In mining, lifting heavy materials is just another day at work. Discover how our solutions help handle up to 20 tonnes of ore and equipment effortlessly!
In mining, handling heavy materials is daily business. The customer needed to lift up to 20 tonnes of ore, equipment parts, or maintenance materials. They work in tight facility spaces. They need precise load placement. They need high reliability to avoid downtime.
Understanding the Client's Lifting Requirements
The customer runs a vital repair workshop that aids Peruvian mining operations. Their regular tasks include assembling, maintaining, and repairing large mining machinery. Material handling is directly impacted by the particular and difficult issues this environment poses. The primary challenges and requirements included:
- Heavy-Load Capacity: The client regularly handles mining machinery components and fabricated structures weighing up to 20 tons. Their existing equipment lacked the necessary capacity and structural integrity for these heavy loads, creating a significant bottleneck in their production schedule.
- Precision Handling: The nature of equipment repair and assembly requires exact positioning of components. The crane needed to provide smooth and controlled movement in all directions to allow workers to align parts perfectly without risking damage to expensive equipment.
- Duty Cycle and Reliability: The workshop operates continuously. The crane required a high working class (A5-A7) to withstand intense, frequent use without failure. Customers want new cranes to be durable and reliable with less downtime.
- Spatial Constraints and Hook Height: The workshop, while large, required a crane that could maximize available hook travel. A low headroom design was advantageous for providing maximum lift height within the existing building structure, ensuring even the tallest components could be lifted clear of the floor.
- Harsh Industrial Environment: The crane needed to be built to perform reliably in an industrial setting with potential exposure to dust, temperature variations, and consistent heavy use. Durability and corrosion resistance were key selection factors.
These specific demands ruled out standard overhead cranes and necessitated a robust, high-performance solution engineered for heavy-duty industrial applications.

This crane has a compact design, beautiful appearance, and the electrical equipment is enclosed, the whole crane is reliable and durable, which is very suitable for the customer's application needs.
Why We Choose the QDX Crane
We selected the QDX European crane over conventional options for several compelling reasons that directly addressed the client's needs:
- Lightweight Design: The QDX crane is designed with advanced materials and structural optimization. Compared to traditional cranes, its dead weight is reduced by 15-30%, and maximum wheel pressure is reduced by 10-35%. As a result, the client's existing building structure would be under far less stress, negating the need for expensive and time-consuming facility reinforcements.
- Energy Efficiency: The crane uses significantly less energy because of its lightweight design and high-efficiency motors and drives. Given the crane's demanding duty cycle, this offers the client a significant operational cost savings.
- High Duty Cycle for Demanding Environments: Rated for working classes A5 to A7, the QDX crane is built for exactly the kind of continuous, severe operation found in mining maintenance workshops. This guarantees long-term reliability and reduced wear and tear.
- Compact and Space-Saving Design: The European design philosophy prioritizes a compact structure and low headroom. This provides maximum hook height and allows for better utilization of the workspace beneath the crane, which is crucial for maneuvering large mining equipment components.
Technical Design of the 20-Ton QDX Mining Crane
The structural components of the bridge cranes we offer are designed as follows:
1. Structural Components and Configuration
The crane uses a heavy-duty double-girder bridge made from box-section steel. It delivers high strength and minimal deflection when lifting 20-ton loads. A 20-ton crab trolley with a precision hoist, hard-tooth reducer, and VFD provides smooth, accurate lifting and lowering. Bridge and trolley travel use compact three-in-one drive units that combine motor, brake, and reducer for reliable motion. VFD soft starts and stops cut load swing and reduce mechanical stress.
2. Control Systems and Operational Flexibility
The crane offers two control options for different tasks. The primary method is a wireless radio remote that lets the operator move around the shop for better visibility and safety; it includes an emergency stop and an IP65 rating for dust and moisture protection. A wired pendant station serves as a secondary, tactile control with comparable safety features.
3. Advanced Safety and Protection Systems
Safety is the top priority for the QDX crane. It has overload protection to stop lifts above the 20-ton rating. Upper and lower limit switches prevent the hook from over-traveling. For sites with multiple cranes, wireless anti-collision devices can be fitted to avoid accidents. All electrical parts sit in IP55-rated cabinets to keep out dust and water. The crane draws power through a safety sliding contact line for reliable supply.

How the QDX Crane Meets Specific Mining Industry Lifting Needs
The 20 tons QDX crane we offer can perfectly meet the lifting needs of our clients.
1. Ensuring Workshop Productivity
The high duty cycle (A5-A7) means the crane can operate consistently throughout a shift without requiring cool-down periods or being a bottleneck. Reduced downtime for the mining equipment being serviced and higher workshop throughput are direct results of its dependability.
2. Enhancing Safety in a Hazardous Environment
The wireless remote control allows the operator to position themselves safely away from the load and out of pinch points, ensuring a clear view. The integrated safety systems (overload protection, limit switches) create multiple layers of protection against accidents caused by human error or mechanical failure.
3. Optimizing Energy Usage
Because of its energy-efficient drives and lightweight construction, the crane uses less electricity for each lifting action. This results in lower total operating costs and a less environmental impact for a client managing energy-intensive mining activities.
