10-Ton QDX Double Girder Bridge Crane

Discover the capabilities of the 10-Ton QDX Double Girder Bridge Crane, designed for heavy lifting and enhanced efficiency in industrial applications. Explore its features and specifications today.

The QDX double girder bridge crane from Yuantai is a European‑style overhead crane designed to FEM standards, offering spans of 7.5m to 31.5m and lifting capacities from 5t to 100t, with light dead weight, minimal headroom and reduced hook‑to‑wall distance to maximize working space. Its box‑section steel girders, optimized for torsion resistance, carry a modular electric hoist or open winch trolley featuring a planetary gearbox, wire rope drum and hook block, all driven by three‑phase asynchronous motors with variable‑frequency drives for smooth acceleration and precise speed control. Safety is ensured by overload protection relays, hoist and travel limit switches, and end‑buffer shock absorbers, while control options include pendant stations, radio remotes and PLC management of acceleration, deceleration and motor safeguards. Maintenance is simplified via side‑walkways for component access, oil‑bath lubrication of gearboxes and wheel bearings, and modular electrical cabinets with remote diagnostics, making the QDX suitable for applications in steel mills, fabrication shops, warehouses, power plants and heavy‐duty industrial settings.

The Customer's Industry and Operational Environment

The customer in this case operates within the manufacturing sector, specifically in the production and assembly of large metal components for heavy machinery. This industry demands high lifting capacities, precise load handling, and the ability to operate in confined spaces or harsh conditions. Overhead cranes are indispensable in such environments, especially when tasks require handling bulky materials, such as steel beams and heavy machinery parts, with a high degree of accuracy.

Before adopting the 10-Ton QDX Double Girder Bridge Crane, the customer faced several challenges in their day-to-day operations. Their previous lifting equipment could not efficiently handle the weight or offer the precision needed for intricate tasks. Furthermore, there were frequent issues with crane stability and slow operation speeds, which led to production delays and safety concerns.

The Customer's Need

The primary need for the customer was to upgrade their lifting equipment to improve both operational efficiency and safety. Their existing cranes were either outdated or not suited for heavy-duty tasks, which resulted in frequent downtime and maintenance costs.

Key requirements for the new crane included:

A lifting capacity of at least 10 tons to handle the heavy loads typical in their operations.
Enhanced stability and smooth operation for precise load handling.
Durability to withstand challenging industrial environments, including high-temperature areas and heavy-duty applications.
Faster operational speeds to reduce cycle time and improve overall productivity.
Minimal maintenance requirements to ensure long-term reliability and cost-effectiveness.

The Challenges Faced Before Using the 10-Ton QDX Double Girder Bridge Crane

Before upgrading to the 10-Ton QDX Double Girder Bridge Crane, the customer encountered several persistent issues with their existing equipment:

Inadequate Load Capacity: The previous cranes could not handle the heavy and oversized components the customer routinely lifted. This led to manual lifting or using multiple cranes for a single load, both of which were inefficient and time-consuming.
Operational Slowness: The speed of load lifting and movement was too slow to keep up with the fast-paced production schedules. This delayed other stages of production, causing a backlog.
Unreliable Stability: The older cranes exhibited stability issues, especially under heavy loads. This posed a significant safety risk and disrupted operations when the crane failed to maintain proper control of the load.
Frequent Maintenance Needs: Due to the age and wear of their previous equipment, the customer faced continuous maintenance issues. This not only increased operational downtime but also escalated repair costs.
Limited Safety Features: The lack of advanced safety features on the older cranes made it challenging to ensure the safety of workers, particularly when handling materials in high-risk environments.

These challenges significantly hampered the customer's production efficiency, safety standards, and operational costs.
