PURPOSE: A driving winch apparatus for constructing a suspension bridge cable with high-speed and low-speed rotary shafts is provided to improve the construction efficiency of a suspension bridge by facilitating the replacement of the apparatus. CONSTITUTION: A driving winch apparatus for constructing a suspension bridge cable with high-speed and low-speed rotary shafts comprises a drive rotary drum(11), a driven rotary drum(12), an intermediate rotary gear plate(21), and a drive motor(31). The drive rotary drum has a drum body(13), a drive rotary gear plate(14), a separation prevention member(15), and a high-speed drive shaft(16). The separation prevention member prevents a cable(2) from being separated from the drum body. The intermediate rotary gear plate is located between the drive rotary gear plate and a driven rotary gear plate of the driven rotary drum and has a low-speed drive shaft(22). The drive motor has a motor shaft(32) selectively connected to the high-speed drive shaft and the low-speed drive shaft. The drive motor selectively rotates the high-speed and low-speed drive shafts. |
