How to maintain a large pavement concrete trowel?

In the construction process of concrete laser leveling machine, it can timely discover and repair all kinds of faults and defects of the machine, which is the basic guarantee of efficient operation and prolong service life of the machine. Generally speaking, doing a good job in daily point inspection is of great significance to improve the production efficiency of concrete laser leveling machine and reduce the cost of use and maintenance. The following after-sales department of Wanshi Machinery Technology Co., Ltd. will explain in detail the necessary measures to reasonably extend the service life of machinery, so as to ensure the normal service life of construction machinery and give full play to its due benefits: 1. After the work is completed, please use the arm lift button to manually lift the nose of the machine and then push out the construction site. Do not push the machine when the vibration leveling part is in contact with the ground, so as not to cause damage to the vibration plate. 2. After the completion of construction, it is necessary to wash the machine with high pressure water gun in time (it is strictly forbidden to wash the water gun directly at the mesh part of the fuselage, so as to avoid water entering the inside of the fuselage and causing circuit short circuit). 3. The place where the machine is placed must be kept dry, and sundries and inflammable and explosive materials shall not be piled up around it. 4. The battery of the machine also needs to be paid attention to. If it is not used together for a long time, make sure to remove all batteries from the host and receiver and store them properly. The transmitter comes with a rechargeable battery that lasts eight hours. 5. During the use of the machine, please try to charge the battery after it is fully used, and try to ensure that it is fully charged for 8 hours at a time. The first charging time is recommended to be 12 hours, and the next charging time is 8 hours. In order to avoid damage to the battery and the transmitter, please unplug the power plug in time. 6. If the laser signal is lost during the construction process and the machine needs to be restarted, the interval time should be more than ten seconds. 7, if the machine is not used for a long time on a stable ground, each bearing part should be added grease once a week, each chain should also be often added lubricating oil, in order to maintain good lubrication, at the same time should pay attention to avoid sand and other sundry get to the chain, in case of premature chain damage. Generally, a month or the end of each construction period, the machine should be comprehensively inspected and maintained once. Attention should always be paid to the tightness of the triangle belt and chain, which should be adjusted in time when it is too loose, and the fastening bolts should also be often spread to prevent loosening.

    Yes, they absolutely can, but with a few technical "fine print" warnings. While these machines are designed for dry-shake hardeners (which are essentially a pre-mixed blend of cement, sand, and additives), you can certainly use them to distribute specific components like pigments or anti-slip agents-provided you respect the machine's mechanical limits. Here is how concrete topping spreaders handle various additives and the adjustments you need to make. Most "color" in industrial floors isn't pure pigment; it's a Color Hardener (pigment + cement + fine aggregate). The Spreader's Role: It is the only way to get a perfectly uniform color. Hand-tossing color usually results in "leopard spots." The Risk: Pure, raw pigment is often too fine (like flour). If you put pure pigment in a spreader, it may "bridge" (clump together) in the hopper and refuse to fall through the rotor. The Fix: Ensure the pigment is part of a engineered dry-shake mix. If you must use pure pigment, it should be blended with a carrier (like fine sand) to give it enough "weight" to flow through the machine. For loading docks or wet processing areas, you might spread Silicon Carbide or Aluminum Oxide. Handling: These materials are much denser and "grittier" than standard hardeners. Machine Wear: These are essentially sandpaper for your equipment. If you are running high volumes of anti-slip agents, you will notice accelerated wear on the rubber seals and the discharge rotor. Distribution: Because these grains are heavy, they drop very fast. You usually need to tighten the discharge gap on the spreader to prevent "dumping" too much material in one spot. Additive Type Material Examples Spreader Compatibility Key Challenge Metallic Aggregates Iron filings, steel grit Excellent High weight; requires heavy-duty motors. Anti-Slip Silicon Carbide, Quartz Good Highly abrasive; wears down internal parts. Reflective Glass beads, "Sparkle" grain Moderate Very fragile; can "crush" in the rotor. Pure Pigment Iron oxide powders Difficult Clumping and "dusting" (blown away by wind). If you are switching from a high-visibility color (like "Safety Red") to a standard grey hardener, a simple shake-out isn't enough. The Danger: Residual pigment trapped in the rotor corners will "bleed" into the next project for the first 100 feet. The Fix: Use a shop-vac and a stiff brush to clean the internal discharge vanes. Some operators run a "sacrificial" 25 kg bag of plain sand through the machine to scrub the pigment out before starting the next color. Additives like pure pigments are extremely hygroscopic (they suck moisture out of the air). If you leave specialized additives in the hopper during a lunch break or a rain delay, they can "cake" onto the rotor. The Rule: Only load what you are about to spread immediately. Not all additives weigh the same. 1 Liter of Steel Aggregate weighs much more than 1 Liter of Glass Beads. The Test: Before starting the actual floor, run a "10-foot test" on a piece of plastic or a dry section of the slab. Weigh the material dropped to ensure your kg/㎡ (or lb/ft^2) matches the project spec. Integrated Blends: Yes, flawlessly. This is what they are built for. Raw Abrasives: Yes, but expect higher maintenance on the machine. Fine Powders: No, unless blended with a carrier to improve flow.   Pro Tip: When spreading reflective beads or very fine anti-slip grains, lower the discharge height of the spreader head as much as possible. Even a light breeze in a warehouse can blow 20% of your expensive additives away before they even hit the wet concrete.   Would you like me to find the recommended "Drop Rates" (kg/㎡) for standard VS heavy-duty industrial wear layers?  Contact us NOW   Note: The parameters provided in this document are for reference only and are not mandatory.
