Hitachi Construction Machinery Co., Ltd. has announced that it has launched the ConSite® Health Check app, which enables service technicians to quickly diagnose the condition of construction machinery by using a smartphone. The app was developed as a new solution in the ConSite® package of service solutions aimed at reducing lifecycle costs, which is an important customer concern. ConSite® Health Check is capable of performing diagnosis and assessing the condition of construction machinery based on its operation sound and measurement data in the construction machinery industry. At the moment* it is the first in the industry with this capability.
The app will initially be made available to service technicians at dealers in Indonesia, the Middle East, and Africa starting in March 2020. The full-scale release to the global market will be implemented gradually at a later date.
The ConSite® Health Check app is equipped with functions that enable users with a smartphone to diagnose the condition of both the fuel injectors in the engine of construction machinery and the hydraulic pumps. As a result, “health checks” can be performed on construction machinery to identify degraded performance before a major failure occurs and takes the construction machinery out of service. Further, the app can help decrease the costs of downtime and maintenance.
The ConSite® Health Check app relies on technology that utilizes AI to detect and assess slight abnormalities in the sound of the construction machinery, along with technology that diagnoses conditions based on the mechanical characteristics of the construction machinery. Both of these technologies were jointly developed by Hitachi Construction Machinery and the Research & Development Group at Hitachi, Ltd.
ConSite® Health Check app features
- Quick “health check” with visualization of discrepancies in engine operation sound due to fuel injector deterioration
The ConSite® Health Check app enables quick on-the-spot diagnosis by using the microphone function of the smartphone to record the engine operation sound, and displaying the “health check” results in approximately three minutes.
- Quick “health check” that performs semi-automated measurement of hydraulic pump pressure
With the ConSite® Health Check app, the smartphone and construction machinery are connected to a communication device, and the pressure of hydraulic oil discharged by the hydraulic pumps is measured. The results indicate the condition of hydraulic pumps and the extent and progression of internal wear.
