Daily operation, maintenance and maintenance of truck cranes

The rotation rig is a construction machinery that is suitable for hole -forming operations in the basic engineering of the construction. It is widely used in infrastructure construction projects such as municipal construction, highway bridges, high -rise buildings and other places, and cooperate with different drillings, which are suitable for hole -forming operations of dry (short spiral), wet type (rotation) and rock formation (rock diamond). The rotary rig drilling machine is mainly suitable for the construction of soil layers such as sand, viscous soil, and powder soil. It is widely used in various foundation infrastructure such as irrigation piles, continuous walls, and basic reinforcement. The rated power of the rotor rig is generally 125-450kW, the power output torque is 120-400kn · m, the maximum hole diameter can reach 1.5-4m, and the maximum hole depth is 60-90m. Essence The rotary rotor drilling machine has the

How many machines are the five major repair techniques for the excavator hand -made engine. Have the engine faulty problems when driving the excavator? What will be dealt with when the engine is abnormal? Let me talk about the common manifestations and judgment methods of engine failure. I. Insufficient motor power of the excavator, an abnormal noise, an analysis of the failure of the exhaust pipe with black smoke: This phenomenon is due to the late ignition, the pressure of the machine combustion chamber is insufficient, and the engine power drops suddenly. As a result, a loud noise. And because the burning gas is mixed with it to produce black smoke. Solution: If you find a problem, you should contact the repair shop in time for repair. Second, when the excavator engine oil appears, a large amount of failure is analyzed

High frequency analysis of hydraulic excavators has a high frequency of failure. Nowadays, the technology of excavators has been significantly improved. With the advancement of science and technology, modern excavators basically adopt the control mode of machine, electricity, and liquid. Therefore, in the process of actual operation, if the excavator fails, we usually check the matching problems of the engine, hydraulic pump and external load. In the process of excavators, most of the problems appear on the matching of external loads. If they do not get a good match in this area, the engine speed will slow down, the operating speed is slow, or even the weakness. Below, let's take a look at the performance and exclusion method of these fault problems. Slow the engine speed. If the output power of the engine is far lower than the rated power, you should check whether the fuel filter element has occurred

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
