I am selling 20 pieces of used runways as good as new. 11.5 m pitch. Used welded box runways. The power supply line can also be purchased. ### Operating Principle of Overhead Crane Runways Runways are the structures on which overhead cranes (or bridge cranes) move horizontally within a work area. They are essential for the efficient and safe movement of the overhead crane, and their operation is crucial to ensuring that the load is moved precisely and smoothly. **1. **Composition of Runways:** - **Rails or Tracks:** Runways consist of rails or tracks on which the wheels of the overhead crane run. These tracks are mounted above a fixed support structure, such as beams or columns. - **Supports and Fixings:** The rails are supported by brackets and supports that hold them in place and securely fasten them to the upper structure. - **Sliding Trolleys:** The trolleys mounted on the overhead crane move along the rails. These trolleys are equipped with rolling wheels or bearings that reduce friction and facilitate the movement of the overhead crane. **2. **Operating Principle:** - **Horizontal Movement:** The overhead crane moves horizontally along the runway rails. This movement is possible thanks to the action of the trolleys sliding on the rails. - **Load Sustainability:** The runways must be designed to support the weight of the overhead crane and the load it carries. Their strength and stability are essential to avoid deformation or malfunction. - **Alignment and Precision:** The rails must be installed precisely to ensure that the overhead crane moves smoothly and without deviation. Improper alignment can cause premature wear and malfunction. ### How to Use 1. **Installation:** - **Rail Mounting:** The rails must be mounted on fixed supports, following the design specifications and the manufacturer's instructions. Make sure the rails are perfectly aligned and level. - **Alignment Check:** Check that the rails are correctly aligned and that there are no distortions or irregularities in the travel path. 2. **Use:** - **Crane Movement:** Turn on the crane and use the control panel to move it along the runways. Make sure the movement is smooth and unobstructed. - **Loading and Unloading:** When lifting and moving loads, monitor the operation of the crane to ensure the load is moved safely and without swaying. 3. **Maintenance:** - **Regular Inspection:** Periodically check the runways for wear on the rails and trolleys. Look for signs of wear, damage, or misalignment. - **Lubrication:** Lubricate trolley wheels and moving parts of the runway according to the manufacturer's recommendations to reduce friction and extend service life. - **Cleaning:** Keep the rails free of debris and materials that could interfere with the movement of the overhead crane. ### When to Buy Used Runways 1. **Need to Upgrade or Replace:** If existing runways are damaged or no longer suitable for the needs of your operation, purchasing used runways can be a cost-effective solution to upgrade or replace the equipment. 2. **Budget Optimization:** If the budget for new purchases is limited, used runways can offer a more economical option without compromising the quality of the overhead crane's movement. 3. **Space and Time:** In some situations, purchasing used runways can allow for quicker implementation than purchasing and delivering new equipment, reducing downtime. ### Why Buy Used Tracks? 1. **Cost Savings:** Used tracks can be significantly less expensive than new models. This savings is beneficial for companies on limited budgets or looking to reduce costs. 2. **Reliability:** Tracks, if properly maintained, can provide reliable performance for many years. Many used models can still have a long service life if in good condition. 3. **Brand Quality:** Tracks from reputable brands, even used ones, can offer excellent performance and long life, as they are designed to withstand demanding working conditions. 4. **Testing and Inspection:** Many used track dealers perform testing and inspections to ensure that the rails are in good condition and ready for use. This helps minimize the risk of unexpected problems. 5. **Availability** Used crane runways can be available immediately, allowing you to implement or repair your overhead crane system without long waits for new runways to be manufactured and delivered. In short, purchasing used crane runways can be a cost-effective option for companies needing to upgrade or replace their overhead crane system. By ensuring you purchase from reputable sources and carefully inspect the condition of the equipment, you can get an excellent, cost-effective solution without compromising the quality and safety of your lifting system.
