The 70-ton detachable gooseneck lowbed trailer is now undergoing a full structural strength test using 84-ton steel coils at Supro Trailer. This test is designed to confirm that every part of the trailer—its main beam, side beams, suspension points, and the detachable gooseneck mechanism—can handle heavy and concentrated loads safely. By using steel coils with higher weight than the rated capacity, the test simulates real working conditions such as transporting machinery, engineering equipment, or oversized components where weight distribution can be challenging.

The detachable gooseneck design also plays an important role during testing. It ensures that the trailer can maintain a stable connection while still allowing easy loading from the front, especially for equipment that cannot be lifted by crane. The low-bed structure keeps the center of gravity close to the ground, improving stability during heavy-load transport and making it easier to pass under bridges or through low-clearance areas.

At Supro Trailer, our focus is on practical performance and long-term reliability. The 84-ton test is not just about showing strength—it is about confirming that our customers can use the trailer in demanding jobs with confidence. Every trailer is built with attention to weld quality, material choice, and precise assembly, ensuring it performs well even after years of heavy work.
