Lifting Capacity and Hook Configuration

The core strength of this overhead crane lies in its dual-hook setup. The main hook is rated at 50 tons, ready to handle your heaviest and most demanding loads. Meanwhile, the auxiliary hook, rated at 10 tons, offers added versatility for lighter lifts or load positioning.

This combination is designed specifically for heavy industries where flexibility and precision matter. It allows operators to switch between tasks quickly without needing to change equipment, saving time and improving workflow efficiency.

Why choose a dual-hook system?

• Load stability: Using the auxiliary hook can help balance loads during complex lifts or assist in carefully positioning heavy items.
• Maintenance lifting: The smaller hook is ideal for lifting equipment parts during crane maintenance or assembly line setups without interrupting main production lifts.
• Complex assembly: When working with multi-component loads, having two hooks lets you lift and maneuver parts independently or together, improving safety and precision.

This practical approach to lifting means your facility can handle a wider variety of tasks with fewer interruptions or equipment swaps, making the crane a real asset in your daily operations.

Available Span and Lifting Heights

When choosing an overhead crane, getting the right span and lifting height is just as important as selecting the lifting capacity. These dimensions determine how well the crane fits your workspace and how effectively it can handle your loads.

Span Options

The 50/10 ton overhead crane offers a range of standard spans from 10.5 meters up to 31.5 meters. This wide range allows the crane to fit small workshops as well as large industrial halls.

• Shorter spans (around 10.5 to 16.5 meters) work well for compact facilities with limited floor space.
• Longer spans (22.5 to 31.5 meters) are suitable for wider buildings, offering greater coverage and more flexibility in material handling.

Lifting Heights

Lifting height depends on the working duty class and the type of hook used:

• For the A5 duty design, the main hook lifts up to 10 meters, while the auxiliary hook reaches 12 meters.
• The A6 duty design—built for more frequent or intense operation—offers a higher lift: 16 meters for the main hook and 18 meters for the auxiliary.

Key Considerations for Span Selection

• Building width: The crane span should match the clear distance between runway rails inside your facility.
• Runway structure: Existing beams and supports may limit or determine your maximum span.
• Work process: Consider whether you need full coverage of the workspace or just partial span for specific tasks.
• Future expansion: If you anticipate growing operations, choosing a slightly longer span can save costly upgrades later.

Choosing the right span and lifting height ensures smooth crane operation without risking collisions or wasted space. In the next section, we'll cover lifting and travelling speeds to help you understand the crane's performance on the move.
