1. What is a removable gooseneck lowboy trailer?

Here I will highlight the removable gooseneck lowboy trailer for you.

Removable Gooseneck Lowboy Trailer (RGN): the removable gooseneck lowboy trailer falls into the category of lowbed semi trailer. Mainly used for transporting excavators, bulldozers, loaders and other large machinery and equipment. Removable gooseneck lowboy trailers with 2 axle, 3 axle, 4 axle, 5 axle and more axles are the most used vehicle models with loading capacities of 60/80/100/120/150/180 tons or more.

The characteristic of this kind of trailer is that the gooseneck is equipped with a power unit and a hydraulic device, which can quickly separate the gooseneck from the load-bearing platform, allowing the mechanical equipment to move from the front end of the trailer to the working platform, thus completing the entire loading process. You can do this by raising the trailer chassis as high as possible above the ground, depending on the height of the tow vehicle’s “fifth wheel.”

Relatively speaking, this loading and unloading method is faster, more convenient, safer and more reliable. It is your best transportation choice for excavators, bulldozers and other large and heavy machinery and equipment.

2. Two common structures of detachable gooseneck trailer.

Detachable gooseneck trailer have a wide range of applications. This vehicle was originally designed to load and transport heavy cargo without violating safety standards and without placing the driver in a dangerous transportation environment. For example, using traditional trailers to transport heavy machinery equipment and other goods, even if there is no height limit, will bring transportation risks due to the high center of gravity of the goods.

However, the transport performance of the detachable gooseneck lowbed trailer is more stable than other trailers. This detachable gooseneck design structure allows many lowbed transport trailers to more easily move large machinery and equipment and other cargo without violating height restrictions, and has a higher safety factor in situations, such as: large-angle turns.

YUHANG factory mainly serves the transportation of large and heavy goods, providing customers with the most economical, environmentally friendly and efficient transportation solutions. YUHANG is the best semi trailer manufacturer and service provider in China. The number of axles, load-carrying level, external dimensions and composition of our detachable gooseneck trailers can be deeply designed and customized based on actual transportation needs.

Ordinary detachable gooseneck trailer is mainly used to transport 50 ton, 60t RGN lowboy trailer for sale, 80 ton and 100 ton bulk cargo and 120 ton heavy machinery and equipment. The number of axles is generally 2 axle, 3 axle, 4 axle, or 5 axle for you to choose. The other type is a detachable gooseneck heavy-duty transport trailer, which is mainly 2 line 4 axle, 3 line 6 axle, 4 line 8 axle or 5 line 10 axle. The rear end of the vehicle has a “well-shaped” design structure and the tires are exposed. Its advantage is that through the “double drop” height, the overall height of the cargo loading and unloading area can be further reduced, making the center of gravity of the cargo lower and the transportation process safer. It can be used to transport a variety of heavy-duty and extra-long, extra-wide and extra-height cargo, including industrial equipment, oil and gas storage tanks, rail vehicles or oversized containers.

3. How do our detachable gooseneck semi trailer work?

Pay attention to detachable gooseneck semi trailer for sale near me. During the process of removing the gooseneck, you must first detach the front gooseneck of the trailer from the tractor saddle. The principle of operation of most types of detachable gooseneck trailers is the same.

The detachable hydraulic gooseneck consists of the traction section and base. Among them, the traction part has horizontal longitudinal beams (side longitudinal beams) spaced at a certain distance from each other, and the two are fixedly connected through a series of cross beams. The rear end of the traction part is inclined backward and downward at 45 degrees relative to the front end.

Connected to the front end of the gooseneck and the cross beam is a traction pin plate, on which is fixed a traction pin that is connected to the tractor saddle.

A mobile support is also included between the longitudinal beams on both sides of the traction part. The support includes a support arm with one end hinged to the cross beam and a cylindrical buffer at the other end. The buffer supports the frame at the rear end of the tractor saddle. Since the support arm is articulated, the buffer can be raised or lowered via a hydraulic cylinder connected to it. The control lever controls the expansion and contraction of the hydraulic cylinder through the oil circuit. When the hydraulic cylinder is extended and the support arm is lowered, the buffer supports the tractor frame and prevents the tractor part from rotating downward. This device can support the gooseneck during and after the separation of the gooseneck from the semi trailer to prevent it from rotating downward. Actuation of the control lever drives the hydraulic system to raise or lower the gooseneck of the support arm.

