General purpose overhead crane
Electric Suspension Single Girder Bridge Crane with Wire Rope Hoist
Product Overview
The Weiyuan Electric Suspension Single Girder Bridge Crane is a light-duty, high-efficiency lifting solution designed for modern workshops and industrial facilities where maximizing floor space is a priority. Also known as an underhung or under-running crane, it operates on a track suspended from the building’s roof structure, eliminating the need for support columns on the floor. Paired with a reliable electric wire rope hoist (CD/MD model), this crane offers a compact, cost-effective, and versatile system for material handling, assembly, and maintenance tasks across a wide range of industries.
Product Advantages
Maximum Space Utilization
By running on an I-beam track attached to the ceiling, this crane frees up the entire factory floor. Its low-headroom design is perfect for buildings with limited vertical clearance, allowing for the highest possible lifting height in constrained spaces.
Lightweight and Economical Design
This crane features a light dead weight and a compact structure, which reduces the overall load on the building’s support system. This makes it an economical choice, as it often requires less structural reinforcement and can be installed in buildings not suited for heavier top-running cranes.
Stable and Reliable Performance
The main girder is engineered with a welded beam structure, providing excellent vertical and horizontal rigidity for stable operation. Paired with a robust CD (single speed) or MD (double speed) electric wire rope hoist, it delivers dependable and consistent lifting performance for daily operations.
Comprehensive Safety Systems
Safety is paramount. The crane is fully equipped with essential safety features, including an overload protection system that provides a sharp warning, an emergency brake function, high-quality polyurethane buffers, and a hook with a safety latch to ensure secure lifting.
Easy Installation and Customization
The end girders are connected to the main girder with high-strength bolts, simplifying transportation and installation. Weiyuan offers full customization of lifting capacity, span, and height to meet your specific application requirements and facility layout.
Application Scenarios
Manufacturing and Production
Ideal for general manufacturing workshops, assembly lines, and processing plants for moving raw materials, components, and finished goods between workstations with efficiency and ease.
Warehousing and Storage
An excellent choice for warehouses where clear floor space is needed for forklift traffic and storage racks. It facilitates efficient loading and unloading of inventory.
Maintenance and Repair Shops
Provides a safe and effective method for lifting heavy equipment, engines, and parts in maintenance workshops and garages, reducing manual effort and improving workplace safety.
Light Industrial Facilities
Perfectly suited for any light-duty industrial setting that requires a reliable, space-saving overhead lifting solution without the cost and complexity of a heavy-duty crane system.

FAQ
Q: What is the difference between a suspension crane and a regular overhead crane?
A: A suspension crane (or underhung crane) runs on the bottom flange of a runway track that is suspended from the ceiling. A regular (top-running) overhead crane travels on rails mounted on top of runway beams supported by floor columns. Suspension cranes are ideal for saving floor space and for buildings that cannot support columns.
Q: Is a structural assessment of my building required for installation?
A: Yes. Because the crane hangs from the roof structure, it is crucial to have a qualified engineer verify that your building’s ceiling can safely support the full weight of the crane and its maximum rated load.
Q: What is the difference between a CD and an MD model hoist?
A: The CD model is a single-speed electric hoist, which is suitable for general-purpose lifting at a constant speed. The MD model is a double-speed hoist, offering both a fast speed for efficiency and a slow speed for precise positioning, which is ideal for delicate or alignment-sensitive tasks.
Q: What control methods are available?
A: We offer both ground-based pendant control for direct operation and wireless remote control. The remote control option provides greater flexibility and allows the operator to maintain a safe distance from the load.
Q: How does Weiyuan ensure product quality?
A: With nearly 40 years of manufacturing experience, Weiyuan adheres to a strict ISO-compliant quality control system. Each crane is built using high-quality materials and components. We conduct thorough testing on all equipment before it leaves our factory and provide a detailed test report with every order to guarantee its safety and performance.
