The 2-ton mini excavator uses the national standard steel Q235B, and the steel quality has passed the test, preventing the cracking and distortion of the inferior steel. At the same time, the main stress components, such as the big and small arms, buckets, swings, chassis and other parts are individually thickened and widened to improve the force strength and ensure stable 。performance.

Body structure of 2-ton mini excavator


1.The frame assembly of the 2-ton mini excavator refers to its overall welding parts. The excavator adopts an X-type structure. The advantage of this structure is that it has a relatively high bearing capacity. The national standard steel Q235B is selected to prevent the cracking, distortion and other phenomena of inferior steel. At the same time, the main force-bearing parts, such as the big and small arms, buckets, swings, chassis and other parts, are individually thickened and widened to improve the force strength and ensure stable performance.


2.Boom, arm, bucket and chassis support, uses bending process, cooperates with the box-type design, which is matched with full welding splicing to greatly improve the structural strength of the whole machine, without cracking or deformation. More powerful, more stable transfer, and durable vehicle structural parts. The strength and service life of the whole vehicle are obviously better than the hollow and veneer design of ordinary products.


3.The bucket teeth of the bucket are made of cast steel, which is sturdy and wear-resistant, and is powerful for digging. The bucket body is bent and fully welded, and the wear-resistant layer is added to the back, which greatly improves the life of the bucket.

2-ton mini excavator integrated boom

The boom is the core component of the backhoe, which can be divided into two types: integrated type and combined type.

The advantages of the integrated boom are simple structure, light weight and high rigidity. The disadvantage is that there are few working devices to be replaced, and the versatility is poor, and it is mostly used on 2-ton mini excavators with similar long-term operating conditions. The integrated boom can be divided into two types: straight boom and curved boom. Among them, the straight boom has a simple structure and light weight, which is easy to manufacture. It is mainly used for a suspended 2-ton mini excavator, but it cannot make the excavator obtain a large excavation depth and is not suitable for general-purpose excavators. Curved boom is the most widely used structural form, compared with the straight boom, can make the excavator have a larger digging depth, but reduce the unloading height, which meets the operation requirements.

Combined boom for 2-ton mini excavator


The combined boom is connected by auxiliary rods (or hydraulic cylinders) or bolts. The angle between the upper and lower booms can be adjusted by auxiliary rods or hydraulic cylinders. Although the structure and operation are complicated, the angle between the upper and lower booms can be greatly adjusted at any time during the excavator operation, thereby increasing the 2-ton mini excavator working performance, especially when excavating narrow and deep foundation pits with a bucket, it is easy to obtain a vertical excavation trajectory of a large distance, which improves the excavation quality and productivity. The advantage of the combined boom is that the working size and digging capacity of the excavator can be adjusted at will according to the working conditions, and the adjustment time is short. In addition, there are many interchangeable working devices, which can meet the needs of various operations, and are convenient for loading and transportation.

2-ton mini excavator bucket.

1. The longitudinal section of the bucket should adapt to the movement law of various materials in the bucket during the excavation process, which is good to the flow of materials, minimizes the resistance of soil loading, and is conducive to filling the bucket.

2. The 2-ton mini excavator is equipped with bucket teeth to increase the digging force of the bucket. The bucket teeth have a small unit cutting resistance, which is convenient for cutting into and breaking the soil. The bucket teeth are wear-resistant and easy to replace.

3. In order to make the material of the bucket not easily fall out, the ratio of bucket width to diameter should be larger than 4:1.

4. The material is easy to unload, shorten the unloading time, and improve the volumetric efficiency of the bucket.