The bottom end of the gooseneck base is a flat surface that slopes forward and downward. This slope matches the slope of the front end of the semi trailer. The guide pin extending from the bottom end of the base can enter the area formed by the two guide plates at the front end of the semi trailer. At the front end of the gooseneck base near the bottom edge is a hole plate extending downward and beyond the bottom edge of the gooseneck base. The orifice plates are spaced a certain distance apart from each other, and the diameter of the circular holes on them can allow the protruding pin at the front end of the semi trailer to be smoothly inserted into the circular hole when the gooseneck is connected to the semi trailer. The stop pin shaft at the rear end of the gooseneck base passes through the fixing plate fixed on the base and is inserted into the stop pin hole on the semi trailer cargo bed to connect the gooseneck base and the semi trailer together.

Four hydraulic cylinders are hinged in parallel between the front end of the traction part and the top lifting lug in front of the base. Like traditional hydraulic cylinders, these four hydraulic cylinders are connected to the hydraulic system of the semi trailer through oil lines, and the telescopic movement of the piston rod is controlled by a control lever.

The gooseneck base consists of a pair of side risers fixedly connected by a top and bottom plate. The base is between the longitudinal beams on both sides of the traction part, and is hinged at the bottom end with the rear ends of the longitudinal beams on both sides through pins. The base can therefore rotate about a horizontal orthogonal axis relative to the traction portion.

The front end of the semi trailer is an inclined plane with a foldable slope on it. When the slope is turned down, it can be combined with the slope of the front end of the semi trailer to form a slope required for loading and unloading mechanical equipment. The distance between the two foldable ramps ensures that when the gooseneck is connected to the semi trailer, the gooseneck can enter the gap between the two without interference. At the front end of the semi trailer, a pair of forward protruding pins are fixed below the cargo platform plane. The pins can be smoothly connected to the orifice plate on the base of the gooseneck under the joint action of the guide pin and the guide plate.

Detachable hydraulic gooseneck lowbed semi trailers also include a safety lock system that prevents rotational movement of the base relative to the towing section. The safety lock system includes a cylinder connected by a pneumatic line and controlled by a control lever. The safety lock is controlled by the cylinder through a connecting rod system. Therefore, when the piston rod is extended, the telescopic pin is retracted into the inactive position, and when the piston rod is retracted, the telescopic pin is extended into the locked position.

As the gooseneck height decreases, the front bottom corner of the 80 ton removable gooseneck trailer lowers toward the ground and stays on the ground. Once all connecting components are safely removed, lower the cargo platform far enough to allow the tractor to tow the gooseneck. At this time you can easily load cargo from the detachable gooseneck semi trailer platform.

6. What is the difference between lowbed trailer and RGN lowboy trailer?

The feature of the hydraulic RGN lowboy trailer for sale is that it allows the gooseneck to be detached from the front of the trailer, so it is also called a front loading lowbed trailer. The loading platform of the detachable gooseneck trailer can be lowered to the ground, so more heavy machinery and equipment can be carried. However, ordinary lowbed trailer usually load cargo from the rear end of the vehicle through a mechanical ladder or hydraulic ladder, and its gooseneck cannot be detached. In this case, the application functions of the RGN lowboy trailer are very advantageous and can be easier for users to master.

Furthermore, you cannot lower the height of the loading platform when loading cargo on a lowbed trailer. This means that you cannot lift the cargo and load it onto the trailer without other auxiliary equipment. This will greatly limit the type of cargo you can transport, but it will not affect the proper functioning of the RGN lowboy trailer.

Due to these remarkable features, the RGN lowboy trailer for sale is easy to load and operate. This capability greatly increases the productivity and hauling value of a detachable gooseneck trailer over a lowbed trailer. Therefore, when faced with many over-height, over-wide, over-length, and over-weight cargo, many customers will first choose RGN lowboy trailer.

9. Folding gooseneck trailer VS removable gooseneck trailer.

Folding gooseneck trailer and removable gooseneck trailer are both a connection method for lowboy trailer, and the difference between them lies in the structural design of the connection part.

The gooseneck of the removable gooseneck trailer can be separated from the vehicle chassis to enable loading and unloading of mechanical equipment. Generally speaking, the detachable gooseneck lowboy trailer for sale have a stronger and more durable structure and can withstand larger loads.

The gooseneck of the folding gooseneck trailer can be folded and stored using a hydraulic control system. This connection method saves storage space and improves the working efficiency of the trailer. However, the load-bearing structure of the folding gooseneck is slightly weaker and cannot carry heavy loads. Therefore, when choosing a removable gooseneck trailer or a folding gooseneck trailer, it should be determined based on the specific use requirements of the trailer and the tonnage of the cargo.
