Inspect for Cracks or Damage and Repair
All earthmoving equipment is subjected to a high degree of wear and tear, which is why regular inspections for structural damage, and correct operation of all systems is necessary.These inspections are particularly important for off highway trucks, which can be subjected to very arduous work cycles.Regular inspections can minimize the risk of accidents and reduce down time.The interval between these inspections depends on factors such as the age of the truck, the severity of the application, loading, haul road condition and the amount of routine servicing which has been carried out.Older trucks or those in particularly severe applications will require more frequent inspections but, in general, it is recommended that these inspections should be carried out at intervals not exceeding 1000 service meter hours or six months.If the truck has been involved in a collision or any kind of accident it must be taken out of service immediately and inspected thoroughly, regardless of when the last full inspection was made.In order to carry out a proper inspection it is essential that the truck is thoroughly cleaned.Proper repair of frames and structures requires specific knowledge of materials used, frame member construction and manufacturers recommended repair techniques.If repairs are necessary it is recommended that you contact your local Caterpillar dealer who is qualified to carry out repairs on your behalf.Caterpillar do not advise that repairs are carried out by anyone other than a Caterpillar dealer but, if you decide to carry out your own repairs, contact your dealer for advice regarding recommended repair techniques.The front and rear frames, oscillating hitch and dump body should be thoroughly inspected for cracks and defects, particularly in welded structures.
The areas highlighted are of particular importance but other areas must not be neglected. The entire structure should be carefully examined.
