Characteristics of HD Type European Standard Single Girder Bridge Cranes

The features of HD Type European standard single girder overhead cranes are mainly reflected in the following aspects:

1. Scientific and Rigorous Design

Fatigue Strength-Based Design: The steel structure and mechanical systems are designed not only to meet maximum static load requirements but also by calculating stress cycle counts over the entire design service life, ensuring durability under frequent and high-intensity operations.

Modular Design: Standardized modular drive units (highly integrating motors, brakes, and gearboxes) are adopted, offering compact structure, high transmission efficiency, and ease of maintenance and replacement.

Clear Duty Classification: Internationally recognized FEM duty classes (e.g., A3, A4, A5) are used to precisely specify the crane's working capability, scientifically matching the actual usage frequency and load conditions of users.

2. Exceptional Performance

Smooth Operation and Precise Positioning: Frequency conversion stepless speed regulation technology (standard feature) is widely used, enabling soft starting and stopping of loads, significantly reducing operational impact and load sway, and facilitating precise positioning and assembly tasks.

Intelligent Control: With a PLC (Programmable Logic Controller) at the core, the system includes functions such as fault self-diagnosis, real-time monitoring (e.g., load weight, motor status), and data recording, offering high intelligence and ease of maintenance.

3. High Safety and Reliability

Redundant Safety Protection: Multiple safety devices are equipped, such as a dual braking system (service brake + safety brake), dual limit switches (operational limit + emergency limit), and overload limiters (automatically cutting off unsafe operations), constructing a comprehensive safety protection system.

High-Quality Core Components: Key parts (e.g., motors, brakes, electrical control systems, electrical components) generally use internationally renowned brands, ensuring reliability and long service life from the source.

4. Compact Structure and Lightweight Design

"Three Small" Features: Small end carriage dimensions, small wheelbase, and low overall height. This design maximizes the vertical space utilization of the workshop, provides greater effective lifting height, and reduces the wheel load on the workshop runway beams, potentially lowering civil engineering costs.

Excellent Anti-Corrosion Performance: The steel structure undergoes strict shot blasting and rust removal treatment, with multi-layer spraying of high-quality epoxy zinc-rich primer and polyurethane topcoat, offering strong corrosion resistance suitable for various harsh industrial environments.

5. Low Maintenance Costs

Thanks to its scientific design, high-quality components, and modular structure, the failure rate is extremely low.

Many components feature maintenance-free or low-maintenance designs (e.g., sealed bearings, disc brakes), significantly reducing daily maintenance workload and long-term operational costs.
