29. INTRODUCTIONS OF ATTACHMENTS 29.3 SELECTION OF TRACK SHOES Select suitable track shoes to match the oerating conditions. METHOD OF SELECTING SHOES 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 precautions, 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.
