Construction method of laser leveling machine/ laser leveling flooring

  The laser transmitter of the concrete laser leveler generates a rotating laser. The laser receiver on the laser leveler receives the signal, which is analyzed by the laser measurement and control system. The deviation will be fed back to the sensitive computer control system on the laser leveler. The left and right linear actuators will adjust the height of the scraper to ensure the leveling accuracy. In today's concrete laser leveler industry, the gap between the quality of domestic laser levelers and imported and joint venture brands is getting smaller and smaller, and more and more people pay more attention to the after-sales service of the products. To improve the competitive advantage of products, high-quality products alone are no longer feasible, and more services are needed. The increasingly hot laser leveler industry can be seen at construction sites across the country. As engineering machinery, most of them face harsh working conditions, high labor intensity, long working hours, and different degrees of wear of some parts. Future maintenance problems and accessories problems require manufacturers to provide after-sales service to complete. It can be seen that good after-sales service is the foundation of guaranteeing customer interests. The market demand for domestic laser leveling machines is gradually increasing. In order to improve their competitive advantage, some manufacturers have devoted all their energy to reducing costs and prices, ignoring the quality of after-sales service. As a result, the number of manufacturers with more and more users is relatively weaker, and the after-sales service force is relatively weaker. The user's problems cannot be handled in time or even stranded for a long time. In this way, how can the company last long? The product reputation is getting worse and worse, and even if the price is lower, it will lose its competitive advantage. Shandong Vanse Machinery, as the earliest and most professional manufacturer of laser leveling machines in China, believes that occasional quality problems are not enough to deny the strength of the entire brand. Is a brand strong? The key lies in whether the company has a sound after-sales system and whether it can provide high-quality after-sales service at the first time. High-quality products are the theme of the long-term development of enterprises, and high-quality services are the key to the sublimation of corporate brand image. Shandong Vanse Laser Leveling Machine Manufacturer has been committed to the research and development and production of concrete laser leveling machine products for many years. The product quality has also been tested under various working conditions, and the high-quality after-sales service has been recognized by the majority of users. Our service tenet is that as long as there is a laser leveling machine, you only need to make a phone call, and we can always provide you with high-quality service at the first time. We insist on making high-quality products and excellent services!

    Correct operation of a concrete laser screed is key to ensuring construction quality, equipment safety, and extending its service life. Strictly adhere to the four-stage process of " Preparation → Commissioning → Operation → Finishing. " The following are detailed steps:   Clean the work surface: Remove debris such as rebar, rocks, and wood chips from the site to prevent damage to the machine chassis and scraper blades. If the ground is wet or muddy, lay down steel plates or gravel to prevent the machine from getting stuck or the tires from slipping. Confirm laser signal coverage: Check the work area for obstacles (such as scaffolding or walls) that could block the laser signal. Ensure there is no obstruction between the laser transmitter and receiver to prevent signal interruption and leveling errors. Safety precautions: Post warning signs (such as "Construction in Progress" and "Do Not Enter") around the work area to prevent non-operating personnel from entering. Operators must wear hard hats, non-slip shoes, and reflective clothing. Visual Inspection of Core Components: Structural Inspection: Check the vibrating plate and scraper for deformation or cracks, and check whether the connecting bolts (such as the vibrating frame fixing bolts) are loose. If any abnormalities are found, shut down the machine for repair. Pipe and Line Inspection: Check the hydraulic lines and connectors for leaks, check the wires for aging or damage, and check whether the laser receiver lens is clean and free of scratches. Fluid and Consumable Inspection: Fluids: Check the engine oil, hydraulic oil, and coolant levels to ensure they are within the normal range (inadequate engine oil may cause engine seizure, and insufficient hydraulic oil may cause pump wear). Fuel: Add fuel of the correct grade (according to the engine manual, usually 0# diesel). Avoid using fuel with excessive impurities that could clog the filter element. Condition of Consumable Parts: Check tire pressure (wheeled equipment) or track tightness (crawler equipment). Replace any severely worn scraper or vibrating plate wear strips.   