The traditional low bed trailer can not meet the demand of long cargo transportation in many cases. As required, we design the extendable 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 drop deck 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. Extendable Flatbed 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 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. Extendable Flatbed Trailer Helps Fuel Economy Compared with non steering semi-trailer and semi-trailer with the hydraulic steering system, semi-trailer with all-wheel active steering system has better fuel economy. HOW TO DEAL WITH SUPER LONG CARGOS? Most extendable lowboy trailer platforms with low loading and unloading surfaces can be extended laterally. This function is mainly realized by steel, aluminum, or wooden rotating arm or telescopic arm. On some heavy duty trailers, hydraulic lateral extend arms are also equipped. At present, a three- stage extension can be realized at most. Longitudinal extension inevitably requires the energy supply of the transmission device to extend in the same direction. To this end, a device called "energy chain" is most used today. By fixing the pipeline in the "energy chain", the damage to the pipeline caused by the lifting process can be effectively avoided.

Detach gooseneck trailer refers to a heavy-duty low bed semi-trailer with mechanical or automatic disassembly of the gooseneck of the trailer and the loading platform. The main purpose of this gooseneck detach trailer includes the ability to climb the earth moving machine from the front end of the trailer to the loading platform of the trailer. Detachable gooseneck trailer is used for transporting heavy loads and machinery. When using an ordinary low bed trailer instead of detachable lowboy gooseneck trailers, heavy goods are loaded from the mechanical ramp at the rear. However, when detached gooseneck trailer is used, the machines are loaded from the front load gooseneck trailer. Since removable gooseneck characteristics, heavy machines can be loaded from the front. The rgn removable gooseneck provides the convenience of loading machines from the front. WHAT ARE THE REMOVABLE GOOSENECK TRAILER CHARACTERISTICS When loading mechanical equipment on the low bed semi-trailer, mechanical equipment is usually loaded from the rear end of the semi-trailer, that is, the mechanical equipment is moved from the rear or the wheels are removed. This method not only has low loading efficiency, but also is prone to the problem of mechanical equipment turn over; When the trailer which detaches gooseneck passes the road section with obstacles above, it is particularly difficult for the trailer to pass because the cargo platform is fixedly connected with the gooseneck and platform; When encountering a curve road, due to the long overall length, the overall passing efficiency of the trailer is low. Although some semi trailers are equipped with steering devices, manual operation is still required, and the steering efficiency is still not high. Therefore, it is necessary to improve it. The Detachable Gooseneck Trailer realizes the height adjustment of the platform, ensure that the detached gooseneck trailer can quickly pass through the road with obstacles above, realize the linkage between the steering device and the truck through the steering mechanism, and improve the efficiency when the trailer passes through the curve. Through the detachable connection structure between the gooseneck and the loading platform, the goods in the hydraulic detachable gooseneck trailer can be loaded from the front, improving the loading efficiency and ensure safety during loading. Now the price of removable gooseneck trailer for sale and detachable lowboy trailer for sale is affordable, if you want to buy it, please contact us. We also provide types of heavy trailers for sale, anything you need, leave us a message.

After the rapid development of the wind energy market in recent years, the wind energy resources in the plain area with good construction conditions have almost been developed. At present, wind turbine heavy haul transport carriers are being transported to the mountainous area and sea with difficult construction conditions. However, the mountain roads are narrow and the turning radius is small. In order to effectively avoid the collision between the wind blade and the mountain, the wind blade must be transported in an inclined state. Therefore, Rui trailer's blade lifting appears in the market, and will greatly help for a transport company for such area to use. HOW DOES BLADE LIFTER TRANSPORT WORK Generally, in order to make the wind blade avoid obstacles more effectively, it is also necessary to make the blade rotate horizontally 360 °, so a slewing bearing is set between the blade lifter and the slewing platform. However, when the blade lifter lifts the blade, the center of gravity of the blade rises upward and moves to one side of the blade lifter. If the blade lifter wind turbine of the distance from the vertical line passing through the center of gravity of the wind blade to a certain point and the weight of the wind blade is the blade gravity distance, the gravity distance of the wind blade relative to the slewing bearing changes during the lifting process of the wind blade. In other words, the balance condition of the blade lifter is different under the horizontal and lifting state of the wind blade transport. This brings a problem, that is, if it is designed that the upper part above the slewing bearing is balanced when the wind blade is lifted by a certain angle, such as 30 ° (the center of gravity of the upper part is on the axis of the slewing bearing), the blade can rotate 360 ° when the blade is lifted by 30 ° or near, but if the blade is placed horizontally, one side of the blade is too heavy. When 360 ° rotation, the blade lifter can easily turn over to one side of the wind blade. If the upper part is designed to be balanced when the wind blade is placed horizontally, it can rotate 360 ° when the wind blade is placed horizontally. However, if the wind blade is lifted at a certain angle, such as 30 °, one side of the counterweight is too heavy. When turning 360 °, the blade lift is easy to overturn to one side of the counterweight. However, it is inevitable that the center of gravity will rise when lifting the wind blade. Therefore, how to make the center of gravity of the upper part only rise while the gravity distance relative to the slewing bearing remains basically unchanged or changes as little as possible is the problem that the blade lifter needs to solve. The simplest blade lifter is to hinge a swing frame on the rotary platform, set a pitch slewing bearing between the swing frame and the transition plate, fix the wind blade on the transition plate, and push the swing frame to swing around the hinge fulcrum through the lifting oil cylinder, which can lift the wind blade upward at a certain angle. At present, blade lifter in this special market mainly adopts three technical ways to solve this problem. First, increase the weight of the whole unit so that the weight of the rotating platform, blade lifter and wind blades, which change the weight of the loaded heavy moment, is relatively small, so that the change of the heavy moment of the whole unit is relatively small during the lifting process; The second method is to set the movable counterweight, that is, set the movable counterweight on the rotary platform, and move the counterweight automatically or manually while lifting the wind blade, so that the center of gravity of the upper part is basically maintained on the axis of the rotary bearing; The third is the method of moving the blade lifter, that is, setting a sliding slider and chute to make the blade lifter slide to one side of the slewing bearing while lifting the wind blade, so as to keep the center of gravity of the upper part basically on the axis of the slewing bearing.
