Precaution for track shoe selection
• Since the classifications by use “B” and “C” are for wide shoe, their use is limited.
Check the precautions for use and the using condition, and then use a suitable shoe.
• When selecting the shoe width, choose the narrowest shoes possible to bring the machine within the range
where there is no problem regarding the machine flotation and ground contact pressure.
If wider shoes than necessary are used, the load on the shoe will increase. It may cause problems such as
bending of the shoe, cracking of the link, damage of the pin, and looseness of the shoe bolts.
BUCKET TEETH SELECTION
Depending on the working conditions, there is a danger that an adapter and tooth may be lost. Select either one
from the vertical pin type of tooth or horizontal pin type of tooth that is 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.
METHOD FOR SELECTING TEETH
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.
