Description
Technical field
This utility model relates to steel wire rope preload Technique field in crane hoisting operation, particularly a kind of steel wire rope pretension afterburner system.
Background technology
During crane job, steel wire rope needs to keep certain tension force during being entangled to elevator, with ensure steel wire rope in elevator neatly, be closely wound around.This afterburning to steel wire rope and be entangled to the process of elevator and be the work of steel wire rope pretension.
Steel wire rope pretension will be substantially improved wirerope-winding quality, reduce the abrasion between steel wire rope, prevent from dodging the bad phenomenon such as seam, rope skipping, final boom hoist cable service life.
In use there will be the bad phenomenon such as disorder cable, rope without the steel wire rope of pretension, the most then reduce service life of steel wire rope, heavy then cause steel wire rope or reel to damage, serious threat Hoisting Security.
In prior art, there are employing disk brake or magnetic powder brake to originate as the moment of resistance, and then realize steel wire rope pretension, but it still suffers from following defect.
Disk brake is applied to pretightning force afterburner system and has the disadvantage in that
