The side lifter trailer has a unique side loading and unloading function, which can complete the loading and unloading of goods without the help of additional loading and unloading equipment. The vehicle is equipped with a hydraulic side-lifting device, which can easily lift and carry containers, large machinery and equipment and other goods, greatly improving loading and unloading efficiency and saving operation time and cost. The body is made of high-strength aluminum alloy material, which not only reduces the weight of the vehicle, improves fuel economy, but also enhances the corrosion resistance of the vehicle and prolongs its service life. The side loader trailer is easy to operate, and the driver can complete the loading and unloading operations in the cab, which improves the safety and convenience of the operation and is widely used in ports, logistics centers and other places.
