Top Running Bridge Crane

A top running bridge crane is a powerful overhead lifting solution that features a bridge mounted on top of two tracks, offering exceptional vertical and horizontal movement for a variety of industrial applications. Engineered for heavy-duty lifting tasks, these cranes are ideal for warehouses, manufacturing facilities, and shipping docks. With capacities that range from light to heavy loads, top running bridge cranes maximize productivity and space utilization, offering smooth and precise operation with customizable features.

Main Components

  • Electric Chain Hoist: The primary lifting mechanism powered by an electric motor, which drives the chain to facilitate vertical lifting and lowering of heavy loads.

  • Load Chain: Constructed from a high-strength alloy, this chain is designed to offer controlled, smooth movement during the lifting process.

  • Trolley: Supports the hoist and enables it to move horizontally along the crane’s girder. Available in both single and double girder configurations.

  • Girder: The fundamental structural component that holds both the hoist and trolley. Can be designed as either a profile or box girder, depending on the required specifications.

  • Hooks: Made from forged steel, these hooks meet stringent industrial safety standards for reliable lifting and secure attachment.

  • Control System: Includes a pendant control system (with a festoon cable) or the option for wireless remote control, giving operators full flexibility in crane operation.

  • Travel Motor & Drive: Provides stepless movement for smooth and accurate horizontal motion, enhancing operational efficiency.

  • Power Supply System: Uses either a drag chain or a cable system to ensure the safe and reliable transmission of power to the hoist, maintaining stable performance during operation.

 

Technical Specifications

  • Load Capacity: Capable of lifting loads up to 30 tons.

  • Hoisting Height (HOL): Maximum lifting height of 12 meters.

  • Hoisting Speed: Adjustable from 0.6 to 7 meters per minute, depending on the configuration.

  • Operating Temperature: Designed to operate within a temperature range of -10°C to +40°C.

  • Environment: Ideal for indoor applications.

  • Number of Hoists: Each crane is equipped with a single hoist.

  • Crane Configuration: Available in single girder or double girder design.

  • Girder Type: Profile girder (with a span of up to 12 meters) or box girder (with a span of up to 30 meters).

  • Travel Motion: Features stepless frequency control for smooth and adjustable travel.

  • Lifting Control: Offers options for single speed, dual speed, or stepless variable frequency control.

  • Power Supply to Hoist: Powered through flat cable or drag chain systems.

  • Rated Voltage: Operates at a voltage range of 380–415V / 50Hz or 440–480V / 60Hz.

  • Control Type: Equipped with pendant control (festoon system), with an optional wireless remote for convenient operation.

 

Key Advantages

  • Compact and Lightweight: Designed for easy installation and mobility, perfect for environments with limited vertical clearance.

  • Cost-Effective: Offers a budget-friendly solution with lower upfront and maintenance costs.

  • Precise Load Control: Ensures accurate vertical lifting and precise load positioning.

  • Quiet Operation: Delivers smooth, low-noise performance with minimal vibration, ideal for indoor use.

  • Simple Installation: Perfectly suited for small cranes, monorails, or ceiling-mounted systems, requiring minimal setup.
