Single-girder bridge crane: "new efficiency engine" in old workshop
On the mottled concrete floor, a forklift awaits the transfer of the next batch of metal sheets; beneath the rusted trusses, a yellow single-girder bridge crane hovers quietly. In this industrial workshop densely packed with equipment and cramped space, this seemingly "traditional" lifting equipment, with its "small and beautiful" design logic, has become an invisible engine that activates production efficiency.
TEchnical Parameters:
| Lifting Capacity | 1 t, 2 t, 3 t, 5 t, 10 t, 16 t, 20 t (customizable up to 32 t) |
| Span | 7.5m, 10.5m, 13.5m, 16.5m, 19.5m, 22.5m (custom span ≤ 30m) |
| 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 | A3 (light), A4 (intermediate), A5 (heavy) |
Single-girder cranes offer space savings in older workshops. The pain points of older workshops often lie in space utilization: densely packed columns, limited floor heights, and equipment cluttering the floor. The single-girder overhead crane's lightweight and modular design addresses this challenge:
Track-mounted installation: The main girder (the yellow beam in the image) is mounted directly on the workshop trusses or columns, eliminating the need for a separate load-bearing platform. This reduces overhead space by over 30% (and allows for two more pieces of processing equipment compared to a double-girder crane).
Narrow main girder design: Forged from I-beams or box beams, the design is only 0.8-1.2 meters wide, making it easy to navigate through the "jungle of equipment" in a workshop (such as the narrow aisle between the welding machine and material racks in the image).
Flexible span customization: Available in a 7.5-22.5-meter span, it accommodates the non-standard column spacing of older workshops (such as the irregular truss spacing in the image), allowing a single roll to cover multiple workstations.

Unlimited Applications: Beyond the Workshop, a Multifaceted Approach
The adaptability of single-girder overhead cranes allows them to transcend the boundaries of traditional workshops, becoming a universal tool for industrial applications:
Warehousing and Logistics: In integrated "production + warehousing" workshops like the one shown in the image, overhead cranes can directly lift palletized cargo (such as the yellow bins) and, in conjunction with forklifts, achieve "air + ground" intermodal transport, increasing warehouse turnover by 50%;
Equipment Maintenance: Hovering operations can be performed near machine tools and punch presses, lifting components awaiting repair (such as welding machines), reducing maintenance time from three days of downtime to eight hours;
Light Industry Transformation: When transforming old workshops into food and pharmaceutical production lines, single-girder overhead cranes, with their stainless steel construction and dust-resistant design, seamlessly adapt to clean production requirements.
