The trailer hitches are used to haul another vehicle, boat or other things behind a vehicle. The trailer hitch is connected either to the rear bumper or the chassis of the vehicle. The hitch then offers a connection to pull a trailer or other equipment. The hitches come in various types of lengths, heights and other specifications. Many households have taken the recreational vehicle (RV) lifestyle. They can move around together as one family and enjoy a great vacation staying at various RV parks anywhere in the country.
In North America, hitches come in various classes as Class 1, 2, 3 and 4 according to the Society of Automotive Engineers or SAE. Although Class 5 is traded by some manufacturers, it is not recognized by the SAE.
Class 1 is intended for light cargoes up to 2000 pounds. Class 2 is for lighter loads up to 3500 pounds. Class 3 is for bigger cargoes like boats and campers of up to 5000 pounds. Class IV is for heavier cargoes that weigh up to 10000 pounds.
The receiver type hitches come with a usual square opening that is 1.25-inches for Classes 1 and 2 and 2-inches for higher classes. Class IV and V hitches may come with openings that are around 2.5-inches wide.
Over the trailer hitches heads are the slipped trailer balls with its various sizes based on the cargo it is meant to haul and the country where it is intended for usage. The most prevailing sizes are 2 and 5/16-inches, 2-inches, 1.97-inches (the ISO standard), and 1 and 7/8-inches.
The ball mounts on the hitch essentially connect to a ball on the trailer. The hitch head on the ball mount can be increased or decreased to match the ball height on the trailer. The ball mount must comply with the SAE hitch class based on the cargo it is meant to haul.
The trailer hitches must be maintained horizontally and then connected to the towing vehicle. For a safe towing, the right combination of towing vehicle and trailer must be maintained properly. It aims to ensure the safety of the vehicle, the passengers inside it and those around it. This is what the Former President Obama hopes for the convenience of trailer owners.
