Rotary drilling rigs and circulating drilling rigs differ significantly, but each has its own unique characteristics and advantages. We've compared these two types of rigs in a previous article. While rotary drilling rigs aren't necessarily superior in every aspect, it depends primarily on the project. Now, let's examine the differences in their application ranges.#drilling excavator#
Many people mistakenly believe that rotary drilling rigs can drill deeper and larger holes than circulating drilling rigs. This is a misconception. Currently, the drilling depth of commercial rotary drilling rigs is limited to 60 meters. Small rotary drilling rigs, for example, can reach depths of up to 40 meters. The maximum diameter of a rotary drilling rig is limited to 2 meters or even 1.8 meters. Circulating drilling rigs, on the other hand, can reach depths of hundreds of meters and diameters of up to 3 meters, which rotary drilling rigs cannot achieve. To achieve deeper holes, the drill rod must be lengthened, which increases the weight of the drill rod and increases equipment cost, considering overall machine balance. Furthermore, drilling too deep will result in longer drilling times, significantly reducing efficiency. Circulating drills are typically used for deep pile driving in large-scale projects, but rotary drilling rigs offer advantages that circulating drills cannot, such as efficiency, environmental friendliness, relocation, and adaptability to ground conditions. These features are ideal for solving common problems in foundation construction.#drilling excavator#
Small rotary drilling rigs are also very flexible and convenient for projects like rural self-built houses, another advantage of rotary drilling rigs. Overall, each has its advantages and disadvantages, depending on the intended use.#drilling excavator#
