Designed for Material Handling & Vertical Transport
The Kylift Construction Hoist Winch is a high-performance lifting and material transport device designed explicitly for the most rigorous structural environments. Whether hoisted vertically on high-rise scaffoldings or used for heavy horizontal pulling of mining equipment, the BTW series offers unmatched wear resistance and stable performance.
Built around a solid structural steel base frame, each unit integrates a specialized helical-bevel reduction gearbox, a robust hoist motor, and a heavy-duty mechanical brake system to guarantee complete control during operations.
Compact Structural Steel Frame
Welded steel plate chassis distributes stress evenly under maximum tension limits.
Helical Gear Reduction Box
Smooth tooth engagement, lower noise, and large lubricating oil reservoirs (up to 40L).
TJ2/YWZ Industrial Brakes
Automated spring-loaded electromagnetic drum brakes stop heavy loads securely.
Custom Control Solutions
Optional pendant controllers, wireless remotes, and Variable Frequency Drive (VFD) panels.

Heavy-Duty System Architecture
Each component of the BTW series is over-engineered to provide ultimate structural margin, keeping down-time at zero.
Y/YZR Cast Iron Motors
Premium asynchronous crane motors. Featuring Class F insulation and IP54/IP55 protection. Rated for high starting torque to handle instant vertical breakaway loads effortlessly.
Spring-Loaded Drum Brake
The TJ2 magnetic brake or YWZ hydraulic thruster brake locks automatically whenever power is disconnected. This prevents dynamic slippage, assuring optimal operator safety.
Helical Reduction Gears
The closed-loop multi-stage transmission gears run silently in oil. Machined to fine tolerances, they offer optimal mechanical torque transfer and require low maintenance.
Grooved Heavy Drum
Constructed from heavy-walled seamless steel pipe with heavy structural flanges. Reduces rope wear and ensures precise laying pattern during long rope winding operations.
