--- Pricing Factors for Traction Machines ---
• Key Components Influencing Pricing:
The pricing of traction machines is influenced by several critical factors, starting with the type of motor technology used. Our permanent magnet synchronous gearless traction machines—such as the MINI2, MINI5F, and WTYF420 series—command higher prices due to their superior energy efficiency, reduced wear, and longer lifespan compared to traditional geared models. These machines incorporate rare-earth magnets and advanced magnetic circuit designs, which increase material costs but significantly lower long-term operational expenses. The maximum shaft load capacity is another major determinant; for instance, the MINI8F (5,500kg) or WTYF420 (20,000kg) models are priced higher than the VILLA125B (1,800kg) due to larger frame sizes, heavier materials, and enhanced braking systems. The number of poles in the motor also affects cost—higher pole counts (e.g., 32 poles in MINI8C) improve torque density and low-speed performance, justifying premium pricing. Additionally, customization plays a key role: non-standard rope specifications, notch angles, or special protection classes (e.g., IP54 in WTYF420) add to the final quote. The inclusion of IoT integration, such as the HD-EIOT platform, further increases value and price, especially when paired with cloud-based analytics and remote servicing. Manufacturing complexity is another factor—our digital workshops, equipped with SR20/1700 robots and CNC punching machines, allow for high-precision assembly, but require substantial investment in automation and quality control systems. Despite these costs, our economies of scale and vertically integrated production—spanning from raw material processing to final testing—enable us to maintain competitive pricing. For example, our MINI6C series, widely used in mid-rise residential buildings, offers excellent cost-performance balance, making it one of the most popular models globally. Ultimately, pricing reflects not just the upfront cost, but the total lifecycle value: energy savings, reduced maintenance, and extended service life.
• Comparative Analysis of Pricing in the Market:
When comparing traction machine pricing in the global market, Ningbo Xinda (Group) Co., Ltd. stands out for delivering premium quality at competitive rates. While European and Japanese manufacturers often charge 20–30% more for similar models (e.g., Schindler or Hitachi), our domestic R&D and localized supply chain enable us to reduce overheads without compromising performance. For example, a standard 1,600kg, 2.5 m/s gearless traction machine from a leading brand may cost $12,000–$15,000, whereas our MINI5C model with identical specs is available for around $8,500, thanks to our in-house production of rotors, stators, and control cabinets. Our investment in over 60 million yuan in advanced machinery—including PE800 hobbing machines and HNC35S worm grinders—ensures consistent precision and reduces defect rates, lowering warranty and repair costs for end-users. Moreover, our 97 domestic patents and 1 EU invention patent allow us to innovate faster and avoid licensing fees, which are common among foreign competitors. A comparative case study from Indonesia’s SSK 2 Pekanbaru Airport project illustrates this advantage: we provided 10 high-speed elevators with 3.0 m/s speed and 1,600 kg capacity at 18% below the initial bid from a European supplier, while still meeting all CE and ISO9001 standards. Similarly, in Mexico, our pricing strategy enabled us to win contracts for multiple MR-area projects despite strong competition from Fujitec and Mitsubishi. We also offer flexible payment terms and volume discounts for OEM partners, such as Guangri Elevator and SJEC, who integrate our traction machines into their complete elevator systems.
