The most common type consists of three parts, one part on the body of the cubicle, one part on the door, and the third being the pintle. In transportation, a pintle hitch is a type of tow hitch that uses a tow ring configuration to secure to a hook or a ball combination for the purpose of towing an unpowered vehicle. [1] [2]
A pintle hook and lunette ring make a more secure coupling, desirable on rough terrain, compared to ball-type trailer hitches. It is commonly seen in towing applications in agriculture, industry, and the military. [citation needed] The clearance between the lunette and pintle allows for more relative motion between the trailer and tow vehicle ...
Other familiar forms are the tractor-trailer combination, and cargo or leisure vehicles coupled via ball or pintle and gudgeon trailer hitches to smaller trucks and cars. In the opposite extreme are extremely heavy duty tank recovery vehicles , and enormous ballast tractors involved in heavy hauling towing loads stretching into the millions of ...
The field artillery limber assumed its archetypal form – two wheels, an ammunition chest, a pintle hook at the rear, and a central pole with horses harnessed on either side. The artillery piece had an iron ring at the end of the trail. To move the piece, the lunette was dropped over the pintle hook (which resembles a modern trailer hitch).
In addition to the wrecking body, all trucks had a 20,000 lb (9,100 kg) front winch and a rear pintle hitch. Not intended to carry a load, the M1 could support 8,000 lb (3,600 kg) while towing up to 60,000 lb (27,000 kg). [ 8 ]
They received CARC exterior paint (Forest Green, Desert Sand, or 3-color camouflage), a brush bar, a pintle hitch, towing/loading shackles, extra leaf springs to give them a 5/4 ton rating and a host of other small changes. All CUCV IIs have a 24 volt dual-battery starting system, the rest of the truck is 12 volt.
They had a pintle hitch at the rear for towing up to 40,000 lb (18,000 kg). Another pintle at the front could be used to emplace the piece. A mid-mounted 25,000 lb (11,000 kg) winch had a centered cable drum and a capstan on the right side. Pulleys and rollers routed the cable under the body and out the rear frame cross-member.
Without a fifth wheel, the modern distribution system would look quite different as drop-and-hook would not be easy. The semi-trailer increased the capacity of trucks, but it was the fifth wheel that brought the flexibility for drivers to keep moving while receivers unloaded the loads they just delivered.
