Description

Technical Field

[0001] The utility model belongs to the technical field of trailer tools, and in particular relates to a limiting device for a low-bed semitrailer. Background Art

[0002] Low bed semi-trailers are usually used to transport heavy vehicles or other heavy goods.

When transporting vehicles, common limiting devices include tie straps and ropes. This is because the wheelbase and other data between various vehicles are different, resulting in the inability to use limiting devices of the same specification. Only freely adjustable limiting devices such as tie straps and ropes can be used. Such devices are not only prone to loosening during bumpy transportation, but also more complicated to operate during installation and disassembly. Utility Model Content
