1. Small horizontal directional machines
It is usually suitable for construction of some small projects or narrow spaces. It is characterized by small size, light weight, easy to carry and operate. The power is relatively small and the drilling capacity is limited, but it has advantages in laying some short-distance and small-diameter pipelines. For example, in the pipeline renovation project of old urban communities, small horizontal directional machines can flexibly carry out construction in narrow lanes, with less impact on residents' lives.
2. Medium-sized horizontal directional machines
It is widely used in municipal engineering and general pipeline laying projects. It has moderate power and drilling capacity, and can cope with construction tasks of medium length and diameter. For example, in the laying of underground pipelines on urban main roads, medium-sized horizontal directional machines can provide relatively stable drilling performance while ensuring construction efficiency.
3. Large horizontal directional machines
It is mainly used for large-scale projects or long-distance and large-diameter pipeline crossing construction. It has a powerful power system and drilling capacity, and can cross complex geological conditions. In large-scale pipeline projects such as cross-river and cross-river projects, large horizontal directional machines can play an important role in achieving long-distance precision drilling and pipeline laying.
