EX1200
Impressive Productivity
More production thanks to Hitachi's cutting-edging technologies
Production: Approximately 9% Increase (H/P modes)
(vs. conventional model with BE front)
Advanced Hydraulic Technologies
Boom Recirculation System
Pressurized oil is efficiently recirculated in the boom circuit, assisted by the boom self-weight when the boom lowers. This design delivers more pressurized oil to the arm from the pump to increase arm lowering speed in combined operation of the boom and arm.
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 rollout speed can be increased greatly. A variable throttle, provided in the arm circuit, adjusts the oil flow in combined operation with arm roll-out.
Boom- and Swing-Priority Modes
The boom- or swing-priority mode can be selected for higher production.
Boom-Priority Mode
When swing angle is small in a cycle of digging, swinging and dumping, boom raise speed increases to reduce a cycle time.
Swing-Priority Mode
When swing angle is large in a cycle of digging, swinging and dumping, swing speed increases to reduce a cycle time.
Three work modes can be selected by setting the switch to the three positions below.
Position 1: Boom-priority mode
Position 2: Normal mode
Position 3: Swing-priority mode
Boom Mode Selector
The two boom modes, comfort and powerful modes, can be selected according to job needs, extending the service life of the machine. When the boom mode selector is On, the comfort mode is selected for efficient excavation, while the selector is Off, the powerful mode for productive excavation.
Improved Performance
Increased Boom Lifting Force
The boom lifting force is increased to easily lift large rocks on quarries and mines.
Boom lifting force:
Approximately 8% increase
(vs. conventional model with BE front; arm positioned vertically and bucket resting on ground)
Improved Mobility
Mobility is improved to achieve sharper steering with more traction force.
Traction force:
Approximately 14% increase
(vs. conventional model)
Increased Digging Force
Digging force is increased for powerful excavation on quarries and mines, using the BE or standard front.
Improved Swing Performance
Swing performance, even on a gradient, is improved for efficient trenching for piping laying, and for wall excavation using the bucket side.
Swing torque:
Approximately 8% increase
(vs. conventional model)
Excavation Closer to Machine
The front linkage is redesigned to allow the front to excavate closer to the machine for well combination with dump trucks.
(vs. conventional model)
