PRODUCTIVITY FEATURES
Electric Dynamic Retarder
The 2387 kW 3,200 HP retarding system provides state of the ar t braking capacity for navigating today’s mining applications which contain steep continuous descents and shar p switchbacks The continuous retarding capacity enhances the productivity of the vehicle operator, while eliminating the need for excessive mechanical braking effor t
IGBT AC Electric Drive System
Inver tex II® AC control system offers independent control of the rear wheelmotors, which in tur n provides outstanding traction-ability dur ing wet and slipper y conditions, thus improving tire wear and operator confidence.
The air cooled Insulated Gate Bipolar Transistor (IGBT) inver ter system technology provides the highest available reliability The IGBT inver ter is more compact and much simpler than the design of its predecessor, the Gate Tur n Off (GTO) inver ter, which improves ser viceability and routine maintenance
Traction (Spin-Slide) Control
During slipper y events caused by inclement weather conditions and/or application severity, the wheel Spin-Slide technology will detect and correct any wheel spin control events. Spin-Slide Control operates automatically and independently of the ser vice brakes During propulsion, "wheel slip control” reduces non-productive wheel spin in low traction conditions During retarding, "wheel slide control” prevents wheel lockup and subsequent sliding
Automatic Speed Control
While in retard or propel, the operator has the ability to select a comfor table travel speed. Automatic Speed Control simultaneously manages the speed of each wheel independently to allow for any immediate adjustments needed dur ing slipper y underfoot conditions
Customer Specific Body
For all tr ucks, Komatsu goes through the Body Wor ksheet (BW) process to ensure that each body is designed to meet the requirements for each specific application while carr ying its rated payload. Komatsu wor ks with each customer to understand all of the mater ial proper ties at a mine site and to identify the appropr iate liner package
Komatsu offers a standard all-welded steel, flat floor body with a full canopy and hor izontal bolsters This body includes a dr iver side eyebrow, body up sling, and r ubber mounts on the frame
• Standard Body Struck Capacity: 117 m3 153 yd3
• Standard Body SAE Heaped 2:1: 148 m3 193 yd3
• Standard Komatsu Body Weight: 28169 kg 62,100 lbs
Tight Turning Radius
By using double acting hydraulic steer ing cylinders with a sixpoint ar ticulation linkage, the power steer ing system provides steer ing control with minimal operator effor t The tur ning radius is 13 6 m 44' 6", which provides excellent maneuverability for tight load g and dumping conditions The steer ing accumulators comply with ISO-5010 standards 13 6 m 44'6" radius 13 6 m 44'6" radius
Payload Meter III® (PLM III)
PLM III is an electronic system that monitors and records payload infor mation for Komatsu’s off-highway mining tr ucks The accurate and reliable payload measurement system is designed to help optimize payload, maximize productivity and reduce the life cycle cost of the machine. PLM III tracks and records the following key production parameters:
• Payload
• Empty Carr y-Back
• Operator Identification
• Haul Cycle, Loading, Dumping Time and Date
• Distance Traveled (Loaded and Empty)
• Cycle Time Infor mation
• Maximum Speeds (Loaded and Empty)
• TMPH Estimate for Front and Rear Tires
• Average Speed (Loaded and Empty)
Example of Payload Summary
Hydropneumatic Suspension
Hydrair II® is a suspension system that utilizes four nitrogen-over-oil cylinders This suspension system is designed to maximize machine productivity by providing the operator with a smooth and comfor table r ide By absorbing shocks to the chassis dur ing operation, Hydrair II® contr ibutes to the durability of the machine’s frame and components.

OPERATOR ENVIRONMENT
Ergonomically Designed Cab
The Komatsu 730E cab design provides a comfor table and productive environment to meet today’s mining demands. The cab includes tinted windows, heating and air conditioning, acoustical insulation, double sealed doors, and provides filtered and pressur ized air
Operator Seat
Komatsu recognizes that operator comfor t is a key to productivity in today’s mining environment The five-way adjustable operator seat and the tilt-telescopic steer ing column provide an optimum dr iving posture for increased operator comfor t and control over the machine The air suspension seat absorbs vibrations transmitted from the machine, reducing operator fatigue A 76 mm 3" wide three-point seat belt is provided as standard equipment.
Automotive Style Instrument Panel
The 730E comes with a new operator fr iendly dash configuration which includes lighted gauges, switches, and infor mation panel This allows the operator to see the status of the machine dur ing operation and infor ms them of any faults An instr uctive message will appear after any fault is detected on the machine

RELIABILITY FEATURES
Structurally Enhanced Frame Design
By using advanced computer-aided design, finite element analysis, and full-scale dynamic and static testing, the frame design has been str ucturally enhanced to carr y 181 tonne 200 shor t tons and provides the highest reliability in the industr y
Simple and Reliable Hydraulic System
The hydraulic system is a proven and reliable design with fewer par ts than other OEMs. The system utilizes a common tank, and therefore, common fluid for steer ing, braking, and hoisting In-line, replaceable filtration elements provide additional hydraulic system protection from contamination
To keep downtime to a minimum, Komatsu developed a sub-frame pump module that can be removed and replaced as a single unit This reduces change-out time and allows easy access to the hydraulic pump module
Castings Used in High Stress Areas
To increase frame reliability, steel castings have been incor porated at key frame pivot points and key load bear ing cr itical por tions of the frame This includes the rear body pivot and horsecollar sections
Steering and Brake Accumulators
In the event that the hydraulic pressure in the steer ing or braking system drops below an acceptable minimum, nitrogen-charged accumulators will automatically apply the brakes so that the tr uck may be stopped There are separate accumulators for the braking and steer ing systems
GEB35 with Combo Brake
The GEB35 is a proven wheelmotor design based on the GEB25 and 788 It has a standard gear ratio of 30 8:1 and is designed for 12% equivalent grades
Fully Hydraulic Dry Disc Brakes
The 730E comes standard with four-wheel hydraulically actuated dr y disc ser vice brakes By using a fully hydraulic braking system, the for mation of water and sedimentstypical in air actuated braking systems - is no longer present This prevents contamination, freezing and corrosion from affecting ser vice brake component life
*Stops in 81% of ISO 3450 allowable distance

Payload Policy
10-10-20 Load Policy Criteria
Recognizing that var iation occurs naturally in mater ial density, fill factors, and loading equipment, Komatsu Amer ica Cor p deems it necessar y to establish a consistent payload policy This payload policy is intended to identify the guidelines and limitations for the loading of Komatsu mining tr ucks, and is valid for approved applications and haul profiles only
1) The average monthly payload must not exceed the rated payload of the tr uck
2) 90% of all loads must be below 110% of the rated payload of the tr uck
3) 10% of all loads may be between 110% and 120% of the rated payload of the tr uck
