RUBBER CRAWLER
Rubber crawler shoe maintenance
Rubber crawler shoe should be repaired or exchanged
under the next conditions.
If it is necessary to repair or replace it, contact your IHI
dealer.
•
Height of Lugs
The rubber crawler can be used even if it is worn,
however, if it is excessively worn, the crawler shoe is
likely to be slippery and more travel force is required. If
the remaining lug is less than 5 mm (approx. 0.2 in.) high,
exchange it with brand-new one.
•
Exposure of Steel Cords
If steel cord is exposed because of weary rubber or
damage, exchange it with brand-new one.
•
Cutting of Steel Cords of Rubber Crawler Shoes
When cutting of steel cord is detected, exchange it
immediately. If you leave it as it is, the rubber crawler
shoes can be cut off without expectation, which causes a
serious accident.
•
Crack of Covering Rubber
If a crack is 30 mm (1.2 in.) or more long and 8 mm (0.32
in.) or more deep, repair the cover immediately. If steel
cord appears even if a crack is small, repair it immediately.
Otherwise, water may come into a crack, which rusts steel
cords and cuts off the rubber crawler shoe.
•
Dislocation of the rubber crawler cores
Exchange the rubber crawler with a new crawler if one or
more cores are dislocated from it.
