Single-girder Overhead Crane: the "steel coil ferryman" of the steel workshop
Classification:
Product Introduction
Steel coils pile up like mountains in steel workshops, and hoisting and transporting them is a critical factor in production line efficiency. Single-girder overhead cranes, with their lightweight, precise, and durable qualities, are the core of coil handling.

Features:
1. Precisely balancing "weight and lightness"
The single-girder structure doesn't compromise on strength—the customized design accommodates lifting of 5-20 ton steel coils (adapting to mainstream coil specifications). The main beam is welded from Q345B high-strength steel, minimizing the equipment's own weight while ensuring rigidity and easily lifting the "steel cylinder."
2. Threading the needle in the steel coil jungle
In a compact workshop with densely packed steel coils, the single-girder overhead crane achieves breakthroughs with its "dual precision":
Accurate positioning: Variable frequency speed regulation + electronic limiters achieve millimeter-level alignment, preventing coil collisions.
Space-saving: The single-girder layout saves 30% of overhead space compared to the double-girder layout, making it suitable for renovations of older workshops without requiring major infrastructure construction.
3. Withstanding the Harsh Environment of the Workshop
High temperatures, dust, and continuous operation... single-girder overhead cranes are engineered to be durable:
Core components such as motors and brakes are industrial-grade, with an IP 54 protection rating, making them impervious to dust and splashing water.
An anti-corrosion coating (such as zinc-rich epoxy) on the main beam combats corrosion and extends its service life by over 20%.
Technical Parameters:
| Lifting Capacity | 1-32 tons |
| Span Range | 6-31.5 m |
| Lifting Height | 6-20 meters (standard), special orders up to 30 meters |
| Work Duty | A 3-A 6 (A 3 Light Duty / A 5 Medium Duty / A 6 Heavy Duty) |
| Travel Speed | main beam: 20-40 m/min (variable speed) small trolley: 10-20 m/min |
From steel coil unloading and inter-area transport to storage and palletizing, single-girder overhead cranes utilize a "lightweight and efficient" approach to make the "heavy lifting" of steel workshops smarter and more labor-saving—making every lift an accelerator for improved production line efficiency.
