PRODUCTIVITY FEATURES
The PC300LC-7 utilizes a newly developed Komatsu SAA6D114E engine with air-cooled aftercooler.
This engine has high output, low fuel consumption and low emission.
(1) Large output
* The output in the catalog is 184 kW {247 HP}/2,000 rpm in the H/P mode, but only 177 kW {237 HP} is used normally. The
output is increased to 184 kW {247 HP} only when a large load is applied in the H/P mode.
(2) Low fuel consumption
Air cooled with the air-cooled aftercooler is supplied to the combustion chamber for higher combustion efficiency.
(3) Fuel consumption is improved by reducing hydraulic lossThe quick return circuit
is added to the arm cylinder bottom circuit. Since a part of the return oil is sent to the tank directly when the arm is moved IN, the hydraulic loss is reduced about 30% to reduce the fuel consumption and increased speed.

PRODUCTIVITY FEATURES
The high output engine combined with Komatsu’s proven HydrauMind system provides high production
and easy operation
What is HydrauMind?
The HydrauMind system symbolizes the new technology featured on the
Avance
series where the load sensing valves and pressure compensation valves handle all adjustments for individual work applications based on the
proportional pressure and lever stoke sensed. The load sensing valves are the “brains” of the avance excavators allowing full automatic oil flow control without the need for computer control in all operations.
Benefits of HydrauMind system
•
You can operate all work equipment easily and as desired.
•
For example, when the ground condition changes in digging, the required oil amount automatically flows to the actuators.
•
You do not have to worry about lever stroke or the computer program.
•
When moving the boom, arm and bucket at the same time, all equipment works, just like a human hand, at the optimum combination of speed and power without using any electronic device.
•
The finest controllability you have ever experienced.
•
Changing or adding valves and work equipment is easy.
1. Work equipment speed is determined only by lever stroke
Whatever the position of the work equipment control lever, all the oil flow from the pump goes to the actuator.Even if the load on the actuator changes, actuator speed remains the same.
2. Compound operations not affected by load
When two or more actuators are operated at the same time, the oil is divided and sent to each actuator corresponding to the lever stroke, regardless of the size of the load.There is no problem of excess oil flowing to the circuit at light load, and operations can be carried out simply in accordance with the operating feel.
Effective work using HydrauMind system
Fine control with lifting operations is easy. (for reason 1)
The amount the work equipment control lever is moved is constant, so it is easy to start movement without being affected by the size of the load being lifted.
Reverse scraping operations are easy. (for reason 1)
The arm can be moved slowly under full power, ensuring easy operation.

PRODUCTIVITY FEATURES
Work with additional attachments is easy (for reason 1)
Even when attachments such as breakers or crushers (which require a different amount of oil) are used, the flow of oil can be adjusted simply by adjusting the movement of the control pedal for the attachment (= spool operating area).
It is easier to fully load the bucket. (for reason 2)
During simultaneous operation, the work equipment moves slowly at maximum power, without being influenced by the other actuators, so it is easy to fully load the bucket.
It is easy to carry out digging work along the faces of walls. (for reason 2)
Lateral pushing is powerful allowing digging operations to be carried out efficiently.
The machine can carry out operations easily without any undue chassis vibration. (for reason 2)
During simultaneous operations, there is no change in the work equipment speed caused by change in load, thus, there is minimal chassis vibration.
It is easy transport fresh concrete. (for reason 1 & 2)
Fine control of compound operations can be carried out easily.
It is easy to scrape down. (for reason 2)
Even without operating the lever to the maximum position, maximum digging power can be obtained, making it possible to carry out slow control.
It is easy to operate the crusher and work equipment simultaneously. (for reason 2)
The oil flow is divided according to the movement of the lever, regardless of whether the load is heavy or light.
It is easy to dig soft rock or dig up boulders. (for reason 2)
It is easy to control the boom RAISE, so the cutting edge does not deviate from the boulders.

PRODUCTIVITY FEATURES
The tail swing radius is lengthened by 150 mm (5.9") and the counterweight is increased by 50 kg (110 lb.) to
improve the balance and stability of the machine.
1. Smooth mode
While gathering blasted rocks with the arm, lifting of machine front portion is prevented and shock due to machine falling is reduced. As a result, gathering material with arm is executed smoothly. (This is especially effective for gathering work from 1m (3'3") under-ground to the surface.) In addition, this is effective for scraping down facings loosened by blasting (dealing with floating stones).
2. Power mode
Boom pushing force is increased, ditch digging and box digging operation on hard ground are improved.

PRODUCTIVITY FEATURES
Drawbar pull increased
Drawbar pull is increased 34.3 kN (3500 kgf/7700 lb) by changing of final drive reduction ratio. PC300LC-7’s maneuverability on rough ground or slope is improved by improvement of travel performance.
Although the maximum drawbar pull is 431 kgf (950 lb.) less than CAT 330B, the drawbar pull per operating weight which is a reference index of the steering performance is larger.
Travel performance is improved by utilizing travel junction valve, increasing engine horsepower and drawbar pull.

PRODUCTIVITY FEATURES
Improvement of travel performance
When machine travels straight
Oil of the same quantity flows through the travel junction valve to both travel motors so the machine will travel straight.
When machine is steered
The travel junction valve is closed and oil flows separately to each travel motor, thus the machine can turn smoothly according to the operation of the travel lever.
When machine travels uphill (Operation of work equipment + Travel)
The travel junction valve is opened and oil of the same quantity flows constantly from 1 pump to both travel motors, thus the machine can travel and work simultaneously.
The travel junction valve is installed in the control valve to improve the straight travel performance, steering performance, and gradeability.

OPERATOR COMFORT
Automatic air conditioner
A 27,379 BTU (6,900 kcal) (SAE) air conditioner is utilized. The bi-level control function keeps the operator’s head and feet cool and warm respectively. This improved air flow function keeps the inside of the cab comfortable throughout the year.
Pressurized cab
The airtight cab is utilized to prevent entry of dust even in dusty environment. Since the airtightness of the cab is improved, the internal pressure is increased to 6.0 mmAq (0.2 inAq) when the air conditioner is operated (in the fresh-air-in mode).
The internal pressure of the cab of PC300LC-7 is increased to 9 mmAq (0.35 inAq) by employing the fixed one-piece glass for the front window. This internal pressure prevents dust from entering the cab.
The flanged floor mat is employed so that the inside of the cab can be washed with water. Since the floor inclines gently toward the door of the cab, water is drained easily. Additional water can be drained off through the draining holes at the front part of the floor under the mat.

The replacement interval of the oil and filters is extended by employing high-performance filtration material.
Since the high-performance filtration material has finer fibers and more pores, the dirt capturing capacity of the filter is increased.
(1) Hydraulic oil filterThe replacement interval is increased and the filter size is reduced by using microglass (high-performance filtration material).
(2) Engine oil filterThe filter paper is changed from the cellulose type to strata pore type having higher dirt capturing capacity.
