The two shelves are suitable for the sichuanese line
I didn't go through the journey. But I have more than 30 self-drive experience. It seems to be structural and mechanically appropriate. But it is not suitable for the sichuan line. The support and force point of the one is the welding, the sichuan section of G318 or G317 is currently on the road, especially in the G318, which starts from the new bridge and reaches nearly to mango. That means there are a lot of roads, a lot of time, going on a bumpy road. At this point, welding will face serious challenges! Once you break, you will be helpless. And this kind of material and thickness, even if you're lucky, just breaking in a store doorway of welding equipment, large current welding equipment will be merciless Pierce your shelves in the wall. And the shop that has the welding equipment basically is in the county town, one county town is about 200 + kilometers from another county town, 3 to 400 kilometers, if the fracture how to support to? And two, the design that looks like the screw is easy to bump and loose. But change with self-locking nuts and increase spring washer can greatly reduce the loose and fall off, you have to do is take a wrench and take several sets of spare copies of the nut to prevent fall off loss, when you stop to rest or scenery tighten fastening. Looks like trouble, but there is a guarantee. There is no such thing as a complete strategy. On the road, just be careful and check your vehicles and equipment. Caution has made the ship.
The first one. Force aside. The key is to have fewer screws. It was a bumpy ride down the road, especially in the lower lancang river, and I saw several of my fellow riders on the shelf. Steel is durable and can be soldered at critical times.
The first is more uniform and more scientific.Which is the firm which is which.
