WORK MACHINE MAINTENANCE SYSTEM

摘要

This maintenance system is comprised of a hydraulic excavator (11) provided with a maintenance monitoring device (21), a maintenance management server (12) for managing trouble information and operating information for each working machine, a model information server (13), and a service personnel mobile terminal (14). The maintenance monitor device, the maintenance management server, the model information server, and the mobile terminal are connected through the Internet (15). When trouble occurs in the hydraulic excavator, the maintenance system (21) transmits trouble information to the maintenance management server (12), and the maintenance management server (12) transmits information on occurrence of trouble to the mobile terminal (14) and displays it on a display unit. This system manages the maintenance manuals and other data for each model in a model information database separate from the maintenance database and correlates the two databases based on the model data. This enables centralization of the maintenance work, reduces the work time for maintenance and repair, and raises the maintenance efficiency.
