General purpose overhead crane
Roof Rail-Mounted Workshop Bridge Crane
Product Overview
The Weiyuan LD Type Single Girder Overhead Bridge Crane is an efficient and cost-effective lifting solution designed to maximize vertical space in your workshop, warehouse, or manufacturing plant. Unlike gantry cranes, this bridge crane operates on runway rails mounted along the building’s support structure, leaving the floor clear of obstructions. It consists of a single main girder, two end carriages, and an electric hoist for lifting. Engineered for light to medium-duty applications, this crane offers reliable performance, easy operation, and full customization to meet your specific facility requirements.
Product Advantages
Space Optimization
By running on elevated rails, this overhead crane utilizes the building’s existing structure, freeing up valuable floor space for production, storage, and movement. Its design is ideal for facilities where floor-based systems are impractical.
Robust and Efficient Performance
Constructed from high-quality steel, the single-girder design offers an excellent strength-to-weight ratio. Paired with a powerful electric wire rope or chain hoist, the crane provides smooth, reliable, and efficient lifting and travel speeds, enhancing operational productivity.
Full Coverage of Work Area
The crane travels the entire length of the runway, and the hoist travels the full width of the bridge, providing complete rectangular coverage of the work area below. This ensures materials can be moved anywhere within the crane’s operational zone.
Enhanced Safety Systems
Safety is a core design principle. The crane is equipped with overload protection, an emergency stop system, and travel limit switches for both the hoist and the crane bridge. High-quality electrical components from brands like Siemens or Schneider ensure dependable operation.
Customizable and Versatile
Weiyuan offers complete customization of the crane’s capacity, span, lifting height, and control methods. Whether you need pendant control for direct operation or a wireless remote for greater flexibility and safety, we can tailor the crane to fit your exact workflow.
Application Scenarios
General Manufacturing and Workshops
Perfect for lifting raw materials, moving components between workstations, and loading finished goods. It is an essential tool for streamlining production processes in machine shops, fabrication plants, and assembly halls.
Warehousing and Storage
Ideal for handling heavy pallets, stock items, and equipment in warehouses and logistics centers. It allows for efficient organization and movement of goods without obstructing aisles.
Maintenance and Repair Facilities
Provides the lifting power needed for removing and installing heavy machinery, engines, and other large components, making maintenance tasks safer and more efficient.
Material Stockyards
Excellent for indoor or covered stockyards where materials like steel plates, coils, and bars need to be moved and sorted. It provides comprehensive coverage over the entire storage area.

FAQ
Q: What information do I need to provide to get a quote for a bridge crane?
A: To provide an accurate quote, we need to know your required lifting capacity, the span (distance between the runway rails), the lifting height (floor to hook), the length of the runway, your power supply details (e.g., 380V/50Hz/3P), and your preferred control method.
Q: What is the difference between a single girder and a double girder bridge crane?
A: A single girder crane (like this LD model) is lighter, more compact, and more cost-effective, making it ideal for capacities generally up to 20 tons and moderate spans. A double girder crane is used for heavier capacities, longer spans, and requires more headroom.
Q: Can this crane be installed in my existing building?
A: Yes, in most cases. The runway system can be attached to your building’s existing columns, provided they have the structural integrity to support the crane and its load. We can work with your building plans to ensure a proper and safe installation.
Q: What type of hoist is used with this crane?
A: This crane is typically paired with either an electric wire rope hoist or an electric chain hoist, depending on the application, capacity, and duty cycle. We will recommend the best hoist option for your specific needs.
Q: Do you offer installation services?
A: Yes. As a manufacturer with nearly 40 years of experience, Weiyuan can provide detailed installation drawings and instructions. We can also send our engineers to your site to supervise the installation and commissioning, or you can hire a local team with our online guidance.
