Caterpillar Japan Inc. (President: A.M. Bahaji President: Noriyuki Takeuchi), the quarrying, mining, construction, etc. to demonstrate competence in large-scale reclamation Cat 374D L hydraulic excavator (bucket capacity of 3.0m 3 , 70.5 Operating weight t) and the Cat 390D hydraulic excavator (bucket capacity 3.5m 3 , Operating weight 83.3 tons) of July 15 and launched from.

Large hydraulic excavators to launch two new models this time, Cat 365C L, respectively (2.9m bucket 3 , Operating weight 68.3 tons) Cat 385C and (3.5m bucket 3 , Operating weight 82.7 tons), machine model change, productivity further improved with features such as durability and superior conventional machines, and also to improve the safety and maintenance, are significantly higher in all aspects of product value for customers. It also meets the 2006 base year emissions gas road special motor vehicles, has the ability to clear the threshold for low-noise construction machinery ministry (pending), making it environmentally friendly products.

Cat 374D L and Cat 390D main features are as follows. The main features are as follows.

Key features of the Cat 390D Cat 374D L and

1. Productivity
374D L is mainly due to improved engine power up, the amount of work up to 13% per hour (compared to previous models) has been improved. 390D-up is due to improvements digging force, up to about 6% per hour of work (compared to previous models) has been improved.

Keep the engine speed corresponding to eight during the selection dial 10 dial “economy mode” introduces an. Fuel consumption, 374D L is about 11% (compared to the standard mode the aircraft), 390D was around 7% (compared to the standard mode the aircraft) to reduce.

374D L is the distance between the left and right crawler (crawler center distance) and to increase 5% and 8% the weight of the counterweight. And increased stability during operation.
