Heavy Transport Trailers as special vehicle for heavy cargo logistics. The trailers normally have hydraulic suspension, which makes the vehicle have great bearing capacity and has hydraulic lifting function. It can finish the loading and unloading of heavy goods without lifting equipment. The trailer generally needs to be driven by truck, and the transportation speed is 30 ~ 60km / h, which can adapt to long-distance transportation. At present, there are many kinds of Heavy Transport Trailers on the market, such as modular hydraulic trailer, pendular axle trailers, bridge girder.
Follow up steering axle technology is more suitable for driving in complex road conditions, such as ODC transportation, heavy cargo transportation, wind energy logistics and so on. Under "critical" cornering conditions, the suspension system of the trailer is damaged and the abnormal consumption of tires is improved. According to official European test statistics, compared with traditional rigid axle trailers, the service life of tires of trailers with steering axles is twice that of the latter.
