📍 Project Background
A Brazilian hydropower plant client procured 2 units of QE double trolley double girder overhead cranes for heavy-duty lifting operations. The equipment required double trolley configuration with independent winch systems, fully customizable parameters, and suitability for humid operating conditions near the power plant site.
Suncan Crane provided a customized double trolley overhead crane solution, designed with lifting capacities of 40+15t and 40+10t. The equipment was engineered with robust anti-corrosion protection to suit Brazil’s humid environment, and all performance parameters comply with hydropower construction specifications.
🎯 Core Procurement Requirements
- Lifting operations: Must meet heavy-duty lifting conditions of a hydropower plant with double trolley configuration for smooth and reliable operation
- Parameter customization: Lifting capacity, span, lifting height to be customized per project requirements. Operating speeds coordinated with on-site lifting cycles. Control system must ensure ease of operation, flexibility, and precise control
- Environmental adaptation: Equipment must be suitable for Brazilian hydropower plant conditions with strong resistance to corrosion and moisture. Key components such as motors must meet required protection ratings to prevent moisture ingress
⚙️ Customized Solution
① Double Winch Trolley Design
- Heavy-duty winch trolleys: Each crane equipped with two independently operating winch trolleys, providing higher load-bearing capacity suitable for heavy-duty hydropower working conditions
- Auxiliary trolley for turning: The auxiliary trolley can be used for turning operations during component assembly processes
- VFD smooth control: Both hoisting and traveling mechanisms equipped with variable frequency drive, ensuring smooth start-up and braking without impact, with precise positioning capability
- Modular maintenance design: Motor, reducer, and brake in separate modular layout, allowing individual servicing without disassembling the entire mechanism
- Dedicated maintenance platform: Wire rope drum with independent support design, dedicated maintenance platform for safe inspection, and independent brake unit with automatic compensation and manual release functions
② Technical Parameters Customization
- Dimensional parameters: Span 12.8m, lifting height 12m, dual lifting capacities of 40+15t and 40+10t
- Electrical system: Designed per local power supply standards for direct grid connection and stable power operation
- Dual-mode control: Pendant control + remote control, ensuring operational convenience and flexibility for different working scenarios
③ Anti-Corrosion Design for Humid Conditions
- Steel plate treatment: Sa2.5-grade shot blasting, effectively removing surface oxide layers and impurities for strong coating adhesion
- Anti-corrosion coating system: Epoxy zinc-rich primer + chlorinated rubber topcoat, offering superior corrosion resistance for humid environments
- High protection motors: IP54 protection rating with Class F insulation, effectively preventing dust and water vapor ingress, ensuring stable operation in humid hydropower environments
✅ Delivery Results
- Production and shipment of 2 customized QE double trolley overhead cranes completed efficiently
- Operational efficiency and safety performance fully met project expectations. A5 duty classification well suited to hydropower working conditions
- Anti-corrosion system and IP54-rated motors enable reliable equipment operation in humid environments
- The client highly recognized the customized design, product quality, and manufacturing workmanship
