Perkins 1206F-E70TTA

1206F is a turbocharged, air-to-air charged cooled, 7 litre, 6 cylinder unit capable of producing 205 kW (275hp). Its high power density, combined with excellent torque, Designed to meet EU stage Ⅳ, EPA Tier 4 Final and MLIT Step 4.

World-class manufacturing capability and processes coupled with proven core engine designs assure reliability, quiet operation, and many hours of productive life.

Turbocharging with smart wastegate available on all ratings for fast response, high power, and increased torque.

Cooling System

The parallel radiator makes cooling effect better and service easier.

Maintenance and Service 

The global after service of engine enables the sharing of global resources. This will enhance the service efficiency, relieve the customers’ worry and ensure the attendance rate of excavator.

Specialist of Engine Management

The engine speed allows 10 adjustable gears through the throttle potentiometer and achieves the precise management over the engine speed through the control of engine throttle by the DC servo motor. The engine allows the auto idling/acceleration function to reduce the fuel consumption. It has a function of touch power enhancement, can handle the high resistance working condition with ease.

Control Mode 

It adopts the advanced world positive flow control system to make the electronic control system, hydraulic system and engine always in a state of optimal configuration by the reasonable power matching. The automatic adjustment distribution of hydraulic system and power system can not only save energy and reduce cost, but also improve the working efficiency greatly.

Functions

This machine is equipped with the functions of straight travel, boom/arm confluence, boom/arm holding, swing priority, swing anti-reversing and regeneration of arm cylinder. Each circuit without interference during composite action. Digging of arm and bucket as well as the lifting and swing of boom at the same time during operating; the operations of left and right motors are independent during traveling.

Auxiliary Hydraulic Valve 

The main valve is provided with a set of standby valves to facilitate the installation of other accessories such as the breaking hammer.

Filtering System 

The hydraulic circuit is equipped with the high quality hydraulic oil filter which can prolong the service life of the hydraulic elements.

Components Layout 

The special design of hydraulic system and components location can enhance the system efficiency of the machine. The hydraulic oil tank, main pump and main valve are arranged closely to shorten the connecting lines and consequently reduce the line friction and pressure drop. The radiator is arranged at the right side behind the cab to effectively reduce the noise, hot air and exhaust received by the operator.

Pilot System 

The pilot pump is independent from main pump and supply oil to the pilot system which guarantee the stable and independent pilot control and facilitate the maintenance.

Monitor

The multi-purpose true color monitor allows the real-time monitoring and display of machine state, engine speed, coolant temperature, oil pressure and fuel level etc. 

Power Control Mode 

3 power modes of heavy-duty power mode (H mode), saving power mode (S mode) and light-duty power mode (L mode) can switch at will to reduce the power loss. The combination of 3 modes can reduce the fuel consumption and better meet the different working conditions.

Fault Auto Warning

It allows the fault self-diagnosis auto warning display and fault message save up to 99,000 pieces approximately to facilitate the fault call and inquiry during the maintenance of equipment. There are 3 levels of warning display according to the fault severity. 

Engine Overheating Auto Protection 

The overheating protection will be active if the coolant temperature exceeds 102℃. Then the engine will not flameout while the system will reduce the engine speed. However, if the coolant temperature is too high, the operator should shut down the machine as required and find out the fault causes. 

Low Oil Pressure Protection

When oil pressure below the standard value, the oil pressure switch will be closed, the text warning will display for 3 s and then the engine will slow down to low idle speed. In such a case, the operator should shut down the machine as required to protect the machine.

Maintenance Auto Remind 

The monitor will periodically remind the operator of changing the engine oil, grease and filter element at the set interval to support the routine service.

Main frame 

The reasonable layout of robust main frame optimizes the utilization of steels. 

Undercarriage 

The X-shaped undercarriage with heavy-duty box structure is subjected to the repeated finite element analytical calculation and enhance the overall rigidity, strength and torsional resistance. Undercarriage is welded from the low alloy structural steel plates with overall process quality control. The critical welds are fully subjected to fault detection and stress test to ensure the product quality.
