What piece of equipment must be used with the MHU-110 to prevent the trailer from becoming unstable while using the rail extenders for loading or unloading heavy munitions?

The MHU-110 is a specialized trailer used for transporting munitions, and ensuring stability during loading and unloading is crucial for safety. Stabilizer jacks are specifically designed to support the trailer and distribute weight evenly, preventing it from tipping or becoming unstable when heavy loads, such as munitions, are being handled.

Using stabilizer jacks helps to create a solid foundation, allowing crew members to safely operate the rail extenders without the risk of the trailer shifting unexpectedly. This is particularly important when handling heavy munitions, as the additional weight can significantly affect the center of gravity and overall stability of the trailer.

While safety chains, load binders, and wheel chocks serve important roles in securing the trailer and its load, they do not directly address the issue of stability during the loading and unloading process. Therefore, stabilizer jacks are essential for maintaining a safe working environment in this context.
