General purpose overhead crane
Double-Sided Cantilever Electric Suspension Single Girder Bridge Crane
Product Overview
The Weiyuan Double-Sided Cantilever Suspension Bridge Crane is an innovative and highly versatile lifting solution designed to maximize coverage and operational flexibility. This crane features a single girder that extends beyond its runway tracks on both sides, creating cantilevers that allow the hoist to reach areas outside the main bay. As a suspension (or underhung) crane, it runs on the lower flange of a ceiling-mounted track system, preserving valuable floor space. This makes it ideal for facilities that need to service adjacent workstations, load/unload areas, or spaces not directly covered by the main crane runway.
Product Advantages
Expanded Work Area Coverage
The double cantilever design is the key advantage, extending the hoist’s travel path beyond the span. This allows for efficient material handling between the main bay and adjacent areas, effectively increasing your operational footprint without needing a wider crane structure.
Optimal Space Utilization
By mounting to the existing roof structure, this suspension crane keeps the factory floor clear of columns and support structures. This is especially beneficial in workshops with limited ground space or complex layouts, allowing for unobstructed movement of personnel and equipment below.
Lightweight and Economical
Engineered with a light dead weight and compact dimensions, the crane minimizes the load on the building’s support structure. This often translates to lower installation costs and makes it a viable option for buildings not designed to support heavier crane systems.
Durable and Reliable Construction
Built with a robust welded beam structure, the main girder offers high vertical and horizontal rigidity. Combined with high-quality components and reliable electric hoists (CD/MD models), this crane is designed for durability and consistent performance in demanding industrial environments.
Enhanced Safety and Control
Equipped with a full suite of safety features, including overload protection, emergency brake systems, and high-quality rubber buffers. The crane can be operated via remote control or a pendant, keeping the operator at a safe distance while maintaining precise control over lifting operations.
Application Scenarios
Workshops with Adjoining Bays
Perfect for manufacturing facilities where materials need to be moved from a central assembly area to adjacent workstations or finishing areas. The cantilevers provide seamless service to these side zones.
Loading and Unloading Docks
Ideal for lifting goods from inside a facility and positioning them onto trucks or loading platforms located just outside the main runway path, streamlining logistics and shipping operations.
Maintenance and Assembly Stations
Excellent for lifting and moving parts over machinery or assembly lines that are positioned near the crane’s main path. The cantilever reach allows for servicing equipment without requiring a larger crane.
Facilities with Architectural Constraints
A superior choice for buildings where supporting columns for a top-running crane are not feasible. The suspension design utilizes the existing ceiling structure for a space-saving and effective lifting solution.

FAQ
Q: What is the main benefit of the double-sided cantilever feature?
A: The double cantilevers allow the hoist to travel beyond the crane’s runway beams on both sides. This extends your lifting area, enabling you to serve workstations, loading zones, or storage areas that are adjacent to, but not directly under, the main crane bay.
Q: Can this crane be installed in a building that wasn’t originally designed for a crane?
A: Because it is a lightweight suspension crane that hangs from the roof structure, it is often a suitable choice for existing buildings. However, a professional evaluation of your roof’s load-bearing capacity is essential. We can work with your engineers to ensure a safe and proper installation.
Q: Is the cantilever length fixed, or can it be customized?
A: The cantilever length is customizable. We design it based on your specific needs, taking into account factors like the crane’s main span and lifting capacity to ensure stability and safety during operation.
Q: What kind of environment is this crane suitable for?
A: This crane is designed for general indoor industrial applications, such as workshops, warehouses, and assembly plants. It is prohibited for use in combustible, explosive, or highly corrosive environments unless specifically designed with explosion-proof features.
Q: What quality and safety guarantees does Weiyuan provide?
A: With nearly 40 years of experience, Weiyuan manufactures all cranes under a stringent, ISO-compliant quality control system. Each crane is equipped with multiple safety features like overload protection and emergency stops. We conduct rigorous pre-shipment testing and provide a complete test report with every order to ensure it meets our high standards and your expectations.
