How to perform regular maintenance on concrete laser leveling machine?

  Hand-held and ride-on: Hand-held trowels are relatively simple in structure and flexible in operation, but have lower working efficiency and are slightly cheaper; ride-on trowels are more efficient and can be equipped with two trowel discs at the same time, with a larger construction area, but are also more expensive.   Different models: Even for trowels of the same type, different models will have differences in functions and performance, which will affect the price. For example, some models of ride-on trowels are equipped with more advanced control systems, larger water tanks, more powerful engines, etc., and the price will be higher than the basic models.   Brand influence: Well-known brands usually invest more in R&D, production processes, quality control, after-sales service, etc., and the product quality and performance are more guaranteed, and the price will be relatively high. Some small or unknown brands of trowels, although the price is low, may have certain risks in terms of quality and after-sales.   Product quality: High-quality trowels perform better in terms of material selection, component precision, overall performance, etc., have longer service life, and are more expensive. For example, trowels made of high-quality manganese steel blades are more expensive than blades made of ordinary materials, and the product price will also rise accordingly.   Engine type: Common ones are gasoline engines, diesel engines, and electric engines. Gasoline engine trowels have high power and are more flexible to use, but the fuel consumption is relatively high and the price is moderate; diesel engine trowels have high torque and strong power, which are suitable for large-area, high-intensity operations, but the price is relatively high; electric trowels have the advantages of environmental protection, low noise, and low maintenance costs, but their power and endurance are limited, and the price varies depending on the battery capacity and motor performance.   Engine power: The more powerful the engine, the stronger the power it can provide, making the trowel more efficient, but it will also increase costs and lead to price increases. For example, a ride-on trowel equipped with a 24-horsepower genuine Jialing Honda gasoline engine will be more expensive than an engine with a smaller power.   Tread diameter: The larger the diameter of the trowel, the larger the area covered at one time and the higher the work efficiency, but the corresponding machine size and weight will also increase, and the price will also increase accordingly. Common trowel diameters are 1 meter, 1.2 meters, 1.5 meters, 2 meters, etc. The larger the diameter of the trowel, the higher the price of the matching trowel.   Treadblade quantity and quality: The more trowels there are, the better the troweling effect and the higher the efficiency. At the same time, a good quality spatula, such as a hardened, forged, thickened and wear-resistant manganese steel spatula, can ensure the quality and service life of the trowel, but it will also increase the cost and price of the trowel machine.   Whether to have a sprinkler: The ride-on trowel machine usually comes with an extra-large water tank and a sprinkler, which can automatically sprinkle water during the trowel process, saving manpower and improving work efficiency, but the price of the trowel machine with a sprinkler will be higher than that of the ordinary one.   Lighting system: Some trowel machines are equipped with LED front and rear lighting systems, which are convenient for operation at night or in dimly lit environments, increasing the convenience and safety of the machine, but also increasing the price.   Steering operating system: The mechanical steering operating system is responsive and easy to control, which can improve the accuracy and efficiency of the operation. The trowel machine equipped with this steering system will also be reflected in the price.   Production process: Advanced production technology can improve the production efficiency and product quality of the trowel machine, but it will also increase the production cost. For example, the use of high-precision processing equipment and strict quality inspection processes can ensure the accuracy of the components and overall performance of the trowel machine, but these will be reflected in the product price.   Raw material cost: Fluctuations in the prices of raw materials such as steel, rubber, and plastic will also affect the cost and price of the trowel machine. If the price of raw materials rises, the price of the trowel machine may also increase accordingly.   Market demand: When the market demand for concrete trowel machines is strong, the price may rise; conversely, when the market demand is insufficient, the price may fall. For example, in the peak season of construction, the demand for trowel machines is large and the price is relatively high; while in the off-season, the demand decreases and the price may be reduced.   Competition status: The degree of competition for concrete trowel machines in the market will also affect the price. If the competition is fierce, manufacturers may lower prices or provide more preferential measures in order to attract customers; if the market competition is small, manufacturers may maintain a higher price level.

