SELECTION OF TRACK SHOES
Select suitable track shoes to match the operating conditions.
METHOD OF SELECTING SHOES 6
Confirm the category from the list of uses in Table 1, then use Table 2 to select the shoe.
Categories B and C are wide shoes, so there are limitations on their use. When using these shoes, check the pre-
cautions, then investigate and study fully the conditions of use to confirm that these shoes are suitable.
When selecting the shoe width, select the narrowest shoe possible that will give the required flotation and ground
pressure. If a wider shoe than necessary is used, the load on the track will increase, and this will cause the shoes
to bend, links to crack, pins to break, shoe bolts to come loose, and various other problems.
