Frequently Asked Questions
Can container shears handle the same materials as gantry shears?
Container shears are excellent for most scrap materials up to 150mm thickness with 400-800T cutting force. However, gantry shears with 800-2000T force are specifically designed for thicker materials (up to 300mm) and heavier industrial scrap that container shears cannot effectively process.
Which offers better value for money - gantry or container shears?
Container shears typically offer better value for operations requiring flexibility and mobility, with 40-60% lower total costs including installation. Gantry shears provide superior value for high-volume, permanent operations processing heavy materials where their higher cutting force and capacity justify the increased investment.
How do processing speeds compare between the two technologies?
Gantry shears significantly outperform container shears in processing capacity, handling 150-220 tons/hour vs 15-45 tons/hour. This 3-5x capacity difference makes gantry shears ideal for high-volume operations, while container shears excel in flexibility and rapid deployment.
Can I upgrade from container to gantry shear as my operation grows?
Yes, many operations start with container shears for their flexibility and lower investment, then add gantry shears as volumes and material requirements increase. The container shear can be relocated or used for mobile operations while the gantry handles high-volume processing at the main facility.
Which is better for steel mill and shipyard applications?
Gantry shears are typically preferred for steel mills and shipyards due to their ability to handle thick steel plates, heavy mill scale, and massive ship hull sections. The 800-2000T cutting force and 300mm thickness capability make them essential for these heavy industrial applications.
