[Practical] Operational Guidelines for The Transportation of Bulky Cargo in Logistics (Part 1)

Bulky cargo transportation

For logistics, large items, as the name suggests, are items that have advantages in weight and volume. There are strict requirements for large items on transportation vehicles. They cannot be transported by ordinary transportation vehicles and require special transportation tools.

Oversized shipments include oversize and overweight.

Over-limit equipment (cargo) means that the loading outline size exceeds the vehicle limit standard; over-weight equipment (cargo) means that the effect of the total weight of the vehicle on the bridge exceeds the design live load.

Mainly include: generator stators, rotors, boiler drums, water walls, deaerated water tanks, high and low pressure heaters, large plate beams, etc. in large thermal power generation equipment; runners, upper and lower frames, and rotors in large hydropower equipment , stator, spindle, seat ring, water guide mechanism, gate hoist, main transformer, factory transformer, contact transformer, reactor, and high-voltage electrical equipment are all over-limit or overweight equipment.

(1) Overall dimensions of goods: goods with a length of more than 14 meters, a width of more than 3.5 meters, or a height of more than 3 meters;

(2) Single cargo weighing more than 20 tons or group (bundle) cargo that cannot be disassembled.

Large object classification

Large objects are divided into four levels according to their overall dimensions and weight (including packaging and supporting frames):

(1) First-class large objects refer to those that meet one of the following standards:

1. The length is greater than 14 meters (including 14 meters) and less than 20 meters;

⒉The width is greater than 3.5 meters (including 3.5 meters) and less than 4.5 meters;

⒊The height is greater than 3 meters (including 3 meters) and less than 3.8 meters;

⒋The weight is greater than 20 tons (including 20 tons) and less than 100 tons.

(2) Class II large objects refer to those that meet one of the following standards:

⒈The length is greater than 20 meters (including 20 meters) and less than 30 meters;

⒉The width is greater than 4.5 meters (including 4.5 meters) and less than 5.5 meters;

⒊The height is greater than 3.8 meters (including 3.8 meters) and less than 4.4 meters;

⒋The weight is greater than 100 tons (including 100 tons) and less than 200 tons.

(3) Level 3 large objects refer to those that meet one of the following standards:

⒊The height is greater than 4.4 meters (including 4.4 meters) and less than 5 meters;

⒋The weight is greater than 200 tons (including 200 tons) and less than 300 tons.

(4) Level 4 large objects refer to those that meet one of the following standards:

⒈The length is 40 meters and above;
