ATTACHMENT GUIDE

TRACK SHOES SELECTION

Select the appropriate track shoe to match the operating conditions.
Selection
Check the category from the uses in the table below, then select the shoes from the table below that.
Category of use B and C are the wide shoe, so there are limits on the use. Check the precautions for use,
examine the conditions of use thoroughly, and use the optimum shoes for the situation.
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, this may cause problems such as bending of the shoe,
cracking of the link, damage of the pin, and looseness of the shoe bolts.
