An articulated loader has an articulated chassis and two A-frames. The points of the A-frames face each other. The articulated chassis includes a front portion and a rear portion. Likewise, there is a front or first A-frame and a rear or second A-frame. The A-frames are connected to the overall chassis at points close to but offset from the point of vehicle articulation via ball joints and via hydraulic suspension cylinders toward the wider portions of the “A”s. The vehicle is propelled along the ground by independently driven tracks. The invention includes a feature to limit the motion of the suspension system based on the load applied to the suspension cylinders, i.e., the pressure experienced by the head end of the suspension cylinders. This is accomplished via pilot operated check valves.

Mobile towers of an irrigation system have drive wheel assemblies that propel the towers along the ground. At least certain of the wheel assemblies may comprise dual wheels that share a common axis of rotation but are separately driven by their own drive motor. By driving the two separate wheels in unison but with their own individual drive shafts, increased ground-engaging surface area can be obtained without a consequential increase in load for any one motor.

An articulated loader has an articulated chassis, two A-frames, and four track assemblies. A narrow portion each of the A-frames faces a narrow portion of the other A-frame. The articulated chassis includes a front portion and a rear portion. Likewise, there is a front or first A-frame and a rear or second A-frame. The A-frames are connected to the overall chassis at points close to but offset from the point of vehicle articulation via ball joints and via hydraulic suspension cylinders toward the wider portions of the “A”s.

A laser-powered ice-penetrating communications payload delivery vehicle for sub-ice submarine missions enables under-ice operations to exchange information with terrestrial facilities or satellite networks with communications methods otherwise blocked by an ice cap. The vehicle comprises an electronics bay, a payload bay, optics bay, and a melt optic with laser. The system and method of establishing communication where the vehicle, tethered to a sub-ice vessel, is released. The vehicle ascends to the bottom of an ice sheet and uses a laser to melt the ice, forming a borehole through which the vehicle continues to ascend. When buoyancy no longer advances the vehicle beyond sea level, the vehicle continues to melt a conical opening through the ice until unobstructed atmosphere is reached and bi-directional communication is established. Where the melting capacity cannot reach ice to continue melting, the vehicle mechanically advances itself toward the surface to establish high bandwidth, bi-directional communication.

The invention provides a push wheel driving type ground sweeper which is composed of ground sweeping brushes, arc shovels, abutting plates, brush wheels, spindle belt pulleys, dust scraping brushes, a box body, a storage box, wheels, change wheels, belt pulleys and a pushing handle, wherein the ground sweeping brushes are fixed on the brush wheels along the radial direction; the widths of the brush wheels can be determined as required; the brush wheels are fixed on the spindle belt pulleys; the arc shovels are used for guide surfaces for guiding the direction of the swept garbage; shovel ports of the arc shovels are formed in the positions, in contact with a top surface, of the brush wheels; a slope is formed at the rear end of each arc shovel, and an involute distance is formed between the slope and each ground sweeping brush; and when the ground sweeping brushes roll forward, garbage and dust can be swept backward. When the push wheel driving type ground sweeper is used, the pushing handle is held by hands to push the ground sweeper to move towards the ground with garbage and dust, and then the garbage can be swept by the ground sweeping brushes; and if the ground is not cleaned, the ground sweeper can be repeatedly pushed back and forth for several times.

An articulated loader has an articulated chassis and two A-frames. The points of the A-frames face each other. The articulated chassis includes a front portion and a rear portion. Likewise, there is a front or first A-frame and a rear or second A-frame. The A-frames are connected to the overall chassis at points close to but offset from the point of vehicle articulation via ball joints and via hydraulic suspension cylinders toward the wider portions of the “A”s. The vehicle is propelled along the ground by tracks that are independently suspended. The A-frames are of approximate equal length along the axis of the vehicle and the ball joints are located as close as practical to the articulation joint. Thus, any vertical forces at the ball joints due to variations in tractive efforts for the vehicle tend to be equal and opposite in direction and to, therefore, minimize any chassis height variations.
