Abstract:
PROBLEM TO BE SOLVED: To provide a cable traction device with which a large traction force is obtainable and which allows the passage of different diameter parts, such as junctures of a cable and a traction rope, without adjustment.
SOLUTION: This cable traction device is constituted by arranging a second cable delivery section 22 which is formed by winding an endless belt 27 stretched over freely rotatably arranged driven rollers 25 and idle rollers 26 below a first cable delivery section 12 in which a driving roller 17, a driven roller 18 and intermediate rollers 19 are freely rotatably arranged in an arc shape having a radius of curvature above the permissible radius of curvature of the cable and an endless belt 15 for driving is stretched thereon. The device is so constituted that the cable 20 is held between these two sections. The second cable delivery section 22 is constituted vertically movably and is kept pressed and energized perpendicularly upward by torsion coil springs 42.
