Towing is simply coupling two or more moving objects together so they can be towed by a given towed object or systems. The towing mechanism may be a powered vehicle, boat, animal, or person, and usually the load being towed is anything which can be towed. towed are also commonly known as unloading or dockings. Towing a trailer or other objects requires an act of tow, pulling them with a tractor, truck, car or other vehicle, and finally balancing them on a fixed structure.
Towing of course is not as simple as tying a rope around something and pulling it along with the trailer. Towing is usually done in the following way: first, the objects are located where they should be, usually on the ground or the shore. Then, a towing device is attached to the vehicle, either by mechanical, hydraulic, or mechanical-mechanical systems. Then, either a tug or a forklift is used to pull the trailer.
There are three basic types of towing: straight, parallel and semi-permanent. For a straight tow, the towing vehicle is behind the trailer. On the other hand, a straight tow is when something is towed directly behind another, usually an aircraft type vehicle. Parallel towing is when a towing vehicle is behind the trailer of something which is in motion, such as a boat or a truck.
Then, there is the semi-permanent towing method, which is the most widely used. Semi-permanent towing is when the towing vehicle is behind the trailing vehicle, on the same side, with a gear in between the two. If the vehicle being towed moves erratically, the tug can be used to stop the towing vehicle, to prevent further damage to the trailer or the truck. A nose landing gear is used for this, but on smaller vehicles the gearbox will not have the power needed to complete the towing operation.
The third and final way that a towing capacity is calculated is based on the weight and GVA of the trailer alone, while subtracting the weight of the towing vehicle. This gives a final number for the towing capacity. The weight and GVA of the trailer and of the towing vehicle must be correct for the weight and GVA of the trailer to be calculated properly. Otherwise, the calculation will be off. A vehicle manufacturer’s website will usually list the trailer’s weight and the gross weight of the towing vehicle.
Towing of special trailers can be very dangerous if not done properly. For example, the weight of a tractor-trailer alone is often more than the trailer’s weight plus its frame, which make the towing experience dangerous, even when properly planned. These specialized trailers must also be designed to handle the extra physical work, such as towing long distances without any luck, etc. A combination of factors, such as towing capacity and towing load, will determine the cost of towing a trailer. A simple calculation of GVA and weight of the trailer alone can be misleading.
