رافعة حبل الأسلاك الكهربائية

يتكون جوهر رافعة حبل الأسلاك الكهربائية من محرك, آلية تقليل, a drum, a wire rope and a control system. It realizes the vertical lifting and horizontal movement of heavy objects through electric drive. Electric wire repe hoist has the characteristics of convenient operation, strong load capacity and high safety. It is an indispensable mechanized tool in modern lifting operations.

According to whether the electric wire rope hoist has an operating mechanism and the type of operating mechanism, it is divided into: fixed electric hoist, single beam trolley electric hoist and double beam trolley الرافعة الكهربائية.

Electric hoists without operating mechanisms and for fixed use can be divided into two types: support type and suspension type according to different installation methods.

The main components of the electric wire rope hoist are: traveling mechanism, محرك, transmission mechanism, drum and wire rope.

Product features of electric wire rope hoist

• High efficiency and energy saving: Using rare earth permanent magnet motor or variable frequency control technology, it has low energy consumption, smooth start and stop, and supports precise speed regulation;
• Safe and reliable: Equipped with dual braking system (electromagnetic braking + mechanical braking), overload protection device and limit switch, which can effectively prevent the wire rope from overwinding or overloading;
• Strong durability: The drum and pulley of the electric wire rope hoist are made of alloy steel with surface hardening treatment, which is wear-resistant and impact-resistant; the wire rope has been galvanized or plastic-coated, and has a long anti-corrosion life;
• تصميم وحدات: compact structure, easy installation and maintenance, the electric wire rope hoist can be used alone or matched with the gantry and driving track;
• السيطرة الذكية: supports wireless remote control, PLC integrated control, and can be equipped with sensors to achieve real-time load monitoring and fault diagnosis.

Application fields of electric wire rope hoist

• Manufacturing industry: workpiece lifting in automobile assembly lines and mechanical processing workshops;
• Construction industry: steel structure installation, building material handling and aerial work assistance;
• Warehousing and logistics: warehouse cargo stacking, container loading and unloading;
• Energy field: power plant equipment maintenance, wind power tower maintenance;
• Port terminal: small cargo hoisting and ship maintenance;
• Special environment: Explosion-proof electric hoist is suitable for use in chemical industry, mining and other flammable and explosive places.

Advantages of electric wire rope hoist

• 1. Improve operating efficiency: Compared with manual hoists, electric drives significantly reduce labor and time costs;
• 2. Strong adaptability: The electric wire rope hoist can operate stably in complex environments such as high temperature, high humidity, and dust;
• 3. Flexible operation: supports multiple control methods such as ground handle, remote control or automation system;
• 4. Low noise: The gear transmission structure is optimized, the operating noise is less than 75dB, and it meets environmental protection requirements.

Disadvantages of electric wire rope hoist

• 1. Depends on electricity: cannot be used when there is a power outage or unstable voltage, and needs backup power supply;
• 2. Maintenance costs are high: electric wire rope hoists require regular lubrication, wire rope wear and electrical component status checks;
• 3. Installation restrictions: It needs to be equipped with fixed rails or brackets, and there are certain requirements for the site’s carrying capacity.

Selection suggestions

• Light scenario (0.5-2 طن): Recommended permanent magnet motor + variable frequency control, suitable for precision assembly and workshop logistics;
• Heavy-duty scenarios (more than 10 طن): preferably double brake + alloy steel reel, suitable for construction and port hoisting;
• Special environment: Choose explosion-proof or IP65 high protection models for use in chemical industry and outdoor humid environments.

Electric wire rope hoist has become one of the core equipment in the field of industrial lifting due to its high load, high safety and flexible control. Although there are certain maintenance and installation thresholds, it has significant advantages in improving operating efficiency and reducing labor intensity, and is suitable for the handling needs of medium and heavy materials in many industries. Users can choose the appropriate model according to specific working conditions and pay attention to daily maintenance to extend the life of the equipment.
