There are three common road construction machines in real life. Let's take a look. Loader Loader Definition: Loader is a kind of earthwork construction machinery widely used in highway, railway, construction, hydropower, port, mine and other construction projects. It is mainly used for shoveling and loading soil, sand and stone, lime, coal and other loose materials, but also for ore, hard soil and other light shoveling and digging operations. Loading, lifting and other materials can be carried out by changing different auxiliary working devices. Motor Grader A grader is an earthmoving machine that uses a scraper to level the ground. The scraper is mounted between the front and rear axles of the machine and can be lifted, tilted, swiveled and extended. The movement is flexible and accurate, the operation is convenient, and the leveling site has high precision. It is suitable for constructing roadbed and road surface, building slope, excavating side ditch, stirring the groun

Let's take a look at the safety precautions for the  bulldozer with reliable quality . 1. The operator must be certified to work, and non-professional drivers are strictly prohibited. Do not leave the post without authorization, and do not operate machinery that does not conform to the operating permit. It is strictly forbidden to hand over the mechanical equipment to the personnel who do not have the operating license of the machine. Drinking operations are strictly prohibited. 2. The operator must strictly follow the instructions in the manual to strictly observe the inspection system before work and the inspection and maintenance system after work observation and work. 3. When the mechanical equipment is parked at the construction site, the safe parking place should be selected, the cab (operating room) door should be locked, and the parking brake should be pulled. When parking on a ramp, you should use triangular wood or stone to hold the wheel.  4. When multiple machi

In actual production, there is some construction machinery such as  bulldozer with reliable quality  that needs long-term storage. So how should the construction machinery be stored for a long time, what problems should be paid attention to? 1. Park in a dry room. If you have to stop outside, you should choose a flat floor and put wood. Cover it with a cover after parking. 2. Before long-term storage, the machinery must be repaired, repaired the damaged and thoroughly cleaned to maintain good technical condition. 3. The arrangement at the parking spaces shall ensure that the entry and exit of any machinery are not affected by other machinery. 4. The mechanical fuel control lever should be placed in the idle position, and each joystick should be placed in the neutral position. 5. Storage of the engine. Release the cooling water from the engine. Replace the engine oil. The fuel tank is topped up with diesel to avoid rusting of the fuel tank. During the shutdown period, the eng

The  motor grader  is commonly used to level the ground and flat. Graders come in different sizes and shapes, but they all have the same specifications and configurations. 1. Motor graders are used to dividing uneven, inefficient surfaces such as roads, lawns, and landscapes. Scarring is the process of removing the entire soil or layer of land and then laying a new layer. 2. Motor graders are used for trenching, shallow holes and trenching. 3. They are also used to lay pipes and pipes and to make channels for bank channels. 4. Motor graders helping create smooth, fine roads or ground. 5. They are also used to move ungrounded soil and debris or original building materials from one location to another with the help of front wide blades. 6. Some graders are also used to mix two or more materials used in construction projects. 7. Some graders with special attachments can be used for individual tasks, such as underground mining. 8. Typically, these graders are also used to

There are distinct kinds of dozers that change based on their usage. Some bulldozers are modified by substituting the blade with big hydraulic arms and metal buckets. These modifications help in raising the utilities of dozers. Here are some of the different types of dozers: Crawler Dozer This is a kind of bulldozer that resembles a tractor. It's used to push sand and other heavy materials from one spot to another. They are available in assorted sizes. The large crawlers have a ripper installed in the machine's back end and therefore are capable of beating any hard surface. This is a type of dozer which is most suitable in irregular fields because of the abrasive plate. Wheeled Dozer Wheeled dozers are larger than the crawler ones. These are the varieties of dozers that are used in the majority of the building plans like water parks and stadiums. Their high efficiency and performance make them suitable for this kind of work. The wheeled dozers come with big and heavy t

Let's take a look at the parts where crawler dozers often wear out. First, the wear of the bulldozer crawler. In a running gear of a dry track (relative to a lubricated track and a sealed track), the track is not lubricated, causing wear due to relative movement between the track pin and the pin sleeve during operation. Wear between the pin and pin bushings in the track is unavoidable and normal, but this wear will cause the pitch of the track to elongate and the track to be too large. This wear continues, and the track will move sideways, causing wear on the guide wheels, the roller, the carrier roller, the drive gear, etc. and also the wear of the track pin and sleeve. Second, the wear of the bulldozer drive wheel. The wear of the drive wheel teeth often occurs at the root of the teeth, the front and rear sides, the left and right sides, and the top of the gear teeth. When the   bulldozer with reliable quality  travels forward and the gears hold up the track pin bushing,
