Single Girder EOT Crane

The core structure of the single girder eot crane consists of a bridge supported at both ends by end cars running along the runway beam. A crane and trolley mechanism moves along the bottom flange of the main beam, providing lifting and lateral movement. Single girder EOT cranes are known for their cost-effectiveness, simplicity and reliability, making them the ideal solution for a variety of light to medium duty applications. The crane operates on elevated runway rails, freeing up valuable floor space below.

Caractéristiques clés & Avantages

• 1. Cost-Effective Solution
  Due to its simpler design with only one main girder, this crane type requires less material and is more economical to manufacture and install compared to a double girder crane, offering excellent value for money.

• 2. Compact and Space-Saving Design
  The single girder structure has a lower headroom, making it perfect for facilities with height restrictions. This maximizes the usable lifting height under the hook.

• 3. Robust and Reliable Performance
  Built from high-quality steel, the main girder is designed to withstand rigorous use with minimal deflection. The entire structure ensures stable and reliable operation over a long service life.

• 4. Easy Installation and Low Maintenance
  The simple design translates to easier and faster installation. With fewer components than more complex cranes, maintenance is straightforward, and operational downtime is reduced.

• 5. Smooth and Precise Operation
  Equipped with high-quality electric hoists and driven end carriages, these cranes provide smooth travel, precise load positioning, and quiet operation, enhancing workplace safety and efficiency.

• 6. Caractéristiques de sécurité améliorées
  Standard safety equipment includes overload limit switches, end limit switches for both bridge and hoist travel, emergency stop buttons, and thermal protection for motors, ensuring a secure working environment.

• 7. Options de personnalisation
  While a standard product, these cranes can be customized with various hoist capacities, spans, lifting speeds, and control options (pendant control or radio remote control) to meet specific application needs.

Application Cases

Single Girder EOT Cranes are workhorses across numerous industries:

• 1. Manufacturing Workshops: For moving raw materials, components, and finished products between machining, assembly, and storage areas.
• 2. Warehouses and Storage Facilities: Loading and unloading goods from trucks and transporting them to storage racks.
• 3. Assembly Lines: Positioning heavy parts and assemblies with precision during the manufacturing process.
• 4. Centrales électriques & Substations: Handling equipment like transformers, turbines, and generators for maintenance and installation.
• 5. Automotive Repair Shops: Lifting engines, vehicle bodies, and other heavy assemblies.
• 6. Small Steel Fabrication Units: Handling steel plates, sections, and fabricated structures.

EOT Crane Manufacturing Process

FAQ: Single Girder EOT Crane

Q1: What is the main difference between a Single Girder and a Double Girder EOT Crane?

UN: A Single Girder crane has one main beam supporting the hoist, which runs on the bottom flange. A Double Girder has two main beams, with the hoist running between them on a top-mounted trolley. Double girder cranes are used for heavier capacities (>20T), require higher headroom, and are more expensive but offer greater hook height.

Q2: Can the crane be used outdoors?

UN: Yes, but it requires specific modifications. An outdoor crane would typically be supplied with an IP54 or higher protection rating, anti-corrosion paint, and other features like wind hooks to secure it when not in use.

Q3: How is the crane powered?

UN: The most common method is via a festoon system or conductor bars that run along the runway, providing continuous power to the crane. Alternatively, cable reels can be used.

Q4: What maintenance is required?

UN: Regular maintenance includes visual inspections, checking for wear on wheels and brakes, ensuring electrical components are functional, and lubricating moving parts. An annual professional inspection is highly recommended.

Q5: Can I increase the capacity of my existing Single Girder crane later?

UN: No. Cranes are designed and built for a specific maximum capacity. Attempting to exceed this rating is extremely dangerous. The entire structure, including the girder, end carriages, and hoist, is rated for the original capacity.

Q6: How do I choose the right capacity and span?

UN: You must know the maximum weight of the loads you will be lifting and the exact distance between the runway support columns in your facility. It is always advisable to consult with our engineering team to ensure a safe and optimal design.
