Caterpillar introduces three mid-sized hydraulic excavators to launch the D-Series line. The 324D L, 325D L and 330D L excavators are said to feature greater performance, flexibility and versatility than the C-Series machines. The new excavators also deliver the lowest engine emissions ever through the use of Cat[R] engines with ACERT[TM] Technology. A new spacious cab and new styling also set the D-Series apart from previous machines. Each has more engine power and increased hydraulic pressure for increased breakout force and greater lift force, which create faster cycle times and superior productivity, www.cat.com.
