Abstract

Excavators primarily perform digging, loading, and swinging operations, while travel operations are intended to support mobility within the work area and should not exceed the primary operations. The operational data of the PC210-10M0 excavator, accessed through KOMTRAX, was utilized in this study as part of Komatsu's monitoring service. The objective was to design, develop, and install a travel protection system (TREPOS) and analyze travel dispatch data as an indicator of travel operations. The TREPOS development process included system design, wiring diagram creation, assembly, installation, and system testing. TREPOS employs a Programmable Logic Controller (PLC) to process inputs and outputs. Its function is to provide an audible warning and reduce the engine speed to low idle if the travel operation exceeds 15 minutes. The PDCA method was used in travel dispatch data analysis as an evaluation tool for TREPOS development. Initial results indicated no reduction in travel durations exceeding 20 minutes, necessitating further improvements. The second installation showed a reduction in the number of travel durations exceeding 20 minutes from 13 to 8 occurrences.

Abstract

The operational pattern of excavator units, particularly travel duration and frequency, is one of the dominant factors contributing to the increased occurrence of undercarriage component breakdowns. Therefore, a system-based operational control mechanism is required to limit excessive travel operations that do not comply with manufacturer standards. This study aims to analyze the effectiveness of installing an additional controller in the form of a Travel Protection System (TREPOS) in a case study of a 20-ton class excavator as a preventive maintenance strategy to improve the reliability of undercarriage components. The research employs an integrated analytical approach comprising Failure Mode and Effect Analysis (FMEA), PDCA, and PICA, along with a comparative analysis of operational data before and after TREPOS implementation. The results indicate that excessive travel duration and intensity are among the dominant factors causing unscheduled breakdowns in the undercarriage system. The implementation of TREPOS effectively controls the unit’s operational pattern by reducing continuous travel time exceeding 20 minutes and suppressing the occurrence of unscheduled breakdowns during the study period. Furthermore, TREPOS implementation has the potential to extend the service life of undercarriage components by up to 48% for carrier rollers, 42% for track rollers, 33% for sprockets, and 86% for track links, which overall contributes to a reduction in maintenance costs.
