EOT CRANES

उत्पाद वर्णन

EOT (Electric Overhead Traveling) Cranes, often simply called Electric Overhead Cranes or Bridge Cranes, are a fundamental piece of equipment in countless industrial and commercial settings for lifting, lowering, and moving heavy materials.

Let's break down what makes them "Electric Overhead Traveling Cranes":

1. Electric: This signifies that all the movements of the crane are powered by electric motors. This includes:

   • Hoisting: The vertical movement of lifting and lowering the load.

   • Trolley Travel: The horizontal movement of the hoist along the bridge girder (crosswise to the runway).

   • Bridge Travel: The horizontal movement of the entire crane bridge along the length of the building (longitudinal to the runway).

2. Overhead: This refers to their operational position. EOT cranes are installed on elevated runways or rails, typically attached to the building's structural columns or a separate support structure. This allows them to operate above the workspace, keeping the floor clear for other activities, personnel, and equipment.

3. Traveling: This highlights their mobility within a defined area. The crane's bridge travels along the length of the building on its runways, and the hoist/trolley travels across the width of the bridge. This two-dimensional travel capability allows the crane to cover a large rectangular area, providing flexibility in material handling.

Key Components of an EOT Crane:

• Bridge (or Bridge Girder): The main horizontal beam(s) that spans the width of the bay. It carries the trolley and hoist.

  • Single Girder: One main beam.

  • Double Girder: Two main beams.

• End Carriages (or End Trucks): Located at each end of the bridge, these contain the wheels that travel along the runway rails.

• Hoist: The mechanism that lifts and lowers the load. It consists of an electric motor, gearbox, drum (for wire rope), and the hook block.

• Trolley: The assembly that houses the hoist and travels along the bridge girder.

• Runway System: The parallel rails (and their supporting structure) mounted to the building, on which the entire crane travels.

• Control Panel: Houses the electrical components, contactors, and protective devices for the crane's operation.

• Controls: Can be pendant control (hanging from the crane), radio remote control, or sometimes cabin control for large cranes.

• Safety Devices: Limit switches (for hoist and travel motions), overload protection, emergency stop buttons, anti-collision systems, brakes, etc.

Advantages of EOT Cranes:

• Space Utilization: Frees up floor space by operating overhead.

• Efficiency: Streamlines material handling, speeding up production and logistics.

• Safety: Reduces manual handling risks and enhances workplace safety with various built-in features.

• Versatility: Adaptable for a wide range of industries and applications, with customizable capacities and spans.

• Precision: Offers accurate positioning of loads.

• Durability: Built for heavy-duty, long-term operation.

EOT cranes are indispensable in industries such as manufacturing, steel mills, foundries, fabrication shops, warehouses, power plants, and many others where heavy and bulky materials need to be moved safely and efficiently.