Install the Laser Transmitter: Secure the laser transmitter on a tripod and place it near the work area (3-10 meters from the equipment to avoid vibration interference). Level the tripod so that the transmitter is level (use the transmitter's built-in level to confirm). Set the Laser Elevation: Adjust the height of the laser transmitter according to the concrete elevation specified in the construction drawings, ensuring that the laser plane aligns with the designed elevation (a tape measure can be used as an aid). Calibrating Receiver Sensitivity: Mount the laser receiver on the leveling machine's pole. After powering on the receiver, check that it is receiving the laser signal properly (a solid green light indicates normal operation; a flashing or red light indicates an abnormal signal). If the signal is unstable, reposition the transmitter or clean dust from the lens. Vibration Frequency Setting: Adjust the vibration frequency based on the concrete slump (usually between 3,000 and 6,000 vibrations per minute). For low slumps (dry, hard concrete), increase the frequency to enhance compaction; for high slumps, reduce the frequency to prevent concrete segregation. Travel Speed Adjustment: Set the travel speed based on the concrete pour thickness (usually 5-30 cm). For thicker concrete, slow down the speed (recommended 0.5-1 m/min) to ensure adequate vibration. For thinner concrete, increase the speed appropriately (1-2 m/min). Scraper Height Calibration: Use the equipment's operating lever to adjust the initial scraper height slightly above the laser mark (allowing for vibration sinkage). Before the first operation, test the speed at a corner to confirm the appropriate height.   Starting the Engine: Insert the key and power on the machine for a self-test (wait 3-5 seconds to confirm there are no fault warning lights on the instrument panel). Then, start the engine at idle speed. Avoid sudden acceleration during a cold start. Preheating the Equipment: After starting the engine, let it idle for 3-5 minutes. Observe the hydraulic system pressure (normal range: 15-25 MPa) and the water temperature gauge (operate only when the water temperature rises above 50°C at idle). Ensure there are no abnormal noises or oil leaks. Starting Operation: Shift the machine's travel gear to "Forward" and slowly push the travel joystick to smoothly enter the concrete area. Avoid sudden acceleration, which could cause the scraper to push against the concrete and create accumulations. Vibrating and Leveling: After the machine enters the concrete, turn on the vibration switch. The scraper height is automatically adjusted based on the feedback signal from the laser receiver. (When the receiver senses the laser signal, the hydraulic system drives the scraper up and down to ensure the concrete surface is aligned with the laser elevation.) During operation, maintain a straight line, with adjacent work surfaces overlapping by 5-10 cm to avoid vibration leakage. Manual leveling (using a scraper or vibrator) is required when encountering laser signal blind spots such as corners and column bases. Observe the concrete condition in real time: If honeycombing or roughness is observed on the surface, this may indicate insufficient vibration frequency or excessive travel speed, requiring prompt adjustment. If excessive water seepage occurs, pause operations and wait for the water to evaporate before resuming. Turning and reversing: When turning or exiting the work area, first turn off the vibration switch, slow down, and steer smoothly to avoid sudden turns in the concrete that could cause sanding. When reversing, ensure there are no obstacles behind you. Obtain guidance from a designated operator if necessary.   Listen: Monitor the engine, hydraulic pump, and vibrator motor for any unusual noises (such as metallic friction or high-frequency squealing). Immediately stop and inspect any abnormal noises. Observe: Check the instrument panel for normal pressure and temperature (hydraulic oil temperature should not exceed 80°C, engine water temperature should not exceed 95°C), the stability of the laser receiver signal, and any oil or fluid leaks. Measurement: Use a ruler to check the flatness of the concrete surface every 10-20 meters (the error should be ≤3mm/2m). If any deviation is found, calibrate the laser system or scraper height in time.   