In the field of construction, concrete laser levelers (concrete laser leveling machines or concrete laser levelers) have become key equipment for improving the efficiency and quality of concrete construction. With the continuous advancement of global infrastructure construction and the growing demand for high-precision construction in the construction industry, the market size of concrete laser levelers continues to expand. According to market research reports, the global market size of concrete laser levelers is expected to reach US$1.76 billion in 2025, with an annual growth rate of approximately 11.4%. In order to give full play to the effectiveness of concrete laser levelers and extend their service life, it is crucial to optimize the use environment. Before the operation of the concrete laser leveler, it is crucial to ensure that the construction site is clean and free of debris. Stones, wood, metal scraps and other debris in the site will not only hinder the normal operation of the equipment, but may also damage key components of the equipment, such as the leveling work head and walking tires. For example, if sharp stones remaining in the site are drawn into the walking mechanism of the laser leveler, it may cause the tires to be scratched and deviate, affecting the stability and walking accuracy of the equipment. At the same time, the construction site should be initially leveled so that the ground slope and undulation are within the range that the equipment can adapt to. Generally speaking, the concrete laser leveling machine is suitable for slopes within a certain range. If the site slope exceeds the specified range, it may cause the center of gravity of the equipment to be unstable, affect the leveling accuracy, and even cause safety accidents. In order to ensure the safety of construction personnel and equipment, a clear safety warning area should be set up around the concrete laser leveling machine operation area. Set up warning signs, such as "Construction site, no entry for idle people" and "Pay attention to equipment operation", and set up warning tapes to clearly divide the equipment operation range. Especially in construction sites where multiple types of work are cross-operated, prevent other personnel or equipment from mistakenly entering the operation path of the laser leveling machine to avoid collision accidents. For example, in the construction of basement floors in large commercial complexes, due to the complex construction space and frequent exchanges between personnel and equipment, a clear safety warning area can effectively reduce the probability of accidents. At the same time, arrange special personnel to be responsible for safety inspections to ensure the effectiveness of the warning area and promptly dissuade personnel and equipment from entering illegally. Response to high temperature environment: In high temperature environment, the engine of the concrete laser leveler is prone to overheating, resulting in power reduction and increased wear of parts. When the ambient temperature exceeds 35℃, the load of the engine cooling system increases significantly. At this time, the maintenance of the engine cooling system should be strengthened, and the coolant level should be checked before daily operation. If it is insufficient, add coolant that meets the specifications in time. Clean the dust and debris on the surface of the radiator regularly to ensure that the heat dissipation air duct is unobstructed. Compressed air or high-pressure water gun (pay attention to moderate water pressure to avoid damage to the radiator fins) can be used for cleaning. For example, when constructing in an open-air parking lot with high temperature in summer, if the engine temperature is found to be too high, the equipment should be immediately moved to a cool place to shut down and cool down, and never force operation under high temperature. At the same time, consider installing a sunshade for the equipment to reduce the impact of direct sunlight on the equipment and reduce heat accumulation in the engine compartment. Response to low temperature environment: In a low temperature environment (such as an ambient temperature below 5℃), the viscosity of the lubricating oil of the concrete laser leveler increases and the fluidity becomes poor, which will make it difficult to start the equipment and increase the wear of various moving parts. Therefore, before construction in a low-temperature environment, lubricating oil and hydraulic oil suitable for low-temperature working conditions should be replaced, such as using low-freezing point engine oil and hydraulic oil. Before starting the equipment, a preheating device can be used to preheat the engine, such as an electric heating water jacket, a fuel heater, etc., to improve the starting performance of the engine. At the same time, the battery of the equipment should be kept warm and protected, and a battery warming sleeve can be installed to prevent the battery from degrading due to low temperature and affecting the start of the equipment. For example, in the construction of industrial plant floors in the northern winter, taking good low-temperature protection measures for the