A must-have for beginners: Laser leveling machine instruction manual

As construction units continue to increase their requirements for the color, appearance, and flatness of large-area concrete floors, the problems of traditional construction processes in terms of construction progress and quality are becoming increasingly prominent. The use of concrete laser leveling machines for one-time floor forming construction has far greater advantages in terms of process, technology, and cost than the former. In order to effectively improve the operating efficiency of concrete laser leveling machines, this article briefly summarizes some methods and techniques from the perspective of purchase and maintenance, hoping to help everyone's future use. ✪ How to judge whether the quality of a laser leveling machine is good? 1. Look at the effect. High-quality laser leveling machines have more stable effects. 2. Look at the speed. High-quality laser leveling machines have faster leveling speeds. 3. Look at the accuracy. High-quality concrete laser leveling machines have higher leveling accuracy. 4. Look at the model. The selection of a suitable laser leveling machine is mainly based on the construction site and area. 5. Look at the manufacturer. The technical strength of the manufacturer of concrete laser leveling machines directly affects the quality of the equipment. 6. Look at safety. When selecting a laser leveling machine, the braking performance and operational safety of the concrete laser leveling machine must also be fully considered. ✪✪How to judge whether the laser leveling machine is a new equipment? 1. Check whether there is noise during operation. Hold the inner sleeve of the bearing body of the concrete laser leveling machine with your left hand, and turn the outer sleeve with your right hand to make it rotate, and listen to whether there is noise during the operation of the bearing. Since most counterfeit products are produced under backward conditions and are completely operated in a manual workshop, it is inevitable that impurities such as dust and sand will be mixed into the bearing body during the production process, so there will be noise or unsmooth operation when the bearing rotates. 2. Check whether there is oil stain on the surface. This should be paid special attention to when purchasing. Since the current anti-rust technology is still a little behind that of foreign manufacturers, many manufacturers are prone to leave thick oil stains when anti-rusting concrete laser leveling machines, and there will always be a sticky touch when directly touching them with your hands. 3. Check whether the printing on the parts is clear. The bearing products of each laser leveling machine are usually printed with their words, numbers, etc. The counterfeit fonts are not only blurred, but also float on the surface due to the rough printing technology. Some can even be easily wiped off by hand or have serious manual traces. 4. Check whether the outer packaging is clear. Generally speaking, the concrete laser leveling machines produced by regular manufacturers have their own dedicated designers to design the outer packaging, so the whole machine packaging should be very clear from lines to color blocks. ✪✪✪How to judge whether the laser leveling machine needs overhaul? Due to the great differences in the operating conditions and maintenance levels of different concrete laser leveling machines, it is difficult to determine the reasonable overhaul time based on the service life and working time alone. According to many practical results, we recommend that the laser leveling machine generally needs an overhaul after working for 4000-6000 hours. Machinery that needs overhaul usually has the following symptoms: 1. The pipelines and sealing components of the hydraulic system are aging and the oil leakage is serious. 2. The circuits of the electronic control system are aging, the control accuracy is reduced, and the failure rate is high. 3. The engine power is significantly reduced, and symptoms such as blowby, burning oil, and difficulty in starting appear. 4. The concrete laser leveling machine has been working for about 5000 hours, but its transfer case, transmission, and reducer have never been repaired; 5. The hydraulic power of the leveling machine has decreased, which is generally manifested as insufficient walking power or material distribution power. Specifically, it is basically normal for small load operations, barely able to operate with medium loads, but unable to operate with large loads. Warm reminder: Choosing the right model and ensuring the performance of the machine are important prerequisites for the safe use of the concrete laser leveling machine, and learning maintenance skills is a necessary requirement to maintain the good operation of the laser leveling machine and extend the service life of the machine, so both aspects need to be given enough attention.

