  – Site size – For large-scale concrete construction sites, such as large industrial plants, warehouses, parking lots, etc., it is recommended to choose a ride-on trowel. The ride-on trowel has high working efficiency and can complete large-scale troweling work in a short time. For example, for the floor construction of a logistics warehouse with an area of ​​more than 1,000 square meters, a ride-on trowel can quickly perform rough and fine grinding, effectively saving time and manpower. – For small-area indoor floors or local repair work, a walk-behind or handheld trowel is more suitable. For scenes such as home indoor floor decoration and small store floor repair, the walk-behind trowel is flexible to operate and can easily operate in narrow spaces and corners. – Ground flatness requirements – If the flatness and finish of the ground are extremely high, such as the floor of a high-end shopping mall, the clean workshop of an electronics factory, etc., a double-disc trowel needs to be considered. The double-disc trowel can better ensure the flatness of the ground. Its two trowel discs work at the same time, which can reduce the height difference of the ground and make the ground achieve a mirror-like effect. – For general ground, such as outdoor roads in ordinary houses, simple activity venues, etc., a single-disc trowel can meet basic troweling needs. – Electric trowel – Advantages: The electric trowel has the characteristics of low noise and no pollution, which is suitable for use indoors or in places with high requirements for environmental noise. Moreover, the operation of the electric trowel is relatively simple, and it is convenient to start and stop. You only need to turn on or off the power. – Disadvantages: The working range of the electric trowel is limited by the length of the power cord. If the construction site is large, the socket position may need to be changed frequently. In addition, the power of the electric trowel is relatively weak. When facing thicker or harder concrete, it may be insufficient. – Gasoline trowel – Advantages: The gasoline trowel has strong power, is suitable for various types of concrete, is not limited by the site power supply, and has good maneuverability. It can be freely moved and operated in remote construction sites or large open-air sites without power supply. – Disadvantages: Gasoline trowels are noisy and produce exhaust emissions, which have a certain impact on the environment and the health of operators. In addition, its maintenance cost is relatively high, and parts such as engine oil and spark plugs need to be replaced regularly. – Size of trowel disc – The larger the size of the trowel disc, the larger the coverage area of ​​a single trowel and the higher the work efficiency. Generally, the diameter of the trowel disc of a hand-held trowel is between 600 and 1000 mm, and the diameter of the trowel disc of a ride-on trowel may reach more than 1000 mm. When choosing, determine the appropriate trowel disc size based on the size of the construction site and actual needs. – Speed ​​range – The appropriate speed is one of the key factors to ensure the quality of troweling. Too high a speed may cause the trowel disc to wear too quickly and cause defects such as wavy lines on the ground; too low a speed will affect the troweling efficiency. The speed of a general trowel is between 70 and 150 rpm. The speed range of trowels of different brands and models may vary, and needs to be selected according to specific construction requirements. – Power – The power determines the working capacity of the trowel. For large trowels or when thicker and harder concrete needs to be processed, higher power is required. For example, the power of a ride-on trowel is generally between 5 and 10 horsepower, the power of a walk-behind trowel is usually between 3 and 5 horsepower, and the power of a handheld trowel is relatively low, generally between 1 and 3 horsepower. – The consumable parts of a trowel mainly include trowel blades, bearings, drive belts, etc. When purchasing a trowel, consider whether these consumable parts are in sufficient supply and whether they are easy to purchase. For example, some niche brands of trowels may have consumable parts that are difficult to find, making repair and replacement inconvenient. At the same time, you should also compare the prices of consumable parts of different brands and models of trowel machines, and try to choose a trowel machine with lower consumable parts costs, so as to reduce the cost of later use and maintenance. – Brand reputation: Choosing a trowel machine from a well-known brand can usually guarantee the quality and performance of the product. Well-known brands have stricter standards in product research and development, production processes, quality control, etc., and their products are more reliable. For example, some brands with many years of production experience in the field of construction machinery have had long-term inspections on the market and received good user feedback. – After-sales service: Good after-sales service is an important factor in ensuring the normal use of the trowel machine. After-sales service includes product warranty period, timeliness and professionalism of maintenance services, technical support, etc. When purchasing, you should understand whether the manufacturer provides door-to-door maintenance services, the speed of supply of maintenance parts, and whether there is a professional customer service team to answer questions encountered by users during use.

