Intelligent Grab Bucket Overhead Crane Featured Engineering Cases

Case 1: Guangxi Chiyi Steel – 2060 m³ Blast Furnace Project

Our company manufactured 59 sets of various high-quality cranes for Guangxi Chiyi Steel Co., Ltd. Among them, four 32-ton intelligent grab bucket overhead cranes were applied to the company's 2060 m³ blast furnace project, providing intelligent equipment support for industrial transformation and upgrading.

Technical Advantages:

• Custom-designed to adapt to complex operating conditions such as high temperature, high humidity, and heavy fog
• Equipped with intelligent integrated systems, including PLC control, positioning systems, and anti-sway control
• Heavy-duty wide-box structural design with high fatigue resistance
• Capable of automatic grabbing, placing, and transferring materials in low-visibility environments
• Supports remote dispatch and management systems, eliminating the need for on-site operation
• Significantly reduces labor intensity for operators

Case 2: Baowu Shaoguan Steel – 250,000-Ton Rotary Hearth Furnace Project 

Two unmanned intelligent grab bucket overhead cranes were manufactured for the 250,000-ton rotary hearth furnace project at Baowu Group Shaoguan Steel. The cranes were custom-developed in accordance with Shaoguan Steel's intelligent manufacturing strategy and rotary hearth furnace steelmaking process, providing strong support for achieving true “one-click steelmaking” across the entire system.

Key Highlights:

• 5 mm precision positioning: three-dimensional scanning, automatic positioning, obstacle avoidance, recognition, and grabbing
• Unmanned operation: operators can control the crane from an office 1,000 meters away
• Since commissioning, labor intensity has been significantly reduced and the operation has remained stable
• The unmanned operation level has reached a leading standard in China
• Jointly established inspection and testing standards with the China Academy of Machinery Science & Technology, setting benchmarks for the industry

Case 3: Waste-to-Energy Project – Automatic Grab Bucket Overhead Crane

KUANGSHAN CRANE developed and manufactured an automatic intelligent grab bucket overhead crane for a waste-to-energy power generation project, which has been successfully put into operation. With features such as automatic fixed-point grabbing and constant-weight cyclic operation, the crane has gained widespread recognition as another innovative intelligent product.

Main Technical Advantages:

• Full variable-frequency drive system combined with absolute encoders for millimeter-level position control
• Three control modes: manual control, wireless remote control, and automatic fixed-point unloading; fully automatic interfaces are reserved for future capacity upgrades and process adjustments
• Integrated anti-sway control, automatic fixed-point grabbing, and constant-weight cyclic operation, forming a closed-loop automated system
• Equipped with nine safety protection functions, including short-circuit, overload, and hoisting limit protection
• PLC and variable-frequency control ensure smooth start-up and deceleration
• Reduces mechanical wear and improves overall operational stability
