Key features

Zero-Servo Safety: Holds full load in air or lowers at controlled speed if brake fails, ensuring extra safety.

High Torque Stability: 0Hz/150% rated torque steady output ensures stable lifting, lowering, and starting.

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

Tower Crane Algorithm: Prevents shaking during slewing, reduces speed overshoot risk, and improves efficiency.

Over-speed Protection: Detects abnormal speed/braking power to prevent hook slips and excessive running.

Customization Options: Customization from Designs available; OEM and ODM services are supported.

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.
