Double drop trailers, also known as lowboy trailers, are specifically designed to transport heavy, oversized cargo. They feature a unique construction that allows for two drops in the deck, one behind the gooseneck and the other just before the wheels. (See “What is a Double Drop Trailer” for more info and the pluses/minus of a double drop trailer vs a step deck trailer). This design enables the trailer to maintain a low center of gravity, which is crucial for stability and safety during transportation. However, unhooking a double drop trailer can be challenging, especially for those who are new to handling such equipment. This comprehensive guide will walk you through the step-by-step process of unhooking a double drop trailer, ensuring a safe and efficient experience.
Safety First
Before beginning the process of unhooking a double drop trailer, it is essential to prioritize safety. Ensure you are wearing appropriate personal protective equipment (PPE), including gloves, safety glasses, and steel-toed boots. Furthermore, always ensure that the vehicle and trailer are parked on level ground, with the parking brake engaged.
Step 1 – Disconnect the Electrical and Air Lines
The first step in unhooking a double drop trailer is to disconnect the electrical and air lines. On certain types of Double Drop Trailers, you will also have a hydraulic line that would also need to be disconnected at this point. This is done to ensure that there is no power or air flowing through the trailer during the unhooking process. The electrical lines are usually located near the front of the trailer and are connected to the truck through a plug. You will need to disconnect the wires from the trailer and secure them on the back of your truck.
The air lines are usually located at the front of the trailer and are connected to the truck through 2 glad hands. To disconnect the air lines, you will need to release the air pressure from the system. Once the pressure has been released, you can disconnect the air lines from the trailer.
Step 2 – Put Landing Gear Down
The next step is to drop the landing gear to the ground. With a Double Drop Trailer, you don’t want to actually raise the trailer, you just want to crank the landing gear to the point where the feet of the dolly legs are lightly touching the ground.
Step 3 – Pulling the Kingpin
Once you are disconnected and dolly legs are down, you are ready to pull the kingpin. There is a handle on the fifth wheel plate that you need to pull. To make this process easier and safer, we offer a kingpin puller to keep you from having to reach down low and pull.
Step 4 – Drive Away
You should now be able to safely pull the truck away from the trailer. Drive ahead slowly to ensure that the truck and trailer disconnect from each other smoothly. Once you are clear, you are good to go. Safe travels.
Unhooking a fixed gooseneck Double Drop Trailer is a relatively simple process that requires attention to detail and careful preparation. By following the steps outlined in this article, you should be able to unhook a double drop trailer safely and efficiently. Remember to always take your time and to double-check that the trailer is stable before moving on to the next step. With practice, you will become more confident and proficient at unhooking a double drop trailer.
In the event that you are using a Removable Gooseneck Trailer (RGN Trailer) please check with the manufacturer for disconnection instructions as this is a much more complicated process.
