EOT Crane Structure Diagram

EOT crane is a fundamental piece of equipment in manufacturing, shromáždění, and storage operations. The defining characteristic of an EOT crane is that it operates on a fixed runway system, typically consisting of two parallel beams (runway rails) attached to the building’s support structure.

The crane itself “travels” along these rails, covering the length of the bay, while a hoisting mechanism moves across the crane’s bridge, covering the width. This combination of movements allows the crane to serve virtually every point within its rectangular working area.

Main Types of EOT Cranes

EOT Cranes are primarily categorized by their bridge structure and the number of beams they use. The two most common types are:

1. Jednonosníkový jeřáb EOT

A Jednonosníkový jeřáb EOT features one main bridge beam on which the hoist and trolley operate. The hoist is typically mounted on a trolley that moves along the bottom flange of the girder.

• Klíčové funkce:

  • 1. Nákladově efektivní: Simpler design and less material make it a more economical choice.
  • 2. Lighter Weight: Puts less stress on the building structure.
  • 3. Lower Headroom: Requires less vertical space, ideal for buildings with height restrictions.
  • 4. Easier Installation & Údržba: Simpler construction leads to faster setup and lower maintenance costs.

• Ideal For: Lighter to moderate duty cycles, capacities generally up to 20 tuny, and applications where cost and headroom are primary concerns. Common in workshops, sklady, and smaller manufacturing plants.

2. Dvounosníkový jeřáb EOT

A Double Girder EOT Crane is constructed with two main bridge beams that support the trolley and hoist. The trolley runs on rails mounted on top of the two girders.

• Klíčové funkce:

  • 1. Higher Lifting Capacity: Robust design allows for handling much heavier loads, often exceeding 100 tuny.
  • 2. Better Hook Height: The positioning of the hoist between the girders provides greater lift height compared to a single girder crane of the same building height.
  • 3. Zvýšená odolnost & Stabilita: Suitable for severe-duty, vysokocyklové aplikace.
  • 4. Flexibility for Attachments: Easier to integrate auxiliary devices like walkways, maintenance platforms, or magnet cable reels.

• Ideal For: Heavy-duty applications, frequent use, high capacities, ocelárny, slévárny, elektrárny, and large-scale shipping ports.

Other Common Variations

• Top-Running vs. Under-Running: This refers to how the crane moves on the runway. Top-running cranes (described above) ride on rails atop the runway beams. Under-running (or underhung) cranes have end trucks that suspend the crane from the bottom flange of the runway beams.

• Portální jeřáb: A variant where the bridge is supported by two or more legs running on fixed rails at ground level, instead of being attached to a building structure. It is essentially a “self-supporting” EOT crane.

Applications of EOT Cranes

aplikace

EOT Cranes are the workhorses of heavy industry due to their efficiency and reliability. Their primary application scenarios include:

• 1. Výrobní & Montážní linky: Moving raw materials, komponenty, and finished products between workstations.
• 2. Sklady & Storage Facilities: Loading and unloading heavy goods from trucks and organizing storage.
• 3. Ocelové mlýny & Výroba kovů: Handling raw steel coils, sheets, and fabricated metal structures.
• 4. Elektrárny: Installing and maintaining heavy equipment like turbines, generátory, and transformers.
• 5. Shipping & Porty: Used in shipyards for constructing and repairing ships, and in ports for handling containers and cargo (often as large gantry cranes).
• 6. Automotive Industry: Lifting vehicle chassis, engines, and large assembly jigs.
• 7. Hornictví & Cement Industry: Handling heavy machinery and bulk materials.
