The tow hitch has been a crucial component in the automotive industry, dating back to the early 20th century when the first cars began to replace horse-drawn carriages. It facilitated the transport of heavy loads and eventually evolved with advancements in vehicle technology.
Types of Tow Hitches
Receiver Hitch
A receiver hitch is mounted to the chassis of a vehicle. It includes a square receiver tube, allowing for different ball mounts and hitch accessories.
Fifth-Wheel Hitch
Commonly used for larger trailers, the fifth-wheel hitch is mounted in the bed of a pickup truck and provides a secure connection point in the center of the truck bed.
Gooseneck Hitch
Similar to the fifth-wheel hitch, but primarily used for towing livestock trailers and other commercial-grade trailers. It mounts directly over the rear axle of the truck.
Pintle Hitch
Often used in commercial and industrial applications, the pintle hitch allows for a greater range of motion and flexibility.
Bumper Hitch
A simple, lightweight hitch mounted on the rear bumper of a vehicle, suitable for towing light loads.
