Most construction equipment owners today rely upon computers to assist them with their maintenance and operation controls. However, most are unaware of a ‘hidden’ data base available to the equipment manager: provided he is on an active lube analysis consulting program and provided appropriate software is applied. Far reaching decisions can be made concerning machine selection, operation, and disposal. The key is to systematically access the equipment data base, query the test results, and correlate these to recommendations from the maintenance department. This paper discusses an existing approach to accomplish this.
