Product introduction
G20 Air Pick is a high-efficiency and multi-purpose pneumatic breaking tool. It is designed with a lever-type opening and closing device, featuring strong impact force (impact energy can reach more than 50J under 0.63MPa working air pressure), compact body (total machine length 540mm), simple operation (lever-type opening and closing device design), and convenient maintenance. It is widely used in coal mines for coal mining, pillar foot pit excavation, and water channel opening; in soft rock mining; in construction and installation projects for concrete breaking and ice breaking; and in mechanical industries where impact is required, such as the loading and unloading of tractor and tank track pins.

Product feature and application
Structural features:
Compact structure: The overall weight is about 17 kilograms, and the total length is only 540 millimeters. The overall structural design is compact, integrating the air distribution mechanism, impact mechanism and pick into one, which is convenient for handheld operation.
High-efficiency impact mechanism: The 40mm cylinder diameter and 165mm hammer stroke are precisely matched power cores. Driven by compressed air, the hammer undergoes high-speed reciprocating motion to strike the tail of the pick, generating enormous impact force.
Heavy Industry Quality: Heavy industrial grade manufacturing, sturdy and durable, capable of adapting to various harsh working environment conditions.
Low air consumption and economy: Even when working at a maximum pressure of 0.63 MPa, its air consumption is controlled to be greater than 23 liters per second.
Standardized interface and universality: The inner diameter of the air hose is Φ16 millimeters, and the chisel tail handle (chisel interface) is Φ30×87 millimeters.
Application fields:
Mining operations: coal mining, soft rock mining, coal seam cutting, pillar foot trenching, water channel excavation.
Construction Engineering: Concrete Crushing, Foundation Treatment, Destruction of Original Concrete Foundation, Building Demolition.
Municipal and Road Construction: Permafrost removal, old road surface breaking, road surface repair.
Mechanical industry: Generates impact motion, such as the loading and unloading of tractors and tank track pins.
Permafrost and ice layer treatment: Permafrost breaking, ice breaking operations.
Special applications: civil air defense engineering construction, underground buildings, destruction of solid or frozen strata.
Production details
Higher safety: The independent grip-style opening and closing mechanism helps reduce accidental operation. Since opening and closing require a specific intentional pressing action, compared to some designs that may be triggered by accidental bumps, it is less likely to be accidentally activated when not in use.
More flexible operation and precise control: The starting and stopping of the jackhammer can be controlled by individual finger pressing actions, providing direct operational response and enabling more accurate control over the impact timing and rhythm. This is particularly useful in scenarios requiring frequent start/stop operations or fine manipulation, such as breaking edge concrete and avoiding damage to internal rebars.
Why choose us
1.High efficiency and performance, compact structure
Impact energy >50J, impact frequency ≥16Hz, strong power, fast working speed, can easily break hard materials such as concrete, frozen soil and soft rock. The machine body weighs about 17kg, total length 540mm, compact structure, good operability.
2.Robust design and controllability
It adopts an independent grip-type opening and closing device, which has a simple structure, low failure rate, reliable equipment, long service life, and can adapt to high-intensity and high-load working environments. Although the 17-kilogram weight requires the operator to have certain physical strength, it also ensures the stability of the equipment during impact and its ability to withstand recoil, which helps in precise operation. Its structural design has been optimized for flexible operation and can adapt to various complex working postures.
3.Wide range of scene adaptability
The real value of the G20 pneumatic pick lies in its wide range of applications. Whether it is breaking up old road surfaces in municipal engineering, cutting coal seams in mining operations, or breaking concrete foundations on construction sites, it can handle all these tasks. This versatility makes it a universal tool in many engineering fields.
FAQ
Q: What are the common faults of the G20 Air Pick and their handling methods?
A:
|
Fault |
Reason |
Exclusion method |
|
Impact frequency reduction |
1. The filter mesh at the connection pipe is blocked. |
Use compressed air to blow clean the filter wind net after unscrewing the connecting pipe. |
|
2. Blockage of the air ducts in the cylinder body and valve cabinet reduces the return speed of the hammer body. |
Disassemble the jackhammer and clean the air passages of the cylinder body and valve box. |
|
|
3. The gap between the fixed bushing and the pick tail is too large, resulting in increased air leakage. |
Check the mating clearance. When the clearance is too large, new parts should be replaced." }undefined |
|
|
The duct is blocked due to the shedding of rubber. |
Replace the damaged ductwork. |
|
|
5. Excessive wear between mating parts. |
① The gap between the cylinder body and the hammer body should not be too large. |
|
|
② The gap between the valve cabinet and the middle part of the valve should not be too large. |
||
|
The air consumption increases. |
1. Duct damage or poor splicing causes excessive leakage of compressed air. |
Repair the damaged section of the duct and connect the duct. |
|
2. The connection pipe and duct joint are not tight, leading to increased leakage of compressed air. |
Tighten the loosely connected parts. |
|
|
The hammer body and valve are jammed. |
The coupling has loosened due to wear. 3. The mating surface is rusted. |
1. Tighten the coupling sleeve or replace the worn parts. 2. Blow out the filter mesh or repair it. |
|
The parts are prone to wear. |
Impurities exist in the humid air. |
Install filters, separators and drain valves on the intake pipe of the air compressor. |
|
The pneumatic hammer cannot stop working. |
The block valve is jammed or the spring is not installed. |
Remove the pick handle, eliminate the scratches on the choke valve and choke valve sleeve, and install the spring. |
Q: When using an G20Air Pick, what technical safety standards should be noted?
A: 1.This machine is powered by compressed air. When in use, the working pressure must not exceed 0.63 MPa.
2.When used in coal mines, it is strictly prohibited to disassemble, repair the complete machine and its accessories at the working face or places where gas exists arbitrarily.
3.The connection of the compressed air hose connected to the machine should be firm and reliable to prevent faults caused by loose joints or hose rupture.
4.Safety goggles, gloves, hearing protection and other personal protective equipment must be worn when operating.
Q: What precautions should be taken when using and maintaining an G20 Air Pick?
A: 1.Pre-startup operation:Before starting the machine, check the flexibility of starting and the reliability of all related components after adding lubricating oil to the intake pipe. Ensure that the supplied compressed air is clean and that the working pressure is maintained within the recommended range (e.g., 0.63 MPa).
2.Startup and Operation: When the pneumatic hammer is working, it should initially operate at a low speed and then gradually increase the speed.
3.Loading and unloading precautions: When installing or removing valves and valve cabinets, care should be taken. Piles and collisions that may produce burrs are not allowed.
4.Equipment maintenance: For commonly used machines, regular maintenance and upkeep should be paid attention to. They should be inspected and cleaned at least once a week, with dirt inside the machine removed. Before long-term storage of pneumatic hammers, they must be disassembled, dirt on all parts removed, cleaned in kerosene, assembled with engine oil applied, and the air inlet holes and bushing holes plugged tightly. They should be placed in a dry place.
5.Safety Warning: Personnel engaged in work should take noise protection measures.
