STARTING AND OPERATING 413 Tongue Weight (TW) The tongue weight is the downward force exerted on the hitch ball by the trailer. You must consider this as part of the load on your vehicle. The frontal area is the maximum height multiplied by the maximum width of the front of a trailer. The trailer sway control can be a mechanical telescoping link that can be installed between the hitch receiver and the trailer tongue that typically provides adjustable friction asso- ciated with the telescoping motion to dampen any unwanted trailer swaying motions while traveling. nizes a swaying trailer and automatically applies individual wheel brakes and/or reduces engine power to attempt to eliminate the trailer sway. Weight-Carrying Hitch A weight-carrying hitch supports the trailer tongue weight, just as if it were luggage located at a hitch ball or some other connecting point of the vehicle. These kinds of hitches are the most popular on the market today and they are commonly used to tow small and medium sized trailers. A weight-distributing system works by applying leverage through spring (load) bars. They are typically used for heavier loads to distribute trailer tongue weight to the tow vehicle's front axle and the trailer axle(s). When used in accordance with the manufacturer's directions, it provides for a more level ride, offering more consistent steering and brake control, thereby enhancing towing safety. The addi- tion of a friction/hydraulic sway control also dampens sway caused by traffic and crosswinds and contributes positively to tow vehicle and trailer stability. Trailer sway control and a weight distributing (load equalizing) hitch are recom- mended for heavier Tongue Weights (TW) and may be required depending on vehicle and trailer configuration/ loading to comply with GAWR requirements. 5 |
