Abstract

The invention discloses a crane extension arm rotation device which comprises a body, wherein the top surface of the body is provided with a connector; the surface, opposite to the connector, is provided with a first connection rod and a second connection rod; the side surfaces of the body are provided with a first rotation shaft and a second rotation shaft; the body is made of high-intensity steel; and rotation outlets of the first rotation shaft and the second rotation shaft are made of smooth stainless steel. According to the crane extension arm rotation device, the body is made of the high-intensity steel, so that the safety is improved, and accidents are avoided; and the rotation outlets of the first rotation shaft and the second rotation shaft are made of the smooth stainless steel, so that friction force is reduced, and a shaft blocking phenomenon is avoided.

Description

technical field [0001] The present invention relates to a swivel device, more precisely, to a crane extension arm swivel device. Background technique [0002] Due to the large lifting capacity of the crane, the strength of the crane is extremely high, and the corner is the concentrated point of force, so the strength of the corner device is required to be higher. At the corner is the turning device, which requires wear-resistant materials for long-term use. Most of the existing rotating devices ignore these details, resulting in short service life and rapid depreciation. Contents of the invention [0003] The invention mainly solves the technical problems existing in the prior art, thereby providing a more reliable crane extension arm rotating device. [0004] Above-mentioned technical problem of the present invention is mainly solved by following technical scheme: [0005] A crane extension arm rotation device, comprising a body, a connection port is provided on the to...
