Key features

Zero-Servo Function: Holds full load in air or lowers at controlled speed when brake fails with encoder.

Wide Speed Control Range: 1:50 for VVF and 1:1000 for FVC to handle light load high speed and heavy load low speed.

Over-Speed Protection: Detects abnormal speed and braking power to prevent hook slips with encoder connection.

Special Brake Control Logic: Ensures safe operation and prolongs braking system life with reasonable time sequence.

Wide Voltage Input Range: Automatic voltage stabilization maintains torque output even during power grid voltage drops.

Tower Crane Slewing Algorithm: Prevents shaking and reduces speed overshoot risk during variable frequency slewing.

High Overload Capacity: 150% rated current for 60s and 180% for 10s (Heavy Duty); 200% for 3s (Super Heavy Duty).

OEM/ODM Customization: Customization from designs available with 150 R&D engineers and 6 production lines.

AI-Powered supplier vetting

SummaryThe supplier is explicitly identified as a professional technical supplier serving frequency-conversion governors, servo systems, industrial automation, and energy-saving systems. It provides 3D software design and design-based customization, and reported new products during the past year. Its operating resources include 6 production lines, 150 total years of R&D engineer experience, 21–30 quality-control staff, and 10 quality-assurance/control inspectors. Service processes include documented corrective and preventive actions, complaint handling, supplier assessment, and quality assurance. The supplier has inventory capability and valid manufacturing contracts, but no overseas warehouse, showroom, agent, or branch; overseas service coverage is limited to repair in Africa and South America. Financial records are referenced for 2022–2024, but their results are not provided. No certification information or customer cases are stated.

Supplier typeThe supplier is explicitly described as a professional technical supplier. Its stated business scope covers development, production, sales, and after-sales service for frequency-conversion governors, servo systems, industrial automation products, and automation or energy-saving systems.

After-Sales capabilityThe supplier states that after-sales service is within its business scope and has documented complaint-handling and corrective/preventive-action procedures. It also has inventory capability, 6 warehousing and logistics centers, 11 technical service departments, and repair services in Africa and South America, although it has no overseas warehouse, showroom, agent, or branch.

R&D capabilityThe supplier provides 3D software design services, has customization-from-design capability, reported new products during the past year, and has 150 total years of R&D engineer experience. These facts provide explicit evidence of ongoing technical and product-development capability.

Production capacityThe supplier operates 6 production lines, has 21–30 quality-control staff and 10 quality-assurance/control inspectors, maintains inventory capability, and has valid manufacturing contracts with related subcontractors. It also reports average peak- and off-season lead times within 15 working days, supporting a demonstrated production and fulfillment capability.

Customization capabilityCustomization from designs is explicitly stated as the design service capability, and the supplier provides 3D software design services. This directly supports its ability to develop customized designs rather than only standardized products.
