Motore a Frequenza Variabile

The variable frequency motor provides an energy-saving and high-performance drive solution for cranes.

As essential lifting parts, every heavy-duty power unit must comply with international material handling standards.

1. Smooth Speed Control

The adjustable speed drive works with frequency control systems. It achieves precise speed regulation from 0 to 100%.

2. Low Mechanical Wear

Soft start and controlled braking minimize structural stress. This effectively protects gears, pumps, and belt-driven components.

3. Efficient Heat Dissipation

Enhanced cooling using a dedicated external ventilator ensures stable operation. It extends the service life in harsh environments.

Industrial Variable Frequency Motor Manufacturing

Hanko Heavy Industry fabricates high-quality electrical machinery according to rigorous ISO standards.

Our engineering team delivers dependable power solutions for modern factories. To fully optimize your hoist traveling mechanism, we highly recommend matching these drives with our premium crane wheels.
