Type of Overhead Crane
Bridge Cranes: Feature a hoist that runs along a bridge between two parallel runways. These are common in manufacturing environments.
Gantry Cranes: Similar to bridge cranes, but the bridge is supported by legs mounted on wheels or rails. Suitable for outdoor use.
Jib Cranes: Consist of a horizontal jib or boom that supports a moveable hoist. They are fixed to a wall or floor-mounted pillar.
Monorail Cranes: Feature a single rail system; ideal for processes requiring linear movement of materials.
Workstation Cranes: Designed for lighter loads and more repetitive tasks, often found in smaller workspaces.
Capacity
Light Duty: Up to 2 tons. Ideal for light assembly operations or repair shops.
Medium Duty: 2 to 10 tons. Suitable for machine shops and general industrial applications.
Heavy Duty: Over 10 tons. Used for large scale lifting tasks in heavy manufacturing or construction.
Control Method
Manual: Operated by hand, suitable for very light loads and infrequent use.
Electric: Controlled electrically, most common due to their ease of use and capability to handle larger loads.
Remote-Controlled: Allows operation from a distance, enhancing safety and visibility.
Application
Automotive: For assembly lines or handling of automotive parts.
Construction: For moving materials on construction sites.
Manufacturing: For assembly lines, warehousing, and material handling.
Shipping & Logistics: For loading and unloading goods in ports and docks.
Configuration
Single Girder: One main bridge; ideal for lighter loads and shorter spans.
Double Girder: Two parallel bridge beams; suited for heavy loads and long spans.
Features
Adjustable Speed: Can vary the speed for different operations.
Variable Frequency Drives (VFD): For precision control of motor speed and torque.
Automated Systems: Integrated with automated production systems for synchronized operation.
Safety Features: Include overload sensors, emergency stops, and anti-collision devices.
Understanding these categories helps in selecting the right overhead crane for specific needs based on operational requirements and environmental conditions.
