Semi-trucks are an essential part of the transportation infrastructure, carrying goods and materials to markets all over the world. But what many people don’t realize is that semi-trucks require a specific number of chains in order to operate safely.
The number of chains you need for a semi-truck depends on the size of the truck and the type of cargo it is carrying.
Heavy Duty Trucks
Heavy-duty trucks, also known as Class 8 trucks, are the largest commercial vehicles on the road and can weigh up to 80,000 pounds. These trucks typically need four chains: two at each axle. Each chain should be no more than seven feet long and have hooks, shackles or other attachments at both ends.
Medium Duty Trucks
Medium-duty trucks are smaller than heavy-duty trucks but still quite large, usually weighing around 33,000 pounds. These trucks usually require two chains: one for each axle. Each chain should be no more than five feet long with hooks, shackles or other attachments at both ends.
Light Duty Trucks
Light-duty trucks are smaller yet and can weigh up to 15,000 pounds. These trucks usually require only one chain: one for the rear axle. The chain should be no more than three feet long with hooks, shackles or other attachments at both ends.
To sum up, the number of chains you need for a semi truck depends on its size and type of cargo carried. Heavy duty trucks typically require four chains while medium duty and light duty trucks need two or one respectively. All chains should have attachments at both ends and be no longer than seven feet in length for heavy duty trucks to five feet in length for medium duty trucks or three feet in length for light duty trucks respectively.
