World-Class Productivity - To yield high production yet maintain low fuel consumption, such was the objective of the development of a new engine and hydraulic system for the ZAXIS 850 / 850LC / 870H / 870LCH.
- 14 % more bucket digging force and 8 % more arm digging force.
- (At power boost mode)
- (vs. Conventional Model)
- Enhanced Boom Recirculation System - In combined operation of boom lower and arm, arm speed can be increased by approximately 15 % over the conventional. Pressurized oil from boom cylinder bottom side is delivered to boom cylinder rod side to lower the boom, assisted by boom weight.
- Conventionally, pressurized oil from pump is delivered to boom cylinder rod side to lower the boom. The new system also allows an efficient combined operation of swing and lowering the boom.
- Combined Operation of Boom and Arm - In combined operation of swing + boom lower + arm roll-out, or in leveling (boom lower + arm roll-out), arm roll-out speed can be increased greatly.
- Here's why. A variable throttle, provided in the arm circuit, adjusts the flow when needed to reduce hydraulic loss in combined operation with arm roll-out.
- High Power Yet Low Fuel Consumption - 10 % Increase in output (vs. Conventional Model)
- 397 kW (532 HP) / 1 800 min-1
- The new clean engine, complying with the emission regulations Tier 3 in US (EPA) and EU Stage III, can reduce fuel costs by electronic control.
- Common Rail Type Fuel Injection System - Electronic control common rail type fuel injection system drives an integrated fuel pump at an ultrahigh pressure to distribute fuel to each injector per cylinder through a common rail.
- This enables optimum combustion to generate big horsepower, and reduce PM* and fuel consumption.
