Your statement highlights key advantages of single beam cranes, though the term "legitimate" might be a translation nuance—likely referring to certified, high-quality single beam cranes. These cranes are indeed favored in industries for their blend of intelligence (advanced features) and strong performance (efficiency and reliability). Let’s break down why and how they excel:

Why Are Single Beam Cranes Widely Adopted?

Intelligence & Automation

Smart Controls: Modern cranes use PLC (Programmable Logic Controller) systems for precise movement, reducing human error.

IoT Integration: Sensors monitor load weight, position, and stress in real time, enabling predictive maintenance and safety alerts.

Remote Operation: Some models support wireless control via tablets or smartphones, enhancing flexibility in hazardous environments.

Efficiency & Strength

High Load Capacity: Designed to handle heavy loads (e.g., 5-20 tons) with minimal deflection, thanks to robust steel construction.

Speed & Precision: Variable-frequency drives (VFDs) allow smooth, adjustable speed control, while laser positioning systems ensure accurate placement.

Modular Design: Easy to customize with attachments like magnetic lifters, vacuum grippers, or spreader beams for diverse tasks.

Cost-Effectiveness

Lower Installation Costs: Simpler to install than double-girder cranes, requiring fewer supports and reduced foundation work.

Energy Efficiency: VFD motors reduce power consumption during idle or light-load operations.

Key Industries Relying on Single Beam Cranes

Manufacturing: Assembly lines, metal fabrication, and auto plants use them for material handling.

Warehousing/Logistics: Speed up loading/unloading of containers or trucks.

Construction: Aid in lifting building materials or equipment on-site.

Improvement Suggestions for Future Designs

AI-Driven Optimization

Integrate machine learning to analyze usage patterns and auto-adjust settings (e.g., lifting speed, power output).

Enhanced Safety Features

Add collision-avoidance systems using LiDAR or 3D cameras.

Sustainable Energy

Hybrid or fully electric cranes with regenerative braking to capture and reuse energy.

Digital Twins

Create virtual replicas for simulation-based training, maintenance, and troubleshooting.
