Excavator b.c.d what do you mean?
Type 1, A, produced 96 years ago,2, B type 96-2000 years of production,3, C type 01-07 annual production,4, D type 97-2013 years of production.Carter excavator is the world's largest construction machinery manufacturer in the world. Caterpillar Inc is one of the world's largest manufacturers of construction machinery. As an industry leader, Caterpillar has always been committed to global infrastructure construction, and has worked with its agents to promote positive and lasting reforms on all continents.
The problem is not with speculation, you ask a very likely refers to the similar 320B, 320C, Carter 320D, this BCD refers to the machine is the first of several generations of products, 320D is updating models behind the 320C, not all excavator manufacturers are represented by the letter, most are in the digital form, such as my most the Hitachi models are EX-1, EX-2, EX-3, EX-4, EX-5, ZX-1, ZX-3, ZX-3G, ZX-5G and other models.
Excavator b.c.d means the time period in which the production of different types of excavators is represented:1996-2000 annual production of 1, b;2, C type 2001-07 annual production;3, D type 1997-2013 years of production.Excavator, also called excavating machinery, is a kind of earthmoving machine that uses bucket to excavate material that is higher than or lower than the machine surface and is loaded into transportation vehicle or unloaded to the stacker. Excavators are mainly made of soil, coal, sediment, and soil and rocks that have been pre - loosened. From the development of engineering machinery in recent years, the development of excavator is relatively fast, excavator has become one of the most important construction machinery in engineering construction. The three most important parameters of excavator are operation weight (quality), engine power and bucket bucket capacity.
