Order also onSystematic care and attention are required to keep equipment in good working order, as well as regular maintenance and skilled repairs. In the construction industry, a general system of planned or scheduled preventive maintenance is used not only to keep equipment at its rated productivity and original accuracy but also to ensure its full and uninterrupted service. The essence of this system is to give each machine or mechanism regular inspection and various preventive repairs at definite intervals according to a schedule, in addition to routine daily maintenance. The length of the scheduled intervals, of course, depends on the specific features of the design of the equipment, its purpose, and its operating conditions. At any industrial enterprise this system has the following objectives:
(a) maintenance of equipment in a condition ensuring normal productivity and reliable quality of output;
(b) prevention of unexpected or accidental breakdowns of equipment;
(c) increase of productivity through improvements and modifications made during scheduled overhauls.
These objectives are achieved through two forms of maintenance:
1. Routine servicing between scheduled overhauls
2. Periodic scheduled repairs, consisting of minor and medium-scale repairs and major overhauls.
Routine technical servicing includes such basic tasks as the inspection and checking of the technical condition of assemblies and units and of the machine or equipment as a whole; routine correction of minor faults and adjustment of parts and mechanisms; lubrication, etc. This routine maintenance is the responsibility of the operators of the machines as well as of the maintenance service.
