Komatsu SDA16V159E-2 Engine

The Komatsu SDA16V159E-2 engine with 1119 kW (1,500 HP) gross horsepower delivers greater acceleration and higher travel speeds with a high horsepower-to-ton ratio. High torque at low speeds and impressive acceleration ensure maximum productivity with low fuel consumption. Standard features of this engine include: Pre-lube system designed to eliminate start-up wear and increase overhaul life.CENSE® on board monitoring of engine performance for each cylinder.

Advanced K-ATOMiCS with Skip-shift

The electronically controlled all clutch modulation system (K-ATOMiCS) optimizes the clutch engagement oil pressure at every gear. This system optimizes the clutch lock-up process for smoother shifting with minimal torque shock. The Skip-shift function, when driving uphill, automatically selects the gear according to the slope of the grade. This function reduces the number of down-shifts, making the driving smoother, improving the operator’s comfort and reducing potential material spillage.

Powershift Transmission

Komatsu’s HD1500-7 features a fully electronically controlled, automatic seven-speed powershift transmission. Main transmission features include: Electronic shift control with automatic clutch modulation in all gears.Transmission-mounted torque converter.Lock-up clutch system that is activated in every forward shift change.Separate hydraulic circuit and cooler.Rubber damper that reduces harmful engine shocks and torsional vibration to the transmission.

Automatic Retard Speed Control (ARSC)

ARSC allows the operator to set a desired machine speed according to the grade of the road. This function manages the speed of all four wheels, allowing adjustments of the desired speed on grade by using the options available in the ARSC lever.

Propulsion Performance Chart

To determine travel speed during propulsion using this travel performance chart: Read from gross weight down to the percent of total resistance. From this weight-resistance point, read horizontally to the curve with the highest obtainable speed range, then down to maximum speed. Usable rimpull depends upon traction available and weight on drive wheels.

Suspension

The linkage arrangement utilized in the MacPherson independent front suspension system allows the front wheels to smoothly follow the undulation of the road surface, providing excellent riding comfort.

Rear LED Lighting Rack

An LED lighting rack at the rear of the truck provides rear, brake and flasher lights. In addition, this bracket, protected from falling objects by the body structure, includes the back-up warning horn and warning lights.

Steering System

The MacPherson front suspension system has a special A-frame between each wheel and the main frame. The wider space created between the front wheels and the main frame increases the turning angle of the wheels. The turning radius of the HD1500-7 is 12.2 m 40’, which provides excellent maneuverability in tight loading and dumping conditions. In addition, a secondary steering system provides emergency hydraulic power in the case of sudden loss of engine power or steering hydraulic pressure. The steering accumulators comply with ISO-5010 standards.

Automatic Spin Regulator (ASR)

During slippery conditions, the traction control provided by the ASR detects and corrects wheel spin on rear tires by applying braking force independently to the drive wheels. The ASR operates independently of the service brake system, providing an additional means of controlling the machine in slippery conditions.

Auxiliary Brake and Automatic Application

All four wet disc brakes are activated when the auxiliary brake button, located on the dashboard, is pressed. In addition, the brakes will be automatically applied when the hydraulic pressure drops below the specified level.

Service Brakes

The HD1500-7 comes standard with four-wheel, hydraulically actuated, oil-cooled service brakes. By using a fully hydraulic braking system, the formation of water and sediments - typical in air actuated braking systems - is no longer present. This helps prevent contamination, freezing and corrosion from affecting service brake component life. The HD1500-7 stopping distance is well within ISO 3450 braking standard.

Hoist Cylinders

The newly designed three-stage cylinders deliver smooth and reliable dumping by using an internal cushion valve and over-center damping. Internally, the cylinders have a quill assembly that modulates the body return speed after dumping. This reduces forces transferred to the frame, body and suspension cylinders.

Simple and Reliable Hydraulic System

The hydraulic system is a proven and reliable design with fewer parts than other OEMs. The system utilizes a single tank, providing one common source of fluid for steering, braking, and hoisting. In-line, replaceable filtration elements provide protection from hydraulic system contamination. This makes the system easier to service.

O-Ring Face Seals & Sealed DT Connectors

O-ring face seals provide superior leak protection. All hydraulic hose male connections have a straight thread and o-ring in the face. The female connections have a straight thread and machined flat face. Komatsu trucks use Deutsch connectors in main harnesses and controller connectors of its electrical wiring. Compact, hermetically sealed, resistant to temperature and vibration and easy to use, Deutsch connectors are designed to withstand the harshest and most challenging environments.

Customer Specific Body

Komatsu works with each customer to understand and meet all of the criteria for body capacity and distribution. The Komatsu Body Worksheet (BW) process obtains the appropriate information from the customer about key factors that will help to determine the correct body for their site. Komatsu offers a standard all-welded steel, flat floor body with an over the cab canopy and horizontal bolsters. Standard Body Struck Capacity: 54 m3 71 yd3 Standard Body SAE Heaped 2:1: 78 m3 102 yd3 Standard Komatsu Body Weight: 19100 kg 42,108 lbs.

Enhanced Frame Design

The HD1500-7 frame has been enhanced to meet more stringent Komatsu Engineering Standards (KES). This enhanced frame design focuses on improving stress distribution in order to offer superior strength. Furthermore, increased casting thickness in high stress areas provides the structural flexibility needed to carry loads and absorb impacts in the toughest haul road conditions.

Rugged and Durable Dump Body Design

The standard dump body is made of high tensile strength steel with a Brinell hardness of 400 for excellent rigidity and reduced maintenance cost. The side and bottom plates of the dump section are reinforced with ribs for additional strength.

Ergonomically Designed Cab

The Komatsu HD1500-7 cab provides a comfortable and productive environment to meet today’s mining market demand. The cab includes tinted glass windows, heating and air conditioning, acoustical insulation, double sealed doors, and pressurized air filtration system. The instrument panel makes it easy to monitor critical machine functions. Machine events are recorded and indicated as service codes. A caution light warns the operator of any problems that may occur. This makes the machine more user friendly and easier to service.

Automatic Lubrication System

The automatic lubrication system is designed to reduce service downtime and improve durability of all pin joints by having a centralized module that automatically distributes grease at adjustable intervals. In addition, this hydraulically activated system can be adjusted to deliver the precise amount of grease required by each joint.

KOMTRAX Plus

As part of a complete service and support program, Komatsu equips every truck with KOMTRAX Plus. By using a satellite-based communication system, KOMTRAX Plus provides access to machine health parameters and trends, payloads, and critical faults in a user friendly web interface. The information available through KOMTRAX Plus allows service personnel to review faults and trends, improve the quality of the troubleshooting process and reduce unscheduled machine downtime.
