Custom Multi-Point Suspension Overhead Crane for Large-Span and Load-Sensitive Industrial Buildings

The multi-point suspension overhead crane is a specialized underhung overhead crane specifically designed for ultra-wide-span facilities and unique building structures.

It is available in both single-girder and double-girder configurations, providing flexible solutions for complex industrial environments.

Multi-Point Single Girder Electric Suspension Crane

Multi-Point Double Girder Electric Suspension Crane

Explosion-Proof Multi-Point Suspension Overhead Crane

By means of a multi-point (multi-rail) suspension system, the crane distributes its self-weight and lifting loads evenly to the roof structure, effectively reducing single-point stress and structural load concentration.
This design makes it particularly suitable for industrial buildings with limited roof load capacity and extremely large spans.

Typical applications include, but are not limited to:

• Aircraft manufacturing plants
• Aircraft maintenance and assembly hangars
• Ultra-wide-span industrial workshops
• Warehouses with height restrictions or stringent requirements for unobstructed floor space

Compared with conventional overhead cranes or standard underhung cranes, the multi-point suspension solution not only addresses lifting requirements but also significantly reduces overall building construction costs from a structural engineering perspective.

Multi-Point Single Girder Electric Suspension Crane

The multi-point electric single girder underslung crane maintains a lightweight structural design while evenly distributing loads through multiple suspension points, resulting in more reasonable and balanced stress on the single girder. This design makes it particularly suitable for applications involving medium lifting capacities and ultra-large spans.

Key Advantages / Features

• Multi-point support structure

Multiple suspension points distribute the crane's self-weight and working load, significantly reducing single-point stress. This results in more uniform girder loading, effectively minimizing main girder deformation and operational vibration, while enhancing overall structural stability and safety.

• Integrated three-in-one drive system (Motor + Reducer + Brake)

High-integration three-in-one drive units ensure excellent synchronization among all suspension points. The crane operates smoothly, reducing structural stress caused by asynchronous multi-point movement.

Multi-Point Double Girder Electric Suspension Crane

The multi-point double girder electric suspension crane is designed for higher lifting capacities and applications requiring superior stability, particularly in ultra-wide-span facilities.

By combining a double girder structure with a multi-point suspension system, the crane achieves outstanding operational smoothness and positioning accuracy while maintaining high load-bearing capability.

Key Advantages / Features

• Roof-mounted suspension layout with 100% unobstructed floor space

Both the crane and runway rails are fully suspended beneath the roof structure, with no columns or supports on the floor. This provides complete freedom for production line layout, equipment installation, material storage, and personnel movement.

• Significant reduction in building structure and construction costs

The multi-point load distribution effectively reduces roof structural stress, enabling lower building height requirements and reduced steel consumption, thereby cutting overall construction costs at the source.

• Modular design for future upgrades

The modular design allows the crane system to be easily expanded or modified to accommodate process changes or facility layout adjustments, protecting long-term investment value.

Explosion-Proof Multi-Point Suspension Overhead Crane

The explosion-proof multi-point single girder suspension crane is developed on the basis of standard multi-point suspension architecture and is specifically designed for flammable, explosive, or other hazardous industrial environments. It combines enhanced safety performance with excellent adaptability to ultra-wide-span structures.

The core hoisting mechanism, traveling mechanisms, and electrical systems are all equipped with components compliant with explosion-proof standards, effectively reducing safety risks caused by electrical sparks, frictional heat generation, or static electricity accumulation. This ensures reliable and safe operation under high-risk working conditions.

Key Advantages / Features

• Explosion-proof electric hoist to eliminate potential ignition sources

The crane is equipped with an explosion-proof electric hoist. The hoisting motor, brake, and electrical components are all designed with explosion-proof protection to prevent the release of electrical sparks.
The enclosure offers high sealing performance and mechanical strength, preventing flammable gases or dust from entering the system.

• Fully roof-suspended structure for unobstructed floor operations

Both the crane and runway are completely suspended beneath the roof, fully freeing floor space and meeting strict requirements for personnel evacuation and equipment layout in hazardous areas.

• Reduced roof load for optimized building design

The multi-point suspension structure significantly reduces concentrated roof loads, helping to lower building height requirements and structural complexity while controlling construction costs in compliance with explosion-proof regulations.

• Modular system for flexible future adjustments

The modular design allows suspension and traveling systems to be flexibly adjusted during future process upgrades or facility renovations, improving overall adaptability.

Customization Options

The multi-point electric suspension crane is a highly customized lifting solution, designed according to specific project requirements, including:

• Rated lifting capacity
• Span and number of suspension points
• Runway rail configuration
• Hoisting and traveling speeds
• Control modes (pendant, remote control, automation)
• Explosion-proof classification (for explosion-proof models)

A Crane Solution Designed for Building Structures

The multi-point electric suspension crane is not a conventional “standard crane product,” but rather a system-level lifting solution centered on structural compatibility with building design.

For projects involving ultra-wide spans, limited roof load capacity, or extremely high demands on space utilization, the multi-point suspension solution is often safer, more economical, and more valuable over the long term.
