20/10 Ton Double Girder Overhead Crane Technical Parameters

Below are the standard technical parameters of 20/10 ton double girder overhead crane with electric hoist; customized parameters are available according to customer site requirements.

Core Product Features

1. Dual-hook Dual-working Design, Strong Versatility

Equipped with 20-ton main hook and 10-ton auxiliary hook, the crane can independently complete heavy-load main lifting and light-load auxiliary lifting operations. The auxiliary hook can assist in flipping, positioning and fine-tuning heavy workpieces, solving the problem of single hook’s low precision in auxiliary operation. It can switch working modes freely to meet diverse lifting demands of different weight materials, greatly improving operation flexibility and construction efficiency.

2. Robust Structural Design, Durable and Stable

The main beam adopts optimized box-type double girder structure, made of high-quality Q235B/Q355B high-strength steel plates. The whole machine features high rigidity, good stability and strong anti-deformation ability, which can withstand long-term high-frequency heavy-duty operation without structural fatigue and deformation. All welding seams adopt automatic submerged arc welding technology, with 100% non-destructive flaw detection to ensure welding quality and overall structural safety, realizing long service life and low failure rate.

3. High-precision & Efficient Operation System

Matched with high-performance electric wire rope hoist, the crane features stable lifting, low noise and small impact. Optional variable frequency speed regulation (VFD) system realizes stepless speed adjustment for lifting, trolley travelling and crane travelling, effectively avoiding workpiece shaking and positioning deviation. The operation is smooth and accurate, which greatly improves the safety and precision of high-precision equipment installation and material handling.

4. Complete Safety Protection Configuration

The crane is equipped with full-range safety protection devices, including overload limiter, height limit switch, travel limit switch, emergency stop device, phase sequence protection, over-current and over-heat protection. The double brake system ensures reliable braking under heavy load and emergency conditions. All electrical components adopt international famous brands, with IP55 protection level, adapting to harsh industrial environments such as dust and humidity, effectively eliminating potential safety hazards.

5. Energy-saving & Low Maintenance Cost

The optimized mechanical structure reduces the dead weight of the whole machine and operating energy consumption. The electric hoist has compact structure, flexible transmission and low wear of wearing parts. The modular design of electrical and mechanical components facilitates daily inspection, disassembly and replacement, greatly reducing later maintenance time and operation cost, with high cost performance.

Industry Applications

The 20/10 ton double girder overhead crane with electric hoist is suitable for medium and heavy-duty material handling scenarios in various industrial fields, covering indoor standard workshops and semi-open industrial sites:

• Mechanical Manufacturing Industry: Lifting and transferring of large mechanical parts, machine tool equipment assembly, finished product loading and unloading, and workshop material turnover.
• Metallurgy & Steel Industry: Handling of steel coils, steel plates and heavy metal raw materials, auxiliary operations for smelting and processing equipment.
• Construction & Engineering Industry: Lifting of engineering machinery accessories, building heavy components, and on-site auxiliary construction operations.
• Energy & Power Industry: Installation and maintenance of power station equipment, wind power accessories, electrical equipment and heavy pipeline handling.
• Warehouse & Logistics Industry: Stacking, handling and container auxiliary loading and unloading of heavy goods in large industrial warehouses and freight yards.
• Machinery Processing & Heavy Factory: Long-term cyclic lifting of heavy workpieces, mold handling and production line auxiliary handling operations.

FAQ: 20/10 Ton Double Girder Overhead Crane

Q1: What is the difference between the main hook and auxiliary hook of this crane?

A1: The 20-ton main hook is used for heavy-load main lifting operations with stable bearing capacity and strong load resistance, suitable for lifting large and heavy materials. The 10-ton auxiliary hook is mainly used for light-load lifting, workpiece flipping, fine positioning and auxiliary correction operations. The two hooks can work independently without mutual interference, improving the diversity and accuracy of on-site operations.

Q2: Can the crane adapt to customized working conditions?

A2: Yes. We support full customized services, including non-standard span, lifting height, working grade, operation mode and voltage configuration. We can also equip with explosion-proof, anti-corrosion and high-temperature resistant devices according to special working conditions such as explosion-proof workshops, high-temperature metallurgy and humid environments to meet personalized industrial needs.

Q3: What operation modes are optional for the crane?

A3: Three mainstream operation modes are available: handheld wired handle control (simple and cost-effective), wireless remote control (flexible and long-distance operation), and driver’s cabin control (suitable for long-time continuous heavy-duty work, with wide vision and more stable operation). Customers can select according to on-site operation habits and working intensity.

Q4: What safety protection devices does the crane have?

A4: The crane is equipped with a complete safety protection system: overload protection to prevent overloading operation damage, upper and lower height limit switches to avoid hook collision, travel limit switches to prevent over-running of crane and trolley, emergency stop button for sudden power-off and accident response, as well as phase sequence, over-current and over-heat electrical protection to ensure safe and stable operation in all working states.

Q5: What is the service life and daily maintenance of the crane?

A5: Under standard working conditions and regular maintenance, the whole machine has a service life of more than 15 years. Daily maintenance is simple: regularly check the lubrication of transmission parts, the tightness of connecting bolts, the sensitivity of brake and safety devices, and the integrity of electrical lines. The modular design greatly reduces maintenance difficulty and downtime loss.

Q6: Is the product compliant with international safety standards?

All our 20/10 ton double girder overhead cranes are manufactured in strict accordance with ISO international standards and national industrial crane specifications. The whole machine has passed strict quality inspection and load test, with reliable structural safety and stable performance, meeting the safety production requirements of domestic and foreign industrial enterprises.
