US 11,660,478 B1 · Wireline traversal device

Abstract

A wireline traversal device may include an outer housing having a longitudinal slot, and an inner housing rotatably disposed within the outer housing. The inner housing includes a helical slot, a forward end of which is aligned with the longitudinal slot in the outer housing when the inner housing is in a home position. A forward end cap having a longitudinal slot and an inclined engagement surface is attached to a forward end of the outer housing. The longitudinal slot on the outer housing is aligned with the longitudinal slot on the forward end cap. At least two bearing members are rotatably disposed within the outer housing, with one bearing member attached to each end of the inner housing. The wireline traversal device may be used in a variety of applications in connection with a wireline, such as a zip line or safety line.