  The factors that affect the elevation accuracy of the concrete laser leveler are mainly the following: – Laser transmitter: If its installation position is unstable, it is subject to collision, vibration, or displacement or angle changes due to environmental factors such as high temperature and strong wind on the site, the emitted laser reference plane will change, resulting in inaccurate elevation. In addition, the accuracy of the laser transmitter itself is limited, and long service life and aging of internal components will also cause deviations in the emitted laser signal. – Laser receiver: If it fails, such as damage to the sensing element, poor contact of the signal transmission line, etc., it cannot accurately receive and analyze the laser signal, and it is difficult to accurately control the elevation of the leveling head; if the installation position is inaccurate or shifts during construction, the received signal will also deviate from the actual elevation. – Leveling head and transmission system: Structural deformation and wear of the leveling head, such as wear and deformation of the scraper, will affect its leveling effect on concrete; transmission system failures, such as belt slippage and chain loosening, will cause the leveling head to run unstably and fail to accurately adjust the height according to the control system instructions, thereby affecting the elevation accuracy. – Hydraulic system: Poor quality of hydraulic oil, impurities, or leakage and unstable pressure in the hydraulic system will reduce the response speed and control accuracy of the hydraulic system, and fail to adjust the leveling head height in a timely and accurate manner. – Obstacles: Tall buildings, large equipment, and stacked materials at the construction site may block the laser signal, causing the laser receiver to be unable to receive complete and accurate signals, causing the leveling machine to have elevation control deviations in some areas. – Ground foundation conditions: The base surface is uneven and the density is uneven. After the concrete is poured, the concrete surface elevation may be inconsistent due to the settlement difference of the base; soft or raised parts of the base will also affect the normal operation and elevation control of the leveling machine. – Temperature change: Large temperature changes may cause thermal expansion and contraction of equipment components, affecting the mechanical structure of the equipment and the accuracy of the laser system; at the same time, temperature affects the setting speed and fluidity of concrete. If the construction parameters are not adjusted in time, it may also cause deviations in elevation control. – Wind impact: Construction in a windy environment may cause the laser transmitter to shake, affecting the stability of the laser signal; strong winds may also disturb the concrete surface, causing the newly leveled concrete surface to fluctuate, affecting the accuracy of the elevation. – Concrete performance: The slump of concrete is inconsistent, which will lead to different fluidity. During the leveling process, the thinner concrete and the drier concrete have different forces on the leveling machine, which will affect the height control of the leveling head and cause elevation deviation; in addition, the unstable setting time of concrete will also affect the construction progress and leveling effect. – Construction operation: Operators are not familiar with equipment operation, such as uneven walking speed, improper lifting and lowering of the leveling head, etc., which will affect the leveling effect and elevation accuracy of the concrete; during the concrete pouring process, uneven distribution, local concrete accumulation or shortage will also cause elevation errors in the leveling machine during the leveling process. – High-level verification: Inaccurate setting of the benchmark leveling point before construction, or damage to the benchmark leveling point during construction, and operating errors of the handheld receiver during the high-level verification, etc., will lead to inaccurate elevation benchmarks introduced into the leveling machine.  

  Concrete laser leveling machines have been developed for many years and have also been "flourishing" in the construction industry. However, it is difficult for us to continue to expand and strengthen the company by relying solely on traditional sales models and sales ideas, so the transformation of enterprises or sales models is unstoppable. So how should we seize the opportunity in this wave of transformation? At present, after years of development, the laser leveling machine industry has become increasingly mature. Now the industry is also undergoing major changes. For example, with the use of the Internet and the development of e-commerce, the external environment of laser leveling machine companies is undergoing major changes, which profoundly affects the business behavior of all laser leveling machine companies. Mobile Internet has completely broken the information barrier, allowing users to obtain information anytime and anywhere. The information asymmetry between sellers and buyers gradually disappears. Therefore, the business that used to make money by information asymmetry will face death. At the same time, users are no longer easily fooled, and the saying that "buyers are not as smart as sellers" is being rewritten. "Whoever masters big data will master the big future." Nowadays, many laser leveling machine companies have seen the opportunities brought by "big data". For example, with the support of big data, in addition to a specific laser leveling machine brand being able to implement product improvements, service enhancements, and order follow-up based on statistical data, it can also be associated with similar brands to achieve interactive marketing. In the past, the interactive marketing of the laser leveling machine industry relied on alliances, which were all spontaneously organized by enterprises and may not be in line with consumer needs. Now, through the intuitive presentation of big data, it can be found that users have a correlation with brand choices. Brands with a high correlation ratio can actively unite to provide users with preferential marketing or service interactions, thereby truly meeting consumer needs. In terms of brand building, the e-commerce field is undoubtedly a blue ocean. Indeed, in today's era, mobile Internet has penetrated everywhere, and the business opportunities hidden in this world are extremely huge. If laser leveling machine companies seize the opportunity in these aspects and actively adjust their strategies, then they will definitely make a big splash in the future development. In the next five years, the laser leveling machine industry will be reshuffled. Whether it is a listed company, a state-owned enterprise, or a private enterprise, they will face a very severe situation in the next five years. Especially in the next three years, the laser leveling machine industry will be dominated by big fish eating small fish and fast fish eating slow fish, which will be the norm of the industry, because the market space is so large, which is also the inevitable result of market rules. Non-listed companies may be basically eliminated or integrated. How to avoid being at a disadvantage in the competition? How to choose the direction of transformation? No one can predict the future. To grasp the market and predict the future, it is necessary to analyze a large amount of data. Moreover, the extremely popular e-commerce in recent years has provided great convenience for data collection. It is urgent for laser leveling machine companies to move towards "big data". Although the development of the entire industry cannot be separated from leading enterprises, at the current stage, the strength of those small and medium-sized laser leveling machine manufacturers with vision, characteristics and strengths is also indispensable, especially for the application industry that is about to usher in great development. It is a time when hundreds of boats are competing for the current and thousands of sails are competing. The prospects of small and medium-sized laser leveling machine companies can still be grasped.
