トン
"トン" (ton): Ton (a unit of weight) or the sound "ton."
The term "トン" here refers to a unit of measurement indicating weight, equivalent to 1000 kilograms.
彼は車を運転している間に1トンの重さの積み荷を運んでいた。
He was hauling a cargo weighing 1 ton while driving his car.
In this context, "トン" is used metaphorically to imply a large amount, similar to the English phrase "a ton of time."

Here, "トン" represents the sound or the act of something falling with a thud, imitating the idea of an object hitting the ground.
