- Product Introduction
Rail Drilling machine is a kind of basic engineering equipment, mainly used in various rail drilling or sleeper drilling. It not only improves construction efficiency but also reduces labor costs.
Its main features include: first, it is efficient and reliable and can complete drilling projects of different depths and complexity. Secondly, it can also be used for construction in different materials, ZG-31I Lithium battery rail drilling machine is suitable for drilling below 75kg/m type rail. Its rail clamping device has self-locking function. It possesses features of correct borehole positioning and high drilling precision. It adopts hollow drill bit, and realizes the automatic water supply function during drilling process. It's an indispensable tool for railway maintenance, rush repair and overhaul operation of Construction Works and Electrical departments.
The advantages of drilling machines are not only reflected in engineering construction, but also in terms of economic benefits and social value. It can reduce labor costs, improve construction efficiency, and reduce construction costs; on the other hand, it can also promote the urbanization process and lay a solid foundation for social development.
Its main selling point is its high efficiency. In addition, the equipment also has a long service life and good maintenance performance, and can withstand high-intensity work intensity to ensure the depth and stability of the project.
In short, as an efficient and multi-functional engineering equipment, drilling machines will have wider applications and higher market demand in the future.