After the operation is completed, first turn off the vibration switch, drive the equipment to a solid ground outside the concrete area, run at idle for 3-5 minutes (let the engine and hydraulic system cool down), and then turn off the engine. Disconnect the laser transmitter power supply, disassemble the transmitter and receiver and store them properly (avoid collisions and moisture). Remove residual concrete: Use a high-pressure water gun or a shovel to clean the residual concrete on the fuselage, vibrating plate, and scraper (focus on cleaning the gaps on the bottom of the scraper and vibrating plate to prevent the concrete from solidifying and affecting the next operation), clean the surface moisture and avoid rust. Core component maintenance: Add grease to rotating parts such as vibrating bearings, walking motor gearboxes, etc. (according to the model specified in the instruction manual, such as lithium-based grease). Check whether the hydraulic pipeline joints are loose, and replace the seals in time if there is leakage; clean the dust on the surface of the air filter element (the replacement cycle needs to be shortened in dusty environments). Site Cleanup: Retrieve the laser transmitter tripod and warning signs, clean the work surface and tools, and ensure the site is clean. Short-term Storage (for same-day completion): Park the equipment on a flat, dry surface, apply the parking brake, and place wooden planks under the tires to prevent moisture. Store the laser components separately in the tool box. Long-term Storage (over 3 days): Check the fuel level in the tank (it is recommended to fill it up to reduce rust on the inner wall), turn off the main power, spray rust inhibitor on exposed metal parts, and cover with a tarp to protect from sunlight and rain.   Do not use the vibration function on non-concrete surfaces (such as hardened floors or steel plates) to avoid damage to the vibration bearings and scrapers. Prohibit Overloading: Do not exceed the equipment's maximum leveling thickness (generally ≤30 cm) or climbing angle (≤15°) to prevent overloading the hydraulic system. Do not force operation when the laser signal is interrupted. Stop the machine to troubleshoot signal issues (such as cleaning the lens or adjusting the transmitter position) to avoid height differences. Do not add fuel or check the engine oil while the engine is running to avoid fire or burns; the system pressure must be released before repairing the hydraulic system to prevent oil from spraying and injuring people.   Summary: The key to proper operation of a concrete laser screed is thorough preparation, precise control during operation, and standardized maintenance afterward. Strictly following these procedures not only ensures laser-grade surface flatness but also reduces equipment failures, extends service life, and reduces construction costs. Operators must undergo professional training and pass a professional assessment before taking up their duties. Unlicensed operation or illegal operations are strictly prohibited.     ARMOUR JOINT CONCRETE LASER LEVELING MACHINE POWER TROWEL SLIPFORM MACHINE TOPPING SPREADER STEEL FIBER  

    Let's delve into the correct methods and protective measures for long-term storage of concrete laser leveling machines (especially their precision components), such as across projects, during winter or the rainy season. This is a crucial topic. Proper storage can greatly prevent equipment from malfunctioning when it is used next time, save maintenance costs and extend its service life. Before driving the equipment into the warehouse, a thorough "physical examination" and "maintenance" must be carried out. Overall machine cleaning: Use a high-pressure water gun or steam cleaner to thoroughly remove all concrete slurry, oil stains and dust from the machine body. Focus on cleaning the accumulated materials around the tracks, scrapers and vibrators. Specialized cleaning of precision components Laser emitter/receiver: Use lens paper and blow balloons to carefully clean all lens and sensor surfaces to ensure there are no stains. Sensors and circuits: Clean the elevation sensors, tilt sensors, etc. at all parts. Thorough drying: After cleaning, park the equipment in a well-ventilated area to ensure that all components, especially electrical interfaces and precision parts, are completely dry. Compressed air can be used to dry the moisture in the gaps. Engine: Replace the engine oil and oil filter. Inject a small amount of engine oil into the cylinder and evenly distribute it by turning the crankshaft to prevent rusting inside. Fuel system: Fill the fuel tank to the brim to prevent water droplets from condensing on the inner walls of the tank and causing rust. At the same time, add fuel stabilizers to prevent diesel from deteriorating and forming gum during long-term storage. Hydraulic system Check the oil level and quality of the hydraulic oil, and replace it if necessary. Start the machine and retract all the hydraulic cylinders (such as the lifting cylinder and the leveling cylinder) to the shortest stroke state (that is, retract the piston rod into the cylinder). This is because the exposed surface of the piston rod