The arch anchor trolley is a kind of engineering machinery with unique characteristics. Its design and functions are aimed at improving the efficiency and quality of tunnel construction. The following will introduce the characteristics of the arch anchor trolley and its advantages in construction in detail.

   First, the arch anchor trolley has the characteristics of arch and anchor integration. After the arch frame is installed, anchor construction can be carried out without additional equipment, which greatly saves construction time and cost. Even if the surrounding rock stability is poor, system anchor construction can still be carried out, which provides convenience for construction under complex geological conditions.

   Secondly, the arch anchor trolley has high construction efficiency and low labor intensity. Only 2 operators are needed to complete the installation of 3 assembled arch frames and the welding of mesh connecting bars in 1 hour, which greatly saves human resources. Only the connecting bars and mesh of the first arch frame need to be welded to complete the connection of the entire arch frame, which simplifies the construction process and improves work efficiency.

   Thirdly, the arch anchor trolley has high construction quality. Its manipulator and anchor unit have many degrees of freedom and can be adjusted within a certain range. The error of arch frame installation is controlled within 5 cm. The anchor unit has horizontal and vertical rotation functions, which can ensure the angle and depth of the drilling, and guarantee the accuracy and quality of the construction.

   The arch anchor trolley plays an important role in tunnel construction. Its arch anchor integrated design, high-efficiency and low-consumption construction method and excellent construction quality make it an indispensable and important equipment in tunnel engineering, providing strong support for the smooth progress of the project.
