You're In Good Hands
We've designed a more comfortable and ergonomic handle for our product. It feels like a motorcycle or bike handle for a reason; it is one. Our handle design allows for a better grip and carry, making your experience using our product more enjoyable and efficient. With its improved ergonomics and feel, you'll be able to use our product for extended periods of time with less strain on your hands. Experience for yourself why the Collins Hi-Speed® Line remains unrivaled as the Towers Choice™ dolly.
The Low Maintenance Dolly
No more grease - The Collins Hi-Speed® G7 Dolly is designed for minimal maintenance, making it a practical choice for operators on the road. Its self-lubricating, fully enclosed bushings and zinc-plating finish provide superior corrosion protection and durability. These features keep the dolly in top condition, even in harsh environments and heavy use. To ensure optimal performance and longevity, we recommend regularly washing the dolly.
More is Less
The Collins Hi-Speed® G7 Dolly offers more features while remaining lightweight. Its safety features reduce the risk of injury, its freeway approval and long-distance rating provide greater capability, and its high capacity allows for less physical effort. This results in more time spent serving customers and making money, as only one tow truck and driver are needed instead of using less capable equipment that requires two trucks and drivers.
The Walkable Dolly
Get ready to revolutionize the way you tow! We've listened to your valued feedback and heard your plea for a more operator-friendly dolly. In addition to the more comfortable handle, our Collins Hi-Speed® G7 Dolly has a redesigned pry pocket with a slot to insert the pry bar allowing you to "walk" the dolly. This helps in tight spaces and makes it easier for the operator to transport the dolly.
Composites For Harsh Weather
The Collins Hi-Speed® G7 Dolly is designed for tow operators working through extreme weather conditions. With its weather-resistant design, it can withstand even the toughest conditions ensuring maximum durability and reliability. The Collins Hi-Speed® line of dollies are also THE ONLY freeway-approved dollies, making it the Towers Choice™ for operators.
Positive Transformations
A new, wider cross rail axle with improved true-positive camber and strengthened aluminum tubing. Available in two versions-T10 & T12, with the T12 extending wide enough for dually pickups, utility and boat trailers. We beat our own records so you can have record-breaking performance.
When it Matters, Choose Collins.
