Revealing The Entire Manufacturing Process of Cranes From Steel Plates To Finished Products

Have you ever wondered how cranes are made? Let's witness together the transformation journey of a standard crane from raw materials to finished products.

Phase One: Raw material Preparation (Accuracy starts from ±1mm)

Cutting accuracy: ±0.5mm (equivalent to the diameter of three human hairs)

Dust removal system: 98.7% of the metal dust is recycled and reused

First inspection system: Each batch of steel plates must undergo ultrasonic flaw detection

"This seemingly ordinary steel plate will withstand a tensile force of 80 tons in the future without deforming," said Master Wang, a quality inspector

Phase Two: Structural Component Manufacturing (Robot-led Welding Revolution)

In the welding workshop where sparks are flying, six KUKA robots are working in coordination:

Boom welding: Continuous welding for 48 hours without interruption, with a cumulative weld length of 320 meters

Tower section ring welding: Submerged arc welding process is adopted, with a penetration depth of 12mm

Real-time monitoring: The infrared thermal imager ensures that the welding temperature is always maintained at 1200±50℃

Key equipment:

2000-ton hydraulic bending machine (capable of precisely controlling the bending Angle to 0.1°)

Plasma cutting platform (cutting speed up to 8m/min)

Phase Three: Final Assembly and Commissioning (200% Rigorous testing)

On the final assembly line, the workers are undergoing the final "physical examination" :

Security test checklist:

Overload test: Rated load 50 tons, actually loaded to 100 tons and maintained for 1 hour

Fatigue test: Simulate 2,000 cycles of continuous operation (equivalent to 5 years of usage intensity)

Extreme environment test: Alternating tests in a -40℃ cold storage and a 50℃ high-temperature chamber

The new regulations in 2023 stipulate that all welds must undergo industrial CT scanning with a detection accuracy of 0.02mm

Phase Four: Intelligent Upgrade (Equipping Steel with a "Brain")

Modern cranes are no longer simple steel structures:

Black box system: Records operating parameters and can trace all operations within 10 years

Predictive maintenance: Detect potential faults three weeks in advance through vibration sensors

5G remote control: Engineers can debug any device in the world from the office
