Hydraulic modular trailer, a special platform trailer unit which feature swing axles, hydraulic suspension, independently steerable axles, two or more axle rows, compatible to join two or more units longitudinally and laterally and uses power pack unit to steer and adjust height.Unpowered train cars pulled behind a locomotive can also be considered in this category. Trailers for speciality applications that may require a specialized vehicle, such as a farm tractor military truck, tank, or personnel carrier or an unusually large semi-truck.Non-containerized tractor-trailer boxes are also fairly common, and work much like containers, above, but frequently with the stand and dolly integrated permanently into the box.The containers are also stacked on ships and used as railroad boxcars. Container trailers are standard intermodal "boxes" that can be fitted with a dolly (wheel truck) and front stand they can then be used in a standard tractor-trailer combination.Tank trailers, which are trailers designed to contain liquids such as milk, water or motor fuel.Some are small enough to be towed behind cars. This type of trailer works well for hauling large or unconventional shaped objects. Roll trailer, Flat bed or open trailers, which are platforms with no sides or stakes.Trailers designed to be hauled in an 18-wheel tractor-trailer configuration, which come in many configurations:.In the United Kingdom, RV trailers are known as caravans. These trailer hitches are common on the back of many cars and trucks, and RV trailers are commonly used for camping outings or road trips. While some are self-propelled (integrated truck chassis), many are designed as trailers to be attached to a trailer hitch. Recreational vehicles (RV) are utility vehicles or vans that are often equipped with living facilities.They are open trailers that are specially-shaped to hold and secure boats because of this specialty, they are a unique category.
These types of trailers are designed for easy loading in and out of the water and are purchased based on the specific type and style of boat they will be hauling.
This section refers to the towing of a cargo-carrying device behind a truck or car. Troop and cargo-carrying gliders are towed behind powered aircraft, which remains a popular means of getting modern leisure gliders aloft. Over thousands of years the maritime field has refined towing to a science.Īircraft can tow other aircraft as well. Today, tug boats are used to maneuver larger vessels and barges. Historically, barges were hauled along rivers or canals using tow ropes drawn by men or draught animals walking along towpaths on the banks. Necessarily, government and towing sector standards have been developed for carriers, lighting, and coupling to ensure safety and interoperability of towing equipment. 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 pounds. 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. The most familiar form is the transport of disabled or otherwise indisposed vehicles by a tow truck or "wrecker". Towing may be as simple as a tractor pulling a tree stump. These may be joined by a chain, rope, bar, hitch, three-point, fifth wheel, coupling, drawbar, integrated platform, or other means of keeping the objects together while in motion. The towing source may be a motorized land vehicle, vessel, animal, or human, and the load being anything that can be pulled. Towing is coupling two or more objects together so that they may be pulled by a designated power source or sources.