    During the maintenance of the concrete laser leveler, safety is the core premise. A full-process protection system must be established from four dimensions: personnel protection, equipment status, environmental control, and operating specifications to avoid risks such as mechanical injuries, electric shock, and falls. The following are the specific operating points:   Preparation before maintenance is the first line of defense for safety. It is necessary to ensure that "people, machines, and the environment" are all in a safe initial state: Maintenance personnel must undergo professional training and be familiar with the equipment structure (such as laser transmitter, leveling scraper, hydraulic system), electrical principles and safe operating procedures. Unlicensed or non-professional operation is strictly prohibited. Head Protection: Wear an impact-resistant helmet to prevent injuries from falling equipment parts or tools. Hand Protection: Wear non-slip, wear-resistant gloves to avoid contact with sharp parts and oily surfaces. Wear insulating gloves when operating electrical equipment. Foot Protection: Wear impact-resistant and puncture-resistant safety shoes to prevent injuries from being crushed by the equipment or punctured by debris on the ground. Eye Protection: Wear goggles to prevent eye splashes when cleaning equipment dust or checking hydraulic fluid. Other: If welding or cutting is involved, wear a welder's mask and flame-retardant clothing. First, park the equipment on level, firm, and flat ground (to prevent it from sliding), shut off the engine, and remove the key. Disconnect the main power switch (battery switch or main power switch) and hang a "Maintenance in Progress, Do Not Close" warning sign at the switch. Lock the equipment if necessary (keys should be kept by maintenance personnel). Discharge residual energy from the equipment: For hydraulic systems, fully retract the cylinders by operating the joysticks to release hydraulic pressure. Pneumatic components should be depleted from their air tanks. Capacitive components should be discharged to prevent electric shock. Check that moving parts (such as leveling wheels and scrapers) are in the "non-operating" position. Use wedges to wedge the wheels if necessary (especially when performing maintenance on slopes to prevent the equipment from rolling). Clear the maintenance area of ​​any obstructions (such as rebar, gravel, and tools). Designate a "safe work zone" of at least 1.5 meters, prohibiting unauthorized personnel from entering (warning tape or signs may be used). Check the environment for potential risks: Avoid performing electrical system maintenance in rainy or humid conditions (to prevent short circuits and electric shock). If performing maintenance in a confined space (such as an underground garage), ensure adequate ventilation (to prevent engine exhaust poisoning). Ensure adequate lighting (at least 50 lux) for nighttime maintenance.   During maintenance, specific safety measures must be implemented based on the characteristics of the equipment's key systems (electrical, hydraulic, and mechanical): It is strictly forbidden to remove electrical components (such as the laser controller and junction box) while the device is energized. Use a multimeter to confirm that the circuit is free of voltage before proceeding. When replacing wires or sensors, use parts that meet the original manufacturer's specifications (e.g., insulation rating of at least IP67). Connectors must be waterproof and sealed to prevent rainwater from seeping in and causing a short circuit. If using power tools (such as drills and multimeters), ensure the insulation is intact, use a socket with a residual current protection (leakage current ≤ 30mA), and operate the tool with one hand to minimize the path of current passing through the body in the event of an electric shock. Hydraulic oil should be checked 15 minutes after the equipment has been shut down (after the system pressure has been completely released). Never remove joints while hydraulic lines are pressurized (high-pressure oil spray can reach 100 m/s and can easily pierce skin). When removing hydraulic components (such as cylinders and pumps), wrap joints with a rag to prevent oil splashing and contamination, and to buffer residual pressure. When refilling hydraulic oil, use a filter to prevent impurities from entering the system, and keep the oil level below the tank mark to prevent leakage caused by excessive oil temperature. If the hydraulic oil has a pungent odor or is cloudy, replace it immediately to prevent wear and bursting of the hydraulic pump. When inspecting rotating components such as leveling wheels and scrapers, manually rotate them to ensure they are not stuck. Do not use tools to pry (to prevent sudden rotation and pinching of fingers). When tightening bolts (such as frame bolts), use a torque wrench to the factory-specified torque (with a torque tolerance of ±5% to prevent breakage or loosening). Do not stand directly over the bolts (to prevent the wrench from slipping and causing injuries). When replacing worn parts (such as scraper blades), secure the components with a bracket to prevent them from falling. When removing sharp parts, wrap the edges with a cloth to prevent cuts.   