Key features

Zero-Servo Safety: Holds full load in air or lowers at controlled speed if brake fails, preventing hook slips.

High Torque Stability: 0Hz/150% steady output of rated torque ensures stable operation during start, lift, and lower.

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

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

Over-speed Protection: Identifies speed and braking abnormalities timely to prevent excessive speed parking or running.

Customizable Control: Supports customized input modes, driving modes, frequency control range, and reference power supply.

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.

Product Q&A

Q:What is the zero-servo function?

With an encoder connected, the inverter can drive the motor to hold the full load in the air or lower it at a controlled low speed when the brake fails, providing additional protection for lifting equipment.

Q:How does the drive handle voltage drops?

It features a wide voltage input range with automatic voltage stabilization, ensuring it can still meet torque output requirements even when the power grid voltage drops.

Q:What protection is provided against over-speed?

With an encoder connected, the inverter provides protection against parking or running at excessive speeds, identifying abnormalities in speed and braking power to prevent hook slips.

Q:What is the overload capacity of the heavy-duty type?

The heavy-duty type has an overload capacity of 150% rated current for 60 seconds and 180% rated current for 10 seconds.

Q:What are the available driving modes?

The drive supports V/F control (VVF), Speed sensorless vector control (SVC), and Speed sensor vector control (FVC).
