Single-girder Overhead Crane: the "steel coil ferryman" of the steel workshop


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.

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 Capacity1-32 tons 
Span Range6-31.5 m
Lifting Height6-20 meters (standard), special orders up to 30 meters
Work DutyA 3-A 6 (A 3 Light Duty / A 5 Medium Duty / A 6 Heavy Duty)
Travel Speedmain 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.
