How Do Cranes "pack And Travel" : A Complete Revelation of Large Equipment Boxing And Shipping

When you see the towering cranes at the port, have you ever wondered how these "steel giants" crossed the ocean to the construction site? Today, we are going to reveal the wonderful journey of cranes from the factory to the installation site.

I. Disintegration and Division: The art of breaking down the whole into parts

The principle of modular decomposition

It is functionally divided into core modules such as the base, slewing mechanism, boom, counterweight, and cab

Typical split data:

An 80-ton crane can be decomposed into 15 to 20 transportation units

The maximum weight of a single piece is usually controlled within 40 tons (meeting the restrictions of road transportation).

Precision disassembly process

The disconnection sequence of electrical disconnection first and then mechanical disconnection

The key connection parts are marked with laser positioning

Professional sealing of hydraulic systems (to prevent oil leakage)

Ii. Packaging Protection: Put "protective clothing" on steel

Customized packaging solution

Precision components: Vacuum anti-rust packaging + wooden case

Structural components: Waterproof canvas + steel frame fixation

Vulnerable parts: Foam plastic + honeycomb cardboard buffer

Special treatment technology

Spray VCI vapor phase anti-rust agent on the metal surface

The electronic components are equipped with desiccants and humidity indicator cards

The moving parts adopt special fixed brackets

Iii. Loading and Transportation: A Relay Race by sea, land and air

Typical combination of multimodal transport

Factory area → Port: Hydraulic axle line vehicle (with a load capacity of up to 500 tons)

Transoceanic transportation: Specialized heavy crane vessels (equipped with 2,000-ton cranes)

Final mileage: Modular trailer group (flexible combination available)

Key loading technologies

The three-dimensional center of gravity calculation software ensures stability

Special twist lock fixing device (Wind and wave resistance grade 12)

Real-time GPS+ temperature and humidity monitoring system

Iv. On-site Revival: The Transformation from Parts to Giants

Professional assembly process

Basic acceptance → Main body hoisting → system connection → commissioning and testing

Typical assembly cycle: 7 to 15 days for medium and small-sized cranes

Precision guarantee measures

Laser alignment instrument (Installation accuracy ±0.1mm/m)

Vacuum oil injection technology for hydraulic systems

72-hour continuous load test

When the next crane passes by you, please remember the round-the-world journey it has experienced. Modern logistics technology enables these ten-thousand-ton steel giants to be safely dismantled and transported to all parts of the world just like Lego bricks.
