Bridge cranes are designed with several essential components that ensure their functionality and efficiency. Below is a comparison table highlighting the key technical features of bridge cranes.
| Feature | Description |
|---|---|
| Capacity | Ranges from 1 ton to over 500 tons, depending on the design and application. |
| Span | The distance between the runway beams, typically ranging from 10 feet to over 200 feet. |
| Lift Height | The maximum vertical distance the hook can travel, influenced by building height and crane design. |
| Speed | Includes bridge travel speed, trolley speed, and hoist speed; can be customized for specific needs. |
| Control Systems | Options for manual pendant control, radio remote control, or automated control systems. |
| Duty Cycle | Classification based on usage frequency and load handling, ranging from infrequent to continuous use. |
| Construction Material | Typically made from steel or aluminum for strength and durability. |
| Safety Features | Includes overload protection, emergency stop buttons, and anti-collision systems for operator safety. |
Types of Bridge Cranes
Bridge cranes come in various configurations tailored to specific lifting needs. The following table summarizes the primary types of bridge cranes and their characteristics.
| Type | Description | Best Suited For |
|---|---|---|
