• 2. Estructura robusta de doble viga: The double girder design provides exceptional load-bearing capacity and stability. Compared to puentes grúa monorraíl, the 25-ton explosion-proof double girder model can handle heavier loads with less deflection, making it suitable for the 25-ton lifting requirement. The girders are typically made of high-strength steel, after precise welding and heat treatment to enhance durability.
• 3. Alta eficiencia de elevación: Equipped with a powerful hoisting mechanism, this crane offers smooth and efficient lifting operations. It has adjustable lifting speeds to meet different working needs, whether for precise positioning of heavy equipment or rapid lifting of materials. The trolley and bridge running mechanisms are also designed for low noise and stable movement.
• 4. Comprehensive Safety System: In addition to explosion-proof features, the crane is equipped with multiple safety devices, including overload protectors, interruptores de límite para altura de elevación y recorrido del carro, botones de parada de emergencia, y dispositivos anticolisión. These safety measures work together to prevent accidents and protect both the equipment and the operators.

Overhead Crane Installation Process for 25-ton Explosion-proof Double Girder Model

• 1. Pre-installation Preparation: Before starting the installation, conduct a detailed site survey to ensure the workshop meets the crane’s installation requirements, such as the height of the factory building, the strength of the crane runway beams, and the layout of the site. Prepare all installation tools, equipo (such as cranes for lifting components), and materials. Also, check the delivery of the crane components to ensure all parts are complete and undamaged, and verify the technical documents and drawings.
• 2. Installation of Crane Runway: Primero, install the crane runway beams on the factory columns or steel structure supports. Ensure the runway beams are level, aligned, and have the correct spacing. Use shims to adjust the levelness and tighten the connecting bolts firmly. Check the elevation and span of the runway beams according to the design requirements to lay a solid foundation for the subsequent crane installation.
• 3. Assembly of Main Girder and End Carriages: Assemble the main girders and end carriages on the ground. Connect the end carriages to both ends of the main girders using high-strength bolts, ensuring the connection is tight and accurate. Check the squareness of the crane frame and the parallelism of the two main girders. Install the trolley and hoisting mechanism on the main girders after the frame assembly is completed.
• 4. Lifting the Crane Assembly: Use a large-tonnage truck crane or gantry crane to lift the assembled crane frame. During the lifting process, use multiple lifting points to ensure the crane is balanced and avoid tilting. Slowly lift the crane to the height of the runway beams and accurately place it on the runway wheels. Ensure the wheels are properly aligned with the runway tracks.
• 5. Installation of Electrical System: Install the electrical cables, control cabinets, and operating devices. Connect the electrical components according to the electrical schematic diagram, paying special attention to the explosion-proof connections to ensure no sparks can leak. Test the electrical system to check if the motors, interruptores de límite, and control buttons work normally.
• 6. Commissioning and Inspection: After the mechanical and electrical installation is completed, conduct a comprehensive commissioning. Test the lifting, encapotado, viaje en carro, and bridge travel functions of the crane. Check the operation of the safety devices, such as the overload protector and emergency stop button. Adjust the parameters to meet the design requirements. Finally, invite relevant authorities to conduct an inspection and obtain the installation qualification certificate before putting the crane into use.

Important Considerations for 25-ton Explosion-proof Double Girder Overhead Crane Installation

• 1. Protection of Explosion-proof Components: When handling and installing explosion-proof components, avoid collision, impacto, or damage to the explosion-proof surfaces. Do not disassemble the explosion-proof components without authorization. After installation, check the explosion-proof seals to ensure they are intact and meet the explosion-proof requirements.
• 2. Compliance with Standards: The installation must comply with relevant national and industry standards, such as the explosion-proof safety standards for electrical equipment in hazardous areas and the installation technical specifications for puentes grúa. Keep detailed installation records, including the inspection results of each step, to facilitate future maintenance and inspection.
• 3. Adaptación ambiental: Consider the environmental conditions of the installation site, such as temperature, humedad, and corrosiveness. Take corresponding protective measures, such as anti-corrosion treatment for the crane structure in humid or corrosive environments, to ensure the crane’s service life.
