Abstract

A split winch band shaft fast rotating device is provided herein. The device is disposed at the band shaft extension end at one side of the winch mount, and includes a band shaft joint and a rotator. At least one crowbar hole is set on the rotator. The rotator is coupled to one side of the band shaft joint with a unidirectional linkage mechanism set at the contact surface thereof. The band shaft extension end has at least one pin hole. The band shaft joint could be inserted into or covered on the band shaft extension end with a detachable connection mechanism arranged therebetween which could make the joint fixedly connected to the extension end by inserting one or more axle pins into the pin holes. The split winch band shaft fast rotating device is low in cost, convenient in maintenance, flexible in operation, and could improve the bundling speed of the winch.
