EOT Crane

What is an EOT Crane?

EOT Crane Structure Diagram

EOT crane is a fundamental piece of equipment in manufacturing, مونتاژ, 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. جرثقیل EOT تک تیر

جرثقیل EOT تک تیر

5 تن جرثقیل EOT تک تیر

الف جرثقیل EOT تک تیر 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.

• ویژگی های کلیدی:

  • 1. مقرون به صرفه: Simpler design and less material make it a more economical choice.
  • 2. وزن سبک تر: استرس کمتری به سازه ساختمان وارد می کند.
  • 3. Lower Headroom: Requires less vertical space, ideal for buildings with height restrictions.
  • 4. Easier Installation & نگهدار: Simpler construction leads to faster setup and lower maintenance costs.

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

2. جرثقیل EOT دو تیر

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.

• ویژگی های کلیدی:

  • 1. Higher Lifting Capacity: Robust design allows for handling much heavier loads, often exceeding 100 تن.
  • 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. دوام افزایش یافته & ثبات: Suitable for severe-duty, کاربردهای چرخه بالا.
  • 4. Flexibility for Attachments: Easier to integrate auxiliary devices like walkways, maintenance platforms, or magnet cable reels.

• Ideal For: Heavy-duty applications, استفاده مکرر, high capacities, کارخانه های فولاد, ریخته گری ها, نیروگاه ها, 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.

• جرثقیل گانی: 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

کاربرد

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

• 1. تولید & خطوط مونتاژ: Moving raw materials, اجزاء, and finished products between workstations.
• 2. انبارها & Storage Facilities: Loading and unloading heavy goods from trucks and organizing storage.
• 3. کارخانه & ساخت فلزی ساخت فلزی: Handling raw steel coils, sheets, and fabricated metal structures.
• 4. نیروگاه: Installing and maintaining heavy equipment like turbines, ژنراتور, و ترانسفورماتورها.
• 5. حمل و نقل & درگاه: 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, موتورها, and large assembly jigs.
• 7. معادن & Cement Industry: Handling heavy machinery and bulk materials.
