Crane Specifications

Crane Type and Features

The 10-ton overhead crane double girder is designed to meet the heavy-duty lifting needs of the precast concrete manufacturing plant. This crane type is equipped with a European-style low headroom electric hoist, providing both strength and efficiency for demanding tasks.

• Double Girder Design: This design enhances the crane's overall stability and lifting capacity, making it perfect for handling large, heavy concrete components. The two parallel girders provide increased support and minimize deflection under heavy loads.
• Low Headroom Electric Hoist: One of the key features of this crane is its low headroom electric hoist. This allows the crane to operate efficiently in environments where vertical space is limited. The reduced headroom ensures the crane can lift heavy loads without taking up excess overhead space, which is crucial for optimizing the plant’s production area.

By combining the double girder design with the low headroom hoist, the crane maximizes both lifting capacity and space efficiency, making it ideal for a precast concrete plant where both safety and space utilization are essential.

Capacity and Span

• Crane Capacity: The crane is designed with a 10-ton lifting capacity, which is perfectly tailored to the heavy lifting demands of the precast concrete industry. The 10-ton capacity allows the crane to handle large concrete beams, slabs, and other heavy components commonly found in the plant’s operations.
• Crane Span: The crane has a 20-meter span, which provides the reach needed to cover a wide area of the production floor. This span allows the crane to transport large loads from one end of the plant to the other without the need for excessive maneuvering.

Together, the 10-ton capacity and the 20-meter span ensure that the crane can efficiently handle both the weight and size of the precast concrete components. The combination of these two specifications allows the crane to optimize workflow, reducing the time spent on lifting and moving materials across the plant.

Design Considerations

The low headroom design is one of the most significant design considerations of the 10-ton overhead crane double girder. In a manufacturing plant, especially one with limited space, every inch of headroom counts. By reducing the space the crane needs overhead, the low headroom design makes the most of the available vertical space, enabling the crane to operate effectively in tight areas.

This design consideration is especially crucial in the precast concrete plant, where space is often constrained, and efficient use of every square meter is necessary to maintain a smooth production process.
