BUCKET TEETH SELECTION

Depending on the working conditions, there is danger that an adapter and teeth may break, so select from the
vertical pin and horizontal pin teeth to give teeth that are suitable for the purpose.
While the standard teeth of both vertical and horizontal pin types may be used widely, the following kinds of teeth
are recommended depending on the working conditions.
Teeth Selection
Vertical Pin Type Tooth
General digging: Digging and loading normal soil, such as sand, gravel, clay, etc.
Light-duty digging: digging and loading dry and loose sandy soil, or muddy soil.
Loading: loading of dry and loose earth.
Horizontal Pin Type Tooth
Heavy-duty digging: Digging and hammering work on hard soil, soil with rocks, scraping or other heavy-duty work
The heavy-duty bucket is of a horizontal pin type and as such, use it for heavy duty-digging.
Long-life Tooth
Jobsites where long wear life is demanded, such as when loading hard rocks.
Jobsites where no penetration is needed, such as when working with crushed rocks after blasting or ripping.
Jobsites where heavy-duty operations are carried out, such as hitting or pulling up rocks with the tips of the teeth.
Self-sharpening Tooth
Jobsites demanding penetration such as digging and loading sandy or clayey soil.
