What Is a Lifting Clutch for T Anchors?
The lifting clutch for T anchors is a reusable lifting device used together with spherical head anchors or T anchors in precast concrete lifting systems. It connects the crane hook or lifting gear to the embedded anchor, allowing precast concrete elements to be lifted, turned, and positioned during production, transport, or installation.
The Type TH lifting clutch is commonly used in pin anchor lifting systems. When correctly matched with the anchor load group and installed in the proper lifting direction, it helps create a secure lifting connection for precast wall panels, beams, slabs, and other concrete units.

The capacity loads are axial with a breakage safety factor equal to 5 for all types of lifting clutches (1,3 tons up to 32 tons). The Spherical Head Lifting Clutch comes in 6 different load groups. 1,3 to 32 tons, to suit the load carrying a range of ALL TYPES OF LIFTING ANCHORS with spherical heads.
Instructions for the Use of Spherical Head Lifting Clutches
Lifting and Turning
The Spherical Head Lifting Clutch is constructed in a way that an unintended coupling off (even without tension by a lifting device) is impossible. On lifting, attention must be paid to the fact that the lip is in the direction of the tension being applied.
The Spherical Head Lifting Clutch is suitable for lifting in all directions (axial, diagonal, and lateral tension).
On the turning of units, special attention must be paid to the lip position of the Spherical Lifting Head Clutch. The lip must always be in the direction of the Tension (See picture 3).
What Materials Are The Lifting Clutch Made Of?
By Precision Casting and Forging, Donrex Precast produced CE certified lifting clutch (ring clutch) with a high-grade 35CrMoV special casting head clutch and forged bolt, to ensure stable quality and high performance. Super Cast Alloy Locking Ring. Lifting Ring is Forged Alloy Steel. 100% Crack Tested. Safety Factor 5:1Concrete Lifting Clutches have been exclusively designed and approved for use with Lifting Anchors.
They are available in a range of Working Load Limits. They have been designed so that they cannot spontaneously disengage whilst the system is under load at any orientation, provided they are connected to the head of the correct anchor in the recess. When the lift is complete and the load released, the clutch is quickly and simply disengaged.
Identification markings are required for the Lifting Eye to comply with AS 3850 - 2003. The Lifting Eye must be proof load tested every 12 months in accordance with AS 3850-2003. The Lifting Eye has a FOS (factor of safety) of no less than 5 in accordance with AS 3850 - 2003.

Releasing the Spherical Head Lifting Clutch:
To release the Spherical Head Lifting Clutch, the tension on the clutch must be removed. Thereafter, the Spherical Head Lifting Clutch can be released by turning the handle in the opposite direction to the lip
Corrosion Protection:
Corrosion protection can be increased by installing the Spherical Head Anchor in a sunken position. The recess former must be installed to ensure the functionality of the Spherical Head Anchor according to these installation instructions and must have the minimum dimensions in accordance.
Dimensions for Sunken Assembly:
The Spherical Head Lifting Clutch counts as a lifting device and is there for subject to regular inspection (at least once a year). This must be executed by an expert, and it is the responsibility of the user.
Particular safety procedures and regulations must be followed to extend the lifespan and durability of the Spherical Head Lifting Clutch. The right hook size and form should always be checked and ensured.
