Production equipment is an important part of the enterprise's fixed assets and production means, is to improve product quality, reduce product costs, improve economic efficiency to ensure.

Now the introduction and increase of advanced construction equipment, the serious shortage of skilled drivers and maintenance workers, resulting in the equipment out of warranty and out of repair, "sick" operation, abnormal collapse and other problems become more and more serious, the completion rate drops, affect the construction progress, have to buy or rent new equipment, forming a vicious circle. Mechanical equipment often because of the loss of maintenance, early wear parts, resulting in shortened life. Therefore, the maintenance of equipment is very important. With the continuous improvement of construction mechanization, equipment plays an irreplaceable and decisive role in construction and production. Bidding equipment, construction equipment, equipment is not only the hardware, and software, modern equipment is capital intensive equipment, equipment investment and use cost is very expensive, an urgent need to improve equipment maintenance, only to improve the quality of equipment maintenance work, in order to improve equipment intact rate, efficiency and productivity, reduce the equipment life cycle maintenance cost and other abnormal spending, reduce the cost, prolong service life, equipment maintenance is necessary and will be done, is the management of the equipment and perfect.

Good equipment maintenance during lean production can improve efficiency and output by reducing downtime. Keep equipment in good condition to reduce quality problems; Encourage staff participation and increase the sense of belonging.
