The general condition of excavator working bucket teeth directly affects the productivity of the equipment and if their integrity is optimal, it will minimise the mechanical stresses transmitted to the machine, increase productivity and therefore extend service life and reduce maintenance costs.
A common mistake made by owners of excavators, backhoes and other earthmoving equipment is to use the same type of bucket teeth for different tasks without taking into account the nature of the material being moved or its characteristics. This limits the efficiency of the machine in achieving high productivity, increases wear and tear and minimises the life of multiple components.
The structural design of the tooth is related to its digging range. Analysing the type of soil, for example in dense, rocky or frozen terrain, the best choice is a sharp or pointed tooth, as it has a smaller contact surface with the ground and allows the restoration tool to penetrate the material effectively. On the other hand, teeth with relatively wide tips are used for less compact surfaces or for working with materials.
The teeth of buckets are designed differently depending on the degree of wear of the work they will be performing. To choose the right bucket teeth, consider the nature of the soil.
Some machine manufacturers offer their tooth classification system and you should contact your parts supplier to find out their characteristics and uses, but in many cases, in any brand, you can identify any of the following types.
This is the default configuration for excavator buckets and its use is very suitable for loose or loose surfaces with low to medium wear and low to medium impact levels. Its primary use is for trenching.
Suitable for excavators in loose terrain with low wear and versatility. Specifically designed to achieve trenches and finishes. Impact: medium-low.
For excavators working on compact surfaces with high wear and impact, where a high level of digging is required, such as ice, rock. It has the disadvantage of low service life.
They are used for highly compact surfaces with high impact levels, with a higher level of digging compared to the previous examples, and are recommended for execution in low wear environments.
Widely used in excavators requiring low to medium penetration and impact, they have a long service life and an optimal digging range in the above-mentioned soil types, although their use is not recommended for abrasive materials.
