The maintenance and management of the excavator in the western desert west, especially the Taklama -Ganan desert areas, are becoming a*area for my country's petroleum development and geological exploration and development. Infrastructure construction such as roads and bridges is rapidly developing. The climate characteristics of the region are that the wind and sand are constantly; the temperature difference between day and night during late autumn to early spring is above 20 ° C; the surface temperature of the surface in summer is as high as 70 ° C. The excavator must have practical use and management measures in such a climate environment. 1. Daily use, maintenance and maintenance and maintenance of the western desert areas, the wind and sand are constantly, and there are a large amount of dust in the air. If the dust enters the engine cylinder, it will accelerate the wear of the piston and the cylinder and affect the life of the engine. If the dust enters the hydraulic system or t

The application of anti -shovel excavators in highway construction is one of the main construction machinery in the earth and stone engineering. composition. Among them, the work device is replaced by a dozen types according to the work requirements, so it is widely used in various projects such as highways, railways, buildings, mines, water conservancy, national defense. According to statistics, about 60%of the earth and stone projects in various projects are completed by the excavation machine. At present, anti -shovel excavators are mainly used in highway engineering, and the application of anti -shovel excavators in highway construction is introduced below. 1. The basic operation of the anti -shovel excavator machine. The anti -shovel excavator is mainly used to excavate the earth and stones in the road construction.

The Sany excavator stationed in the southern disaster front line. Recently, the south has continuously heavy rainfall, which has caused traffic obstacles in many cities and regions and serious threats to residents' lives. According to statistics from relevant departments, the strongest precipitation since the summer of this year is more than 5%compared to the 1998 special flood disasters. This makes people can't help sucking cold.

The "Great Flood in 1998" once laid an indelible mark in the hearts of the Chinese people. The flood took away people's homes and life. It was a sad memory that people did not want to mention. So this year, what will this great rainfall in the south bring us? From an objective perspective, in the past eighteen years, my country has made huge efforts in the construction of returning to the lake and reservoir dam. From the perspective of hardware configuration, the level of science and technology has also been compared to 1998

The construction of the excavator plateau should pay attention to what to pay attention to in the western region. Driven the strategy of all the way, more and more projects are settled to the Western Gahai Duan area. More and more engineering machinery gathered here. At this time, everyone is everyone More or more will find that the excavator equipment also has a plateau reaction to high altitude areas. Analysis of the reason, and then apply the correct response solution, so that the excavator machine can be flat in the plateau area. First of all, let's take a look at several problems that are prone to construction in the plateau area? I. Difficulty of excavators in the plateau area 1. The working temperature of the battery is from 20 ° C to 40 ° C. As the environmental temperature decreases, the output capacity of the battery has decreased accordingly. When the temperature is lower than 30 ° C, the battery capacity is reduced by 1%to 1.5%per 1 ° C
