Core Product Advantages

1. High Structural Stability & Durability

Adopting optimized box girder welded structure and high-strength steel materials, the 12.5-ton overhead crane features low dead weight, high rigidity, and strong anti-deformation capability. The overall structure undergoes strict stress testing and anti-fatigue processing, effectively resisting vibration and impact during long-term continuous operation. With a professional anti-corrosion paint process, it adapts to harsh working environments such as dust, humidity, and mild chemical corrosion, extending the service life of the whole machine.

2. Energy-Saving & Low-Noise Operation

Equipped with high-efficiency low-power-consumption motors and variable frequency drive systems, the crane reduces energy consumption by 20%-30% compared with traditional ordinary cranes. The optimized transmission mechanism and silent running design lower operating noise significantly, fully complying with modern industrial environmental protection and noise control standards. The motor features a 60% continuous working rate and excellent heat dissipation performance, with a 30% higher cooling efficiency than conventional crane motors, avoiding overheating failure during high-frequency operation.

3. Flexible & Precise Control

Supporting multiple control modes including pendant control, wireless remote control, and cabin control, the crane realizes flexible and convenient operation. The variable frequency speed regulation system ensures smooth start, stop, and speed transition, eliminating cargo shaking and positioning deviation. It achieves accurate micro-positioning of heavy loads, greatly improving the precision and efficiency of material handling, assembly, and maintenance operations.

4. Low Maintenance & High Cost Performance

The whole machine adopts standardized and modular component design, with highly versatile spare parts and simple daily maintenance. Key electrical and mechanical components are selected from international first-class brands, with stable performance and low failure rate. The reasonable structural layout reduces later maintenance difficulty and operating costs, bringing long-term stable economic benefits for enterprise production.

Detailed Technical Specifications

Main Structural Composition

1. Main Girder & End Carriage

The main girder adopts integral welded box beam structure with optimized mechanical design, featuring high strength, light self-weight, and strong load-bearing capacity. The end carriage is made of thickened steel plate and precision-processed, matching with high-quality walking wheels to ensure stable traveling and no deviation during long-distance operation.

2. Electric Wire Rope Hoist

Equipped with CD1/MD1 type heavy-duty wire rope hoist, the core lifting component features compact structure, strong overload resistance, and stable lifting performance. The dual-speed lifting design meets the needs of fast handling and precise positioning, suitable for diverse working conditions.

3. Drive & Control System

Adopting brand frequency conversion drive motors and reducer devices, the transmission system runs smoothly with low wear. The electrical control system is equipped with integrated circuit protection modules, with sensitive response and stable control performance, effectively avoiding electrical faults caused by voltage fluctuation and overload.

Comprehensive Safety Protection System

This 12.5-ton overhead crane is equipped with a full set of safety protection devices to ensure zero-risk operation:

• ◆ Overload Limiter: Automatically cut off the lifting power when exceeding the rated load to prevent overload operation and equipment damage.
• ◆ Upper & Lower Limit Switches: Effectively prevent the hoist from over-traveling, avoiding collision and mechanical failure.
• ◆ Emergency Stop Device: Instantly cut off all power supply in case of abnormal conditions to ensure personnel and equipment safety.
• ◆ Phase Sequence & Overvoltage/Undervoltage Protection: Prevent motor burnout and system failure caused by power supply abnormalities.
• ◆ Rain & Dust Proof Protection: IP55 protection grade ensures stable operation in dusty, humid, and open indoor environments.
• ◆ Over-temperature Protection: Automatically stop operation when the motor temperature exceeds the threshold to avoid burning damage.
