6.3T Single Girder Overhead Crane for Metal Fabrication

Explore our case study on a 6.3T single girder overhead crane designed for metal fabrication. Discover challenges, and solutions in this project.

Industry Background

The customer operates in the precision metal fabrication industry. Their facility handles various processes, including metal cutting, welding, and assembly of structural components. As part of their workflow, they needed a lifting solution to transport metal sheets, finished assemblies, and semi-finished products across different workstations. Before implementing the new overhead crane, the company relied on a combination of manual lifting systems and outdated overhead cranes that did not consistently meet their operational requirements. The need to upgrade material handling equipment became essential as production volumes increased and the complexity of tasks grew.

Customer's Requirements and Challenges

1. Efficient Lifting Solution Due to increasing production demands, the customer needed a lifting system that could handle heavy loads efficiently while reducing labor dependency.
2. Space Constraints and Layout Optimization The facility had limited floor space, which meant the lifting equipment had to be compact and efficiently designed. The customer needed a solution that could operate within the existing infrastructure without requiring major structural modifications.
3. Safety and Compliance Requirements Occupational safety regulations required the company to minimize risks associated with manual handling. Their previous system posed ergonomic challenges and increased the likelihood of workplace injuries.
4. Reliability and Maintenance Concerns The customer wanted to buy a new crane because the old one had broken down while lifting heavy loads, resulting in a long downtime. Therefore, they sought a crane with low maintenance requirements and a long operational lifespan.
5. Precise Material Handling Accuracy in load positioning was required to facilitate automated assembly lines and reduce manual handling errors.

Problems with Previous Equipment

The lifting equipment that the customer was currently using had been in use for many years and was not functioning properly if they were lifting heavier components, which was causing a lot of inconvenience to their production.

These problems directly affected productivity and worker safety, prompting the company to seek a modern solution that could resolve these issues.

1. Frequent Equipment Downtime: The existing cranes and manual lifting systems often experienced operational delays due to frequent breakdowns and maintenance requirements.
2. Lack of Precision: Inconsistent load positioning led to inefficiencies in the assembly process, with errors that required rework and additional labor.
3. Inadequate Lifting Capacity: The older systems were not capable of safely handling the heavy components required in modern production, leading to safety concerns and limited lifting loads.

Why the Customer Chose Us

After researching various lifting solutions, the customer chose our 6.3T single girder overhead crane for several reasons:

• Proven Performance: Our crane systems have been successfully implemented in similar industrial applications.
• Customization Options: We provided tailored configurations to fit their existing layout and operational needs.
• Competitive Pricing: The cost-effectiveness of our solution made it a viable investment.
• Technical Support and Service: Our after-sales support, including installation guidance and maintenance training, reassured the customer.

How the 6.3T Single Girder Overhead Crane Solved Their Problems

1. Increased Efficiency in Material Handling

Considering that our customers need to transport components to a specific location for assembly, we produce them with precise positioning in mind, a feature that reduces the time required for cranes to move sheet metal and process parts.

2. Space-Saving Design

The compact single girder design allowed installation within the existing facility without major modifications. The crane operates above and is not affected by obstacles on the ground.

3. Improved Workplace Safety

Crane operation safety is a factor that must be considered in both our design and production, and the cranes we offer are equipped with features such as overload protection, emergency stops, and collision avoidance systems that reduce the risk of problems occurring during the operation of the equipment.

4. Low Maintenance and High Durability

The customer reported fewer operational disruptions due to the crane's reliable motor and robust construction. The system required minimal maintenance, resulting in lower long-term costs.

Customer Feedback and Results

After many months of use, the customer told us that their material handling speed is significantly faster and the crane has been running very well with no downtime problems. If they have other needs in the future, they will be happy to continue to cooperate with Yuantai.
