371HP VS 400HP Dump Trucks: Which Power Configuration Is Better Suited for African Mining Transport?

In African mining transportation projects, the 371HP and 400HP are the two most common heavy-duty dump truck engine configurations, choosing the appropriate engine power for dump trucks not only reduce long-term operating costs but also improve transportation efficiency.

This guide will analyze the differences between these two power configurations from multiple perspectives, including horsepower definition, torque performance, fuel consumption, overload capacity, and overall cost-effectiveness, based on the actual working conditions of African mining transportation. Of course, choosing a dump truck that suits one's working environment depends not only on the engine power; the appropriate drive type is also very important, we will analyze the differences between 4X2, 6X4, and 8X4 dump trucks in the next guide.

1. What is HP?

HP refers to horsepower, which is an important indicator for measuring the output power of an engine, it reflects the amount of work the engine can accomplish within a given period, for heavy-duty trucks, horsepower affects the dump truck in the following aspects:

Vehicle acceleration capability

Speed retention capability under overload conditions

Performance on long uphill sections

 

2. What is torque?

Torque is the rotational force output by the engine crankshaft, it is the core metric for evaluating an engine's instantaneous power output capability and low-speed burst performance, torque determines:

Heavy-load starting capability

Gradeability

Stability under continuous load

In mining transportation, torque is often more important than horsepower.

Configuration reference:

Item	371HP	400HP
Engine Displacement	9.7 L	11 L
Maximum Torque	1500–1600 N·m	1800–2000 N·m
Gradeability	Good	Stronger
Heavy-load Start	Stable	More effortless

 

On flat roads or ordinary engineering transport, the difference in power between the two is not significant, however, in mining areas, the higher torque of the 400 HP engine will maintain better performance.

For example, on steep slopes and rugged terrain in mining areas, the additional torque enables the truck to:

Smoother starts under heavy loads

Reduced gear shifting frequency

Maintains steady climbing speed

Roads in African mining areas are often unpaved, this makes high torque particularly important in mining operations.

 

3. Which Chinese brand dump trucks are equipped with 371HP and 400HP engines?

Both SINOTRUK HOWO and SHACMAN are equipped with 400HP engines. HOWO is a classic model equipped with a 371HP engine, while SHACMAN is mainly equipped with a 380HP engine, which is close to the positioning of 371HP. In addition, some SHACMAN models are equipped with a 420HP engine, and BEIBEN dump trucks are equipped with 380HP and 420HP engines.

Below is the engine and dump truck model comparison table:

4. Fuel Consumption Comparison

Fuel costs account for a large proportion of operating costs in mining transportation, in generally, engines with higher power consume more fuel.

Reference example:

Assumptions：

371HP fuel consumption 34 L / 100 Km，400HP fuel consumption 39 L / 100 Km

Annual mileage: 60000Km

Diesel Price： 1 USD / L

Service Life：3 years

Estimated fuel cost: 

Item	371HP	400HP
Annual Fuel Consumption	20400 L	23400 L
Annual Fuel Cost	20400 USD	23400 USD
Three-year Fuel Cost	61200 USD	70200 USD

 

Therefore, the 371HP truck offers better fuel economy than the 400HP truck, however, fuel costs are not the only factor determining total operating costs, in mining transportation, the indicator of fuel consumption per ton-kilometer is more valuable for comparison.

Fuel consumption per ton-kilometer represents the amount of fuel consumed to transport one ton of cargo over one kilometer. This serves as the core metric for evaluating the fuel efficiency of dump trucks in mining operations.

 

Fuel consumption per ton-kilometer = Total fuel consumption ÷ (Total load × Distance traveled)

 

Take the 371 HP HOWO 6X4 dump truck and 400HP HOWO NX 8×4 dump truck as examples:

Assumptions：

371HP dump truck fuel consumption 34 L / 100 Km, load capacity of 30 tons.

400HP dump truck fuel consumption 39 L / 100 Km, load capacity of 40 tons.

Calculate fuel consumption per ton-kilometer:

371HP dump truck: 34 ÷ (30 × 100) = 0.0133 L / T·KM

400HP dump truck: 39 ÷ (40 × 100) = 0.0097 L / T·KM

The results show that despite the 400HP dump truck having higher fuel consumption, its greater load capacity results in lower fuel consumption per ton-kilometer compared to the 371HP model, making it more fuel-efficient.

