Cast Aluminum Wellhead Wireline Hay Pulley For Well Intervention

Wireline Pressure Control Wireline Hay Pulley

Ⅰ.Introduction

The Hay Pulley is used to control and manipulate the direction of the wireline or braided cable from a horizontalpositon to a vertical position en route to the stuffing box from the wireline unit. This tool is generally positioned at the wellhead on the lubricator to reduce side pull force and to avoid lateral loading of the lubricator during heavy jarring operations.

The Hay Pulley is used to control and manipulate the direction of the wireline from a horizontal positon to a vertical position en route to the stuffing box from the wireline unit. This tool is generally positioned

at the wellhead on the lubricator to reduce side pull force and to avoid lateral loading of the lubricator during heavy jarring operations.

The hay pulley is used to pull the wire or cable ( braided cable ) from the top of the lubricator to the drum surface of the  wire or cable, so that the tension point of the  wire or cable (braided cable ) is moved from the top to the production tree, thus reducing the tension load of the wire or cable (braided cable ) side and preventing the damage of the lubricator from being bent. The hay pulley

can also be lifted to change the direction of the load on the wire or cable (braided cable ).
