What does the fault code C0 13 of Shenzhen-Hong Kong excavator mean?

The front pound pressure sensor is open.

Excavator [1], also known as digging machine, is an earth-moving machine that uses a bucket to dig out materials above or below the bearing surface, load them into transport vehicles or unload them into the yard.

The materials excavated by excavators are mainly soil, coal, sediments and pre-loosened soil and rocks. Judging from the development of construction machinery in recent years, excavators have developed relatively rapidly, and excavators have become one of the most important construction machinery in engineering construction. The three most important parameters of excavator are working weight (mass), engine power and bucket capacity.

At first, the excavator was manual, and it has been more than 30 years since its invention to 20 13. During this period, it has experienced a gradual development process from steam-driven bucket rotary excavator to electric-driven rotary excavator and internal combustion engine-driven rotary excavator, and then to fully automatic hydraulic excavator with electromechanical and hydraulic integration technology. The first hydraulic excavator was successfully invented by Boquelin Factory. Due to the application of hydraulic technology, in the 1940s, there appeared a hanging excavator equipped with a hydraulic backhoe on tractors. 195 1 year, the first full hydraulic backhoe excavator was launched by Poquelin factory, which opened up a new space in the field of excavator technology development. In the middle and early 1950s, traction hydraulic excavator and crawler hydraulic excavator were successfully developed. The original trial-produced hydraulic excavator used the hydraulic technology of aircraft and machine tools, and lacked hydraulic components suitable for various working conditions of the excavator, so the manufacturing quality was not stable enough and the supporting parts were not complete. Since the 1960s, hydraulic excavators have entered the stage of popularization and vigorous development, and the manufacturers and varieties of excavators in various countries have increased rapidly, and the output has soared. During the period of 1968- 1970, the output of hydraulic excavators has accounted for 83% of the total output of excavators, which is close to 100%[2]? .

The first generation of excavators: the emergence of electric motors and internal combustion engines made excavators have advanced and applicable electric devices, so various excavator products were born one after another. 1899, the first electric excavator appeared. After World War I, diesel engines were also used in excavators. This kind of mechanical excavator driven by diesel engine (or motor) is the first generation excavator.

The second generation excavator: With the wide application of hydraulic technology, excavators have more scientific and applicable transmission devices, and hydraulic transmission instead of mechanical transmission is a great leap in excavator technology. The first hydraulic excavator in Germany was born in 1950. Hydromechanical transmission is the second generation excavator.

The third generation excavator: The wide application of electronic technology, especially computer technology, makes the excavator have an automatic control system, and also makes the excavator develop in the direction of high performance, automation and intelligence. The germination of mechatronics took place around 1965, and the electromechanical integration technology was adopted on the hydraulic excavator mass-produced around 1985, and the main purpose at that time was to save energy. Electric excavator is the symbol of the third generation excavator.

Excavator manufacturers can be roughly divided into four categories. More than 70% of domestic excavators are occupied by foreign brands, and domestic brands mainly dig small and medium, but the share of domestic excavators is gradually increasing, with a year-on-year increase of 3.6% in 20 12.
