The power supply system is configured around job site infrastructure, required machine mobility, operating routes, and environmental standards. Aicrane provides different power configurations to match fully mobile outdoor operations, fixed-route industrial handling, and low-emission electric applications.
For remote sites or large industrial yards without fixed electrical infrastructure, onboard diesel generator sets provide independent power for crane operation.
For operations with defined travel paths and available electrical infrastructure, cable reel systems provide continuous and reliable power supply.
For indoor facilities, noise-sensitive areas, and projects requiring cleaner operation, battery-powered systems provide flexible electric mobility.
The control system is customized according to handling precision, automation requirements, operator preferences, and site safety conditions. Aicrane integrates motion coordination, operator interfaces, and safety monitoring functions to ensure smooth and coordinated operation of hoisting, travel, and steering systems.
Control functions are configured according to crane operation methods, handling complexity, and required control accuracy:
Coordinates hoisting, travel, and steering movements through integrated logic control, enabling smooth interlocks and precise multi-motion coordination during complex handling operations.
Variable Frequency Drives (VFD) provide stepless speed regulation for hoisting and travel mechanisms. Soft-start and soft-stop functions reduce mechanical shock, while anti-sway control solutions can be integrated for improved load positioning during precise handling operations.
Safety functions are configured according to operating risks, traffic conditions, and surrounding equipment layout to achieve safe and reliable load handling.
Compact ultrasonic sensors installed around travel and steering areas provide real-time distance monitoring of nearby obstacles, personnel, and vehicles, helping reduce blind areas during RTG operation.
Load-cell-based monitoring continuously detects lifting load conditions and provides protection against overload operation and abnormal lifting situations.
Electronic travel limits and configurable protection zones restrict crane movement within predefined working areas and help prevent interference with surrounding equipment.
HMI-based monitoring records operating parameters, fault information, and maintenance alerts to support troubleshooting and improve equipment availability.
