1. What is a Single Girder Overhead Crane?
A single girder overhead crane consists of a single main beam, end carriages, an electric hoist, traveling mechanisms, and an electrical control system. The electric hoist moves along the lower flange of the main beam to achieve three-dimensional movement of heavy loads. Compared to double girder structures, it features a more lightweight design and is highly suitable for scenarios with smaller lifting capacities and moderate spans. It is the ideal choice for small-to-medium-sized factories, warehouses, and maintenance workshops.
2. Key Features
Compact Structure & Lightweight: Requires less steel material and exerts lower load demands on factory buildings, making it perfect for old factory renovations or new projects aiming to reduce costs.
High Economic Value: Procurement and installation costs are 30%–40% lower than those of double girder cranes of the same specifications, ensuring a fast return on investment.
Flexible Operation & Easy Maintenance: Features highly integrated electric hoists; daily maintenance only requires checking the wire rope, limit switches, and brakes.
Strong Adaptability: Lifting capacities range from 1 to 20 tons, and spans range from 7.5m to 31.5m. Non-standard customization is available, and the installation cycle can be shortened by approximately 30%.
3. Application Scenarios
Loading and unloading in mechanical processing workshops, logistics handling in warehouses, hoisting on assembly lines, replacing heavy components in equipment maintenance areas, and transporting medium-duty materials in small foundries and building material plants.
