Abstract: The articulated off-road vehicle includes a pivotable chassis and an upper frame extending from the pivotable chassis. Wheels, an engine, and a steering assembly are coupled to the chassis, and the upper frame defines a compartment for drivers and passengers. The pivotable chassis is divided into a front chassis section and a rear chassis section, and a hinge joint pivotally connects the front chassis section to the rear chassis section. A front suspension assembly having a pair of shock absorbers respectively extending at an angle between the top corners of the upper frame and the front chassis section with the shock absorbers pivotally mounted to the upper frame and the front chassis section. Pivotal movement of the front chassis section and concurrent absorption of impact can substantially reduce impact forces imparted to the driver while traversing rough terrain as can thereby increasing safety and comfort for the driver.

Abstract: The remote controlled chemical pigging apparatus includes a housing and an inflatable device. The inflatable device contains chemicals to dissolve hardened or fossilized materials or contaminants contained within the interior portion of a pipeline, such as an oil or gas pipeline. At a specific location in the pipeline, such as at a pig apparatus receiver portion of the pipeline, the inflatable device is inflated and exploded to disperse the pipeline chemicals contained therein onto the hardened materials or contaminants that have fossilized within the pipeline. The hardened, fossilized materials or contaminants are then dissolved to liquefy the contaminants and, subsequently, to discharge the liquefied contaminants through a drain located in the pipeline. A method of cleaning a pipeline with a remote controlled chemical pigging apparatus having an inflatable device is also provided.