After maintenance is completed, a systematic inspection is required to ensure the equipment has returned to a safe operating state and avoid subsequent accidents caused by improper maintenance. First, conduct a no-load test run: Start the equipment and test the laser positioning, screed wheel rotation, and scraper lift functions in sequence. Observe that all components operate smoothly (no abnormal noise or vibration) and that there are no leaks in the hydraulic lines (no more than one drop of oil in 10 minutes). During the test run, an observation area should be set up around the equipment, with maintenance personnel standing to the side (avoiding direct contact with rotating components). If any abnormalities are detected (such as laser deviation or unusual noise), the equipment should be shut down and powered off for inspection immediately. Site Cleanup and Recording Clean oil, tools, and accessories from the maintenance area, and store hazardous waste such as waste oil and filters in a classified manner (hand them over to qualified personnel for disposal; dumping is strictly prohibited). Remove the "Maintenance in Progress" sign. Before turning off the power switch, re-confirm that all maintenance personnel have evacuated the equipment area to prevent accidental startup and injury. Fill out the Maintenance Record Form, recording maintenance items, replaced parts, test results, and other information (for easy traceability. If loose bolts are found, check for insufficient torque). Maintenance personnel must clean their bodies (especially areas that have come into contact with hydraulic oil or rust inhibitors to prevent skin allergies) and check that their protective equipment is intact (for example, gloves are not damaged and can be used again during the next maintenance session). If minor scratches or electric shocks occur during maintenance, work must be stopped immediately and emergency treatment must be implemented (such as flushing the wound with saline solution and applying iodine. After an electric shock, rest and observe for 30 minutes). In serious cases, seek medical attention immediately.   Regular Safety Training: Quarterly, maintenance personnel will review the "Equipment Safety Operating Procedures" and conduct simulated emergency scenarios such as electric shock and hydraulic leaks (e.g., using an insulated rod to disconnect live wires and sealing oil leaks with cotton cloth). Equipment Safety Inspections: A "three-minute safety inspection" must be conducted daily before starting the equipment (checking the brakes, lights, and warning bells for proper function). Monthly functional tests of safety devices (e.g., emergency stop buttons and seat belts) must be conducted (all power must be immediately disconnected if the emergency stop button is triggered). Emergency Supplies: Equipment storage areas must be equipped with a first aid kit (including tourniquets, burn ointment, and insulated gloves), a fire extinguisher (ABC dry powder type, for electrical or oil fires), and emergency lighting (with a battery life of at least 4 hours). In short, the safety of concrete laser leveling machine maintenance must run through the entire process of "before – during – after", and the core is "respecting risks and strictly abiding by regulations" – you must be familiar with the characteristics of the equipment and pay attention to the details of personnel protection to fundamentally prevent safety accidents. 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.

Can a laser leveler be used to make a "three super" floor? The "three super" floor is the ideal goal we have always wanted to achieve, but there is no way to achieve this standard with traditional operation methods. After all, the continuity of manual operations is not strong and it is very prone to operational errors. Can the laser leveling machine meet the standard of this "three super" floor?   The so-called "three supers" are super flat, super strong and super provincial. Since the 1990s, since the continuous promotion of "clear water concrete" (building) ground and colored wear-resistant (building) ground, after several years of research and exploration and continuous improvement, the process has been integrated through the concrete laser leveling machine. Perfect, the "three super" floors constructed with our company's series of products have reached the domestic or international first-class level.   1. Super flatness: Through the combination of concrete laser leveling machine and professional and precise personnel, the flatness level of (floor) ground can be raised from the current specification of 2 meters by 4mm to 2 meters by 2mm. , (Building) The level of the ground can reach within ±5mm/100m through the laser detection control of two laser sweepers and the imported laser leveling machine.   2. Super strength: Through the professional floor treatment equipment-single-disc and double-disc drive troweling machines several times, the (building) ground forms a real "clear water concrete" surface layer. It is also possible to sprinkle and add color hardening agent during surface construction or to brush liquid concrete sealing and curing agent on the surface of the original slurry "clear water concrete" to improve the surface strength again and truly realize the super strong surface. 3. Ultra-saving: Through the simultaneous construction of the concrete on the (floor) ground, the floor (ground) method is completed at one time, which not only saves the materials, labor, and machinery of the second method, but also avoids the damage caused by the second method. "Empty drums, cracks, peeling, sanding" and other common quality problems; it also reduces the load generated by the materials used in the secondary method between floors, saves the delay in the construction period caused by the secondary method, and greatly saves the construction period. The rental costs of turnover tools and various equipment caused by the elongation have saved a lot of costs and achieved economic benefits created by super-savings. After calculation, the secondary method is based on 6-8cm concrete, and the cost of labor, machinery, and materials required should be more than 40 yuan/m², even if the cost of finished product protection is deducted, the cost savings will be more than 30/m². By solving the concrete surface layer at one time, all the "common quality problems" caused by the second method are completely eliminated. The "three super" floor is flat, clean, dense, high-strength, one-layer overall, with reduced cost, shortened construction period, and absolute durability. It should be said that there is no better method to replace it, whether domestic or foreign.
