Translation guide
A sledge is a heavy sled or sleigh used for transporting goods or people over snow or ice. In Japanese, the most common word is そり, which covers sleds, sleighs, and sledges. For a heavy-duty cargo sledge, 大型そり or 荷そり can be used.
A vehicle on runners for traveling over snow or ice, often pulled by animals or people.
A large, sturdy sledge used for hauling heavy loads, often in polar or logging contexts.
Literally 'large sled', used to specify a heavy-duty sledge.
The loanword スレッジ (sledge) is sometimes used in specific contexts like 'sledge hammer' (スレッジハンマー), but for the vehicle, そり is the natural choice. Using スレッジ for a sled would sound unnatural.
