Turnaround Sheaves

This allows for the grease injection control head to be pointing downwards instead of upwards.

Typically, the Turn-around sheave would be mounted on top of a tool catcher with a grease injection control head suspended from the other side.

Essentially a pressurised top block, the turn-around sheave consists of a sheave wheel held within a pressure retaining housing. By creating the assembly without a central hub, weight is kept to a minimum. The sheave is a precision-machined ring, which rotates on a large bearing to which grease can be pumped into for lubrication.

Turn-around sheaves can be supplied with any of the standard quick unions in order that it can be assembled directly to a suitably configured tool catcher and grease injection control head. If required, an alternative 2-inch 10-flowtube box connection can be provided on one side of the sheave body to eliminate a quick union.

Accessories available for the turn-around sheave include:

• Grease Injection Control Head Clamps

• Fixed Floor Blocks

• Grease Catchers

As with all Hunting PCE, great effort has been made to create a product that is rugged and reliable, whilst being as light and as user-friendly as possible. To achieve this, extensive use of Finite Element Analysis (FEA) has been used in the design.
