Гусеничный экскаватор Caterpillar CAT excavator 325D 329D

Features of Carter 325D Excavator:

1: Engine
C7 ACERT, number of cylinders - cylinder diameter × stroke (6-110×127), turbo-aspirated, can provide a powerful power of 188 HP. The Cat C7 with ACERT technology offers better fuel economy and lower wear. It functions during combustion to optimize engine performance and reduce emissions. By combining ACERT technology with the new "Economy Mode and Power Control" system, customers can find a balance between performance and fuel economy to suit their needs and applications.

2: Hydraulic system

The pilot pump is independent of the main pump and controls the front connecting rod, rotation and travel operations. In all operating conditions, the hydraulic interactive induction system can utilize each of the two hydraulic pumps to achieve 100% engine power. This increases productivity with faster running speeds and faster and more powerful reversals. During boom lowering and rod retraction operations, boom and rod regeneration loops save energy, resulting in increased efficiency, reduced cycle times and pressure losses, higher productivity and lower operating costs, and improved fuel efficiency.
