Single-girder overhead crane: the "space power link" of heavy machinery workshops
In a heavy-duty machining workshop, metal rollers over two meters in diameter and weighing several tons are neatly stacked, and CNC lathes emit a deep, grinding roar. How can these "steel behemoths" be efficiently moved through the workshop? A single-girder bridge crane spanning the factory floor provides the answer. Its red main beam acts as a steel backbone, and its electric hoist acts as a precise gripper. It accomplishes "ton-level lifting and millimeter-level docking" within a confined space, becoming the dual pillars of efficiency and safety in heavy-duty manufacturing.
TEchnical Parameters:

| Lifting Speed | No-load 0.5-12m/min, full-load 0.2-8m/min (frequency control) |
| Travel Speed | 0.5-45m/min (main beam running speed along the track) |
| Work Duty | A 3 (light), A 4 (intermediate), A 5 (heavy) |
Single-girder Structure: The Optimal Solution for Workshop Space
The core competitiveness of single-girder bridge cranes lies in their "lightweight + strong load-bearing" design philosophy:
Innovative main girder: Forged from Q345B low-alloy, high-strength steel (the red main girder in the image is a box-type structure), it boasts a 30% weight reduction compared to traditional double-girder cranes, yet achieves a rated load range of 5-20 tons through material mechanics optimization (suitable for workpieces commonly found in heavy machinery workshops, such as rollers, machine bases, and drive shafts).
Spatial Adaptability: The rails are mounted on factory columns or trusses, eliminating the need for additional load-bearing structures and saving over 20% of overhead space (especially suitable for heavy-duty processing areas with dense equipment and limited floor height, such as those shown in the image).
Modular Layout: The plug-and-play design of the electric hoist and main girder allows the equipment to be quickly adapted to varying spans (7.5-22.5 meters) and lifting capacity requirements, flexibly responding to production line adjustments.
Unlimited Scenario: A Multifaceted Expert in Heavy Manufacturing
The adaptability of single-girder overhead cranes allows them to penetrate deeply into the entire process of heavy machinery workshops:
Raw Material Hoisting: Lifting steel ingots and forgings (10-15 tons) from the raw material storage area, combined with overhead cranes to achieve seamless transportation from the stockpile to the production line;
Processing and Support: As shown in the scenario shown, lifting metal rollers to CNC lathes (with an accuracy of ±0.02mm) replaces the traditional inefficient "forklift + manual push" method, increasing processing efficiency by three times;
Finished Product Transfer: Lifting assembled heavy machinery components (such as rolling mill rollers) to the coating line, avoiding surface scratches caused by dragging on the ground;
Equipment Maintenance: Lifting 5-10 ton machine tool spindles and gearboxes, maneuvering flexibly in narrow workshop aisles, reduces maintenance time from three days of production down to eight hours.
