Compacted rope with double-compacted steel wire rope and manufacturing method of same

Abstract

The invention provides a double-compressed steel wire rope crimping sling, which includes a steel wire rope and a crimping noose, a rope loop is provided at the end of the rope body of the steel wire rope, and the crimping noose sets the connection between the rope loop and the rope body The part is sealed and pressed inside; the steel wire rope is a double-compacted steel wire rope with a breaking force coefficient of 0.46 or more and a strength grade of 2160MPA or more. The endless annular steel sleeve is tempered and forged twice at 400°C. The present invention also provides a method for making the above-mentioned rigging. The strength of the double-compacted steel wire rope crimping rigging produced by the method disclosed in the present invention can be consistent with the strength of the double-compacted steel wire rope adopted, and the processing process will not affect the Rigging strength has an effect. The carrying capacity of the rigging is increased by nearly 40% on the basis of ordinary pressed rigging.

Description

technical field [0001] The invention relates to the technical field of ropes, in particular to a double-compacted steel wire rope crimping sling and a manufacturing method thereof. Background technique [0002] At present, rigging has been widely used in metallurgy, lifting transportation, and construction industries, and has become an indispensable lifting necessity. The load-bearing strength of the rigging is an important indicator of the rigging. Most of the rigging on the market now uses aluminum alloy casings and ordinary round strands contacting steel wire ropes to make rigging. The load-bearing capacity is low, and the safety and reliability of hoisting cannot be guaranteed. , cannot fully meet the needs of actual use. Contents of the invention [0003] In view of this, it is necessary to provide a rigging with a stronger load-bearing capacity and a manufacturing method thereof. For this reason, the technical scheme that the present invention adopts is as follows:...