equipment can ensure the normal operation of the concrete laser leveling machine and improve construction efficiency. High humidity environment protection: High humidity environment can easily cause the metal parts of the concrete laser leveling machine to rust and corrode, especially when constructing in coastal areas or rainy seasons. In order to cope with high humidity environments, the equipment should be parked in a dry place, and try to choose indoors or in a place with a rain shelter. If it is unavoidable to work in a humid environment, anti-rust oil can be applied to the surface of the equipment, especially parts that are prone to rust, such as the frame, chassis, and walking mechanism. Check the electrical circuits regularly to prevent short circuits caused by moisture. Use an insulation resistance tester to detect the insulation performance of the electrical circuits and deal with problems in a timely manner. For the battery of the equipment, keep it clean and dry, check the electrolyte level and density regularly, and add distilled water in time to ensure good battery performance. For example, if the laser leveling machine used for a long time in a high humidity environment does not pay attention to rust prevention, the frame may rust and reduce strength in a short time, affecting the safety and service life of the equipment. Moisture-proof measures: When the concrete laser leveling machine is idle, effective moisture-proof measures should be taken. Desiccant, such as quicklime, silica gel desiccant, etc., can be placed at the equipment parking place to absorb moisture in the surrounding air and reduce humidity. For key components of the equipment, such as laser transmitting and receiving devices, electrical control cabinets, etc., moisture-proof covers can be used for protection to prevent moisture intrusion. During construction in the rainy season, if the equipment is exposed to rain for a long time, the moisture on the surface of the equipment should be wiped dry with a dry cloth in time after the operation, and the equipment should be fully inspected to ensure that no moisture enters the equipment. For example, in the construction site in the rainy season in the south, doing a good job of moisture-proofing the equipment can effectively reduce equipment failures caused by moisture. Concrete laser leveling machines usually operate at construction sites with a lot of dust, and a large amount of dust can damage the key components of the equipment. To reduce the impact of dust, a high-efficiency air filter can be installed at the air inlet of the equipment to filter dust particles in the air and ensure that the air entering the engine and hydraulic system is clean. Clean the air filter regularly. Depending on the dust concentration at the construction site, generally clean or replace the filter element every 50-100 hours of work. At the same time, protect the laser transmitting and receiving devices of the equipment to prevent dust from adhering to the lens and affecting the transmission of the laser signal. A dust cover can be installed or the lens can be wiped regularly with a clean soft cloth. In addition, when the equipment is operating, try to avoid staying in areas with severe dust for a long time to reduce the erosion of dust on the equipment. For example, in the floor construction of a cement plant, the dust concentration is extremely high. Strengthening dust protection measures can effectively extend the service life of the concrete laser leveling machine. For electric concrete laser levelers, stable power supply is the key to the normal operation of the equipment. Before connecting to the power supply, check whether the power supply voltage meets the equipment requirements. The rated voltage fluctuation range of general equipment should be controlled within ±10%. If the voltage is too high or too low, it will affect the performance of the equipment motor and even burn the motor. You can use a voltmeter to regularly check the power supply voltage to ensure that the voltage is stable. At the same time, ensure that the capacity of the power supply line is sufficient to avoid safety accidents caused by voltage drop or line heating due to line overload. For temporary electricity use at the construction site, wiring should be carried out in accordance with relevant specifications, using a three-phase five-wire system and equipped with a leakage protector to ensure safe electricity use. For example, in the indoor floor construction of large shopping malls, if the power supply is unstable, the motor speed of the laser leveler may be uneven, affecting the leveling accuracy. Fuel-fired concrete laser levelers need to use high-quality fuel to ensure the normal operation of the engine. You should choose fuel that meets the equipment's required grades. For example, diesel engines generally use 0 or -10 diesel, and lower grades of diesel should be used in low temperature environments. Poor-quality fuel may contain impurities and moisture, which can cause the engine's fuel injectors to become clogged, combustion to be incomplete, reduce engine power, increase fuel consumption, and even damage the engine. Purchase fuel from regular