Rotary drilling rig is a heavy construction machinery that operates based on the principle of rotary cutting and drilling, and completes hole-forming operations with the assistance of auxiliary tools such as drilling buckets and casings. Its core function is to efficiently form pile holes that meet design requirements in foundation engineering. It also features fast hole-forming speed, high automation level, and wide adaptability to different stratums, making it one of the core equipments in modern foundation construction.

Its main applications include: construction engineering, transportation engineering, water conservancy engineering, energy engineering, and municipal engineering.
