The intention of a trailer coupler is to secure the trailer to the towing vehicle. It is an important piece, as the trailer couple attaches to the trailer ball. This then forms a ball and socket connection.It allows for relative movement between the towing vehicle and trailer while towing over uneven road surfaces. The trailer ball shouldbe mountedto the rear bumper or to a drawbar, which may be removable. The drawbar secures to the trailer hitch by inserting it into the hitch receiver and pinning it.
The three most common types of couplers used are straight couplers, A-frame couplers, and adjustable couplers.Another option is bumper-pull hitches in which case draw bars can exert a large amount of leverage on the tow vehicle.This makes it harder to recover from a swerving situation (thus it may not be the safest choice depending on your trip).
The United States Department of Transportation has become a fundamental necessity in the moving industry.It is the pinnacle of the industry, creating and enforcing regulations for the sake of safety for both businesses and consumers alike.However, it is notable to appreciate the history of such a powerful department.The functions currently performed by the DOT were once enforced by the Secretary of Commerce for Transportation.In 1965, Najeeb Halaby, administrator of the Federal Aviation Adminstration (FAA), had an excellent suggestion.He spoke to the current President Lyndon B. Johnson, advising that transportationbe elevatedto a cabinet level position. He continued, suggesting that the FAAbe foldedor merged, if you will, into the DOT.Clearly, the President took to Halaby's fresh ideasregardingtransportation, thus putting the DOT into place.
Full truckload carriersnormallydeliver a semi-trailer to a shipper who will fill the trailer with freight for one destination.Once the traileris filled, the driver returns to the shipper to collect the required paperwork.Upon receiving the paperwork the driver will then leave with the trailer containing freight. Next, the driver will proceed to the consignee and deliver the freight him or herself. At times, a driver will transfer the trailer to another driver who will drive the freight the rest of the way.Full Truckload service (FTL) transit times are generally restricted by the driver's availability. This is according to Hours of Service regulations and distance.It istypicallyaccepted that Full Truckload carriers will transport freight at an average rate of 47 miles per hour. This includes traffic jams, queues at intersections, other factors that influence transit time.
