Different Types of Single Girder Overhead Cranes
Single girder overhead cranes are available in various configurations, each suited to different operational requirements and environmental constraints. The following table highlights the key differences between some common types:
| Type | Description | Advantages | Disadvantages |
|---|---|---|---|
| LD Type | Standard design, often with a U-shaped main girder. | Cost-effective, widely applicable. | Limited lifting height. |
| Low Headroom Type | Designed for applications with limited vertical space. The hoist travels below the main girder. | Maximizes lifting height in constrained spaces. | More complex design, potentially higher cost. |
| LDP Type | Similar to low headroom, but hoist travels along one side of the main girder. | Optimized for specific space constraints. | Limited applicability. |
| Underslung Type | The crane structure is mounted below the runway beam. | Saves headroom. | Limited load capacity. |
| European Standard Type | Designed to meet the European FEM standard. Usually features a box-type girder and advanced control systems. Examples are available on www.krcrane.shop. | Improved safety, reliability, and efficiency. | Higher initial cost. |
