1. Select a suitable rotary drilling rig model based on the pile foundation area being constructed, as well as the drilling diameter and depth. Generally, rotary drilling rigs are suitable for drilling depths within 50-60m and borehole diameters within 2m, with most within 1.8m.#piling rigs#
2. For machines of the same level from different manufacturers, focus on comparing three parameters: rated swing torque of the power head, single-rope lifting force of the main winch, and overall machine weight. Select a model with higher values for all three.
3. Analyze the performance-to-price ratio of the rotary drilling rig.
4. Choose a rental company with good pre-sales and after-sales service for rotary drilling rigs.
5. Understand the rated output torque of the power head, rated working pressure of the hydraulic system, and safety factor of the main winch of the rented rotary drilling rig to assess its actual capabilities and operational reliability.#piling rigs#
