GME Series Hydraulic Drifter Introduction
Adopt the international mainstream rock drill/drifter design scheme, with a number of national patented technology, reliability, high energy efficiency, long maintenance interval cycle, good maintenance, long service life.
The unique modular design of this series of rock drill/drifter makes each module independently sealed, and equipped with a strengthened lead, which can effectively prevent the pollution of external mud water into the system, especially in the corrosive environment, to ensure the reliability and service life of the system, while in the daily maintenance and repair, disassembly and assembly operation is simple, and cylinder can be replaced separately. It greatly reduces the high maintenance cost caused by replacing the percussion shell body.
★ GME-1200 Hydraulic Drifter: Small Body, Big Power!
GME-1200 is a rock drill with smaller length of the same power in the domestic market at present, with a length of only 572mm, which can meet the needs of small section bolt support.
Percussion power is 14KW, drilling speed is fast.
Spare part service life is long and lower lost.
Enough stock of each spares to shorten the maintenance&repair time.
