2024 New Type 1.3ton Crawler Excavator

Since the 1980s and 1990s, small construction machinery has exerted great advantages in municipal engineering, transportation and other construction projects and has developed rapidly. Small excavators have made great contributions to saving manpower and material resources in these projects, meeting various urban operation requirements, maximizing their production capabilities in the narrow working space of the city, and gradually becoming a representative tool in urban construction. construction machinery. The development of small excavators mainly depends on the development of urban construction. Due to the large number of urban reconstruction and construction projects, it requires short construction time, small impact of construction machinery on the surrounding environment, safety, low pollution, small turning radius, easy transportation, and features Coordinated looks with city views and more.

It is generally composed of power device, transmission device, walking device and working device. Principle: Use a bucket to excavate materials above or below the bearing surface, and load them into transportation vehicles or earthmoving machinery that are unloaded to the stockyard. A self-propelled mining machine that uses a bucket to scoop strips or mineral products from the working face and transport them to a dumping site for unloading. History: The first manual excavator has a history of more than 130 years. During this period, it has experienced the development from steam-driven bucket rotary excavators to electric-driven and internal combustion engine-driven rotary excavators, and fully automatic hydraulic excavators using electromechanical and hydraulic integration technology. step-by-step development process.

Due to the application of hydraulic technology, there were mounted excavators equipped with hydraulic backhoes on tractors in the 1940s. In the early and mid-1950s, towed full-rotation hydraulic excavators and crawler-type fully hydraulic excavators were developed. . The initial trial production of hydraulic excavators used the hydraulic technology of aircraft and machine tools. They lacked hydraulic components suitable for various working conditions of the excavator. The manufacturing quality was not stable enough and the supporting parts were not complete. Since the 1960s, hydraulic excavators have entered a stage of promotion and vigorous development. Excavator manufacturers and varieties in various countries have increased rapidly, and output has surged. From 1968 to 1970, the output of hydraulic excavators accounted for 83% of the total excavator output, which is close to 100%.

Developmental design: Apply mature design experience or feasible new technologies to design new small excavators, mainly including functional design and mechanism design.

Upgradeable design: Based on usage experience and technological development, existing small excavator designs are updated and upgraded to improve performance, reduce manufacturing costs or reduce operating expenses.

Generative design: In order to adapt to new needs, some modifications, additions or deletions are made to existing small excavators, thereby developing derivative products that are different from the standard type.

Serialized design: Taking a small excavator as the parent model, we design a series of products with the same function and similar appearance, but with different power, tonnage and size.
