What is the purpose of a converter dolly?

The primary purpose of a converter dolly is to couple one or two axles to a semi-trailer, allowing for the effective connection and stabilization of multiple trailers within a combined unit. This device plays a crucial role in ensuring that the trailers are securely linked to the towing vehicle, facilitating safe transportation of goods. The converter dolly also supports the weight of the trailers it connects and helps distribute the load properly across its axles, which is essential for maintaining balance and stability during travel. This device is particularly important in multi-trailer configurations, commonly seen in trucking operations, as it allows a single tractor to manage and maneuver multiple trailers efficiently.
