Hoist Driving DeviceThe SC type construction hoist transmission mechanism, also known as the elevator drive plate, serves as the core component of the elevator’s drive system and safety device. It consists of a YZZl32M 4 special motor, a plane enveloping ring surface worm gear reducer, and safety components mounted on the same base.
Installed inside the elevator car, it is composed of a motor and speed reducer that drives the power plant to the small gear reducer output side. This then engages with the vertical rack and pinion, allowing the elevator to move smoothly upward. The safety device, which also uses the vertical rack and pinion for engagement, automatically activates in case of motor brake failure, ensuring an immediate emergency stop and enhancing operational safety.The compact design is optimized for efficiency, and all units undergo running-in tests before delivery. Available in single and double drive configurations, we can also supply single-motor reducers upon request.Hoist Driving Device (Single):Motor: rated power 11 kW, rated speed 1400 rpm, braking torque 120 N·m. Reducer (Single): ratio 14 (16), rated output torque 890 (1020) N·m, rated speed 100 (87) rpm, efficiency 85%. Safety device: brake load rating 30 kN, rated speed 1.2 m/s, braking distance 0.15–1.40 m. Note: gear reducer and bracket specifications are customizable based on user requirements.
Construction Hoist Driving Device Spare Parts
The driving device of the SC-type construction hoist is also called the elevator drive plate, serving as the core of both the drive and safety system. We provide a wide range of spare parts for most brands of construction hoists, including pinion, gear rack, counter wheels, rollers, SAJ safety devices, motors, reducers, drive mechanisms, electrical components, and more.
Our hoist driving devices support payload capacities up to 10,000 kg, lifting speeds up to 96 m/min, and installation heights reaching 450 meters. Our products are widely used in buildings, power plants, mining operations, oil fields, and chemical industries.
Construction hoist parts include:
Gear Rack; Safety Device; Motor; Drive Mechanism; Gearbox; Coupling; Gear; Brake Plate; Winch Machine; Hoist Mechanism; Limit Switch; Rollers; Overload Indicator and Sensor;
Specification:
Â
1. The SC series construction lifts use a rack and pinion system for material lifting;
2. These lifts have no counterweight, making them easy to dismantle and safe to operate;
3. They feature an overload limiter and mechanical chain device for reliable safety, with the SAJ40-1.2 model being a top choice for preventing cage falls;
4. The system uses three motors and three sets of reduction gears for smooth operation;
5. The electrical control system is simple, easy to maintain, and has a low failure rate;
6. Mast sections are painted four times, and galvanized options are available;
7. Variable-frequency models offer smooth and safe operation;
8. Starting current is lower than operating current;
9. Floor calling systems are available at extra cost;
10. Quick-wear parts are free, and the main mechanism comes with a one-year warranty.
