RMCS Precast Lifting Loops and Clutches

---

Threaded Lifting Loops can be used with all sizes of threaded inserts. They are the most economic lifting loops and are suitable for most applications. They are not suitable for turning/pitching. They may be reused subject to the inspection procedure, detailed below, but they are not recommended for severe reuse conditions. Threaded Lifting loops should only be attached to the unit after the concrete strength has reached 15 N/mm. In some cases it may be economical and practical to leave the loops attached to the unit, until final installation.

Threaded Lifting Loops are manufactured from high grade steel wire, swaged in a steel ferrule and finished with zinc plating. They are clearly marked with their SWL. The thread type is Rd/M, which is compatible with both metric and Rd inserts. Threaded Lifting Loops are suitable for use with inserts cast in flush with the face of the unit, or recessed by using the recess formers.

Lifting at an angle greater than 45 degrees is not allowed.

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 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 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 be in the direction of the Tension (See picture 3).

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 dimentions in accordance with table 2 here below.

Dimensions for sunken assembly

The Spherical Head Lifting Clutch counts as a lifting device and is therefor subject to regular inspection (at least once a year – BGR 600 Section 2.8). This must be executed by an expert and it is the responsability 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 be ensured.
