Several Points To Note When Choosing A Rotary Drilling Rig

Several points to note when choosing a rotary drilling rig. In recent years, China's rotary drilling rigs have made great progress, so the number of manufacturers of rotary drilling rigs has gradually increased. At this time, buyers are very conflicted and do not know how to make a choice. Let's talk about this with everyone.

Classification of rotary drilling rigs:

Rotary drilling rigs are divided into three types based on their main working parameters, torque, engine power, drilling diameter, drilling depth, and rig quality: wheeled rotary drilling rigs, 1-25-meter tracked rotary drilling rigs, and 25-40 meter rotary drilling rigs.

The selection of rotary drilling rig should first meet the main engineering needs of the user at present, and also take into account the potential engineering needs that may occur in the future. The performance parameters have room for development.

Wheel type rotary drilling rig

Wheeled rotary drilling rigs are generally suitable for hole piles with a diameter of 1-15 meters and a diameter of 1.2 meters or less. The machine is flexible and convenient to transfer, does not require a trailer, and can be driven directly to the construction site at close range. However, this type of wheeled rotary drilling rig also has disadvantages, such as inconvenient walking in wet and slippery areas and slow positioning speed for pile drivers.

1-25-meter tracked rotary drilling rig

Compared with the wheeled rotary drilling rig, this machine has faster drilling speed and higher efficiency. The transfer requires the use of a trailer, and the cost is higher than that of the wheeled rotary drilling rig. Customers have a strong sense of trust in it. For the same building project, customers are more likely to accept a drilling pile fee of 10000 yuan for the track, while for the wheeled drilling rig, the fee is 8000 yuan. Customers may feel that the fee is high.

25-40 meter rotary drilling rig

This type of drilling rig is twice the price of a 25 meter rotary drilling rig, and is a scaled down version of a large rotary drilling rig. Its torque, power, and other aspects are comparable to those of a large rotary drilling rig. This type of equipment is a bit cumbersome to use in rural areas, and it is not very convenient to transfer because rural roads are generally narrow. However, it is not suitable for large-scale projects.
