Product description information
- The ZG series subsoil impacters of Zhigao have a scientifically reasonable structure, which is convenient for disassembly, maintenance and repair. They can increase the effective working hours and maintain a high-efficiency and high-speed operation level. The unique heat treatment process significantly enhances the wear resistance of the workpiece surface, delays the decline in efficiency, and improves the economic performance of the product.
The piston of Zhigao's ZG series sub-bottoming impactor is equipped with a professional oil groove design, which effectively reduces the wear of the piston and significantly extends the service life of the impactor.
