Cutting head

The velocity of cutting line matches well with the rock by the higher single cutting capacity of cutting teeth. The arrangement of cutting teeth has reached the world leading level with the strong rock breaking ability, the high cutting efficiency and the low cutting teeth consumption rate.

Efficient loading and transportation technology

The first-level transport and shovel board are driven by motors of international famous brands, with large driving force and strong transportation endurance.The shovel board is equipped with a special anti-seize device to effectively avoid the jamming phenomenon of the transport aircraft.High-strength wear-resistant plates are used in many places.

High reliability hydraulic system

Adopting the advanced hydraulic technology of construction machinery, it pioneered the hydraulic load sensitive variable pump system in roadheader industry, which has the characteristics of small calorific value, high efficiency and stable operation.

Intelligent electric control technology

According to the fault statistic analysis of several roadheader, the expert diagnosis technique is obtained.

The controller collects the working status of the roadheader in real time and displays the working status in real time. Once a fault occurs, it will display the current fault and troubleshooting methods through the expert diagnosis system for the operator to know.

No tunneling blind spot technology

Through field observation and measurement, the blind spot area account for 22.2% of the surface.The roadheader is operated by remote control and has a good operating field, which can reduce the operating blind area and the over-cut section.

Safety command system

Because of the loud noise of the roadheader, the command voice cannot be effectively conveyed. The signal command system can be selected for SANY roadheader to effectively manage the production safety.

High efficiency dust removal technology

According to the actual situation, an independent or airborne dust removal fan with large air volume can be configured, and a dry or wet dust collector can be selected. Among of them, the dry dust has a better removal effect, and after the dust removal, the dust concentration reach 0.1mg /m3. Mobile telescopic duct at cutting aspiration can be stretched according to mining methods and work period.

Automatic cable winding system

The automatic cable winding system greatly reduces the labor intensity of the workers and improves the efficiency of the roadheader.

Centralized lubrication technique

Using centralized lubrication technology, lubrication is convenient, greatly saving the time of oil filling, reducing the labor intensity of workers.

Mechanized construction

According to the improvement of product technology and the progress of tunnel construction technology, tunnel construction is gradually developing towards mechanization, automation and reduction. In the future, the mechanized construction of tunnel tunneling mainly includes the following aspects: advanced supporting multi-functional all-in-one machine, supporting facilitation after slag discharge.

Advanced research and development tool

Using Pro/E, ADAMS, ANSYS, mechanism analysis, CAPP and other research and development tools.

Using 3D software to complete the digital modeling of mechanical system;

To complete the mechanism analysis and optimization design of main moving parts;

Finite element strength analysis of the heavy parts of the machine.
