Rotary drilling rigs are heavy-duty machines used for drilling boreholes or wells for various purposes such as oil and gas exploration, water well drilling, foundation drilling, and geotechnical investigation. These rigs are equipped with a rotating drill bit that breaks through the surface of earth and drills to great depths. The drilling process involves rotating the drill bit using a rotary system, while a hoisting system is responsible for raising and lowering the drill string.
