PCE Wireline Heavy Duty Knuckle Joint Wireline Tool String

Ⅰ.Introduction

A wireline heavy duty knuckle joint is a tool string accessory, used to provide flexibility within the wireline tool string. It is recommended to place a knuckle joint immediately below the rope socket when the rope socket does not offer rotation within the wireline .

II. General technical parameters:

Note: More customized parts are available upon request.

III. Structural features and use:

The upper contact and the inner ball socket of connecting sleeve constitute a marked inner spherical surface; the bottom of ball stud is connected with the lower contact. There is a spherical surface out of the connecting sleeve and a spherical surface in the lower contact. After assembly, all inner and outer spherical surfaces touch each other together.

While swinging and rotating the lower contact, the outer spherical surface of ball stud can move freely in the ball socket. Meanwhile, the inner spherical surface of lower contact touches the outer spherical surface of connecting sleeve and move synchronously. When the bearing force is upward, the spherical surface of lower contact bears the force to avoid that the bending caused by the ball stud bearing heavy load.
