How to choose a rotary drilling rig

When choosing a rotary drilling rig, you can consider the following aspects:

1. **Engineering requirements**:

  - Determine the depth, diameter and soil type (e.g. soft soil, clay, sand, etc.) to be drilled according to the specific project requirements.

2. **Equipment specifications**:

  - Choose a suitable rotary drilling rig model, paying attention to its drilling depth, diameter range, bit type and other technical parameters.

3. **Power system**:

  - Consider the power source of the equipment (e.g. diesel engine, electric motor, etc.), and whether the power and torque meet the construction requirements.

4. **Operating performance**:

  - Check the operation flexibility, stability and construction efficiency of the rotary drilling rig to ensure the performance of the equipment under different working conditions.

5. **Brand and after-sales service**:

  - Choose a well-known brand of rotary drilling rig, understand its market reputation and after-sales service guarantee, to ensure that in the process of equipment use can get timely technical support and maintenance services.

6. **Safety**:

  - Check the safety design of the equipment, such as anti-tipping and limiting devices, to ensure safety in the construction process.

7. **Technological innovation**:

  - Pay attention to the technical level and innovative functions of the equipment, such as the degree of automation, intelligent control system, etc. These can improve the construction efficiency and reduce labour costs.

8. **Budget**:

  - According to the company's budget, choose cost-effective rotary drilling rigs, taking into account the maintenance cost and service life of the equipment.

9. **User evaluations and cases**:

  - Check the evaluation and use cases of other users to understand the performance and reliability of the equipment in actual construction.

By comprehensively considering the above factors, you can better choose a rotary drilling rig that suits your project needs.
