How to Do Trailer Hitches Work?
The working principle of a trailer hitch is not complicated. It holds the trailer securely to the vehicle using a sturdy attachment. When the vehicle moves, the trailer hitch ensures that the trailer moves in sync, providing stability and security. A trailer hitch can play an important role when you are towing a boat, caravan, or cargo.
The components of a trailer hitch are the ball head, pin, and tow bar. The ball head provides a flexible swivel that can accommodate different angles. The pin ensures that the connection is secure and less likely to fall off. The tow bar transmits the force to the trailer. Several parts coordinate with each other to help the user to complete the towing work.
How Are Trailer Hitches Classified?
Understanding trailer hitches' classification is key to picking the right one. Below are ways to categorize trailer hitches according to different dimensions to help you find the best one for your needs.
1. Classification of trailer hitches according to their load-bearing capacity
Depending on the weight capacity of the trailer hitch, they can be classified into the following five classes:
Class I: Maximum towing capacity is 2,000 pounds and is suitable for compact cars and small SUVs.
Class II: The maximum towing capacity is increased to 3,500 lbs, also for light cars and small SUVs.
Class III: Load capacity up to 8,000 lbs. With a 2-inch receiver, this is the most common type of hitch found on pickup trucks and SUVs.
Class IV: Supports up to 10,000 lbs. and is primarily used on full-size pickups and SUVs with a 2‘ x 2’ receiver.
Class V: Heavy-duty hitch that supports up to 20,000 lbs. Receiver size is 2‘ or 2-1/2’ for more demanding towing duties.
2. By receiver size
The size of a trailer hitch receiver determines its versatility and adaptability. The four common standard sizes are:
- 1-1/4 in.
- 2 in.
- 2-1/2 in.
- 3 inch
1-1/4‘ is found on Class I and II hooks for light loads, 2’ is standard on Class III and IV hooks and is the most commonly used size and 2-1/2‘ and 3’ are primarily used on heavy-duty Class V hooks for larger loads.
