    Concrete laser leveling are core equipment for modern, large-scale floor construction. Their proper use directly impacts the flatness, levelness, and overall construction quality of the floor. The following details four aspects: construction preparation, operating procedures, precautions, and post-construction maintenance. Proper preparation is half the battle for a successful construction project. Any negligence during this stage can lead to construction interruptions or quality defects. Compaction: The foundation base (usually a gravel or lime soil layer) must be fully compacted to prevent future settlement. Flatness: The base must be initially leveled, with minimal elevation deviation to minimize concrete waste. Cleaning and Wetting: Clean the base to ensure it is free of debris and loose dust. Before pouring concrete, the base should be moderately moistened (but not with exposed water) to prevent it from absorbing moisture from the concrete too quickly. The top elevation of the formwork must be consistent with the designed floor elevation. The formwork must be strong and stable, able to withstand the weight and vibration of the leveling and prevent deformation. The formwork must be supported straight and the joints tight. Establishing a benchmark network: Set up stable benchmark points outside the construction area according to the construction drawings. Mount the laser transmitter in the center or at a high point within the construction area, ensuring its field of view covers the entire work surface and is unobstructed. Adjust the laser transmitter to its level and design elevation. This is the key to the accuracy of the entire construction process and must be carefully calibrated by a dedicated person. Secure the laser transmitter securely to prevent movement due to vibration or impact during construction. Install protective equipment if necessary. Mix Proportion: The slump of concrete is crucial, generally recommended to be between 140-180mm. Excessive slump results in excessive fluidity, making it difficult for the laser leveling to operate; too little slump results in poor fluidity and difficulty leveling. Aggregate: The maximum aggregate particle size should be minimal (usually no larger than 25mm). Supply: Ensure a continuous supply of concrete to avoid cold joints during construction. Fuel/Battery: Check the leveling machine's fuel or battery level. Cutter Head Inspection: Check the leveling blade (cutter head) for wear and replace if necessary. Sensitivity Calibration: Start the leveling machine and check whether its laser receiver is receiving signals properly and raising and lowering the machine according to the laser plane. Perform lift and lowering tests in both manual and automatic modes to ensure sensitive and accurate response.   The concrete truck unloads the material at the construction site. Use a large rake or small excavator to initially spread the concrete to the approximate height. The pile should be slightly higher than the designed elevation (approximately 3-5 cm higher). Place the laser leveling machine astride a pre-installed formwork or on pre-paved concrete. Lower the leveling blade until it contacts the concrete surface. Turn on the laser receiver to confirm it is receiving the laser signal. The machine will then automatically adjust the blade to the precise elevation set by the laser plane. Select a mode: There are usually two modes: automatic and manual. In automatic mode, the machine automatically controls the scraper height based on the laser plane; in manual mode, the operator manually controls it. Start leveling: The scraper at the front removes any raised concrete and fills any low spots. Simultaneously, a high-frequency vibrating plate behind the leveling machine vibrates, compacts, and raises the concrete. The vibration frequency should be adjusted according to the concrete's fluidity. Travel Path: An overlapping travel path is typically used, meaning the next travel overlaps the previous travel path by approximately 10-20 cm to ensure no gaps are missed. Operator Coordination: The operator must follow the machine and monitor the concrete's condition. If any areas are short of concrete, they should be replenished manually. Excessive material should be removed promptly to avoid affecting the levelinging effect. Corners and edges where the laser leveling cannot reach require manual levelinging using a scraper (rebar) against the formwork. The level should be aligned with the machine-leveled area. For very large areas, the work should be divided into grids and constructed sequentially. The interval between adjacent grids should be controlled before the concrete begins to set.   Daily Calibration: The laser transmitter and leveling machine's measurement system must be recalibrated before each day's work. Preventing Interference: Avoid frequent movement of people or equipment in the laser path, which could interfere with the signal. Dedicated Supervision: Assign a dedicated person to supervise the laser transmitter to prevent it from being disturbed. Strictly control slump and inspect each load. Substandard concrete will be rejected. Ensure the continuity of concrete pouring to avoid cold joints. Operators must undergo professional training and hold a license. Workers on site must wear safety equipment, especially insulated shoes, to prevent electric shock and concrete corrosion and injuries to the feet. Pay attention to cables around the equipment to prevent them from being crushed. Strong winds can affect laser signal stability, so construction should be conducted with caution or suspended. High temperatures and strong winds can accelerate moisture evaporation from the concrete surface, so timely maintenance is required to prevent cracking.   