Everyone knows that the excavator is the main machine in the construction of the project. It has the advantages of versatility, excellent functions, large excavating power of the bucket, and convenient operation. It also plays an increasingly important role in increasing the construction speed of the project and reducing the labor intensity of workers. The more important role.
When the mini excavator is not careful when it is operating, a safety accident may occur, not only the safety of the driver but also the life of others.
1. When using the mini excavator, no one is allowed to go up and down the excavator and transfer items. It is not allowed to maintain while working; do not adjust the engine (speed governor), hydraulic system, and electronic control system at will; pay attention to selection and creation of reasonable Excavation is strictly prohibited.
2. When unloading the mini excavator, it should be done after the dump truck is stopped; when unloading, without colliding with any part of the dump truck, the height of the bucket should be lowered during the day; the bucket is prohibited from passing over the dump truck cab. The most important points to be noticed during the training of Yantai excavator.
3. It is forbidden to use a bucket to crush solid objects; if it encounters large stones or hard objects, it should be cleared first and then continue to work; it is forbidden to excavate rocks that have been blasted and above grade 5.
4. It is forbidden to arrange the excavator to work in the upper and lower excavation sections at the same time; when the excavator moves in the working surface, the ground should be leveled first, and the obstacles in the passage should be cleared.
5. It is forbidden to lift the mini excavator with the bucket cylinder fully extended. When the bucket does not leave the ground, the excavator cannot move sideways or swing.
6. It is forbidden to use the excavating manipulator to drag other objects laterally; hydraulic excavators cannot use the impact method to excavate.
So what can we do to reduce the problems of the machine and extend the service life of the excavator bucket?
1. Fuel management
According to the ambient temperature, select different grades of qualified fuel. Otherwise, the inferior fuel with high sulfur content will cause damage to the engine; the diesel should not be mixed with impurities, dirt and water, otherwise the fuel pump will wear prematurely; the excavator driver is required to fill the fuel tank with fuel after the daily work, avoiding the fuel tank Water droplets are generated on the inner wall; open the drain valve at the bottom of the fuel tank to discharge water before daily operations.
2. Management of engine oil, hydraulic oil and gear oil
Do not mix oils of different brands and grades; ensure that the oil is clean and avoid mixing of debris (water, dust, particles, etc.); use oils of different labels according to the ambient temperature and use, and use high-viscosity motor oils if the ambient temperature is high When the ambient temperature is low, use oil with a relatively low viscosity; the viscosity of the gear oil is larger to comply with the larger transmission load; the viscosity of the hydraulic oil is smaller, the purpose is to increase the resistance of the liquid activity.
3. Management of smooth grease
Smooth grease can reduce the wear of sports appearance. When storing smooth grease, it should be noted that dust, sand, water and other impurities should not be mixed; when filling, the old oil should be squeezed out and wiped clean to avoid sand adhesion.
4. Maintenance of filter element
The filter element plays the role of filtering impurities in the oil or gas path, preventing impurities from intruding into parts and causing failure; use a filter element suitable for the machine; various filter elements should be replaced regularly in accordance with the requirements of the (Operation and Maintenance Manual). Check whether there is metal attached to the old filter element. If metal particles are found, they should be cleaned in time.
In addition, when the excavator fails to work, please do not continue to use it to avoid unnecessary damage.
