BASKET LIFT 731
Hybrid Cable Innovation: Dual-Voltage Architecture for Building Lifts
The FLEXIDRUM® BASKET LIFT 731 represents a revolutionary engineering approach to hoisting cables for building construction lifts. Unlike traditional single-voltage cables that require separate control and power conductors, the 731 integrates dual-voltage capability (300/500V control + 0.6/1kV power) into a single hybrid structure.
This hybrid design is specifically engineered for modern building hoist systems operating in construction environments, where:
Control circuits (300/500V) manage speed control, safety interlocks, load monitoring, and emergency descent systems
Power circuits (0.6/1kV) drive the main hoist motor (typically 15–50 kW capacity)
Single cable run simplifies installation—no separate routing for control vs. power, reducing labor costs ~30%
Space efficiency eliminates need for dual-cable management on building facades
Safety redundancy through separate insulation layers ensures control circuit failure doesn’t disable power monitoring
The BASKET LIFT 731’s architecture is distinctly different from port crane cables (SPREADER 740/750) and terrestrial industrial cables, reflecting the unique requirements of vertical construction lift systems where personnel safety depends on reliable signal transmission alongside high-power motor control.
