2. What does a lowboy trailer look like?

A lowboy is a semi-trailer with two drops in deck height: one right after the gooseneck and one right before the wheels. This allows the deck to be extremely low compared with other trailers.

Lowboy trailers have a lower cargo platform that is positioned lower than the rear half of the trailer. This is known as a concave beam or a staircase structure. These trailers have a high degree of stability, as the staircase lowers the height of the center of the cargo platform. Lowboy trailers are generally used to move heavy equipment and other cargo that has a high height.

Gooseneck lowboy trailer features an adjustable gooseneck. This allows heavy equipment to be loaded onto either the front of the trailer. The adjustable gooseneck makes loading equipment from the front far easier. In addition, once the gooseneck is reattached, it will ensure that any items on the trailer will stay in place.

    The yield strength of HG60 steel is ≥620Mpa, which is the yield limit of the metal material when it is yielded,the yield strength is higher, then it's much stronger.

    So HG60 loading capacity is 5 times more than the trailer which is built by Q345 steel. Because the yield strenghth of Q345 steel is just 345Mpa

3. Side support’s thickness is 6mm, the distance of the side support is only 450mm. The side support firmly connect the main beam and side beam to improve the whole vehicle’s loading capacity, prevent the working platform to have cave the deformation.

4. The 3 axle lowboy trailer suspension width is 120mm, thickness is 10mm, and rotation pin of suspension we use 70mm. Ensure its have high loading capacity, and increase its capacity to twisting forces, shock, bump.

5. How does a lowboy work?

There are the major force-transmitting regions of RGN lowboy trailer. One of them is the main coupling responsible for transmitting the fundamental longitudinal towing forces between the trailer and the gooseneck. This coupling works as a single point in a force couple to keep the trailer frame and the gooseneck in their desired relative positions. 

There is yet another force vector of the same force couple usually transmitted through the thrust blocks in the back of the gooseneck. This essentially is a bearing surface of the lowboy equipment trailers frame at a point spaced backwardly. Hydraulic pressure is then supplied to the bottom part of the ram cylinders to facilitate the retraction of the rods. This creates a hydraulic lock between the trailer bed and the gooseneck. A lock pin is then used to make a positive link between the yoke pocket and the T-bar yoke.

Generally, this forms a positive connection from the yoke pocketed located in the trailer bed frame to the hydraulic ram anchor feature of the gooseneck. The effect caused helps in holding the thrust blocks tightly in position.

The safety hooks are engaged safely with their respective pins and the lock pins are used to keep the two key coupling hooks in a tight inter-fitting connection to prevent any accidental release.

During coupling and uncoupling, the lowboy trailer for sale assembly is let to a lowered position. During uncoupling, the safety pin handle gets puled and locked open to let the safety pin detach the T-bar yoke free from the yoke pocket.

The control lever for the hydraulic ram feature on the other hand is maneuvered to provide hydraulic pressure fluid inside the dram in order to lift the thrust blocks somewhat clear off their sitting positions on the main beam.

After achieving this, the lock finger gets retracted and the crank handle then is swung in an upward manner to anchor the safety hooks and the thrust blocks upwardly. Once this is attained, the lever is then locked in position through the lock finger that is fit in an upper coupling hole for the same.

Next, the hydraulic ram feature gets extended further to facilitate a further gooseneck rotation with respect to the RGN lowboy trailer bed. This is done to facilitate the withdrawing of the two lock pins that are engaged with the hooks.

The pins get swung in an upward manner through the use of the crank handle. On achieving this, the hydraulic pressure in the ram gets reversed hence allowing the pressure to go down in the cylinders’ bottom chamber. This action slowly lowers the gooseneck and the trailer bed to the ground.

You can choose to place a removable support block in between the trailer frame and the gooseneck beam in order to keep the gooseneck slightly off the ground surface. It is at this point when you can move the tractor away in order to give room for loading. 

And we have made a video of the specific operation steps of the detach trailer for sale for you, such as how to separate the gooseneck from the body, how to adjust the gooseneck height, etc.
