Get to know the Productivity Features of the Komatsu HD785-7 Mining Truck
United Tractors, Jakarta – Komatsu is a well-known truck and heavy equipment manufacturer from Japan that has been worldwide since its founding in 1921. Komatsu produces various types of reliable heavy equipment used in the mining industry, such as mining trucks. The mining truck produced by Komatsu is a type of off-highway dump truck with 6 different variants.
Off-highway dump trucks are truck type heavy equipment that often operate in mining areas. The function of this truck is to move materials ranging from soil, mining products, to rocks in mining areas.
Behind the cabin, there is a vessel or open tub that can move up and down with hydraulic assistance. This hydraulic system is used to facilitate the process of lowering or spilling material to the destination point.
Komatsu has various off-highway dump truck variants with different specifications. The specifications of each dump truck can be adjusted to suit your needs. Even though the specifications are different, they all have the same function, namely as a mining truck that transports, loads, and moves heavy materials around the mining area.
Komatsu off-highway dump trucks have 3 main features: productivity features, dash features, comfort features, and operator control. Specifically for this discussion, we will discuss the productivity features of the Komatsu HD785-7. The following is a complete review of the features of the Komatsu HD785-7, which can increase work productivity in the field.
Komatsu HD785-7 Productivity Features
Productivity features on the Komatsu HD785-7 mining truck consist of a high-performance engine, VHPC mode options, Auto Retard Speed Control, and many more. For a complete discussion, below is the review.
- Komatsu SAA12V140E-3 Engine Powered 879 kW (1,178 HP)
The SAA12V140E-3 engine type installed on the Komatsu HD785-7 produces faster acceleration and higher movement speed. Technologies such as the HPCR (High-Pressure Common Rail) injection system and efficient turbo-charged air-to-air aftercooler enable this engine to achieve EPA Tier 2 emissions certification.
This engine also has high torque at low speeds. Plus, the acceleration is also impressive and the fuel consumption is low, so the overall productivity of the machine is guaranteed to be maximum.
- Equipped with Variable Horsepower Control (VHPC)
Variable Horsepower Control is a feature that allows the operator to determine the system’s mode of operation. To save excess engine power output, VHPC can help the operator activate the appropriate mode so that the mining truck function can be implemented properly without reducing performance.
The two modes that can be set using VHPC are Power Mode and Eco Mode. The power mode is suitable for application in difficult terrain with the capacity of the Komatsu HD785-7, whose vessel is fully loaded. This is caused by power mode which makes the machine work optimally so that the resulting production is optimal.
Eco mode itself is a mode that is suitable for use when the truck is empty or not loaded. This mode does provide full engine power, but only at a lower level to minimize excess fuel consumption.
- Equipped with the F7-R2 (RH/RL) Fully Automatic Transmission
Looking for an automatic mining truck with high work performance? Komatsu HD785-7 is the answer! This unit has an F7-R2 (RH/RL) fully automatic transmission. Full automatic control is applied to all 7 forward gears and 2 reverse gears selectively and optimally, according to travel and engine speed.
The Komatsu HD785-7 is also equipped with 2 reverse gears RH and RL, which can adjust the conditions when the unit is operating. RH is used during normal operations. The locking clutch on the RH makes the engine reverse at high speed. Meanwhile, RL is suitable for application when the truck is on a sloping and steep surface.
- Equipped with AP-FOUR (Anti-Pitching 4-wheel Oil-Cooled Multiple Disc Retarder)
The Komatsu HD785-7 has AP-FOUR, which is a feature that can slow down the four wheels on the unit. The function of AP-Four on mining trucks is to reduce the possibility of tire locking and increase the effective use of retarder capacity. So, even though the unit is on a downhill lane, the truck’s stability can still be maintained, and it does not experience a significant slope.
- Auto Retard Speed Control (ARSC)
Auto Retard Speed Control (ARSC) is a mining truck speed control system that allows the operator to regulate the truck’s speed. If the capacity of the mining truck is full, the driver must be able to control the speed of the truck well, especially when on extreme routes such as downhill roads.
With ARSC on the Komatsu HD785-7, the driver will be free to regulate speed. The speed that can be adjusted by this ARSC system is in multiples of 1 km/hour, 0.6 MPH per click (±5 km/hour, 3.1 MPH) for consistent and optimal speed results on downhill routes.
- Automatic Idling Setting System (AISS)
To prevent overheating of the engine, the Komatsu HD785-7 automatic dump truck comes with an Automatic Idling Setting System (AISS) feature, which provides facilities in the form of engine heating and cooling or even heating the cabin quickly.
How it works when this system is turned on, the engine idle speed will remain at 945 rpm when the coolant temperature reaches 50 °C (122 °F) or lower. Then, the engine idle speed will return to the 750 rpm position when the coolant temperature rises above 50 °C (122 °F).
- Has a Narrow Turning Radius
The front suspension on the Komatsu HD785-7 is a MacPherson Strut type with a special A frame that sits between each wheel and the main frame. With this A-frame, there is more space between the front wheels and the main frame. That way, the wheel turning angle becomes wider. The wider the turning angle, the narrower the truck’s turning radius.
- Has a Long Wheelbase and Wide Tread
The extra-long wheelbase, wide treads, and extremely low center of gravity of the Komatsu HD785-7 mining truck enable the unit to transport its loads at higher speeds. With high speed, work productivity can be maximized. Not only that, the long wheelbase with wide treads will also provide superior driving comfort, even when operating on difficult terrain.
- Large and Stocky
Just like heavy mining equipment in general, the Komatsu HD785-7 off-highway dump truck also has a large size with a sturdy body. In terms of overall size, this heavy equipment looks large, especially the vessel part, making the material loading process easier and neater. The larger and wider the capacity, the more efficient the transportation process will be.
Those are some of the productivity features of the Komatsu HD785-7 dump truck. As the name suggests, the features mentioned above are the main ones that provide support for increasing truck work productivity in the mining sector. Work targets will be more easily achieved if the heavy equipment used has productivity features and other features, such as those found on the Komatsu HD785-7 truck.
