What Determines The Model of A Rotary Drilling Rig

The model of a rotary drilling rig is like its "ID card", carrying the core performance information of the equipment. Understanding the basis for model formulation can help users quickly determine whether the equipment is suitable for engineering requirements. Now, let's break down the key elements for you.

1. Power head torque: The power head torque is a core parameter of the model, directly reflecting the drilling capacity of the drilling rig. The greater the torque, the higher the model number is usually. For example, in "XR360", "360" mostly indicates that the maximum torque is approximately 360kN · m. This value determines the operational capacity of the drilling rig in complex strata such as hard rock.

2. Maximum hole diameter and depth: Some models may imply hole size information. For instance, "SWDM22" might correspond to a maximum diameter of 2.2 meters. The depth parameter also affects the model. The model number of deep hole drilling machines is often larger than that of shallow hole equipment, which is convenient for users to quickly match the engineering hole diameter requirements.

3. Chassis carrying capacity: The model identification of crawler chassis and tire chassis is different. Crawler chassis often start with "XR", while tire chassis may use "XRS". The greater the load-bearing capacity of the chassis, the higher the numerical grade corresponding to the model, and the stronger the self-weight of the equipment and the working intensity it can adapt to.

4. Engine power: Engine power is indirectly related to the model. The model numbers of drilling RIGS supported by high-power engines are usually larger. For instance, the power of the "280" model in the same series may be higher than that of the "200" model to ensure the stable operation of the equipment under high loads.

5. Main application scenarios: Drilling RIGS for special working conditions have exclusive model prefixes. For example, "Special for Coal mines" may be marked with "XM". The model will convey information about the suitable scenarios to the user, preventing the device from being used in unsuitable strata or environments.

6. Manufacturer-defined rules: Different brands have unique naming logics. Some incorporate research and development codes, while others use series numbers to distinguish generations. For instance, in "Yutong YTR280", "YTR" represents the brand series, while "280" refers to the general parameter system.

In conclusion, the model of a rotary drilling rig is a comprehensive reflection of its power performance, working capacity, structural features and the design concept of the manufacturer. Mastering these rules can enable more precise selection and significantly enhance construction efficiency.
