Jack Hammer

Zhongrun Jack hammer is one of the modern rock drilling machinery, adopting many technologies, such as the combination of pneumatics and water, rapid telescopic air leg, pressure regulation and so on. The controller is concentrated on one handle for easier operation; in addition, the collateral quieter can optionally change the exhaust direction, lower the noise and improve the working condition. Practices have proven that our Jack hammer/Air-leg Rock Drill is with the advantages of light weight, reliability, durable wearing parts, easy maintenance etc. It is an efficient, energy saving and environmental rock drilling equipment that is quite popular to users.

Scope of Application of Jack hammer:

Jack hammer is an efficient rock drilling equipment that is mainly used in coal mining and roadway drivage, and also an indispensable tool in railway works, water conservancy construction and earthwork.

Introduction of Air Picks

Compared with similar types of air picks, G7 air pick is light, flexible and convenient and it is suitable for operating all rounds of work, especially in narrow, upper or climbing directions. It can stop working automatically when the solid object is broken. It's widely used in coal mining, soft rock, digging pits for post brackets, digging slots, breaking concrete or frozen earth in construction, installation engineering and constructing works in casting industries etc.

The type of G10 has higher efficiency and durability owing to its features of short and light, and it is easier for repair and maintenance than others.

Main application: coal mining, soft rock, digging pits for post brackets, digging slots, breaking concrete or frozen earth in construction, installation engineering or constructing works in casting industries.

G10F air pick is antifreezing, and more suitable for low temperature conditions, which is mainly used in cold plateau area.
