4. Applications & Customer Case Study
The LDA Type Single-Girder Overhead Crane is ideal for machine shops, assembly workshops, warehouses, and storage yards, particularly suited for light to medium duty cycles with spans of 7–30 m and lifting capacities of 1–20 t. In 2025, a machinery factory in Henan replaced its 12-year-old equipment with three LDA Type 5-ton single-girder cranes. The retrofit increased the lifting speed from 5 m/min to 7 m/min, boosting daily handling capacity by approximately 30% and reducing average monthly fault shutdown time from 8 hours to under 1 hour. The total investment, including procurement, installation, and commissioning, was around ¥180,000, with the cost recovered within 6 months.

Frequently Asked Questions
Q: What is the difference between the LDA Type and LD Type single-girder overhead cranes?
A: The LDA and LD are essentially the same model with different naming conventions. The LDA is an improved version of the LD, featuring optimizations in electrical control and safety protection, while the structural parameters remain largely consistent.
Q: Can the single-girder overhead crane be custom manufactured to non-standard specifications?
A: Yes. Both the span and lifting height can be customized. The maximum lifting capacity is 20 tons, and the maximum span is 40 meters. Simply provide the lifting capacity, span, and lifting height when placing your order.
Q: How much does an LDA Type crane cost?
A: The price depends on the lifting capacity and span. A standard 1-ton model costs approximately ¥10,000–20,000, a 5-ton model costs around ¥30,000–50,000, and a 10-ton model is priced at roughly ¥50,000–80,000. This includes transportation from our factory to your site, installation & commissioning, and training. Please provide your specifications for an accurate quotation.
