Double Trolley Double Girder Overhead Crane

The application scenarios of double trolley double girder overhead crane include:

• Metallurgical industry: used for lifting and transporting raw materials and finished products in steel plants, non-ferrous metal smelters, mines, and other places.
• Shipbuilding: used for lifting and assembling large ship components in shipbuilding plants, docks, and other places.
• Mechanical processing: used for the handling and lifting of mechanical equipment and components in mechanical manufacturing plants, automobile manufacturing plants, engineering machinery manufacturing plants, and other places.
• Electric power industry: used for the installation and hoisting of large equipment and components in thermal power plants, hydropower stations, nuclear power plants, and other places.
• Chemical industry: used for the handling and lifting of heavy equipment and pipelines in chemical plants, petrochemical plants, and other places.
• Manufacturing: In automobile manufacturing plants, it is used to move components from one workstation to another.
• Port and Logistics: In the port and logistics industry, it is used for loading, unloading, and stacking goods, such as transferring containers from ships to ports, or sorting and storing goods in warehouses.
• Construction site: used for hoisting and installing building materials such as steel beams, concrete, etc.
• Mines and quarries: used for transporting and loading heavy ore or stone materials, capable of working in harsh environmental conditions, and meeting high-intensity material handling requirements.
• Factories, freight yards, warehouses: used for loading and unloading steel parts, steel, etc., suitable for lifting long materials (wood, cardboard boxes, pipe seals, rods) in workshops or open-air warehouses of factories and mining enterprises.

In summary, QE double beam bridge crane is widely used in various industrial fields and scenarios due to its multifunctionality and high efficiency, which can improve production efficiency and reduce labor costs.

The double trolley double girder overhead crane (referred to as QE type double beam bridge crane) has the following advantages:

• High homework efficiency: When it is necessary to lift two objects of different positions or specifications at the same time, two small cars can be used to operate them separately, saving time and space; When precise positioning of a long rectangular object is required, two small cars can be used in conjunction to improve positioning accuracy and safety; When it is necessary to lift a super long and overweight object, two small cars can be used to operate simultaneously, and the distance between the two hooks can be adjusted to balance the load distribution and reduce bending deformation.
• Reasonable structural design: Both the main and auxiliary trolleys adopt a closed box structure design and are equipped with windproof guide rails to prevent wind from affecting their stability. Both the main and auxiliary cars are equipped with electric hoists as lifting mechanisms. The large vehicle operating mechanism adopts variable frequency speed control to achieve smooth start and stop.
• The performance parameters have a wide range of applications: the rated load is generally 5~320 tons, the span is generally 10.5~31.5 meters, the lifting height is generally 6~18 meters, the working speed (large and small vehicle running speed and lifting speed) and working level are high, which can meet the needs of different working conditions.
• Strong adaptability: Suitable for lifting long materials (wood, paper rolls, pipe fittings, bar materials) that are not easy to package or bulk in workshops or open-air warehouses of factories and mines. It can also be used for loading and unloading steel loose parts at docks.
• High safety: Advanced variable frequency speed control system is adopted to achieve smooth start and stop, reducing impact and vibration. Has good universality and adaptability, can customize products with different specifications and parameters according to user needs.
