Technical Specifications

Features

Core Features:

Strong adaptability: suitable for medium hard or hard (f=8-18) rocks, can drill horizontal, inclined, and upward boreholes, with an effective drilling depth of about 5 meters.
Efficient and energy-saving: low gas consumption, can be operated with a small air compressor; The air leg provides stable propulsion and fast footage speed.
Wet dust removal: an air-water linkage mechanism that evenly supplies water during rock drilling and discharges it in the form of rock powder slurry, improving the working environment.
Easy to operate: centralized control handle, quick retraction of air leg, simple maintenance, suitable for on-site mobile operations.
Reliable structure: It can be matched with FT-160BC air legs and can also be installed on trolleys to adapt to different working conditions.

Precautions for use:
Before homework:
Blow out impurities from the air and water pipes to prevent them from entering the machine and causing wear and tear.
Fill the oil injector with L-AN46 mechanical oil and adjust it to about 1 liter/hour. It is strictly prohibited to operate without lubrication.
Close the pressure regulating valve before ventilation to avoid injury caused by sudden extension of the air leg; Low voltage test run for 5 minutes, confirm no abnormalities before normal operation.
In the homework:
Strictly follow the principle of boiling water first and then turning on the air. At the end, turn off the water first and then turn off the air, and run for a short period of time to drain the accumulated water.
Keep the water pressure 0.1-0.15MPa lower than the air pressure to prevent water from entering the body and damaging lubrication.
Slowly operate when opening eyes, stabilize eye position, and then gradually increase speed; Personnel should stand at the side and rear, and it is strictly prohibited to face their eyes directly to prevent injury caused by broken drill rods.
Check if the Feng Shui connection is secure and avoid detachment; Adjust the air and water volume according to the rock type to avoid excessive pushing that may cause hole displacement.
After homework:
Clean the body and air leg debris, maintain regularly, inspect at least once a week, and replace damaged parts in a timely manner.
Long term storage requires disassembly, washing, oiling, and placement in a cool and dry place to avoid rusting.

Railway, tunnel, highway, metallurgy, coal mine, water conservancy and hydropower construction projects.

Rock Drills Before Use

Precautions For Use

1,Check the integrity and rotation of all parts (including rock drill, bracket, or rock drill cart) before drilling, fill necessary lubricant, and check whether the wind and waterways are smooth and whether the connection joints are firm.

2,Knock on the roof near the working face, i.e. check whether there are live rocks and loose rocks on the roof and second gang near the working face, and make necessary treatment.

3, the working surface of the flat shell hole location, is to be pounded flat in advance before allowing rock drilling, to prevent slippage or shell hole displacement.

4. It is strictly forbidden to drill dry eyes, and we should insist on wet rock drilling, turn on the water first and then the wind when operating, and turn off the wind and then the water when stopping drilling. When opening the hole, run at low speed first, and then drill at full speed after drilling to a certain depth.

5,No gloves are allowed to be worn by the drillers when drilling.

6,When using the air leg to drill the hole, pay attention to the standing posture and position, never rely on the body to pressurize, let alone stand in front of the rock drill under the work brazing rod, to prevent injury from broken brazing.

7,If abnormal sound and abnormal water discharge are found in rock drilling, stop the machine for inspection and find out the reason and eliminate it before continuing to drill.

8,When withdrawing from the rock drill or replacing the brazing rod, the rock drill can run slowly and pay attention to the position of the rock drill braze.
