicle belly armor kit is positioned underneath a vehicle, the bottom plate may be placed in contact with the vehicle. After the bottom plate is placed in contact with the vehicle, the bottom plate may be fastened to vehicle.

A combination of a marsh buggy is coupled with a modified skid steer. The skid steer has a frame, and hydraulic lines for attaching to hydraulic driven motors for driving a track or wheeled drive system. The skid steer further having an engine and a hydraulic system, including a pump and hydraulic tank, and valves; an operator's cab positioned on the frame, said operator's cab further comprising a set of hydraulic controls connectable to the hydraulic system for controlling the drive system and a hydraulically driven lift system, including two booms, each boom comprising a first arm and a second arm, the first arm being pivotably mounted to the frame, the second arm being telescopically coupled to the first arm by a hydraulic cylinder controllable from the operator's cab. The marsh buggy includes a first and a second floatable pontoons, the two pontoons coupled together in a parallel but offset relationship. Each pontoon has an endless track including a chain and treads coupled around the periphery of each respective pontoon, and a series of sprockets coupled to the chain on each pontoon; each sprocket connected to a hydraulic motor. The marsh buggy further has hydraulic motors and drive sprockets coupled to the hydraulic system for driving the endless track. The skid steer is mounted on the marsh buggy, between the two pontoons, and the hydraulic motors of the marsh buggy are operationally coupled to said hydraulic system of said skid steer so that said hydraulic controls in said cab are operationally connected to said hydraulic motors to control the drive system on the marsh buggy.
