A bogie is a platform vehicle with a large array of wheels. It is used to transport large parts such as bridges, oil refinery equipment, as well as engines and other heavy objects that are too heavy for trucks.
What is a bogie?
A bogie is a type of trolley or cart floor that is similar to a back breaker, but the number of wheels is much more, which means that it has many axles, the number of which is proportional to the amount of load, and for carrying very heavy loads in order to reduce the load pressure on the road. The iron and the horse that pulls it are designed.
Division of bogies
- Road bogie
- Rail bogie
Road bogies are used to carry loads of 100 tons and above.
Specifications of bogies
- Height from the ground: 25±120 meters
- Number of wheels per axle: 8 wheels
- Tractors usually have 10 wheels, except for new tractors that have 12 wheels
Depending on the weight of the cargo, the number of these axles can be increased or decreased. That is, the heavier the load, the more the number of axles, usually the back breaking width of the bogie is chosen from three meters to three and a half meters depending on the width of the cargo. It is called becoming and it is added piece by piece and naturally the number of its killers will be more. In some cases where the load is heavy, four pullers are also used.
Carrying cargo by bogies requires special conditions. From road and road to traffic issues and drivers’ experiences and receipt of bill of lading, etc. It is interesting to know that the maximum speed of a bogie and its tractor with cargo is less than 30 km/h. Sometimes the work is so sensitive that the bogie driver has to move at 5 km/h.
The movement of a bogie requires special coordination with the country’s road police and road management organization, and sometimes with the Ministry of Oil and Energy. Buggies are only allowed to move from 6 am to 6 pm and they do not have the right to travel on the roads at night and on holidays.
Bogies and back breakers and similar devices must always move with two escorts, one in the back and the other in front of the cargo. In many roads of the country, as well as bridges that are not capable of carrying its weight and load, transport companies have to build side roads for the passage of bogies and tractors, which in turn leads to enormous costs. has it.
The bogie has non-constant loading and variable axles. In a bogie, the hydraulic power distribution system is used to transport extremely heavy and inseparable goods, which can carry any type of weight with the bogie machine due to the possibility of increasing and decreasing the axis.
The most important rules of carriage by bogie
Every country is subject to different laws and guidelines that the people of that country must obey those regulations in every area. As a cargo vehicle in the transportation industry, the bogie trolley is also required to follow the instructions and instructions that must be followed by its driver.
A skilled driver knows well what a bogie is and is familiar with all the rules of its operation. Just as in the road transport industry, car drivers etc. require compliance with guidelines, bogie truck drivers also operate in this field based on cases.
Some of the instructions for carrying a bogie are:
- The maximum speed of the bogie is less than 30 kilometers per hour, which sometimes even reaches 5 kilometers per hour. Currently, the type of truck and its towing vehicle can only travel on the main roads between 6:00 p.m. and 6:00 a.m., except on holidays.
- Due to the fact that many infrastructures do not have the ability to transport heavy loads, in order to pass heavy loads over the bridge, according to the prevailing laws and regulations, if the weight of the bogie car is more than 96 tons, it will be prohibited to cross the bridge. But this is in the case that if its weight was less than 96 tons, the tractor must first be moved to the other side of the bridge, and as a result, the cargo should be passed over the bridge by a tow wire at a maximum speed of 5 km per hour.
What are the restrictions for carrying cargo with a bogie?
We all know what a bogie is and as a special cargo vehicle it is capable of carrying very heavy loads. But the problem is not only the carrying of heavy loads by bogie trucks, but the road must also be able to bear such a weight.
If the road does not have the necessary resistance to bear the weight of the bogie, there may be many problems that are dangerous even for the citizens. For this purpose, in order to issue a traffic permit or electronic bill of lading, the Ministry of Roads must first check the cargo in terms of weight and dimensions, and after considering all aspects of the route, announce the route to the driver.
However, when the bogie moves, road construction and technical teams and escort also move along the route with the bogie to ensure safety. On the other hand, in order to carry such heavy cargoes, certain hours are considered for transportation; Because trolley bogies are not allowed to travel at all hours of the day and night.
What cargoes are transported with bogies?
This car usually carries very heavy loads. Usually bogies are also known as car transporters, which are used in Iran to transport heavy loads. This truck has the ability to increase or decrease its length, and it has such power that it can easily carry all kinds of very heavy loads.
Also, all the giant parts of different areas of the navy, air force, ground forces, etc., such as ships, power plant parts, large transformers, etc., are transported using bogies. But the very important thing about transporting cargo with bogie trucks is that when transporting cargo, the bogie truck must have an insurance policy and a smart bill of lading, so that in case of any accident or problem, damages can be paid.
