Stehl Tow Dollies are the strongest most heavy duty tow dollies on the market today. The biggest advantages to the Stehl tow dolly include: an axel weight rating of 3500lbs., 7000lb rated lashing winches, 6000lbs rated tires and the maintenance free steel frame with 80 inches of clearance between fenders. These dollies also feature a lockable coupler designed to fit any standard 2 inch ball. What are Hydraulic Surge Brakes? Hydraulic surge brakes are a totally self-contained tow dolly braking system, requiring no electrical, hydraulic or other connection of brake sensing components to the tow vehicle for automatic operation of the tow dolly brakes. In a hydraulic surge brake system, the inertial differential pressure developed between the tow vehicle and the tow dolly, during the braking process, creates a mechanical pressure which is applied to the push rod of the master cylinder in the hydraulic surge brake coupler. This mechanical pressure is proportional to the difference in pressure between the two vehicles and therefore, the hydraulic output of the brake coupler, and resulting brake operation, is automatic, regulated, and proportional to the amount of braking being applied to the tow vehicle.
