Precaution for track shoe selection
• Since working conditions "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.
