Featuring SS 304 food-grade construction and a versatile geared motor/traction drive, it ensures reliable, hygienic, and precise operation in demanding environments like hotels, hospitals, and restaurants.
Quick Answer
The KONE Service-DW delivers precision leveling and smooth, low-noise operation for critical goods transfer, supported by its robust geared or traction drive system and integrated load balancing capabilities.
✓Technology: Advanced Geared Motor/Traction Drive System with Soft Start/Stop and Precision Leveling.
✓Safety: Certified to EN 81-3 / IS 14665, featuring Comprehensive Interlock System and Overload Sensor.
✓Durability: Constructed with SS 304 Food Grade Car Material, MS Structure, and Heavy Duty Rollers for sustained commercial use.
The 2023 KONE Service-DW is a powerhouse for hospitality and healthcare environments where hygiene is non-negotiable. Its SS 304 food-grade construction and efficient traction drive, hitting 0.50 m/s, make it superior for high-traffic restaurants and clinics. With a 300kg capacity and 20m reach, it handles multi-floor logistics with Finnish precision. You should buy this for reliable, heavy-duty commercial transport across up to 8 floors. Avoid it if you require a simple residential lift or specific safety features like an integrated emergency alarm.
✓ Who Should Buy
- •Hotels and Hospitality establishments requiring efficient room service, linen, or laundry transport.
- •Restaurants and Catering services needing rapid, hygienic transfer of food, dishes, and supplies between kitchen levels.
- •Hospitals and Healthcare facilities for moving medical supplies, patient meals, or lab samples.
- •Office buildings and Libraries for document, mail, or book transfer between floors.
- •Retail establishments and Warehouses for light stock movement or small parcel delivery.
✕ Who Should Avoid
- •Installations requiring passenger transport; this unit is strictly for goods.
- •Applications involving heavy industrial loads consistently exceeding 300kg.
- •Environments demanding continuous variable speed control, as this model features soft start/stop but not full variable speed.
- •Situations where comprehensive emergency lighting or emergency power backup for operation is a critical requirement.
Product Overview
The KONE Service-DW represents a pinnacle in commercial vertical transport, specifically designed as a high-performance dumbwaiter for efficient goods movement. Manufactured by KONE in Finland for the 2023 model year, this unit falls under the Service Series, targeting demanding environments such as hotels, restaurants, hospitals, and offices. It boasts a substantial load capacity range of 50-300kg, accommodating diverse requirements for light to medium-duty goods. The car, crafted from SS 304 food-grade stainless steel, ensures hygienic operation, making it ideal for food and medical transfers. Car dimensions are highly customizable, ranging from 600-1200mm in width and depth, and 800-1400mm in height.
Driving the Service-DW is a robust Geared Motor or Traction System, delivering operational speeds between 0.30-0.50 m/s with a power rating of 1.5-3.0 kW, available in both 230V and 415V configurations at 50Hz. This ensures consistent and energy-efficient performance across its maximum travel height of 20 meters, serving 2 to 8 floors. Access is managed via a Push Button Control Panel, complemented by a choice of Manual Swing or Vertical Bi-Parting doors. Key performance features include smooth and low-noise operation, soft start/stop functionality to protect sensitive loads, and precision leveling for accurate floor alignment. Safety is paramount, with built-in safety sensors, an overload sensor, an emergency stop, and a crucial interlock system. The load balancing system further enhances stability and operational efficiency, guaranteeing reliable goods transfer.

Engineering Analysis
The KONE Service-DW's engineering design prioritizes reliability, safety, and operational efficiency for commercial goods transfer. At its core, the selectable Geared Motor or Traction Drive System offers distinct advantages. The geared motor provides high torque at lower speeds, ideal for varying load conditions and stop-and-go operations characteristic of dumbwaiters. The traction system, conversely, offers smoother, quieter operation and can be more energy-efficient for higher travel heights within the 20-meter limit. Both systems, paired with a 1.5-3.0 kW power rating, are optimized for the 0.30-0.50 m/s speed range, ensuring rapid yet controlled vertical transport.
Precision Leveling is a critical performance feature, ensuring the car floor aligns perfectly with the landing, minimizing trip hazards and facilitating smooth loading/unloading of delicate or wheeled items. This is complemented by Soft Start/Stop functionality, which significantly reduces mechanical stress on the drive components and mitigates load shift, enhancing the longevity of the system and the integrity of transferred goods.
Safety Protocols are meticulously integrated, adhering to stringent EN 81-3 / IS 14665 standards. The Interlock System is foundational, ensuring that car movement only occurs when all landing doors are securely closed and that doors can only be opened when the car is precisely aligned at the landing. An Overload Sensor prevents operation beyond the rated 300kg capacity, protecting equipment from damage and ensuring structural integrity. Combined with Emergency Stop functionality and Load Overrun Protection, these systems provide a multi-layered safety net crucial for commercial environments.
Regarding Load Distribution and Structural Integrity, the KONE Service-DW features an SS 304 Food Grade Car Material, essential for hygienic applications in kitchens and hospitals, offering excellent corrosion resistance. The supporting MS Structure frame, coupled with Steel Guide Rails and Heavy Duty Rollers, ensures robust alignment and smooth travel. The inclusion of a Counterweight System significantly reduces the power required from the motor, improving energy efficiency and extending motor lifespan by balancing the car's weight. Furthermore, the Load Balancing System actively manages load distribution within the car, preventing tilting and ensuring stable transit. Installation mandates a Load Bearing RCC Shaft with specified pit and headroom dimensions, emphasizing the necessity of a structurally sound foundation for safe and reliable long-term operation.
