Dump trucks cannot be replaced in logistics, transport, and engineering construction. From urban building sites via mine tunnels, and trunk lines running long distances to distribution runs short distances, the vehicles have varying performance and configuration requirements each time. So, to deliver dump trucks as effective equipment in operations, it is relevant to know the most important things involved in purchasing them.
I. Scenario Adaptation: The Fundamental Origin of Choice
1.Urban Construction
Urban construction involves hauling concrete and slag. This imposes rigorous requirements on the environmental friendliness and flexibility of vehicles. On city roads and alleys, cars must drive through narrow roads, height limit signs, and entry gates to building sites. For general urban use, vehicles with shorter wheelbases and under 2.5 meters in height work best. As far as emissions, cities usually require automobiles to pass the National VI standards. Compliant dump trucks alone can avoid operation restrictions caused by failing environmental regulations.
Good vehicle stability and sealing are needed in concrete transportation. In most cases, models with a chassis frame plane at 1050-1200 mm from the ground and 500-1100 mm rear overhang can be stable when driven. Besides, the carriage needs a good seal design. The design aids in preventing leakage while it is being transported, thereby promoting transportation safety and efficiency.
2.Mining Operations
The operational environment of open-pit mines is extremely harsh. Mountain roads and heavy loads put every part of a vehicle to the test. For example, the HoWo T7H dump truck is equipped with a 353KW/(480 HP) German MAN engine, it can climb slopes easily even when loaded to capacity with 70 tons of ore. The vehicle possesses an MCP23 T rear bridge and Hande front axle, accompanied by a high-strength chassis, giving it a load-bearing capacity far superior to normal models. Furthermore, the corresponding tires have a highly wear-resistant surface, which has a strong grip on muddy roads and gravel roads, allowing the vehicle to navigate these difficult roads with ease.
3.Road Transportation
Heavy-load long-distance transport is a kind of “endurance race” that imposes strict demands on comfort, fuel economy, and reliability of vehicles. The HoWo T7H dump truck’s gearbox has smooth gear shifting and easily adapts to various road conditions, significantly enhancing transportation efficiency. Apart from this, its considerate seating design, fine sound insulation, and reliable braking system make the driver feel comfortable during long-distance driving.
Short-distance transportation lays more stress on operating costs and vehicle flexibility. A 3-4 meter wheelbase light dump truck with a top hydraulic system will load and unload loads at high speed and efficiency. The vehicles are also comparatively low in acquisition and operating costs. Though their compartment volume is limited, they can be ideally suited to short-distance transportation due to their high-speed turnover advantage.
II. Configuration Selection: The Key Support of Performance
1.Engine
The dump truck’s engine is its “heart,” and the requirements for it have enormous differences according to different cases. In heavy-load transport for mines, powerful models such as the German MAN engine with HoWo T7H can ensure the power required by the truck. In short-distance highway transport and city construction, fuel-saving engines are sensibly selected to save costs. At the same time, newer engines with reduced market feedback need to be kept away as much as possible, instead, stable models that have undergone market testing for a longer duration should be emphasized.
2.Chassis
The chassis is comparable to the “steel skeleton” of the dump truck, which directly influences the carrying capacity and driving stability. For vehicles that often travel in complex road conditions, such as mine dump trucks, a high-strength chassis is required. HoWo T7H’s frame plane, ground clearance, rear overhang, etc., are well planned. It can carry a load of 70 tons with its capacity to adapt to varying road conditions. Some of them utilize oil-gas suspension. This adds to such trucks’ even movement under load.
3.Carriage
The material and structure of the carriage should be according to the nature of the transported goods. Generally, it is better to use 16Mn material because it has high strength and is acceptable in toughness. Secondly, loading and unloading efficiency also depends on the configuration of the carriage. For instance, if the back part of the bucket-shaped floor is hoisted, the slope angle is usually 12 degrees, and no rear baffle, which will unload more easily.
4.Hydraulic System
The selection of a hydraulic system is closely associated with the carriage length and tonnage. HoWo T7H is a large dump truck, so it uses a multi-stage front-top hydraulic system to smoothly lift and lower the car body under the 70-ton heavy load. In comparison, light dump trucks with a wheelbase of 3-4 meters tend to utilize a mid-top double-cylinder or single-cylinder hydraulic system. The structure is uncomplicated and inexpensive. Tripod-type hydraulic systems are applied in dump trucks with a wheelbase of 4-6 meters. The systems can generate a larger lifting force.
5.Tires
The choice of tires is related to safe and performance driving. For the operation in severe road conditions, such as mines, tires with improved wear resistance and traction should be applied. HoWo T7H fitted 12.00R20 tires reduce driving resistance and improve economy with a sure guarantee of bearing capacity. Road transportation can have the same tires that also bear the aspect of comfort and economy to reduce wear and replacement costs.
