Features
Cutting Head
· The velocity of the 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 its strong rock-breaking ability, high cutting efficiency, and 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 the roadheader industry, which has the characteristics of small calorific value, high efficiency and stable operation.Intelligent Electric Control Technology
· According to the fault statistical analysis of several roadheaders, the expert diagnosis technique is obtained.No Tunneling Blind Spot Technology
· Through field observation and measurement, the blind spot area accounts 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 roadheaders, the command voice cannot be effectively conveyed. The signal command system can be selected for the SANY roadheader to effectively manage production safety.High Efficiency Dust Removal Technology
· According to the actual situation, an independent or airborne dust removal fan with a large air volume can be configured, and a dry or wet dust collector can be selected. Among them, the dry dust has a better removal effect, and after the dust removal, the dust concentration reaches 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, and 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, and supporting facilitation after slag discharge.Advanced Research and Development Tool
· Using Pro/E, ADAMS, ANSYS, mechanism analysis, CAPP and other research and development tools;Specs & Compare
