The traditional low bed trailer can not meet the demand of long cargo transportation in many cases. As required, we design the extendable flatbed trailer according to different lengths of cargo. The cargo loading platform can be extended and retracted freely.

Forced steering is the most commonly used steering form for the extendable trailer, and knuckle steering is the most common form of extendable trailer steering for sale. It is important that the maximum steering angle can reach 45 degrees.

ADVANTAGES OF ALL WHEEL STEERING TECHNOLOGY ON EXTENDABLE TRAILER

Conform To Ackerman Steering Principle

According to the automobile theory, if the vehicle can turn normally, the value of the wheel angle must comply with the Ackerman angle theory, that is, the normal of each vehicle intersects at a point, which is called the steering center of the vehicle. When the vehicle turns, the all-wheel steering system on an extendable rgn trailer can make each wheel coordinate according to the angle value in Ackerman angle theory during the whole turning process of the vehicle, so that each wheel is basically in a rolling state during turning and driving. When a general vehicle turns, the wheel angle can not meet the value in Ackerman angle theory, so there is serious friction between the wheel and the ground in the process of turning. It shows a large turning radius and sideslip.

Reduce Tire Wear And Make Long-term Use More Economical

According to statistics, tire wear accounts for the main part of the operation and maintenance cost of extendable trailers. The selling price of a semi-trailer using all wheel steering technology is higher than that of an ordinary low bed semi trailer, but considering the long-term use, it is more economical because the trailer is in good condition, has fewer maintenance times, and less tire replacement times.

Reduce Steering Space

Compared with the semi-trailer whose wheels do not have steering function, the semi-trailer whose wheels have steering function needs less road width in the process of steering. the minimum turning radius of the hydraulic force steering is much smaller.
