TOWING SAFETY INFORMATION
Gross Trailer Weight/ GTW
The Gross Trailer Weight is the weight of the trailer & çargo. Measure this by putting the fully loaded trailer on a vehicle scale.
Tongue Weight/ TW
The downward force that is exerted on the hitch ball by the coupler. The tongue weight will vary depending on where the load is positioned in relation to the trailer axle(s). To measure the tongue weight, use either a commercial scale or a bathroom scale with the coupler at towing height. When using a bathroom scale with heavier tongue weights, use the method shown and multiply the scale reading by 3.
Weight Carrying/NC
The total weight of both the trailer and the cargo inside. Never exceed the weight capacity of your trailer hitch.
Weight Distribution / WD
Used to balance the weight of the cargo between the front and rear wheels throughout the trailer, allowing for better steering, braking, and level riding.
Sway Control
A device used to reduce the lateral movements of the trailer that are caused by the wind. This works in conjunction with a weight distribution hitch. Do not use this on a class 1 or 2 hitches, or with urge brakes.
How Much Can You Safely Tow?
Ball Mount
The ball mount is placed inside the opening of the receiver hitch which is mounted to the vehicle. Make sure a hitch pin and clip is properly securing the ball mount to the receiver hitch before you begin towing.
- A: Rise.
- B: Drop.
- C: Hole Size.
- D: Length.
Trailer Ball
The connection from the hitch to the trailer. There are many tactors that determine the correct hitch ball: Number one is the hitch ball’s gross trailer weight rating The mounting platform must be at least 3/8 thick. The hole diameter must not be more than 1/16″ larger than the threaded shank.
Every time you tow, check the nut and lock washer to maké sure they are fastened securely.
- A: Ball Dia.
- B: Shank Length.
- C: Shank Dia.
- D: Shank Rise.
Coupler
The component that is placed over the trailer ball connects the vehicle to the trailer. Be sure that the coupler size matches the sizo of tho hitch ball and that the coupler handle is securely fastened. To determine what size hitch ball you need for your application you will need to know the size of coupler that is on the trailer. Be sure your coupler is properly adjusted to the ball you are using.
NOTE: For added sécurity the use of safety devices such as Coupler Safety Pins and Locks is strongly recommended.
Safety Chains
Safety chains are a requirement and should be crossed under the tongue of the trailer so that the tongue will not drop to the road if it becomes separated from the hitch. Always leave enough slack so you can turn. Nover allow the satety chains to drag on the ground and never attach the chains to the bumper
Trailer Classification: Safety Chain Breaking Force – Minimum
- Class 1: 2,000 lbs. (8.9 kN)
- Class 2: 3,500 Ibs. (15.6 kN
- Class 3: 5,000 Ibs. (22.2 kN)
The strength rating of each length of safety chain or its equivalent and its attachments shall be equal to or exceed in minimum breaking force the GVWR (Gross Vehicle Weight Rating) of the trailer.
Electrical
