What To Consider When Purchasing Horizontal Directional Drilling Rig

Horizontal directional drilling rig is a product often used now. It is not only convenient and simple to operate during construction, but also will not cause bad damage to the environment of the construction site. Therefore, many people will need to buy this machine. Let's talk about what we should pay attention to when buying it!

1、 Pull back force

Pullback force is one of the main technical parameters of the equipment, which basically determines the construction capacity of the equipment. The first step is to select the drilling rig with appropriate tonnage according to the engineering requirements. Horizontal directional drilling rig is a new type of drilling rig developed on the basis of fully absorbing the advantages of similar products at home and abroad. The product design is novel and unique, and the technology has reached the international advanced level. On the basis of consolidating product quality, constantly optimize the structure of R & D team, practically go deep into the construction grass-roots research, research, develop, upgrade and improve the product series, which has covered series products that meet various construction conditions and are highly humanized, such as 20 tons, 32 tons, 38 tons, 42 tons, 50 tons, 70 tons, etc.

2、 Torque

Torque is also one of the important parameters of the drilling rig. The torque determines the drilling capacity of the equipment. Generally speaking, the larger the torque is, the larger the diameter of the hole can be formed. The traveling system of our drilling rig adopts the supporting wheels, guide wheels, carrier sprockets, driving teeth and tension springs that are consistent with the excavator system, with reliable quality and better durability. The rubber track or steel track is hung with rubber track shoes, which will not damage the road surface. High torque drive motor, strong gradeability.

3、 Mud capacity

It is necessary to consider the mud channel, the capacity of the airborne mud pump and the external parallel mud interface, which determine the ability of the equipment to supply mud. In large-diameter hole forming and long-distance crossing, the mud supply capacity is an important factor to determine the success or failure of the construction. Our mud pump is a well-known brand mud pump in the industry, which has four kinds of flow and four kinds of pressure, and can be used for drilling and back dragging with different diameters. Driven by hydraulic motor, it operates stably with high output pressure and stable performance.

4、 Engine power

Engine power is a very important parameter. All the power of the equipment comes from the engine. Under special circumstances, the engine should support push-pull, rotation, mud pump and other power required by the equipment itself at the same time. Insufficient power supply in any aspect may lead to the failure of the project.
