What makes the ZX345USLC-6 and ZX245USLC-6 such popular machines? Along with other benefits, these excavators feature Hitachi’s exclusive TRIAS II three-pump hydraulic system that maximizes multifunction operation and delivers some of the fastest cycle times in the industry.
Check out the system features:
A. The TRIAS II hydraulic system consists of three pumps and valves. The pumps are controlled electrically for precise oil flow and lower fuel consumption. When demanded, the third pump supplies additional hydraulic oil to the swing circuit without stealing oil and speed from other functions. This maximizes multifunction productivity without sacrificing fuel economy.
B. The oil flows separately to the bucket (light blue), arm (dark blue) and boom (yellow) cylinders.
C. The front attachment moves faster, because each actuator has its own pump.
Contact your local Hitachi dealer and put TRIAS II to work for you.
