What equipment can be used to correct unacceptable bends in containers?

The adjustable wrench is a versatile tool designed for gripping and turning nuts, bolts, and fittings of various sizes. In the context of intermodal containers, it is particularly useful for making precise adjustments to hardware or fittings that may have been misaligned or bent. When a container has unacceptable bends, the adjustable wrench can help apply the necessary torque to reshape or tighten components back into their proper alignment.

While other tools listed may have specific uses, none are as well-suited for directly addressing bends in container structures. For example, a measuring tape is primarily used for measuring dimensions rather than correcting structural issues; a welder's hammer, while it can aid in metal manipulation, is more specific to welding tasks; and a container handler is designed for lifting and transporting containers rather than performing repairs. This focus on the direct application of the adjustable wrench to the adjustment and repair process makes it the correct choice for this scenario.
