Amtech Electronics (India) Ltd has developed a groundbreaking control and monitoring system for EOT (Electric Overhead Traveling) cranes equipped with four-rope grabs. This innovative system integrates the operation of the crane with a variable frequency drive and crane controller, offering precise control and efficient monitoring. By eliminating mechanical synchronization issues and incorporating advanced automation, Amtech has revolutionized the handling of powder materials in industries such as cement, metal, and ports. Let's explore the features, benefits, and impact of this new generation control system.
Enhancing Grabbing Crane Efficiency:
Traditional grabbing cranes relying on mechanical synchronization through a differential gearbox often face problems such as backlash and time-consuming re-synchronization. However, Amtech's automation system overcomes these limitations. By employing a properly sized variable frequency drive, the automation system seamlessly controls operations like cross travel, long travel, hoisting, grabbing, and safety interlocks. The PLC system ensures speed control, thruster control, synchronization, and various interlocks, resulting in optimized performance.
Intelligent Grabbing Mechanism:
The four-rope grab mechanism employed in powder material handling plays a crucial role in the crane's efficiency. Amtech's control system offers both hydraulic and electrical operation options. In the electrical system, two rope and drum assemblies on the crab trolley facilitate grab operation, driven by an electrical motor. The motors are controlled by drives, allowing multiple speed operations, enhancing flexibility and productivity.
Overcoming Frequent Challenges:
The traditional grab control systems suffer from several common problems, including the limitations of mechanical differential limit switches and frequent replacements of power and rotor resistance contactors. Slip-ring and carbon brush maintenance, single phasing issues, burning of resistor boxes, and regular maintenance of current carrying contacts further compound these challenges. Amtech's system addresses these issues, resulting in a more reliable and efficient grabbing crane.
Key Features of the Control System:
Retrofitting capability using existing slip-ring motor or new induction motor.
