When you transport large freight, there are many types of semi trailers to choose. The more freight you transport every time, the more efficient you are, the more you earn every time. We want to introduce another type of transportation that can help you transport more freight every time. It is a semi trailer dolly.
A semi trailer dolly is an unpowered trailer which can be attached to trucks and semi trailers. They don’t carry a load but are used to support a semi-trailer or similar haulage unit. There are two common semi trailer dollies in the market: convert semi trailer dolly and low loader semi trailer dolly.
Convert semi trailer dolly
They have a forward connected drawbars, which can be coupled to the rear of a semi trailer. They can connect multiple trailers to form a combination of road-trains that can transport more freight each time
Low loader semi trailer dolly
They use kingpins instead of drawbars to attach to the trucks, so the trucks’ wheels won’t be overweight. Because there have more axles, the semi trailers can be loaded with heavier loads, and this also improves transport efficiency.