 

5. Overload capacity

In many African mining areas, trucks often need to operate under harsh conditions, such as:

High-temperature environment

Long-term operation

Occasional overload

Under these operating conditions, engine durability becomes a critical factor.

 

The 371HP dump truck has the following features:

Proven technology

Reliable operation

Low maintenance costs

Applicable scenarios:

Potential reduction in mechanical wear

Potential improvement in long-term reliability

Thus, the 400HP truck is better suited for high-intensity mining operations, with applicable scenarios including:

Heavy-duty haulage in mining areas

Mountain roads

Long-term continuous work

 

Typical road conditions in African mining areas include:

Red dirt roads

Steep quarry ramps

Muddy terrain during the rainy season

To summarize in a simple table:

Configuration	Road	Applicable Scenarios
371HP	flat transport routes, moderate slopes	Medium-duty hauling, earthmoving projects, construction projects, short-haul freight
400HP	moderate slopes, mountain roads, steep mine shafts	Mining transportation, heavy-duty transportation

 

6. Cost-Benefit Analysis

When selecting dump trucks for their fleets, companies usually consider factors such as initial investment, fuel costs, transport capacity, maintenance expenses, and long-term reliability.

Comparison Table：

Factor	371HP	400HP
Purchase Cost	lower	slightly higher
Fuel Consumption	lower	relatively high
Overloading Capability	medium	strong
Climbing Ability	good	excellence
Long-Term Durability	good	better under overload conditions

 

Overall:

The 371HP model offers greater cost-effectiveness under moderate workloads.

The 400HP model delivers superior performance in demanding environments.

 

7. Case Analysis of Application in Different Mining Areas in Africa

 

Zambian Copperbelt 

In copper mining in Zambia, 371HP HOWO 8×4 dump trucks are widely used. The local mining company selected this configuration primarily based on: the moderate transport distance for copper ore, the road conditions are controllable, and the 371HP being sufficient to meet daily transport volume requirements, local maintenance personnel are familiar with HOWO models and maintain ample spare parts inventory.

 

Guinea Bauxite

Bauxite mining conditions in Guinea are even more severe, with 400HP dump trucks being mainly used, the reason why this mining area chooses 400HP is as follows: the roads in the mining area have a large slope and the road surface is muddy in the rainy season, so sufficient power reserve is required. Combined with the 16T axle, 10-speed gearbox, and mining-specific tires, it ensures the heavy-load climbing capacity.

 

Democratic Republic of the Congo

In the mining transportation sector of the Democratic Republic of the Congo, HOWO dump trucks with over 400 horsepower have also entered the market. A local customer once purchased a 400HP HOWO TX 8×4 dump truck from us, specifically for mining transportation. This reflects that as African mines develop on a larger scale, the demand for higher power configurations is growing.

 

Malawi

In Malawi, 400-horsepower dump trucks also play a vital role. Many mines use SINOTRUK HOWO TX 400HP 6X4 dump trucks, in specific markets, 400HP has become the entry-level or mainstream configuration for mining transport.

8. Key Factors in Procurement Decisions

When choosing between 371HP and 400HP, a comprehensive evaluation of the following factors is required:

Transportation Distance and Road Conditions

If it is for short-distance transportation in mining areas with gentle road slopes, 371HP is completely sufficient. For long-distance hauling or heavy loads on uphill sections, the 400HP engine offers a distinct advantage.

Annual Total Transportation Volume

For mines with large annual transportation volumes, choosing 400HP can reduce the unit transportation cost by shortening the cycle time and improving the attendance rate.

Accessory Supply Network

In regions with limited parts availability, opting for locally prevalent powertrain configurations is a more prudent choice, After-sales support is more important than the power parameters themselves.

Initial Investment and Return Cycle

The 400-horsepower model carries a higher purchase price, requiring calculation of whether the additional investment can be recouped within a reasonable timeframe through enhanced operational efficiency.

Fleet Uniformity

If the existing fleet is mainly composed of trucks with 371HP, continuing to purchase those with the same configuration can simplify the spare parts inventory and maintenance management, if you want to form a brand-new fleet, you can more freely choose the optimal configuration.
