Types of Semi Trailers

Tankers are used to transport liquids and fuels. Tankers are used to transport milk and similar dairy products. Before moving this kind of merchandise, there are certain cleanliness and refrigeration requirements. It is important to maintain this semi-trailer. Tanker trailers are also used to transport fuel. They usually ship fuel to truck stops or gas stations. Because of shifting liquids, tanker trailers are more difficult to drive. Before embarking, the driver must be familiar with how to safely drive them.

Flatbed trailers, a popular type of semi-trailer, are very versatile. These trailers can haul heavy equipment, machinery and construction materials. A crane can be used to load the merchandise from the sides, top or rear. The driver must be familiar with how to transport the merchandise safely. They should also know what protections are required. Protecting equipment can be made easier by using tarps. It can be difficult to load, unload and secure the equipment.

Another popular semi-trailer type is the van semi trailer. It can transport all types of merchandise. The compartment can be equipped with a cooling unit that will allow it to transport perishable goods. The majority of van trailers have rear loading doors. To fill the container, you will need to use a forklift. Side doors are available on some van trailers to make loading easier. Usually, food orders will be shipped to supermarkets and warehouses.

People outside the trucking industry often ask: "How does a road tractor connect to a semi-trailer?" Two connecting devices are used to attach these pieces of transport equipment. The "fifth" wheel is located on the rear frame. The "kingpin", located at the truck trailer's front end, is the other. This is a quick explanation.

What's a Fifth-Wheel, you ask?

A fifth wheel was originally a steering mechanism that resembled a wheel that allowed the front axle of horse-drawn wagons to turn when turning. John C. Endebrock invents a system to attach trailers to motor cars around 1910. The first trailers were pulled by Ford Model "T" passenger cars. To attach the trailer to the car, three men were required. Endebrock created a new coupling device that allowed one driver to connect the tractor and trailer in 1918. The fifth wheel's new design featured a jaw that had a spring locking device attached to it.

Six Simple Tips to Finance a Semi-Trailer Truck

The fifth wheel is a coupling device that connects a road tractor and semi-trailer. A fifth wheel is made of heavy metal and has a slot in the center. It attaches horizontally to the chassis, above the rear axles of a road tractor. It is located at the rear, and contains a locking device. Endebrock's early 20th century design for the fifth wheel is very similar to today's.

What's a Kingpin?

The kingpin, a cylindrical heavy-metal pin located under the trailer's front end, is called a kingpin. The trailer's locking mechanism, the kingpin, is what locks it to a tractor. The kingpin is usually located between 18" and 48" from the trailer nose. The kingpin is surrounded by a greased metal grid plate. This grid plate allows fifth wheel to slide under the trailer. The fifth wheel pivots underneath the trailer's grid plates when the tractor is backed into a trailer's nose. The fifth wheel locks onto the trailer's pin.

The fifth wheel, when coupled to the kingpin allows the semi trailer's to turn at the point where the fifth wheels and kingpin meet. This rotating attachment allows tractor-trailer combinations to turn and gives them stability and maneuverability. After the load has been delivered, the driver will disconnect the tractor from the trailer and roll down the dolly legs of the trailer. The driver then pulls a lever that disengages the fifth wheel locking mechanism, and the tractor is driven away. Get more info
