Drill rig rotary head for sale

Types of Rotary Heads

Drill rig rotary heads are produced in various types to meet diverse drilling situations. Here are some common types:

• K: The K series is a common type of compact motor-driven rotary head. It is used mainly in small-to-medium-sized drill rigs. This rotary head can achieve high torque and lower speeds. It is ideal for drilling through softer rock formations or for drilling in areas with limited access to larger equipment. The K series also has various models. For example, K-1 rotary head applies to F-350/F-250/EXCURSIONS, F-550, S-10, S-12, and other drilling equipment. The K-2D rotary head is suitable for D-10, D-12, D-14, D-16, D-18, D-20, D-24, D-30 drill rig, and more kinds of drilling machines.
• H: The H series utilizes a large variety of drill rigs in construction, environmental, geotechnical, and water well drilling. It has different models to fit various drill rig systems. The H series rotary heads often provide a higher level of torque than their K series counterparts, making them more suitable for drilling in harder rock formations. For instance, the H-3 rotary rig has a lot of H series rotary heads with different rigs. It is compatible with H-2, H-11, and other tooling.
• HZ: The HZ series is similar to the H series. They are high-torque, high-speed rotary heads widely applied in the geotechnical exploration drill rig market. The main difference is that the HZ series provides both manual and automatic feed cylinder options. This adaptability makes the HZ series suitable for a wider range of drilling applications. Moreover, it also allows them to penetrate various soil and rock formations effectively.
• B: The BZR series of large hydraulic rotary drilling heads are used mainly in the construction of anchored walls, deep foundations, and slop stabilization projects. They are commonly applied in globe piles or soil nail engineering. These drilling rigs are characterized by their high torque, which is transferred to the drill string through a hydraulic motor and a planetary gear system.

Specification and maintenance of drill rig rotary heads for sale

The specifications of drill rotary heads for sale vary according to soil types and customer preferences.

Some common specifications are as follows:

• Power: The horsepower for small rigs is about 275, while a big rig has a power of about 650. It could even be higher in certain cases. The power of the rotary head is extracted from the rig’s engine and drives the drill’s rotation.
• Torque: A drill head rotary’s torque value measures the twisting force of the drill. It is usually measured in pounds-feet (lb-ft). Low-torque heads can have torque as low as 20 lb-ft or even less. They are suitable for soft soils. For hard soils, rock formations, and high-density material, high-torque heads can have torque values exceeding 40,000 lb-ft.
• Speed: The speed of the drill head usually varies between 0 to 700 RPM. Speed is one of the vital factors impacting penetration and drillability. Lower speeds with higher torque are preferred in hard surfaces. Higher speeds with lower torque can be used for soft surfaces.
• Drill Diameter: Drill rig rotary heads are available in various diameters depending upon the task requirements.They can range from 6 inches to 72 inches. Some specialized models can even have a diameter of 108 inches.
• Drill Depth: The depth to which a rotary drill can work again depends upon the rig model and specifications. It can range from 10 feet to over 120 feet. The depth also depends upon the availability of casing material.
• Drill Type:As mentioned above, there are different kinds of drills. Each drill is designed to penetrate a specific type of material. For instance, tungsten carbide drills are shaped to penetrate rock formations.

Maintenance

To ensure the efficient working of the drill and its rotary head, routine maintenance is essential. Following some simple tips can always keep the machine in top working condition:

• Always lubricate the drill and its moving parts, including the bearings, chains, and gears, regularly and adequately. It minimizes wear and tear and the chances of the machine breaking down.
• Regularly check the hydraulic hoses and belts for wear and tear, bulging, cracks, or any other problem.
• Maintain the drill’s clean and paint its body at regular intervals. It prevents rust and corrosion.
• Keep the drill’s electrical connections intact and clean. Loose connections can harm the drill’s performance and functionality.
• Finally, always follow the manufacturer’s maintenance schedule. It may include periodic inspections and servicing of the drill rig.

Scenarios of drill rig rotary heads

The drill rig rotary head performs various drilling applications key to the construction industry and natural resource exploration sector.

• Ground investigation:

  The rotary drill head carries out soil and rock sampling for geotechnical analysis and environmental assessments. The gathered samples aid engineers and architects in evaluating soil composition, stability, and contamination, informing foundation design and construction planning.

• Foundation drilling:

  In the construction of deep foundations, piling, and anchor installation, the rotary drill head creates holes for piles, anchors, and caissons. It ensures precise depth control and hole diameters, enabling the insertion of structural elements that provide stability and support to buildings and infrastructure.

• Horizontal directional drilling (HDD):

  The rotary drill head facilitates HDD, a technique used to install conduits, pipelines, and cables beneath obstacles such as roads, rivers, and crowded urban areas. It creates a controlled curved borehole along which the specified material is pulled through.

• Mineral exploration and extraction:

  In the mining industry, the rotary drill head performs drilling for mineral exploration and extraction. It creates boreholes to collect rock samples for analysis, helping identify locations of economic mineral deposits. During extraction, it establishes production wells or shafts for mineral retrieval.

• Oil and gas drilling:

  In the oil and gas sector, rotary drill heads are utilized for vertical, directional, and offshore drilling. They play a crucial role in creating boreholes to access oil and gas reservoirs. Advanced rotary drill heads with specialized features are employed to enhance extraction efficiency.

• Agricultural and landscaping projects:

  Small-scale rotary drills can be used for soft soil horticulture and agriculture, such as planting trees and digging post holes. They can also drill wells for water extraction in rural and agricultural areas.

How to choose drill rig rotary head for sale

When searching for suitable rotary heads for drill rigs in the market, it is helpful to focus on specific target customers and their preferences to get better sales results. Depending on the type of customers one is trying to satisfy, it may be essential to emphasize choosing drill head rigs based on the following criteria.

• Drill Type Compatibility:

  It's crucial to ensure that the drill rig head being picked matches a specific drill type, as this creates seamless functioning between both parts. For example, some manufacturers or customers may prefer standard top drive rotary drilling heads. Others could prefer hybrid-top drive or torque-head drives. Therefore, it's essential to put compatibility first when selecting drill heads.

• Hydraulic Power Units:

  Selective hydraulic drill rig heads must also work great with various hydraulic power units. It is advised to ensure that the chosen head has a broad range of hydraulic horsepower. Additionally, the unit should have flow rate features that make them deliver efficient drilling performance.

• Gear Ratio:
