Trailers designed to carry heavy loads are increasingly being used at many different construction sites all over the country. They trailer itself is not motored but is attached to a vehicle that powers the entire equipment and carries that trailer. The trailer itself is a flat floor which is supposed to carry a heavy load on it. It must be strong enough to bear that heavy burden. They often carry machine parts or entire machines in order to transport them from one place to another. All trailers, like gooseneck trailers, for example, are built a little differently. Each trailerís design serves to enhance its purpose.
Some trailers may also have bunks while others like water hauler trailers
, have a huge tube-like container used to store and transport liquids (water and/ or oil, for example). Trailers with two bunks allow each bed to drop down so that cars are driven on top of the trailer (and off them too, of course). Some trailers come with ramps that may be attached to and controlled by the vehicle or ones that need to be attached to the vehicle manually, with the aid of workers. In order to hold the cars in place, there are belts or straps tied around the car. Sometimes, there are also devices used to stop the wheels of the vehicle from rotating.
Some trailers lift the thing to be transported in the air so that it can be placed on the bunk of the trailer. For example, dump trailers
often come with devices used specifically to grab the trash and haul it on to the dumpster attached to the motored vehicle. Other trailers will place their bunk on the ground so that the thing to be transported can easily be moved on to it. Winches are used to make the transition easier and quicker for the workers. Since so much is hauled on to the trailer, it must be made of strong steel to ensure its own longevity.
Many heavy equipment trailers, like gooseneck trailers, have some axels fixed in them. 4 x 4wheels are used too, with the axels, to make sure the trailer has the required strength to carry the heavy loads it has been tasked to transport. Such wheels are big in size and are constructed for powerful grip to reduce the damage that may be inflicted on the equipment being transported. Of course, one may not need that with dump trailers. The width of the axels will depend largely on the width of the bunk of the trailer. Each axel tends to have five or more wheels so that the trailer remains as steady as possible during the journey.
As the name conveys, water hauler trailers are used to transport huge gallons of water from one place to another in as short a time as is possible, logically. These trailers are commonly used in construction sites and to manually fill up water tanks when there is a problem with the pipes. These trailers often transport water to areas stricken with drought, places with little water supply and to fill up swimming pools and the like.
