Bucket Passes to Dump Trucks



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.



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.





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





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.
