Width reel, every amplitude-changing drum can be rotated independently.2500t crane ship cable drum is using Lebus reel (as schemed
1), rope groove 8 is mainly spliced by two straight lines and two fold line grooves, compared to other smooth reels and oblique line rope groove drum,
Lebus reel have wind submissive, row's rope is close neat, without rope winding jib, Winding Layer it is more (3 layers of common reel hereinafter,
Lebus reel can achieve 10 layers) the advantages that.
What 2500t crane ship wirerope was selected is facial-contracted wire rope, with that contact area is big, rub resistance ability is strong is excellent
Point.But there is also certain problems：Since arrangement is close, Winding Layer is more, its steel wire of internal layer rope is caused to be pressurized very big,
And due to the presence of reel fold line grooves, wirerope has the appearance of the case where point contact compression in broken line, and the face of counteracting connects

=280113kg, 17 yuan/kg of unit price, therefore, wirerope buying expenses 280113kg*17 member/ten thousand yuan of kg=476 or so), it orders goods
Period is up to half a year.
2, required tooling device is more：Relevant tooling device includes crane barge, tugboat, truck crane, large-scale hoist engine, rope closing volume
The various ancillary equipments such as cylinder, haulage vehicle.
3, place occupancy is more, difficulty of construction is big：Cantilever crane is transferred to ground, occupies port berth, construction operation place is compared
Greatly, and it is relevant operation and require relatively high.
4, construction personnel is more, and required labour cost is high.
5, long construction period：Only replace variable-amplitude steel wire rope, it is necessary to nearly 25 to 30 days durations.
