Any road construction machinery will inevitably be affected by external environmental factors, and this is no exception for laser levelers, especially in the hot and rainy summer. Once the laser leveler is exposed to too much rain, it is very likely to cause a series of problems such as rust on the leveler body and damage to parts. In order to avoid unnecessary maintenance costs and extend the service life of the leveler, it is particularly necessary to do a good job of laser leveling maintenance in the rainy season. Below, our company will combine its own years of work experience to make several suggestions on how to do a good job of protecting the leveler in the rainy season. First, before parking the laser leveler, you should use your naked eyes to observe and judge whether the surrounding geographical environment is safe, stay away from rivers or hillsides that may cause landslides. Under a big tree is not a good parking place. It is easy to be struck by lightning in thunderstorms, and if a big tree is blown down on the laser leveler in windy weather, it will also cause great losses. Choose a place with a solid road surface to park. It is good to be able to park on cement or asphalt, but our leveling machine usually rarely has cement roads. Most of them are operated in the field. In this case, you should choose to park on a stable ground for a long time, and try to avoid parking on the fill ground. Second, if necessary, you need to install anti-skid chains on the laser leveler to increase the safety factor. The installation of anti-skid chains should be carried out in advance. Do not start installing them in an emergency environment. Such hasty installation is unsafe and troublesome. If it is a special case, safety warning signs must be placed before and after the laser leveler. Do not install anti-skid chains when the tire pressure is insufficient. Also pay attention to the different sizes of anti-skid chains. Choose anti-skid chains that match the size of the wheel hub and wheel width. After installing the anti-skid chain, pay attention to the driving speed of the roller should not be too fast, and also pay attention to avoid sudden acceleration or deceleration to cause damage to the anti-skid chain. Third, if conditions permit, you can park in the garage, and try to avoid parking in an overly humid environment and choose indoor storage. The rust prevention of laser leveling machines is very important. If the machine is parked for a long time, it should be started and driven once a month to charge the battery. After the machine is stored for a long time, the grease on the piston rod should be wiped dry and all parts should be filled with grease. When the machine is parked, the working device should be kept dry and clean, and water should not be put in to avoid rust and make the machine inconvenient to operate. In fact, in addition to the above aspects, there are many details that need to be paid attention to during the construction of the laser leveling machine in the rainy season. This site will continue to pay attention to, organize and share related content. Interested users can directly visit the official website of this site to inquire and obtain it. I believe it will be helpful for your future use.

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.
