Overhead Bridge Crane Specifications and Models

Introduction to Overhead Bridge Cranes

Overhead bridge cranes usually operate on parallel runways, enabling the bridge to move horizontally while the hoist lifts vertically. They are versatile, with different configurations to suit specific industrial requirements. This article explores the specifications, models, and applications of overhead bridge cranes.

Key Specifications of Overhead Bridge Cranes

Understanding overhead bridge crane specifications is critical for selecting the right model for your operations. Here are the main specifications to consider:

1. Load Capacity

• Load capacities typically range from 1 ton to over 300 tons.
• Single girder cranes are ideal for lighter loads, such as 5-ton single girder models, while double girder cranes handle heavier loads.

2. Span Length

• The span refers to the width between the runways.
• Common spans range from 10 to 40 meters, depending on the application and workspace.

3. Lifting Height

• Lifting height refers to the vertical distance the hoist can lift a load.
• It ranges from 6 meters to over 30 meters, accommodating different industrial needs.

4. Hoist Type

• Wire rope hoists are used for high-capacity operations requiring smooth operation.
• Chain hoists are suitable for lighter loads and compact spaces.

5. Operational Speed

• Variable speeds for hoisting and bridge movement enhance control and efficiency.

6. Duty Cycle

• The crane's duty cycle reflects its ability to handle frequent or continuous operation.
• Applications requiring heavy usage require cranes with a higher duty cycle rating.

7. Power Supply

• Overhead cranes are usually powered by electricity, with options for single-phase or three-phase systems.

Types of Overhead Bridge Cranes

Overhead bridge cranes are categorized by their structure and application. Below are the primary types:

1. Single Girder Overhead Cranes

• Design: Feature one main girder.
• Applications: Ideal for light to medium-duty tasks, such as in workshops and warehouses.
• Popular Models:
  • 5-ton Single Girder Overhead Crane: Compact and cost-effective.
  • Explosion-Proof Single Girder Overhead Crane: Suitable for hazardous environments.
  • Single Girder Suspension Crane: Ideal for areas with low headroom.
  • Top-Running Single Girder Overhead Crane: Maximizes floor space and provides efficient load handling.

2. Double Girder Overhead Cranes

• Design: Include two girders for increased strength and capacity.
• Applications: Used for heavy-duty operations in factories, steel mills, and power plants.
• Popular Models:
  • Explosion-Proof Overhead Crane: Designed for environments with flammable materials.
  • Grab Bucket Crane: Equipped with specialized buckets for bulk material handling.
  • European Double Girder Crane: Offers advanced technology for precise operations.
  • Double Trolley Overhead Crane: Features dual trolleys for handling multiple loads simultaneously.
