What is towing?
Towing, in its basic sense, means to aid the movement of other vehicles by pulling it. This can be done with automobiles on road, cargo in rivers, aircrafts and gliders. The names of vehicles involved in towing are different for different means of transport. However, they can be, in general, called “tractor-trailer vehicles”.
The key factors for successful towing is the power generated by towing trucks and the type of joint between tower and trailer vehicles.
Towing capacity of a vehicle depends upon the power generated by that vehicle. Hence choice of vehicle is made based upon the trailer load and means of transport.
For roadways it can be either another car or towing truck or a tractor. Usually this is done for wrecked or damaged vehicles or due to violation of Government regulations or parking tickets. For aircrafts, it can be other aircrafts or towing trucks. This is primarily used to power other damaged aircrafts or for pushback from dock to taxiway. Tug boats are used these days to haul cargo on rivers. However tug boats aren’t used for too long distances, usually not as long as hundreds of nautical miles, as it might minimize the efficiency of transport.
The joint between tractor and trailer is important that it needs to sustain extreme tensions while pulling is done. There are many tools and methods employed. Depending upon the heaviness of the vehicle anything ranging from rope, chain, hitches, drawbar, fifth wheel are used.
It’s the combination of instruments used and vehicles used along with practical knowledge of this process make towing an efficient task.
