D400E Series II Ejector Truck Caterpillar

These inspections are particularly important for this type of machine as the machines can experience difficult work cycles.

Regular inspections can minimize the risk of accidents. Regular inspections can reduce down time.

The interval between these inspections depends on the factors that follow.

• The age of the machine

• The severity of the application

• The loads that have been carried on the machine

• The condition of the haul road

• The amount of routine servicing that has been carried out

These inspections should be carried out at intervals no longer than 1000 service hours or six months. Older machines, or machines that are operating in severe applications will require more frequent inspections.

If the machine has been involved in a collision, or if the machine has been involved in any kind of accident, the machine must be inspected thoroughly. Inspect the machine regardless of the date of the last inspection.

The machine must be clean before the machine is inspected.

Proper repair of frames and structures requires specific knowledge of the following subjects.

• Materials that have been used to manufacture the frame members

• Frame member construction
