• Motor grader — A heavy self-propelled construction machine, equipped with a long adjustable blade mounted between the front and rear axles, used in road construction and earthworks for grading, leveling, smoothing soil or gravel, and for snow removal.
• To self-propel — To propel oneself or move a vehicle or body by its own energetic and motor means, structurally integrated within it, without relying on an external pulling or pushing force. In transportation and aerospace engineering, it describes the ability of a device, vehicle, or projectile to generate the force required for travel by consuming a fuel or energy source stored on board.
• Self-propulsion — The act of self-propelling and its result; a technical or mechanical process through which a vehicle, projectile, or body generates its force of motion and spatial displacement utilizing an internal energy source or its own engine, without the input of an external pulling or pushing force. This structural system is fundamental in the design of rockets, spacecraft, submarines, and heavy self-propelled machinery, optimizing the operational independence of the assembly.
• Self-propelled — Self-propelled, benefiting from an engine and an internal structural energy source; a machine, vehicle, projectile, or technical system capable of autonomous movement on roads, rails, or in space, without requiring towing, pushing, or a secondary towing vehicle. In industrial and military terminology, it describes a wide range of equipment (such as howitzers, combine harvesters, or cranes) mounted on its own self-propelled chassis.
• Motorhome — A motor vehicle specially equipped as a mobile home, fully outfitted with beds, a kitchen, sanitary installations, and utilities required for living during long-distance travels or vacations. Unlike a classic caravan, it is a self-propelled structure integrated directly onto the chassis of a utility vehicle, offering complete autonomy and increased mobility to users.
• Motor scraper — A heavy, self-propelled earthmoving construction machine equipped with a large bowl and a lower cutting edge, used for digging, loading, transporting, and leveling layers of soil or aggregate over medium distances. Unlike a towed scraper, the motor scraper integrates the engine and cabin directly onto the machine's chassis, offering higher operational autonomy and maximum efficiency in major earthworks or highway construction.
• Self-propelled — Having the capability to tow, move, or propel itself using its own built-in mechanical systems and engines; self-propelled. In technical and military fields, it describes heavy machinery or artillery systems that do not require an external towing vehicle, possessing an autonomous motorized chassis.
• Self-propelled gun — A heavy artillery piece (gun or howitzer) structurally mounted on a motorized chassis, either wheeled or tracked, capable of moving autonomously and rapidly changing firing positions without requiring a separate towing vehicle. This military system offers superior tactical mobility, partial crew protection, and reduced deployment times on the battlefield.
