Double Girder Top Running Bridge Cranes: A Comprehensive Guide
Double girder top running bridge cranes are essential material handling equipment widely used in various industries across China. These cranes, offered by manufacturers like those found at www.dowell-cranes.com and www.chinacranemanufacturer.com, are known for their robust construction and high lifting capacity. This guide delves into their technical features, different types, and operational aspects.
Understanding Double Girder Top Running Bridge Cranes
These cranes consist of two main girders running on an elevated runway system. The top-running design means the crane’s wheels run on top of the runway beams. This configuration offers several advantages, including increased headroom and improved stability. The two girders provide enhanced load-bearing capacity compared to single-girder cranes. They are particularly suitable for heavy-duty applications. Companies like Kino Cranes, showcased on www.chinacranemanufacturer.com, are leading suppliers.

FAQs
1. What is the difference between a single and double girder crane?
Double girder cranes offer greater lifting capacity and span compared to single girder cranes, making them suitable for heavier loads and wider work areas. Single girder cranes are more cost-effective for lighter loads and smaller spans.
2. What are the safety features in these cranes?
Standard safety features include overload protection, limit switches, emergency stop systems, and braking mechanisms. More advanced models may include anti-sway devices and other safety enhancements.
3. How much maintenance do double girder cranes require?
Regular inspections, lubrication, and component replacements are necessary. The frequency depends on usage intensity and environmental conditions. Manufacturers provide maintenance guidelines.
4. What factors influence the cost of a double girder crane?
Capacity, span, lift height, features (e.g., explosion-proof design), and customization requests all significantly impact the overall cost.
5. What is the typical delivery time for a new double girder crane?
Delivery time varies depending on the manufacturer, crane specifications, and order volume. It can range from a few weeks to several months for customized orders.
