Description

Production method of circular sling and circular sling Technical Field The invention belongs to the technical field of circular hanging strips, and particularly relates to a production method of a circular hanging strip and the circular hanging strip. Background The ring sling is a flexible sling widely applied in the field of hoisting, and consists of a protective sleeve and a bearing core, wherein the protective sleeve is a tubular belt formed by braiding, is sleeved outside the bearing core and is used for protecting the protective sleeve of the bearing core, and the bearing core is a rope loop which is formed by winding a plurality of wires with the same parent metal and connecting the tail ends of the wires, and is used as a main loaded part of the sling. The current production technology of bearing the weight of the core, mostly by two I-shaped wheels rotate the winding form, and such winding mode often appears winding irregularly, when the suspender receives the pulling force, the silk thread can not even atress, causes the silk thread low in utilization ratio, especially under the more circumstances of winding number of turns, this kind of condition is more serious, and because the unable uniformity of guaranteeing of winding at every turn also causes the quality stability of ring suspender poor, often can appear unqualified product in the inspection, this very big competitiveness that has influenced the product.