gas stations and clean the fuel tank regularly to prevent impurities precipitated at the bottom of the tank from entering the fuel system. At the same time, before adding fuel to the equipment, you can use a fuel filter for secondary filtration to ensure fuel cleanliness. For example, in highway construction in remote areas, if non-standard fuel is used, the engine of the concrete laser leveler may frequently malfunction, affecting the construction progress. If conditions permit, the concrete laser leveler should be stored indoors as much as possible. Indoor storage can effectively prevent the equipment from being eroded by natural factors such as wind, sun, and rain, and reduce the risk of paint damage on the surface of the equipment and rust on metal parts. The indoor storage environment should be kept dry, well ventilated, and at a suitable temperature. The general temperature should be controlled between 5℃ – 35℃, and the relative humidity should be controlled between 40% – 70%. When storing indoors, the equipment can be parked on a dedicated bracket to avoid direct contact between the equipment and the ground, and to prevent the bottom parts from getting damp and rusting. At the same time, the equipment should be inspected and maintained regularly, such as checking the lubrication of the equipment, the connection of the electrical circuits, etc., to ensure that the equipment is in good standby condition. If the concrete laser leveling machine can only be stored outdoors, strict protective measures must be taken. First, build a rain shelter to ensure that the equipment is not directly exposed to rain. The material of the rain shelter should have good waterproof and sun-proof properties, such as color steel plates, canvas, etc. Cover the surface of the equipment with sun-proof and waterproof tarpaulin, and fix it firmly with ropes to prevent the tarpaulin from being blown away by the wind. At the same time, additional protection should be provided for key parts of the equipment, such as the engine, electrical control cabinet, laser transmitting and receiving devices, etc., which can be wrapped with a dedicated protective cover. During outdoor storage, the equipment should be inspected regularly, dust and debris on the surface of the equipment should be cleaned, and problems should be dealt with promptly. For example, in long-term outdoor construction sites, good storage protection of the equipment can effectively extend the service life of the equipment and reduce the occurrence of equipment failures.

△ Applicable stage: Before initial setting after concrete pouring (about 1-2 hours after pouring, the specific time depends on the concrete ratio and ambient temperature). △ Operation points: The laser leveler sets the reference plane through the laser transmitter, automatically levels and vibrates the concrete, and quickly completes the rough leveling of a large area. Focus on the corners, column roots and other areas that are difficult for the laser leveler to cover, and manually assist in scraping. △ Applicable stage: after the initial setting of concrete (when there is a slight indentation when pressing with fingers but it is not sticky). Operation steps: △ Disc trowel: First use a disc trowel to perform preliminary slurry lifting and compaction to eliminate surface bumps. △ Blade trowel: After the concrete strength is further improved, use a blade trowel for fine finishing to form a smooth surface. △ Note: The trowel needs to be divided into 2-3 Operate over and adjust the blade angle (from low to high) each time to gradually increase the surface density.   △ The laser leveling machine needs to complete the rough leveling before the initial setting of the concrete to avoid the difficulty of vibrating the concrete after hardening. △ The trowel machine needs to start working after the initial setting of the concrete. Too early will cause sand on the surface, and too late will make it difficult to compact. △ The laser leveling machine is responsible for efficient leveling of large areas, and the trowel machine is responsible for local finishing and surface treatment. △ For the corners that the laser leveling machine cannot reach, it is necessary to manually use a scraper to initially level it, and then the trowel machine will handle it. △ The leveling accuracy of the laser leveling machine must meet the design requirements (such as ±3mm/3m), providing a good foundation for the trowel. △ The angle and speed of the trowel blade need to be adjusted according to the strength of the concrete to avoid over-grinding or under-grinding.   Cover and maintain in time after the operation is completed to prevent surface cracking. The operation interval should be shortened in hot and dry weather to avoid excessive water loss of concrete. The laser leveling machine needs to calibrate the laser transmitter regularly, and the trowel blade needs to clean the concrete residue in time. Through reasonable process arrangement and equipment coordination, the quality and efficiency of concrete construction can be significantly improved, which is suitable for large-scale ground projects such as industrial plants, parking lots, and airport runways.
