SELECTION OF TRACK SHOE
Suitable track shoes should be selected according to operating conditions.
Method of selecting shoes
Confirm the category from the list of applications in table 2, then use table 1 to select the shoe.
Wide shoes(Categories B and C) have limitations on applications. Before using wide shoes, check
the precautions, then investigate and study the operating conditions to confirm if these shoes are
suitable.
Select the narrowest shoe possible to meet the required flotation and ground pressure. Application
of wider shoes than recommendations will cause unexpected problem such as bending of shoes,
crack of link, breakage of pin, loosening of shoe bolts and the other various problems.
