煉鉄的高爐,煉鋼的轉爐、煉油的分餾塔、造船的船塢設置等大型的生产設备,我們称它們为重型設备。軋鋼厂里的軋鋼机、發电厂里的各种發动机和發电机、汽車厂里的鍛压机以及制造上面所說的那些重型設备和机器的工作母机等,都称为重型机器。有时候也把重型机器和重型设备統称为重型設备。重型設备本身都非常龐大沉重。因为它的制造是一件复杂繁重的工作,而需要的数量又不很多,所以在一般情况下,不是成批地,而是單件地生产。單件生产是制造重型設备的生产特点。
Refining the blast furnace, steel converter, refining fractionation tower, shipyard dock setting and other large-scale production equipment, we call them heavy equipment. Rolling mills in rolling mills, various engines and generators in power plants, forging presses in automotive plants, and work machines that make heavy equipment and machines like those mentioned above are called heavy machines. Heavy machinery and heavy equipment are sometimes collectively referred to as heavy equipment. Heavy equipment itself is very large and heavy. Because it is a complicated and burdensome job to manufacture and not much needed, it is not normally produced on a mass basis, but in a single piece. A single piece of production is the production of heavy equipment manufacturing features.
