VANSE Machinery warmly reminds you what aspects you should pay attention to when purchasing a car-mounted laser leveling machine

Laser leveling machines are widely used in modern industrial plants, large shopping places, warehouses and other large-area concrete ground construction. Its maintenance can greatly improve the life of the machine and save costs. Laser leveling machine maintenance method/step Fuselage cleaning: When cleaning the surface of the machine, first check whether there is any depression or leakage in the fuel tank, oil pipes, joints, etc., and check whether the fixing screws of the fuel tank bracket are tightened before cleaning. Prevent rust: In the daily maintenance of the laser leveling machine, butter or anti-rust oil should be used to prevent the rust of the exposed parts and mechanical parts, and the gears, sprockets and other parts should be lubricated every half a month.  Leveling: The quality of the leveling and the construction quality also have a necessary relationship. Some buildings have a lot of dust or other sundries, which will cause the leveling machine to level the concrete and become dirty, which will lead to unqualified construction. Therefore, it is usually necessary to Remember to tell Xun Phi to clean the leveling in time. Oil replacement: The engine oil and hydraulic oil in the machine need to be replaced after a period of use. Most people think that it is enough to drain the oil in the oil tank and fill up with new hydraulic oil. But at this time, there will be a lot of old grease trace hydraulic oil in the hydraulic oil pipe. When the equipment is in use, the new oil and the old oil will be mixed together, which will shorten the service life of the new oil. The correct oil change procedure is to drain the hydraulic oil in the hydraulic oil tank first, clean the oil tank and then add new hydraulic oil. Then remove the circuit main pipe, start the engine and run it at a low speed to make the oil pump work, operate each mechanism separately, and use new hydraulic oil to discharge the old oil in the circuit one by one until new oil flows out of the oil return main pipe. Finally, connect the oil return main pipe to the fuel tank, and add new hydraulic oil to the fuel tank to the specified position. Precautions The usual maintenance and maintenance of machinery is important, but it is more important to choose a good machine equipment. VANSE laser leveling machine is your best choice!

    In super-flat floor construction, laser leveling machines are not only efficient paving tools but also crucial for establishing precise elevation. Achieving the super-flatness index of FF/FL requires not only machine automation but also extremely high precision in manual settings. The following are precision setting and operation techniques for laser leveling machines to achieve super-flatness: Avoid interference sources: The transmitter must be installed outside the concrete paving area and away from crane vibrations, passing vehicles, and airflow interference (the support structure needs to be reinforced in windy conditions). Height coverage: Ensure that the transmitter's signal plane covers the entire work area and is not obstructed by on-site columns or equipment. Dual transmitter verification: For extra-large areas, it is recommended to set up two transmitters for mutual verification to ensure that signal attenuation or drift during long-distance transmission is detected in a timely manner. Before the start of each shift, the physical elevation of the top of the formwork must be compared with the signal elevation of the laser transmitter using the same handheld laser receiver rod. Error limit: The error between the measured elevation of the formwork and the laser signal elevation must be controlled within ±1 mm. Technique: Adjust the sensitivity of the hydraulic sensor based on the concrete slump. If the concrete is stiffer, the sensitivity should be appropriately reduced to prevent the leveling head from frequently bouncing due to resistance; if the concrete is thinner, increase the sensitivity to ensure immediate correction of small height differences. Screw Feeder Setting: The lower edge of the screw feeder should be slightly higher than the design elevation (approximately 3-5 mm), using the rear vibrating beam to compact the material to the design position. Material Excess: Always maintain a suitable amount (approximately 2-5 cm) of concrete accumulation in front of the leveling head. Too little material will result in "empty scraping," and too much material will create pushing waves. Operation: Each paving pass should overlap the previously completed pass by 200-300 mm. Technique: Set the hydraulic control on the overlapping side to "manual" and the non-overlapping side to "automatic". This allows the screed to use the completed pavement as a reference, ensuring consistent elevation at the joint and eliminating noticeable "joint ridges". At the end of each paving pass (when the machine retracts its arm), the travel speed should be slightly reduced to prevent the suction created when the screed lifts from pulling up the concrete and causing low spots at the edges. Factors Factors affecting accuracy Troubleshooting Techniques: Wind speed Wind can cause the laser beam to shake. Use windproof supports or add a filtering function to the laser receiver. Concrete slump The consistency (dryness/wetness) of each batch of material varies. Assign a dedicated person to monitor at the discharge point and strictly prohibit spreading material with a slump error exceeding ±20 mm. Tire pressure The amount of tire deflection changes. Check the tire pressure of the leveling machine before starting work each day to ensure symmetry and consistent pressure on both sides. The **first pass with a long-handled straightedge (Highway Straightedge)** after the laser Leveling is completed is crucial: Operation: While the concrete is still plastic, the operator should use an aluminum alloy straightedge of more than 3 meters in length, following the Leveling machine and performing reciprocating leveling perpendicular to the paving direction. Purpose: To eliminate the small marks left by the laser Leveling when changing lines or turning.   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.
