The design of CSU structures takes into consideration the past operational data and experience to produce a robust design, however, depending on the material being handled and onoperating factors, the structure may experience unpredictable loadings. The Preventive Maintenance Program is designed to minimize such situations.

We at Sumitomo recommend our customers to put into place, a Preventive Maintenance Program, which includes Diagnostic Inspections, whenever we deliver equipment.

With our abundant preventive maintenance techniques, we are able to deliver effective Preventive Maintenance Systems.
In our system, the condition of the crane can be monitored on an on-site display, which constantly receives information from the crane electrical control system.

Further, by connecting the system to telephone lines, we can remotely monitor the crane conditions on our in-house Maintenance PC. The following parameters can be monitored in such a way.

1.Control of digging power
2.Accumulated load ratio
3.Vibration monitoring
4.Monitoring of PLC ladder program
5. Collect operational data
We are offering "Diagnostic" Inspections, using the latest techniques and equipment, to augment our 5 senses. Our Inspection Menu is shown below:

Installing the Remote Maintenance System enables customers to prevent trouble, recover quickly when trouble occurs, boost efficiency and save energy, dramatically reducing down time. Data can be collected separately by equipment unit, load distribution, torque distribution, speed distribution and other parameters. Changes in each of these variables can be visualized on a month-by-month basis.
Based on the collected data, trends in failure frequency can be visualized to show:
1) Peaks in cumulative failures in the past, 2) peaks in cumulative failures in the current fiscal year and 3) monthly peaks in cumulative failures.
Based on monitoring data, reports are prepared for each month and delivered to the customer quarterly.
Based on these reports, we also consult with the customer twice a year on equipment assessment.
