Hoist / Elevator Reducer

Performance Characteristics
High Torque Density and Compact Transmission Structure: Through planetary gear or worm gear splitting design, it provides 30%-50% higher torque output than standard reducers within the same volume, making it especially suitable for narrow spaces such as elevator shafts or machine rooms.
Precise Speed ​​Control and Smooth Operation: Precision grinding technology combined with optimized tooth profile allows backlash to be controlled within ≤1 arc minute (precision type), ensuring no vibration during car start-up, stopping, and leveling, with noise levels below 65dB, improving passenger comfort.
High Safety and Reliability: Integrated mechanical overload protection (such as torque limiter) and reverse self-locking function (worm gear type) prevent overload slippage; the brake meets safety standards (such as 125% rated load braking capacity), ensuring safe stopping of the car in the event of a sudden power outage.
High efficiency and energy saving: The multi-tooth meshing design of worm gears or planetary gears reduces friction loss, achieving a transmission efficiency of over 95% (up to 98% for permanent magnet synchronous gearless systems), reducing energy consumption by 30%-40% compared to traditional asynchronous motors.
Long lifespan and low maintenance requirements: Gears are made of carburized and quenched alloy steel, and the housing is a cast iron or cast steel welded structure, with a design life exceeding 100,000 hours; sealed bearings and a centralized lubrication system reduce maintenance frequency and are suitable for continuous operation under high loads.

Technical configuration and adaptability:
Reducer types: Includes worm gear reducers (strong self-locking, suitable for low-speed elevators), planetary gear reducers (high torque density, used in high-speed elevators), and helical gear reducers (smooth and low noise).
Speed ​​ratio range: Single-stage speed ratios cover 5:1 to 60:1, and multi-stage combinations can reach 200:1, adapting to different lifting speed requirements (e.g., 0.3-4.0 m/s elevators).
Installation Method: Supports horizontal or vertical installation, flange connection or direct integration with traction machine units, adaptable to the compact layout of machine-room-less elevators.
Environmental Adaptability: Operating temperature -40℃ to 45℃, protection rating up to IP65, resistant to construction site dust and humidity fluctuations.
