Mitsubishi S6S-DT Engine Strong and Stable Lower Frame

Transmission The six cylinders, turbo-charged, charged air cooled, engine is built for power, reliability and economy.This engine meets EPA tier ll and EU stage ll emission regulation. Reinforced box-section frame is all welded, low-stress, high-strength steel. It guarantees safety and resistance against external impact when driving on rough ground and working on wet sites through high tensile strength steel panels, with highly durable upper and lower rollers and track guards. Long undercarriage incorporates heavy duty excavator style components. X-leg type center frame is integrally welded for maximum strength and durability.

Automatic Engine Overheat Prevention Reliability You Can Depend On

Mitsubishi S6S-DT engine is idealsolution for the toughest work enviroment.The engine is built from a cast iron, skirted block with main bearing support between each cylinder. This combination provides maximum strength, rigidity, and crankshaft support. Special liquid cooling results in uinform temperature distribution. If the engine coolant temperature gets too high, the CPU controller lowers the engine speed and cools the engine.

Anti Restart System

The new system protects the starter from restarting during engine operation, even if the operator accidentally turns the start key again.

Track Rail Guide & Adjusters Advanced CAPO System Arm Flow Regeneration System

Durable track rail guides keep track links in place. Track adjustment is made easy with standard grease cylinder track adjusters and shock absorbing springs. The Advanced CAPO(Computer Aided Power Optimiation) system maintains engine and mutual pump power at optimum levels. Mode selections are designed for various work loads and maintaining high performance while reducing fuel consumption. Features such as auto deceleration and power boost are included in the system. The system monitors engine speed, coolant temperature, and hydraulic oil temperature. Contained within the system are self diagnostic capabilities which are displayed by error codes on the cluster. Arm flow regeneration valve provides smooth arm-in operation without cavitation.

Compact Engine Size Power boost control System

The compact sie of the engine makes it easier to service than other engines. The low engine height allows easy access for maintenance due to a side- mounted, gear-driven camshaft. When the power boost system is activated, digging power increases about 10%. It is especially useful when extrapower is temporarily needed, for instance,when digging hard earth and rock, or if the bucket teeth are stopped by a stubborn tree root.

Boom & Arm Holding System

The Holding valves in the main control valve prevents the boom & arm from dropping over an extended period in neutral position.

Reinforced Bucket and Bucket Linkage

Sealed and adjustable bucket linkage provides less wear of pins and bushes as well as silent operation. The design includes bucket link durability and anti wear characteristics. Additional reinforced bucket is made with thicker steel and additional lateral plate.

Auto Deceleration System Automatic Warming-up System

After the engine is started, if the engine coolant temperature is low, the CPU controller increases the engine speed and automatically increases the pump flow rate to warm up the engine more effectively. When remote-control valves are in neutral position more than 4 seconds, CPU controller instructs the accel actuator to reduce engine speed to 1200rpm. This decreases fuel consumption and reduceds cab noise levels.

Self Diagnosis System

The CPU controller diagnoses problems in the CAPO system caused by electric and hydraulic malfunctions and displays them on the LCD monitor of the cluster through error codes. This controller has the capacity to identify 48 distinct types of errors. As the information from this device, such as engine rpm, main pump delivery pressure, battery voltage, hyd. temperature, and the state of all types of electric switches, provides the operator with a much more exact state of machine operating condition. This makes the machine easier to troubleshoot when anything does go wrong.

One Touch Decel System Pump Flow Control System

In neutral position: Pump flow is reduced to a minimum to eliminate power loss. In operation: Maximum pump flow is delivered to the actuator to increase the speed. With movement of the control lever, pump flow is automatically adjusted and the actuator speed can be proportionally controlled. When the one touch decel switch is pressed, CPU controller controls the accel actuator to reduce engine speed to 950rpm. And then the one touch decel switch is pressed again, the engine speed recovers.

Powerful and Preciser Swing Control

Improved shock absorbing characteristics make stopping a precise and smooth action

Max. Flow Cut-off System

For precise control and finishing work, the Max. Flow Cut-off System reduces pump flow, thus allowing smooth operation.
