Definition
In simple terms, a dolly on a tow truck is a heavy-duty attachment designed to secure, lift, and transport vehicles. It consists of a sturdy frame equipped with straps or holders to secure the tires of the vehicle being towed. Towing dollies come in different types, each serving a specific purpose and offering unique advantages.
Types of Tow Truck Dollies
There are several types of tow truck dollies available, depending on the towing needs and the size and weight of the vehicles being transported.
- Two-Wheel Tow Dollies: These dollies are designed to lift and tow the front two wheels of a vehicle, while the rear wheels remain on the ground. They are commonly used for front-wheel drive vehicles.
- Four-Wheel Tow Dollies: These dollies are designed to lift and tow all four wheels of a vehicle. They provide more stability and control during transport and are often used for four-wheel drive or all-wheel drive vehicles.
- Car Carrier Dollies: Car carrier dollies are large, heavy-duty attachments that can transport entire vehicles, including vans and trucks. They are designed for heavy-duty towing and are equipped with additional features to ensure the safe and secure transport of large vehicles.
- Heavy-Duty Dolly Systems: These dolly systems are specifically designed for towing heavy-duty vehicles such as buses, RVs, or construction equipment. They are equipped with extra support and reinforcement to handle the weight and size of these larger vehicles.
Function
The main function of a dolly on a tow truck is to lift and secure vehicles for safe transportation. It provides a stable platform for the wheels of the towed vehicle and allows for controlled movement during towing.
When a vehicle is unable to move on its own, a dolly can be attached to the tow truck. The front or all four wheels of the disabled vehicle are lifted onto the dolly, and the tires are secured with straps or holders. This allows the tow truck operator to safely tow the vehicle without causing further damage or instability.
Components of a Tow Truck Dolly
To effectively perform its function, a tow truck dolly consists of various components. Understanding these components is essential for proper operation and maintenance of the dolly.
- Main Frame: The main frame of a tow truck dolly provides the structure and support for the vehicle being towed. It is typically made of durable steel or other heavy-duty materials to withstand the weight of the vehicle and the stress of towing.
- Tire Straps or Holders: These components secure the tires of the towed vehicle to the dolly. They are adjustable and can accommodate different tire sizes to ensure a secure fit. Tire straps or holders prevent the towed vehicle from shifting or moving during transportation.
- Ramps: Ramps are used to load the disabled or damaged vehicle onto the dolly. They provide a gradual incline for the wheels to roll onto, making it easier to lift the vehicle. Ramps are often detachable for convenient storage.
- Lights and Reflectors: To ensure visibility and safety on the road, tow truck dollies are equipped with lights and reflectors. These lights alert other drivers to the presence of a towed vehicle and indicate the direction of travel.
- Stabilizing Mechanism: A dolly may have a stabilizing mechanism, such as adjustable legs or supports, to provide additional stability and prevent tipping during towing. This is particularly important when towing larger or heavier vehicles.
- Hydraulic or Electric Controls: Some tow truck dollies are equipped with hydraulic or electric controls to assist with lifting and lowering the dolly. These controls make it easier for the operator to maneuver the dolly and adjust its height as needed.

Towing Capacity
When using a dolly on a tow truck, it is essential to consider the towing capacity. Towing capacity refers to the maximum weight a dolly can safely tow without compromising its stability or performance.
- Weight Restrictions: Each dolly has a weight limit that should not be exceeded. It is crucial to know the weight of the vehicle being towed and ensure it falls within the specified limit of the dolly. Exceeding the weight limit can lead to equipment failure or unsafe road conditions.
- Different Dolly Capacities: Tow truck dollies come in various sizes and capacities to accommodate different types of vehicles. Smaller dollies may have a lower weight capacity suitable for compact cars, while larger and heavy-duty dollies can handle larger vehicles, such as trucks or SUVs.
- Considerations for Heavy-Duty Towing: When towing heavy-duty vehicles, such as buses or construction equipment, specialized heavy-duty dolly systems are required. These systems are designed to handle the increased weight and size of these vehicles and are equipped with additional support and reinforcement.
Advantages of Using a Dolly on a Tow Truck
Using a dolly on a tow truck offers several advantages for both tow truck operators and vehicle owners in need of assistance.
- Versatility in Towing Various Vehicle Types: Tow truck dollies provide the flexibility to tow different types of vehicles, including front-wheel drive, four-wheel drive, and all-wheel drive. This versatility allows operators to meet a wide range of towing needs.
- Improved Handling and Stability: By lifting the wheels of the towed vehicle onto the dolly, the weight distribution is more balanced, resulting in improved handling and stability during towing. This reduces the risk of accidents or damage caused by unstable towing conditions.
- Cost-Effective Towing Solution: Tow truck dollies are a cost-effective alternative to flatbed tow trucks. They require less equipment and maintenance, making them a more economical option for towing companies. Additionally, dollies can be easily stored when not in use, saving space and reducing costs.

Disadvantages of Using a Dolly on a Tow Truck
While there are numerous advantages to using a dolly on a tow truck, there are also some drawbacks to consider.
- Limited Towing Capacity: Tow truck dollies have weight restrictions, and attempting to tow a vehicle that exceeds the dolly’s capacity can lead to equipment failure and unsafe towing conditions. When faced with towing larger or heavier vehicles, alternative towing methods may be necessary.
- Additional Equipment and Maintenance: Using a dolly on a tow truck requires additional equipment, such as ramps, straps, and holders. These components require regular maintenance and inspection to ensure they are in optimal working condition. Failure to properly maintain the dolly and its components can result in towing accidents or damage to vehicles.
- Increased Loading and Unloading Time: Using a dolly adds an extra step to the loading and unloading process. It takes time to position the vehicle on the dolly, secure it with straps or holders, and then repeat the process in reverse when unloading. This can increase the overall time required for each towing job compared to using a flatbed tow truck.
- Potential for Damage to Towed Vehicles: Improper loading, securing, or towing techniques can result in damage to the towed vehicle. Scratches, dents, or other forms of damage may occur if the vehicle is not properly aligned or if the straps or holders are not secured tightly. It is crucial to follow proper procedures and guidelines to prevent damage during towing.
Safety Considerations
Safety is paramount when operating a dolly on a tow truck. There are several key considerations to keep in mind to ensure the safety of the operators, the towed vehicles, and other road users.
- Proper Loading and Securing of Vehicles: It is essential to follow the manufacturer’s instructions and guidelines for loading and securing vehicles on the dolly. Failing to properly align the vehicle or secure it with straps or holders can result in damage or instability during towing. Double-checking the securement before towing is crucial.
- Routine Inspection and Maintenance: Regular inspection and maintenance of the dolly and its components are essential for safe operation. This includes checking the condition of the straps or holders, inspecting the main frame for any signs of wear or damage, and ensuring the hydraulic or electric controls are functioning correctly. Any issues should be addressed promptly to prevent accidents or equipment failure.
- Adherence to Traffic Laws and Regulations: When using a dolly on a tow truck, operators must adhere to all traffic laws and regulations. This includes properly signaling turns or lane changes, maintaining a safe distance from other vehicles, and obeying speed limits. Additionally, ensuring the dolly is equipped with the necessary lights and reflectors to comply with visibility requirements is crucial.

Towing companies and operators must ensure they are compliant with the necessary regulations and obtain any required licenses or permits. Failure to do so can lead to fines, penalties, or legal consequences.
