Drum Roller Compactor Inspection
Drum Roller Compactor Inspection
- Operator’s Station: The general condition of the operator’s station can give you a clue as to how the rest of the machine has been treated. Turn on the machine and make sure all gauges and instruments are in working order. Honk the horn, check the back-up alarm and turn on the lights. If the roller has dual amplitude or high frequency modes, check to see that all modes work.
- Engine: Check the drum shell thickness on both smooth drum and padfoot units. On smooth drum models, examine the drum for any pitting or scarring that can affect compaction smoothness. On padfoot compactors, note the condition of the feet, and whether a foot replacement is required.
- Tires: Measure the tread depth of both tires with a tire-measurement tool and check it against the guidebook specs for that particular brand of tire. Look for any major cuts or cracks.
- Articulation: Check to see if the articulation joint has been lubricated regularly, and the condition of the pins and bushings. Operate the machine to see if there is any excessive front-and-back flexing, which is a sign of over wear in this area.
