China had develop specialized trailer for over 40 years and had established some achievement, however, the discrepancy is still big compared with U.S. or E.U. Thelow loader trailer.
The detachable gooseneck lowboy trailer is comprised of hydraulic system, transmission system, alignment system and locking system. By triggering the separation unit in the gooseneck, the trailer deck can be separated or hooked from the front neck, enabling big construction vehicle, which had poor ability of slope climbing, to load or unloading from the trailer deck. For normal low loader trailer with rear ramps, the big sloping angle remains a big problem for those vehicles. The detachable gooseneck design perfectly solve this problem.
