For decades, towing professionals have trusted Collins Manufacturing for reliable, innovative dollies that get the job done—especially when working in tight, high-pressure situations. Now, we’re proud to introduce our most advanced model yet: the G7 Hi-Speed® Dolly. As our seventh-generation dolly since 1972, the G7 represents everything we’ve learned through years of real-world experience and direct collaboration with the people who use our equipment every day. Built with input from industry experts, the G7 blends comfort, strength, and high-speed performance to help you work faster, safer, and more efficiently—without sacrificing the durability you’ve come to expect from Collins.
7 Incredible Features of the New G7 Hi-Speed® Dolly
The G7 Hi-Speed® Dolly is the most advanced dolly Collins has ever engineered—and the upgrades are more than just cosmetic. Every feature was thoughtfully designed to make your job easier, safer, and more efficient. Here’s what sets the G7 apart:
1. Integrated Spindle and Trip-Lock Assembly Bolts
The redesigned assembly now rotates as a single unit, preventing bolts from loosening or backing out over time. That means less hassle on the road and more confidence in your equipment.
2. “Walk the Dolly” Innovation
Tight on space? No problem. A newly engineered pry pocket on the spindle assembly allows operators to walk the dolly forward, rather than carry it—reducing physical strain and improving maneuverability in confined areas.
3. Cambered Cross Rails for a Wider Fit
Choose from 3-piece 90” T10 or ultra-wide 104” T12 cross rails to accommodate today’s larger vehicles, trailers, and dually trucks. The center camber design improves fit and function across the board.
4. Ergonomic Motorcycle-Style Handle
The G7 features a rubberized, motorcycle-style handle that offers a more natural grip, better control, and greater comfort—especially during long or repetitive use.
5. Low-Maintenance, High-Efficiency Design
Self-lubricating, fully enclosed bushings eliminate the need for messy grease and frequent maintenance. Spend less time maintaining and more time towing.
6. Advanced Safety Ratchet System
Built with a carbon-fiber filament injection-molded ratchet cam, the G7 resists corrosion, withstands harsh elements, and keeps components moving smoothly and reliably.
7. Precision-Machined G7 Dolly Spindles
Crafted in-house from a single piece of high-strength material, these CNC-machined spindles increase structural integrity, minimize misalignment, and help extend both tire and bearing life.
Real-World Advantage: When Tight Spaces and Time Matter
Picture this: A vehicle is illegally parked in a narrow alleyway behind a busy urban apartment complex. The car is wedged tightly between a brick wall and a dumpster enclosure, leaving minimal clearance for maneuvering a tow truck. Access is further complicated by limited lighting and uneven pavement—conditions that can quickly escalate frustration and risk for towing professionals.
With traditional dollies, the operator might have to physically lift and carry the dolly into place, risking injury or fatigue, especially if done repeatedly on calls like this. Aligning the dolly under the vehicle can be cumbersome, especially without a precise fit or easy mobility in a confined space.
Now imagine the same job with the G7 Hi-Speed® Dolly.
Instead of lifting, the operator uses the redesigned “Walk the Dolly” feature to slide it into position easily, using the pry pocket to guide it smoothly through the tight alley. The wider cambered cross rails perfectly accommodate the vehicle’s width, whether it’s a compact SUV or a dual-wheeled pickup. Once the dolly is in place, the ergonomic handle makes adjustments intuitive and fatigue-free.
Thanks to the self-lubricating bushings, setup is quick and mess-free—even in poor lighting. The carbon-fiber safety ratchet system secures the load fast, and the precision-machined spindles ensure smooth towing without added wear on the tires or bearings, even across bumpy surfaces.
Result: A high-stress situation becomes routine. The operator works more quickly, more comfortably, and with far less risk—all because of the engineering behind the G7 Hi-Speed® Dolly.
