Large Dollies

The word “dolly” may also refer to a larger piece of equipment than a hand dolly. It can be a small trailer that can be hitched to a truck or another trailer. This sort of dolly is designed to support a semi-trailer. These dollies are equipped with a fifth wheel to which either the truck or the semi-trailer is coupled. In most states, this dolly will need independent rear lights and a registration tag plate.

There are two basic types of trailer dollies. One is a convertor dolly, which has between one to three axles and that are designed to hitch to a towbar. This is attached either on the rear of the pulling truck or front of the trailer. This may be an “A-dolly” with a single drawbar and a centered coupling, or, a “C-dolly” with two separate couplings installed side-by-side each other.

A low loader dolly is equipped with a gooseneck drawbar hitch which is attached to a fifth-wheel coupling on the pulling vehicle. This will share the load on the fifth wheel of the dolly between the pulling vehicle and the dolly wheels. Usually, these are only fitted with two axles.

Dollies are popular in Northern Europe, which has laws that allow longer vehicle combinations than in the remainder of the European Union. This type of dolly allows a semi-trailer to be attached like a regular trailer to the pulling vehicle.

A tow dolly is a handy item for folks who are moving or on vacation with a camper. This device will have little more than two wheels and an axle and a tow hitch. This dolly used to tow a car, usually front-wheel drive suspension vehicle, behind a recreational vehicle like a camper or other larger vehicle like a moving truck.
