Engineered for Excellence in Heavy-Duty Applications

Weihha EOT crane gearboxes are not just components; they are precision power transmission systems built to handle the rigorous demands of:

• 1. High starting torque for lifting heavy loads smoothly.

• 2. Frequent start-stop cycles inherent in crane operation.

• 3. Variable speeds and precise positioning control.

• 4. Exposure to dust, moisture, and temperature fluctuations.

Key Features & Advantages of Weihua EOT Crane Gearboxes

• 1. Robust Construction & Premium Materials: Manufactured using high-strength alloy steels for gears and shafts, housed in rigid, high-grade cast iron or welded steel casings. This ensures exceptional resistance to shock loads, bending moments, and wear.

• 2. Advanced Helical / Hardened Helical Gearing: Our standard helical gear design provides smoother, quieter operation and higher torque transmission efficiency compared to spur gears. For ultimate durability in extreme conditions, Weihua offers hardened and ground helical gears, significantly increasing surface hardness and lifespan.

• 3. Optimized Power Transmission & Efficiency: Precisely engineered tooth profiles and meticulous manufacturing minimize power loss, translating to lower energy consumption and reduced operating costs over the crane’s lifetime.

• 4. Superior Sealing & Lubrication: Multi-layered sealing systems (lip seals, labyrinth seals) effectively prevent lubricant leakage and ingress of contaminants. Optimized lubrication channels ensure all critical components are adequately lubricated, even under heavy loads and inclines.

• 5. High Reliability & Extended Service Life: Rigorous quality control, advanced design simulation (FEA), and stringent testing protocols guarantee exceptional reliability. Weihua gearboxes are built for longevity, minimizing unplanned downtime and maintenance costs.

• 6. Smooth & Quiet Operation: The helical gear design combined with precision machining results in significantly reduced vibration and noise levels, contributing to a better working environment.

• 7. Comprehensive Safety Integration: Designed as a critical safety component, our gearboxes contribute to the overall safe operation of the crane, ensuring controlled motion and load handling under all specified conditions.

• 8. Standard Compliance: Designed and manufactured to meet or exceed international standards relevant to crane safety and performance (such as ISO, Nữ, TỪ, CMAA, AS).

• 9. Extensive Customization: Weihua understands that every application is unique. We offer customized EOT crane gearbox solutions tailored to specific requirements, including:

  • Various reduction ratios

  • Multiple mounting configurations (foot-mounted, flange-mounted)

  • Input/output shaft sizes and types

  • Specific torque and power ratings

  • Integration with different motor types (e.g., AC induction, variable frequency drive compatible)
