Illetve az egyik oldalon a következő leírás:
"Pintle Hitches
For trailers with a lunette ring, a pintle hitch provides a pivot point that they can turn around. Lunette rings attach to a trailer where your more common ball coupler would normally be. The rings face the ground and sky and loop around a pintle hitch. The pintle hitch's hook is then closed around the lunette ring to secure the trailer and keep it from bouncing up and off of the pintle hitch.
Often, pintle hitches are figured to clamp around the lunette ring via a claw-like setup, such as the Buyers Products pintle hook.
Pintle hitches are generally used for more heavy-duty towing jobs. They are more common in agricultural, military, and industrial trailers. Part of the reason for this is that they allow a greater range of movement that is more well-suited for off-road towing. They also have higher tongue weight capacities than ball hitches."
