When operating a hook-type shot blasting machine, ensuring safety is the top priority. This type of equipment is often used for surface treatment of small and medium-sized castings, welded parts or structural parts. Because it involves high-intensity shot impact and heavy lifting, there are many potential risks in operation. The following are the main safety precautions for operating a hook-type shot blasting machine:
1. Safety inspection before operation
Check the equipment status
Make sure that all electrical, mechanical, hydraulic and pneumatic systems are normal and without abnormalities.
Check whether the protective door, limit switch, and safety interlock device are intact and effective.
The impeller, guard plate, and shot recovery system of the shot blasting machine should not be loose or severely worn.
Check the hook and lifting mechanism
The load-bearing devices such as the hook, chain, and pulley must not have cracks or damage.
Confirm that the hook rotation and lifting system operate smoothly and the braking is reliable.
Check the shot blasting medium
Use compliant, dry, and clean steel shots.
Check that the shot storage barrel and recovery system are not blocked.
2. Safety precautions during operation
Wear personal protective equipment (PPE)
Operators must wear safety helmets, protective glasses, dust masks, protective shoes and hearing protection equipment.
Pay special attention when loading and unloading workpieces
It is forbidden to stand under the hook or contact the workpiece during lifting.
The lifting of the workpiece should be stable, the center of gravity should be centered, and overload operation is strictly prohibited.
Ensure that the safety door is closed before starting
The equipment should not be started if all safety doors (including the shot blasting room door) are not closed tightly.
Ensure that all personnel have evacuated the shot blasting room to prevent accidental injuries.
Avoid personnel from entering the dangerous area
It is strictly forbidden to open the door or enter the shot blasting room during the shot blasting operation.
It is strictly forbidden to clean, inspect or add materials to the equipment while it is running.
Immediately stop the machine for abnormal situations
Once abnormal vibration, abnormal sound, missing bullets, overload, etc. are found, the emergency stop button should be pressed immediately and the maintenance personnel should be notified to handle it.
3. Precautions after operation
Clean up residual projectiles
After the equipment is operated, the fallen projectiles should be cleaned up to prevent slipping or entering the equipment to cause secondary damage.
Power off and lock
After the operation is completed, the main power supply should be turned off and the power supply should be locked to prevent others from accidentally starting the equipment.
Regular inspection and maintenance
Establish a maintenance system to regularly inspect and maintain key parts such as shot blasting machines, lifting systems, chains, etc.
IV. Other management requirements
Specialized operation, unauthorized use is strictly prohibited
Hook-type shot blasting machine operators must undergo professional training and master equipment operating procedures and emergency handling knowledge.
Establish obvious safety signs
Safety warning signs should be set up in the shot blasting room, control panel, lifting path, etc.
Conduct safety training and drills regularly
Strengthen the safety awareness of all employees, organize emergency parking and accident drills, and improve the ability to respond to emergencies.
Summary:
Due to its structural characteristics and working intensity, the hook-type shot blasting machine involves various safety risks such as mechanical, electrical and hoisting during use. Only by strictly abiding by the operating procedures, maintaining good maintenance, ensuring that personnel are qualified and using appropriate protection can safety accidents be effectively prevented and personal and equipment safety be guaranteed.
