1. Basis
The selection criteria for a rotary drilling rig mainly include the following aspects:
1. Excavation Depth
Excavation depth is a key factor to consider when selecting a rotary drilling rig. Determine the required excavation depth based on the construction requirements and site conditions, and then select an appropriate rotary drilling rig model based on the selected excavation depth.
2. Soil Type
Soil type is a key factor in selecting a rotary drilling rig. Based on engineering geological data, determine the soil type within the project area, including soil thickness, soil quality, moisture content, toughness, and viscosity, and analyze them to select an appropriate rotary drilling rig model.
3. Construction Environment
The selection of a rotary drilling rig also requires consideration of the construction environment. When working in a building with limited space or complex surroundings, a small, flexible, and high-performance rotary drilling rig is desirable.
4. Financial Budget
Financial budget is a crucial factor in the selection process. There is a clear correlation between the price and performance of a rotary drilling rig. Select the appropriate model and configuration based on the project budget.
II. Considerations
When purchasing a rotary drilling rig, consider the following:
1. Machine Performance
A high-performance rotary drilling rig can improve work efficiency and ensure construction quality. Therefore, it's important to pay attention to various performance indicators, such as digging power, rotary torque, and rotary speed.
2. Machine Quality
When purchasing a rotary drilling rig, pay attention to machine quality. Machine quality directly affects its service life and maintenance costs. It's recommended to choose high-quality products from well-known brands and avoid low-priced products from smaller manufacturers.
3. Maintenance and Service
When purchasing a rotary drilling rig, pay attention to maintenance and service. Choose a supplier with excellent after-sales service and understand their after-sales service guarantee system, including the equipment's warranty period, service coverage, and service guarantees.
4. Safety and Stability
When choosing a rotary drilling rig, consider the machine's safety and stability. During excavation, the machine must comply with various safety regulations and recommendations, such as digging depth control and lifting safety.
5. Reliability
When purchasing a rotary drilling rig, pay attention to the machine's reliability. The machine's ability to operate stably and last for a long time directly impacts construction costs and schedules. We recommend purchasing products from large, well-known brands for their reliable quality and easy maintenance.
In general, when choosing a rotary drilling rig, you should first consider your construction needs, then select the appropriate model based on the soil type and construction environment. Finally, consider the machine's performance, quality, maintenance services, safety, stability, and reliability.
