Coke Pot Crane for CDQ: Exceptional Heavy-Duty Red-Hot Coke Handling

The coke pot crane, also known as the CDQ bucket-hoisting crane, is a core handling system in the Coke Dry Quenching (CDQ) process. It is responsible for lifting red-hot coke (up to 1000°C), transferring the coke bucket, and charging the material accurately into the CDQ cooling chamber. The crane operates under extremely high radiant heat, continuous heavy-duty cycles, and requires high reliability, precision positioning, and automation levels.

• Rated lifting capacity: 50–140 t
• Working duty: A8 
• Lifting height: 30–50 m

Working Environment

The CDQ coke pot crane is engineered for extreme industrial conditions, including:

• Ambient temperature: –20°C to +40°C
• Intense radiant heat from red-hot coke (up to 1000°C)
• 24/7 continuous operation
• Precise charging requirements for CDQ throat alignment

Key Features

• Rigid guiding frame structure: Ensures fast, stable, and accurate bucket lifting even under extreme radiant heat conditions.
• Full-automatic operation with preset motion curves: Guarantees consistent cycle time, stable production rhythm, and improved CDQ thermal efficiency.
• Inverter-controlled hoisting & traveling mechanisms: Reduce dynamic impact, enhance smoothness, and improve positioning precision.
• High precision positioning: Hoisting accuracy ±45 mm, traveling accuracy ±20 mm. Vital for safe, efficient charging into the narrow CDQ furnace opening.
• Automatic precision positioning & wireless video monitoring: Enhances human–machine interaction and significantly improves operational efficiency.
• Centralized electrical control with mechanical anti-sway: Ensures smooth and stable operation of the coke pot crane.
• Full-lifecycle crane management platform: Enables real-time condition monitoring, operational data logging, fault alarm tracking, and remote diagnostics/commissioning.
• Designed for harsh coking plant environments: Fully considers high temperature, radiation, dust, and corrosive gases, ensuring reliable performance and meeting all CDQ process requirements.