is the most prone to rust. Lubrication and rust prevention Apply an adequate amount of grease to all lubrication points (such as pins and bearings), and squeeze out the old and potentially contaminated grease to form a new protective layer. For exposed metal surfaces, such as the base plate of the scraper and the housing of the vibrator, a thin layer of anti-rust oil or grease can be applied. Remove the batteries: It is strongly recommended to remove the batteries of the leveling and the laser emitter. Battery storage: Store the battery in a cool, dry and well-ventilated place. The ideal temperature is between 0°C and 25°C. Battery charging: Charge the battery to about 50%-70% of its capacity and store it. Perform a complete charge and discharge cycle every 1-2 months to maintain its activity and prevent permanent damage caused by "undercharging". Electrical interface: Unplug all sensor plugs, spray them with electronic contact cleaner, then cover them with dust caps or wrap them with insulating tape. Indoor priority: The best choice is a dry, well-ventilated and dust-free indoor warehouse. It can prevent exposure to the sun, rain, sudden temperature changes and dust invasion. Outdoor storage (if unavoidable) Terrain: A high, flat, solid and well-drained area must be selected to prevent the equipment from deforming due to ground subsidence or being soaked by water accumulation. Covering: Use professional waterproof and dustproof tarpaulins for covering. Avoid using ordinary plastic sheeting, as plastic sheeting is not breathable and water vapor is likely to condense inside, accelerating rusting. Make sure the tarpaulin is securely tied up to withstand strong winds. Park on a flat ground: Ensure that all tracks or tires of the equipment are steadily on the ground to release the stress on the frame. Raise the tracks/tires: Place wooden boards or rubber pads under the tracks or tires to isolate them from the wet ground and slightly release the track tension (refer to the equipment manual) to reduce rubber aging and the pressure on the load-bearing wheels. This is of Paramount importance in protecting the "brain and eyes" of the device. Laser emitter, receiver, control box It must be disassembled and put back into its original dedicated transport box. Place desiccants inside the box and replace them regularly. Store the boxes on the shelves or in safety cabinets in the warehouse, ensuring a stable temperature and humidity environment and keeping them away from any possible risks of heavy objects falling or colliding. Sensors and cables All sensors should be removed from the machine, cleaned and then placed in the drying oven as well. The cable should be coiled loosely (with a diameter of no less than 30 centimeters). It is strictly prohibited to fold it tightly or bend it excessively. It should be bound with cable ties. Hang or lay it flat on the shelf to avoid pressure. Long-term storage does not mean a one-time solution; regular inspections must be carried out. Monthly inspection: Check whether the tarpaulin is intact and if there is any leakage. Check if there is any new rust on the surface of the equipment. Check the tire/track pressure and replenish it if necessary. Perform charge and discharge maintenance on the battery. Manually rotate the tracks or move each working device several times to change the force application points of the hydraulic cylinder and bearings, preventing the seals and bearings from deforming due to long-term pressure at a single position. Project Specific measures Clean and dry Thoroughly clean the entire machine and its precision components and ensure they are completely dry. Oil and fluid management Change the engine oil, fill up the fuel and add stabilizer, and withdraw all the cylinders. Rust prevention and lubrication Apply anti-rust oil to exposed metal parts and add new grease to all lubrication points. Battery management Remove the battery, charge it to 50%-70%, store it in a cool place, and charge and discharge it regularly. Electrical system Unplug and protect all plugs, and properly wrap the cables. Storage environment First choose indoor Spaces, then outdoor high ground areas and cover them with professional tarpaulins. Equipment parking Stop on a flat ground, raise the tracks/tires, and release the tension of the tracks. Precision components It must be disassembled, placed in the original box and desiccant added, and stored safely separately. Regular inspection Check the tarpaulin, rust, battery, etc. every month and move all working devices. By following the above methods and measures, your concrete laser leveling can safely get through any long idle period. When it starts up at the next construction site, it can quickly return to its best condition and continue to create a smooth and mirror-like high-quality floor for you.   Note: The parameters provided in this document are for reference only and are not mandatory.
