we provide service of enterprise's customs declaration, inspection.

Hydraulic rock drill is working efficiency is 5-10 times that of pneumatic one, while consuming 1/3 power of latter Drilling performance: applicable to hard, semi-hard and soft rocks; According to different engineering requirements, we can offer various supporting devices for different working.

Main Characteristics

Long piston helps reduce stress wave, prolong service life of piston and drill steel, and therefore increase rock drilling capability of the machine. Built-in hydraulic buffering mechanism absorbs reaction force. Conditions: manual hand-held, air ground jack, horizontal bracket for marble mining, and railway type for mines.
