The trapezoidal piston delivers maximum impact energy to the rock and the rebound energy recovery valve matches blow energy to the rock hardness, therefore increasing production. All drilling functions are hydraulically monitored and adjusted to optimize hole straightness, accessory life, and total drilling speed. Strata-Sense drill automatics greatly reduce damage to accessories due to hole deviation. The ECM-720 top hammer hydraulic crawler drill transports easily from site to site.
