Excavator shovel - shaped like dustpan, a tooth floor and bucket teeth.During the operation, the barrel is thrown onto the excavation face.Bucket teeth by self - weight cut into soil.Then, dig the bucket by pulling it over the fuse cable.After full excavation, lift the bucket with a sling.The dump bucket adjusts the dump point through the rotary table.It can be dug below the retaining surface, but the excavation accuracy is poor.

Excavators are classified into standard type, reinforced type and mine type according to the properties of structural materials.

The standard bucket material is Q345B, which is made of domestic high-quality high-strength structural steel.The characteristics of standard bucket are: large bucket area, large pile surface, high filling coefficient, saving operation time, high efficiency.Suitable for general clay excavation and sand, soil, gravel loading.

On the basis of standard bucket, the reinforcing bucket is made of high strength wear-resistant steel material, which is used for high stress and wearing parts.The tooth bottom plate and the side edge of the wearing parts are made of high-quality high-strength wear-resistant steel NM360 with thicker plate and longer service life.It inherits all the advantages of the standard bucket and greatly improves its strength and wear resistance.Suitable conditions are heavy duty operations such as digging hard soil, gravel and gravel loading.
