Modern fifth wheels allow the trailers to slide into the fifth wheel and lock into it very reliably when maintained and serviced properly. The engagement of the king pin into the fifth-wheel locking mechanism is the only means of connection between tractor and trailer; no other device or safety mechanism is used.
The gooseneck hitch mounts in the middle of the truck bed. This hitch is designed to be paired with a gooseneck trailer, which can manage heavier loads than a hitch at the back of the tow vehicle. An advantage of the gooseneck hitch is its tighter turning radius, which helps when towing a big flatbed or car hauler.
The couplers automatically lock when cars are pushed together, but workers must go between cars to hook up the air lines for the pneumatic brakes and connect cables for head-end power and other communications. To separate cars, a worker must use a lever to move the locking pin that keeps the coupler closed.
Quick couplers (also called quick hitches) are used with construction machines to allow the rapid change of working tools or buckets and attachments on the machine. They remove the need to use hammers to manually drive out and insert the mounting pins for attachments.
Two or more passenger or freight cars may be attached by means of a drawbar rather than a coupler. At each end of the permanently coupled vehicles there is a regular coupler, such as the North American Janney coupler or the Russian SA3 coupler. The use of a drawbar eliminates slack action.
