Underground pioneer, no worries about load-carrying - 20-ton underground truck

Introducing the classification of underground mining truck

Underground  trucks play a vital role in mining and tunnel construction. According to different work requirements, operating environments and design characteristics, underground ore trucks can be divided into multiple categories. The main classification methods include power source, operation mode, load capacity, and specific application scenarios, which will be introduced in detail below:
Classification by power source Diesel-driven underground trucks: underground diesel trucks are widely used in underground mining and are mainly powered by diesel engines. They have strong power output and are suitable for transporting ore in long-distance and high-slope mine tunnels. In addition, diesel-driven ore trucks are usually equipped with turbochargers and exhaust gas treatment devices to meet strict emission requirements and reduce harmful gas emissions.
Electric underground trucks:  underground electric trucks are powered by batteries or external power supplies and use electric motors as driving force. The biggest advantage of electric ore trucks is low noise and zero emissions, which is very suitable for underground environments with poor ventilation conditions. They are generally equipped with large-capacity batteries and fast charging systems, which are suitable for frequent mine transportation tasks. The application of electric ore trucks is becoming more and more common, especially in mines with high environmental protection requirements.

Introducing the 20-ton underground truck 

The 20-ton underground truck is a heavy-duty vehicle specially designed for underground working environments such as mines and tunnels. It can carry 20 tons of ore or earth and stone, and adapt to the high-intensity transportation needs in extreme environments. This type of ore truck usually adopts a low chassis design to adapt to the narrow space and low clearance requirements in the mine. At the same time, it has a strong power system, flexible steering structure and reliable safety protection devices to ensure efficient and safe operation in complex and rugged underground working environments. This article will comprehensively introduce the characteristics and advantages of the 20-ton underground ore truck from multiple aspects such as equipment structure, power system, steering performance, safety protection and maintenance.

Equipment structure design
The structural design of the 20-ton underground  truck takes into account the low clearance restrictions unique to underground mines. Its overall body is usually relatively low and the vehicle width is smaller than that of conventional transport vehicles, so that it can pass flexibly in narrow mine tunnels. Its frame is made of high-strength steel and can withstand the harsh working conditions and high-load impact in underground environments. This design not only ensures the stability of the body, but also improves the durability of the vehicle. In addition, the bucket of a 20-ton underground ore truck is usually designed with a large volume and a self-unloading function, which is convenient for quickly dumping ore and reducing unloading time, thereby improving transportation efficiency.

Power system
20-ton underground mining trucks usually use diesel engines or electric drive systems to ensure that the vehicle has sufficient power in steep and rugged mine tunnels. Diesel engines usually use turbocharging technology to maintain strong power output under high loads. At the same time, modern diesel power systems are equipped with emission control technology to meet strict emission standards and reduce the impact of exhaust emissions on underground air quality. For electric-driven ore trucks, their battery capacity and endurance are stronger, and the electric system does not require an exhaust pipe, further reducing the impact on the mine environment. In addition, electric ore trucks can achieve low-noise operation, providing more comfortable conditions for the mine's operating environment.
In terms of power transmission, 20-ton underground mining trucks are usually equipped with automatic transmissions or electronically controlled transmission systems to ensure smooth acceleration and power transmission under complex road conditions. The transmission system also includes a powerful drive shaft and a high-performance differential, which can adapt to steep slopes, high humidity and complex rock environments. Through efficient power transmission, the 20-ton underground mine truck can improve the vehicle's traction and climbing ability while ensuring load capacity. 
Steering and suspension system
The steering system of the 20-ton underground mine truck usually adopts a full hydraulic control design with a small radius steering function to ensure that the vehicle can flexibly drive in narrow underground mine tunnels. The steering structure is generally articulated or rear-wheel steering, which can effectively shorten the turning radius and improve the vehicle's operational flexibility. The hydraulic system also has an anti-skid function and can maintain a stable operating state on wet, muddy or potholes. 
In addition, the suspension system of this type of mine truck usually adopts a hydro-pneumatic suspension or shock absorption system, which can effectively alleviate the bumpy feeling of the vehicle on uneven roads, ensure the comfort of the driver, and reduce the vibration loss of the mine truck caused by poor road conditions. The design of the suspension system can also effectively reduce the impact on the body and chassis and improve the durability of the vehicle.

Safety protection measures
Safety is the top priority in the design of underground mine trucks. 20-ton underground mining trucks are generally equipped with multiple safety devices, including emergency braking system, anti-skid system, fire protection system and reversing alarm device. The emergency braking system can brake immediately when the vehicle loses control or encounters an emergency, ensuring the safety of the driver and the working environment. The reversing alarm device can remind surrounding staff to pay attention to the direction of the vehicle to prevent accidents.
