Title:
HANGING ROPE FEEDING DEVICE USED FOR LIFTING HEAVY LOAD
Document Type and Number:
Japanese Patent JP3903378
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To shorten the construction period by increasing the lifting speed of the hanger mounted to the tip of a plurality of PC strand cable at the time of non load.
SOLUTION: A drive roller 22 driven with a motor 25 with a reducer is installed through bearings 23a, 23b on a base frame 21. An eccentric roller 38 is mounted above the drive roller 22 so as to position in parallel, and so as to be made eccentric at the lower side of the upper frame 32. The eccentric roller 38 of the upper frame 32 side is made to be pressed to the drive roller 22 of the base frame 21 side, and a plurality of PC strand cable 2 held between the eccentric roller 38 and the drive roller 22, are securely delivered. If the drive roller 22 is rotated, the PC strand cable 2 is delivered at high speed, and the lifting speed of the hanger is increased at the time of non load.
