Project: The electromagnetic double girder overhead crane, as a highly efficient and flexible material handling equipment, is widely used in industries such as steel, machinery manufacturing, energy, and logistics. It is particularly suitable for applications requiring frequent handling of magnetic materials. This project aims to design, manufacture, and provide a high-performance, safe, and reliable electromagnetic double girder overhead crane to meet customer material handling needs in complex working environments.
Working Environment: The crane is designed for indoor or sheltered outdoor environments, capable of withstanding certain temperature variations, humidity, and dust. It is particularly suitable for locations with electromagnetic interference and frequent heavy lifting. The operating temperature range is typically from -20°C to +40°C, with relative humidity not exceeding 90% (non-condensing).
Structural Composition: The electromagnetic double girder overhead crane mainly consists of a bridge frame, operator's cab, traveling mechanism, hoisting mechanism, trolley traveling mechanism, and electromagnetic control system.
Design Requirements: The structural design must consider strength, stiffness, stability, and durability to ensure safe operation under various working conditions. Additionally, it should be easy to maintain, operate, and adapt well to the environment.
Referenced Standards: This project complies with relevant domestic and international standards and specifications, including GB/T 14405 "General Purpose Overhead Cranes," JB/T 1306 "Electric Single Girder Cranes," and ISO/IEC 17025 "General Requirements for the Competence of Testing and Calibration Laboratories."
Manufacturing Materials: High-strength low-alloy steel (such as Q345B) is primarily used as the main structural material to ensure the equipment's load-bearing capacity and service life. Electrical components are selected from well-known domestic and international brands to guarantee system stability and reliability.
Lifting Capacity: Ranging from 5 tons to several hundred tons, customizable according to customer requirements.
Span: Typically ranging from 10 meters to 35 meters, customizable based on site conditions.
Lifting Height: Standard lifting height ranges from 6 meters to 20 meters, with higher options available for special requirements.
Operating Speeds:
Power Supply: Three-phase AC 380V, 50Hz.
Bridge Girder: Double girder structure with horizontal connections between the main girders to enhance overall stability.
Operator's Cab: Fully enclosed structure equipped with air conditioning, dustproofing, and vibration damping facilities to ensure operator comfort and safety.
Trolley Traveling Mechanism: Driven by variable frequency speed control motors, coupled with reducers and wheel sets for smooth operation.
Hoisting Mechanism: Utilizes electromagnets or electric hoists as the lifting power source, equipped with overload protection devices.
Crab Traveling Mechanism: Also employs variable frequency speed control to ensure precise positioning.
Hook Block: Forged from high-strength alloy steel, equipped with anti-drop devices.
Couplings and Drive Shafts: Utilize elastic pin couplings, with drive shafts made of high-quality carbon steel to ensure transmission efficiency and stability.
Drum Assemblies: Precision machined with surface hardening treatment to improve wear resistance.
Wire Ropes: High strength, low elongation, compliant with GB/T 8918 standards.
Wheel Assemblies: Cast iron or forged wheels with heavy-duty bearings to ensure smooth operation.
Power supply and power supply mode: Three-phase four-wire power supply is adopted, with main circuit and control circuit, equipped with short circuit and overload protection.
Electrical control scheme: PLC programmable controller is the core to realize automatic control, friendly operation interface, support fault diagnosis and remote monitoring.
Electromagnet: High-performance rare earth permanent magnet or electromagnet, providing strong suction, adapting to ferromagnetic objects of different materials.
Magnetic protection device: Ensure that the electromagnet slowly releases the load when the power is off to avoid impact.
Equipped with a trolley refueling pump, it is convenient for the key parts to be lubricated regularly.
The lubrication point is reasonably designed to facilitate the operator to complete the lubrication operation quickly and accurately.
Installation: On-site installation is carried out by a professional team to ensure that the equipment installation accuracy meets the design requirements.
Acceptance: No-load and load tests are carried out in accordance with GB/T 10183 "Tolerances for the manufacture and track installation of bridge and gantry cranes" and related standards to ensure that the equipment performance meets the standards.
The design and manufacturing are in full compliance with national and international standards.
ISO9001 quality system control ensures that the quality of each link is traceable.
The main performance parameters are within the standard range and are superior to similar products.
The raw materials and purchased parts are all high-quality brands at home and abroad. The structural parts have been strictly treated with anti-corrosion, with a smooth surface and precise dimensions.
Provide 24-hour technical support and respond quickly to customer needs.
Free equipment operation and maintenance training for user operators.
