This aerial-photography page pairs a granite-mining view with Huada's ECONETIC double blade cutting machine claims. Its value is the wider quarry context; aerial footage alone cannot verify internal components or measured performance.
Quarry-scale context
The title identifies granite mining and a double blade machine. Aerial framing may help readers understand the broad relationship between equipment and site, but the archived text does not name the quarry, country, bench or production plan. No machine model is preserved.
Structure and electrical claims
Huada says the structure uses finite-element analysis and has been stable through years of quarry practice. Electrical components are described as adapted to dust and unstable voltage, with Siemens and other recognized brands used in higher-failure-risk positions.
Permanent-magnet claim
The source presents permanent-magnet technology as an energy-saving part of an efficient granite-quarrying method. It includes no reference machine, electrical record or measured cut. Different specifications are said to be available.
