Overview
The Lower Rotating Beam Overhead Crane is an innovative lifting equipment specifically designed for space-constrained environments. By integrating low headroom construction with a rotating beam mechanism, it maximizes vertical and horizontal workspace utilization while ensuring efficient material handling. This crane is widely used in industries such as machinery manufacturing, automotive assembly, warehousing, logistics, and metallurgical processing, particularly in facilities with low ceiling heights requiring flexible operations.
Core Structure and Technical Features
1. Low Headroom Design
Space Optimization: Reduces main beam height by 30%–50% compared to traditional overhead cranes, eliminating the need for additional vertical clearance. Ideal for facilities with ceiling heights below 5 meters.
High-Strength Main Beam: Utilizes box-type beams or composite H-shaped steel beams, optimized via finite element analysis (FEA) to ensure load-bearing capacity and deformation resistance.
Compact Hoist System: Equipped with customized low-headroom wire rope hoists or chain hoists, achieving 10%–15% greater lifting height without compromising performance.
2. Rotating Beam System
Horizontal Rotation: The beam end features a rotating mechanism (typically ±180° rotation), extending coverage to previously inaccessible "blind zones" by 20%–40%.
Precision Positioning: Employs frequency-controlled motors or servo control technology, achieving rotational positioning accuracy of ±1° for tasks like precision assembly and mold alignment.
Dual Operational Modes: Supports manual rotation (emergency mode) and electric rotation (standard mode) to ensure operational continuity during contingencies.
3. Modular Drive System
Three-in-One Drive Unit: Integrates gearbox, motor, and brake into a compact end-carriage module, reducing noise to <65 dB and energy consumption by 15%.
Dual-Speed/Frequency Control: Adjustable trolley and bridge speeds (e.g., 20/5 m/min) enable smooth heavy-load starts and rapid light-load transfers.
4. Intelligent Control System
Wireless Remote Operation: Includes a 2.4GHz anti-interference remote controller with a 100-meter range, supporting multi-crane coordination.
PLC Integration: Optional PLC + touchscreen interface for speed adjustment, fault diagnostics, data logging, and MES system integration.
Safety Mechanisms: Incorporates overload protection, limit switches, emergency braking, voltage monitoring, and more, compliant with ISO 12482-1 standards.
