Heavy-Duty Rear Dump Semi-Trailer (30–100 Tons) | 3-Axle Mining & Construction for africa

A rear dump semi-trailer is a specialised transport vehicle widely employed for the hauling and discharge of bulk materials such as gravel, coal, sand, and construction aggregates. Its defining characteristic is the rear dumping mechanism, which enables materials to be unloaded efficiently from the rear end of the trailer. This semi-trailer is engineered to facilitate rapid and controlled unloading, significantly enhancing operational efficiency while reducing labour intensity and turnaround time. By allowing the cargo body to be hydraulically lifted and tilted, materials can be discharged directly onto the ground or into designated unloading areas, making the process both swift and reliable. Structurally, a rear dump semi-trailer typically consists of a tractor unit and a detachable trailer body. The trailer is connected to the tractor via a standard coupling system and is equipped with a robust lifting mechanism, most commonly powered by a hydraulic system. This system provides precise control over the tipping angle and unloading speed, thereby improving safety and operational accuracy, particularly in demanding working conditions. The principal advantages of rear dump semi-trailers include high payload capacity, superior unloading efficiency, and strong adaptability to diverse road and terrain conditions. Owing to their durability and versatility, these trailers are extensively utilised in the construction, mining, and earth-moving industries, where they play a critical role in ensuring the efficient transportation and discharge of bulk materials.
