Based on the discussion of safety inspection standards, the following is a standardized and operational process for regular safety inspections of Concrete Laser Leveling on construction sites. This process integrates regulatory requirements, manufacturer recommendations and industry best practices, aiming to ensure the systematicness and effectiveness of the inspection. This process follows the "PDCA" cycle (Plan, Do, Check, Handle) and establishes a three-level inspection system. Establish inspection systems and archives Establish regulations: The Project Safety Department and the Equipment Department should jointly formulate the "Safety Inspection Management Measures for Concrete Laser Leveling Machines", clearly defining the inspection cycle (day, month, year), responsible person, standards (based on this process and the manufacturer's manual), and record forms. One machine, one file: Establish an independent "safety and technical file" for each piece of equipment, including: product qualification certificate, user manual, maintenance and repair manual, previous inspection records, maintenance history, operator qualifications, etc. Personnel and qualification confirmation Daily inspection responsible person: On-duty operator. Monthly inspection responsible person: Full-time equipment administrator or machine repair team leader, who must have received equipment training. Annual inspection/post-overhaul inspection responsible person: Service engineer authorized by the manufacturer or senior technician within the company. All personnel must be certified to work (operation certificate, safety training qualification certificate) and be familiar with the equipment of this model. Preparation before inspection Equipment status: Park the equipment on a flat, solid and open site, turn off the engine, remove the key, and hang a warning sign that reads "Under maintenance, Do not start". Tool preparation: Prepare the necessary tools (wrenches, multimeters, pressure gauges, laser calibration tools, etc.), safety equipment (insulating gloves, safety helmets) and record forms. A. Daily pre-operation inspection (carried out by the operator, 10-15 minutes) Objective: To ensure the basic safety and availability of the day's work. Process (in the order of circling the machine once) : Appearance and environment: Check the body for any obvious damage, oil leakage or water leakage. Safety device: Test whether the emergency stop button is sensitive and effective; Check whether the warning lights and horns are functioning properly. Laser system: Clean the laser receiver, check if the signal pole connection is firm, and power on to check if the controller display is normal. Walking and lifting: Start the engine (at low speed), and check the equipment's forward/backward movement, left and right turning, and scraper lifting smoothly without any abnormal noise under no-load conditions. Vibration unit: Start the vibrator for a short time and listen to see if the sound is uniform and if there is any abnormal noise from metal impact. Tires/Tracks: Check the tire pressure, tread wear, or the tightness and damage of the tracks. Oil: Visually inspect whether the oil levels of fuel, hydraulic oil and engine oil are within the normal range. Record: Fill in the "Daily Inspection Form" and sign to confirm. B. Monthly/every 250 hours regular inspection (carried out by the equipment administrator, 60-90 minutes) Objective: To conduct more in-depth preventive maintenance and identify potential faults. Process (deepened on the basis of daily inspection) : Hydraulic system Check all hydraulic hoses for wear, bulges, aging cracks and any leakage at the joints. Clean the vent hole of the hydraulic oil tank. While the equipment is in operation, listen for any abnormal noises from the hydraulic pump and feel the valve body for any abnormal overheating. Electrical system Check whether the main cables and sensor harnesses have any damage or indentations, and whether they are securely fixed. Clean the battery terminals, check the electrolyte level (if applicable), and tighten the connecting wires. Test whether all control switches and the functions of each channel of the remote control are normal and without delay. Machinery and Structure Use a torque wrench to recheck the tightening torque of key structural bolts (such as the hinge points of the lifting arm, the fixed seats of the vibrator, and the connection points of the frame). Check the wear condition of the scraper base plate and inspect the bearing housing of the vibrator for any oil leakage or abnormal temperature. Laser system calibration: Use a simple level to initially verify the parallelism between the scraper and the laser plane on a flat ground. Record: Fill in the "Monthly Regular Inspection Report" in detail, recording all measurement data and the problems found. C. Comprehensive inspection after annual or major overhaul (carried out by professional engineers) Objective: To fully restore the performance and safety status of the equipment and assess the overall health. Process (Systematic inspection) : Performance accuracy calibration On a standard site, professional laser emitters and measuring instruments are used to systematically calibrate and verify the elevation control accuracy and slope control accuracy of the equipment. Hydraulic system inspection Use a pressure gauge to check whether the working pressure of the main system and the pilot pressure meet the standards. Take samples of the hydraulic oil for testing and decide whether to replace it based on the results. Structural flaw detection: Non-destructive testing (such as magnetic particle testing) is carried out on welds and stress concentration areas of major load-bearing structural components. Comprehensive engine maintenance (if applicable) : Replace the three filters, inspect the belts, spark plugs/fuel injectors, and conduct exhaust gas tests. Safety function integration test: Simulate and test all safety interlocks, overload protection, and limit functions. Record: Issue authoritative "Annual Comprehensive Inspection Report" or "Certificate of Conformity for Major Overhaul and Factory Inspection", and file and preserve them. Defect classification and handling Immediate rectification items: Those that affect safety or cause immediate shutdown (such as brake failure, hydraulic pipe burst, safety device failure). It must be repaired on the spot and can only be put into use after passing the re-inspection. Planned rectification items: Those that do not affect current safe operation but require attention (such as minor oil leakage, loosening of non-critical bolts). It should be included in the maintenance plan, completed within a specified time limit, and strengthened monitoring should be carried out before rectification. Observation record item: Conditions that do not require immediate handling but need to be tracked (such as normal wear and tear). Re-inspection and acceptance After any rectification is completed, a re-inspection must be conducted by the original inspector or the person in charge of the superior to confirm that the problem has been eliminated. Fill out the "Rectification and Re-Inspection Form" to form a closed loop. Status identifier After the inspection is qualified, a "Qualified Inspection" label should be posted in a prominent position on the equipment, indicating the validity period and the inspector. For equipment that has "planned rectification items" and is still in operation, a "Limited use under working conditions" sign can be posted, clearly stating the precautions. File update: All inspection records, reports, and re-inspection forms should be promptly incorporated into the "Safety technical File" of the equipment. Data analysis: Regularly (such as quarterly) analyze the high-frequency issues in the inspection records to determine whether they are common defects or improper operation, thereby optimizing the maintenance plan or conducting targeted training. Process review: A review of the inspection process itself is conducted once a year. Based on new equipment conditions, new regulations or lessons learned from accidents, the inspection standards and items are updated. By implementing this standardized process, construction sites can minimize the safety risks of Concrete Laser Leveling, ensure personnel safety, extend equipment lifespan, and guarantee the quality of floor construction.   Note: The parameters provided in this document are for reference only and are not mandatory.
