Products DescriptionIt can be raised or lowered. Can be lifted in two aspects, one is through the trailer air bag can be lifted, reduce wear, save fuel, especially suitable for one-way empty car situation. Second, through the manual height valve in the air suspension system, the height of the vehicle loading platform can be adjusted within a certain range, convenient loading and unloading of goods.The air spring is filled with air and has compressibility.

Products DescriptionThe German type semi trailer suspension is widely used in the heavy-duty market at present, because its guide arm structure is similar to the traditional leaf spring structure, showing one-piece or multi-piece, usually directly forged, stronger load-bearing performance, and relatively longer travel of the air bag.

Products DescriptionCompared with ordinary semi-trailer axle, DARO 13T lowbed trailer axle with brake adopts 20Mn2 seamless steel tube with higher wall thickness. Not only the axle beam, but also the wheel hub, brake drum, friction plate and other accessories of the low flat truck axle are also dedicated, and the strength, toughness and wear resistance are all fully up to standard. Online + offline double quality inspection + ultimate performance test to ensure that the axle provides stable performance in complex environments.ModelMax.

Products DescriptionDARO 13T American type Trailer axle Beam is made of 20Mn2 high-strength alloy seamless steel pipe with standard wall thickness of 11mm and diameter width of 150*150mm. Integrated hot rolling molding process eliminates manual welding, and has stronger bending and torsional resistance and load-bearing capacity. Ensure the efficient operation of vehicles for a long time.ModelMax.

Products DescriptionDARO American type utility trailer axle beam:High load-bearing capacity: American style axles are made of high-strength steel or alloy steel, which have undergone precision machining and heat treatment, and have high load-bearing capacity.
