Products DescriptionLeaf spring trailer axle，commonly known as leaf springs and steel plate bridges, they are mainly composed of leaf springs, suspension bearings (commonly known as lifting lugs), connecting rods, U-bolts, and other components. Their obvious advantages are simple structure, low cost of construction and maintenance, stronger rigidity, and higher bearing capacity. Leaf springs have a guiding function that can transmit forces and moments in various directions.

Products DescriptionAlthough the Fifth wheel is not an obvious part, it is a very important part. As an important assembly part connecting the tractor and the semi-trailer on the semi-trailer, the Fifth wheel not only plays the role of pulling the semi-trailer and bearing the load of the semi-trailer, but also should be able to withstand the start, acceleration, deceleration, steering, braking and other motion conditions of the tractor and the impact of hanging the semi-trailer.

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 DescriptionThe american type Independent trailer axle produced by DARO Group adopts 20Mn2 high-strength alloy seamless steel pipe as the raw material, with both strength and toughness reaching the standard and stronger load-bearing capacity. Brake drum, wheel hub, bearing, brake pads, bolts and other parts are used in the industry's leading brands, stable and reliable quality. Entering the market for more than 20 years, customers are highly praised.ModelMax.

Products DescriptionSemi trailer air suspension：(1) High driving safety:When the vehicle passes the concave and convex road, overtaking or steers sharply, the stretch or compression travel of the air spring is relatively large, and the stiffness increases rapidly to adjust the balance of the vehicle, so as to reduce the vibration and roll angle, improve the safety of the vehicle, and ensure the integrity of the transported goods.(2) Good driving comfort: Due to the small internal friction between rubber and air during operation, it can absorb high-frequency vibrations and generate less noise,

Products DescriptionDARO trailer container twist lock is specially designed and created for heavy container transport semi-trailers. The lock shaft has passed strict tensile and fatigue tests, and the physical and chemical properties of the material and parts have all passed the test, which can fully guarantee driving safety. With uniform specifications and diverse models, Can be perfectly applicable to all kinds of international and domestic containers.

Products DescriptionDisc brake trailer axles，developed and manufactured by Daro Group, the first vehicle bridge enterprise in the Liangshan Special Purpose Vehicle Production Base to mass produce integrated axles, the axle body and axle head are polished and formed on the same high-strength alloy steel pipe, which is superior to the welded axle head in terms of heavy load performance.

Products DescriptionTrailer axle dedicated Brake Shoe is designed to fully integrate the characteristics of the use of semi-trailer axle, higher strength, high hardness chamfered inserts, frequent braking is not easy to deformation.

Products DescriptionDouble axle enclosed trailer axle is the most widely used axle type on semi trailers, and also has the highest proportion in the current market. Compared to other axles, the most obvious advantage of drum type axles is that their prices are relatively low, their accessories are basically common in the industry, and their design is simple, making subsequent maintenance and replacement more convenient.ModelMax.

Products DescriptionDue to the low ground clearance of the DARO low bed braked axle,it is beneficial to reduce the center of gravity of the vehicle to a certain extent, making it easier to load and unload goods, and improving driving stability accordingly. When vehicles transport ultra high goods on the height limited road section, the trafficability will also be stronger.Secondly, the wall thickness and strength of the low flat axle are higher. Compared to ordinary semi trailer bridges, the 20Mn2 seamless steel pipe wall thickness used for low flat plate axles is higher.
