7655 Air-leg Rock Drill (Hand-hold Jack Hammer)
7655 Air-leg Rock Drill is one of the modern rock drilling machinery, adopting many technologiers, such as the combination of pneumactics 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 7655 Air-leg Rock Drill is with the advantages of ligh 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.
7655 Air-leg Rock Drill (Hand-hold Jack Hammer) Features:
1. Centralized operationg system, flexible startup, combination of pneumatics and water, convenient usage and maintenance.
2. Low noise, low vibration, energy-efficient, durable wearing-products, strong ability in washing blastholes and reliable.
7655 Air-leg Rock Drill, Scope of Application:
1. 7655 Air-leg Rock Drill 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.
2. 7655 Air-leg Rock Drill has a wide application scope, that it can be used to drill horizontal or tipilted blastholes on medium and dard stone, as well as vertical bolt holes on the roof. The diameter of blast holes is usually 34-42mm, and the effective depth of the hole can reach to 5 meters. 7655 is suitable with FY200B lubricator and FT160A ( or FT160B, FT170) air leg, or just on the drill rig.
G7/G20/G10 Air pick and G7/G10/G10F Pneumatic pick hammerCompared with similar types of air picks, G7 air pick (G7 Pneumatic pick hammer) 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 air pick (G10 Pneumatic pick hammer) 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 and constructing works in casting industries etc.
The main application of F20 air pick includes reinforced concrete construction, cement, permafrosr, ice, soft rock, soft mineral, road construction or other constructing works in casting industries. G20 air pick can be used in the concrete of installation works and occasions that need impact power in machinery industry like: tractor, the loading and unloading for tank track.
G10F air pick ( G10F peumatic pick hammer) is antifreezing, more suitable for working in low temperture conditions , which is mainly used in cold plateau area.