After each use, the leveling must be cleaned immediately and thoroughly, especially on the scraper, vibrating plate, travel wheels, and sensors. Solidified concrete can damage the equipment and affect accuracy during the next use. When flushing, avoid direct high-pressure water jets onto delicate components such as bearings, motors, and laser receivers. Inspection and Maintenance: Regularly lubricate and maintain the engine, hydraulic system, and vibrating bearings according to the manufacturer's instructions. Check the scraper for wear and replace or rotate it promptly. Store the equipment in a dry, level area. Stow the outriggers and reduce tire pressure. Prevent rust on exposed metal parts.   Proper use of a concrete laser leveling is a systematic process, requiring meticulous preparation, precise operation, strict material control, and thorough maintenance. Following these guidelines not only significantly improves floor construction quality and efficiency (flatness can reach over 3mm/3m), but also effectively reduces labor costs and minimizes material waste, making it an indispensable process in modern floor construction.   Note: The parameters provided in this document are for reference only and are not mandatory. Due to differences in technical characteristics between different brands and models of laser levelers, please consult the manufacturer for a suitable solution before actual operation. This reference document assumes no responsibility for any issues arising from failure to follow the manufacturer's instructions.      

The application of laser leveling machine has been very extensive. It can be said that all places that need floor construction need to use leveling machine, because the effect of using leveling machine for floor construction is very good, and the ground is compacted. It is solid, flat and compact, so there are so many people who like to use laser leveling machines for work. Of course, some failures will also occur during the work of the leveling machine. Let's learn about the following two common failures. First. Overheating of hydraulic oil: If the oil temperature of the laser leveling machine hydraulic system is too high, the viscosity of the oil will decrease, the leakage will increase, the oil film of the lubricated part will be damaged, and the wear of the components will be aggravated; at the same time, the high temperature will also make the gasket made of rubber and other materials overheat. Damaged by premature aging. Therefore, it is very important to control the appropriate oil temperature. When the oil temperature is too high, the laser leveling machine must be stopped for inspection, generally starting from the following aspects: 1. Check whether the liquid level of the fuel tank is too low. Experience shows that the high oil temperature is often caused by the lack of oil in the fuel tank, so it should be replenished in time when the oil is lacking. 2. Whether the hydraulic oil filter element and the circuit are blocked. 3. Is the radiator of the laser leveling machine normal? If a large amount of dust adheres to the radiator, it can lead to poor heat dissipation and increase the oil temperature. Since the working environment of the laser leveling machine is dusty, the radiator should be cleaned in time. 4. Whether the quality of hydraulic oil is qualified. If the quality of the added oil is unqualified, it will also cause the system oil temperature to be too high. In addition, when the hydraulic system works when it is short of oil, it is easy to cause damage to the pump and motor. Therefore, after the oil shortage fault is eliminated, the operation status of the pump and motor should be checked, and the damaged parts of the pump and motor should be replaced if necessary. Second. The screw distributor does not work: Sometimes the left and right distributors of the laser leveling machine do not work, and the reason is generally that the oil replenishment system is faulty. The reasons for the low pressure of the charge oil system are: the oil inlet passage of the charge pump is not smooth; the pressure of the relief valve of the charge pump is low; the charge pump itself is faulty; the hydraulic motor is seriously leaking. Generally, the charge pump and its relief valve should be inspected mainly. Before the hydraulic oil is added to the hydraulic oil tank, it should be filled in a clean container, and the hydraulic oil must be filtered by the oil filter before being added to the hydraulic oil tank; the replacement cycle of the hydraulic oil depends on the quality of the oil used (usually every 1000h). The hydraulic oil should be kept at the working temperature; in order to ensure good heat dissipation of the hydraulic system, the hydraulic oil radiator should be cleaned regularly.
