HITACHI CONSTRUCTION MACHINERY

30% Increase in Production*
*Compared to EX1100-3 using BE front and S/P mode.

More Powerful Engine
The source of the high production.
The EX1200 is equipped with a powerful large-displacement engine. An intercooler is used to provide optimal fuel efficiency, helping to keep total running costs down.

• 412 kW (560 PS) -> 482 kW (655 PS)
  EX1100-3
  

Larger Bucket
Provides high work capacity.

The large capacity bucket offers an increased excavating power-to-bucket-width ratio. The result is increased work efficiency for higher production.

• Backhoe bucket:
  3.0 m3 (3.92 yd3) - 5.6 m3 (7.32 yd3)
  

• BE bucket:
  5.6 m3 (7.32 yd3) - 7.1 m3 (9.29 yd3)
  

 

More Powerful Excavation
Increased power for excavating.

The powerful engine is combined with a highly efficient hydraulic system to offer ample excavating power for even the toughest sites.

Maximum Excavating Force

9.1 m (29' 10") boom/3.4 m (11' 2") arm with

• General purpose bucket:
  457 kN (46,600 kgf, 102,700 lbf)
  

• Rock bucket:
  475 kN (48,400 kgf, 106,700 lbf)
  

7.55 m (24' 9") BE-boom/3.4 m (11' 2") BE-arm with

• General purpose bucket:
  550 kN (56,100 kgf, 123,700 lbf)
  

• Rock bucket:
  550 kN (56,100 kgf, 123,700 lbf)
  

Combined Front Operations, fast and efficient operation.

The popular Optimum Hydraulic System (OHS) is used along with the newly developed arm regenerative and boom regenerative mechanism for smooth and efficient front operations.

E/P Control
Provides a balance between economical operation and power.

Speed sensing control is used to efficiently control engine output. This system incorporates a microcomputer to regulate engine and hydraulic pump output to the level of work being performed.

• S/P mode increases productivity
  Choose the S/P mode to boost power during strenuous operation.
  

• E mode reduces fuel consumption
  This mode lowers fuel consumption during light-duty operations.
  

 

Auto Idle and Quick Idle
Help to reduce fuel consumption even further.

 

Heavy Lifting Function
Increases boom lift performance by 10%.

The touch of a button gives the added power for breaking up rock or working under harsh conditions.

 

 

Boom and Arm
Designed for durability.

A box-section structure has been adopted on the front attachment for its large cross-sectional area. In addition, bulkheads arranged inside the front attachment increase rigidity to resist torsion, further strengthening the structure. The enhanced durability will be especially welcome for extended operation at tough work sites such as mines.

1. Boss lubrication type

2. Larger thicker bracket

3. A large pin diameter is used and a wear-resistant plate has been added to the sides of the arm at the arm end boss section. Pin service life has been extended by using a floating pin.

4. Larger pin diameter and wider arm mount width

5. Plate and square bars to help prevent arm denting.

6. Larger center boss

7. Larger pin diameter and boom foot width
