Threaded Lifting Loop For Concrete Elements Fitted With Threaded Lifting Anchors

The Threaded Lifting Loop for Concrete Elements is a high-strength lifting device designed specifically for precast concrete and heavy loads. Made from durable steel wire, it is pressed and galvanized to ensure excellent corrosion resistance and long-term reliability. Its versatile design allows seamless compatibility with female anchors featuring Rd or M threads, providing a safe, efficient, and dependable lifting solution for construction and industrial projects.

- Lifting heavy loads: Threaded Lifting Loop is mainly used for lifting and moving precast concrete parts to ensure safety and reliability during construction and transportation.

- Connecting Lifting Equipment: It serves as a lifting equipment connected to hooks or other lifting tools to provide a stable lifting point.

- Economical: Compared to other lifting equipment, the Threaded Lifting Loop is a cost-effective solution for most field operations.

- Re-usable: With no damage ensured, the Threaded Lifting Loop can be re-used, reducing costs over the long term.

- Easy to install: it can be quickly fitted to pre-fabricated components and fits a wide range of threaded lifting sockets of all sizes.

The product label plays an important role on the Threaded Lifting Loop and includes the following information:

- Maximum Working Load (WLL): indicates the safe working load for this lifting loop, ensuring that the user will not overload the lifting loop during use.

- Thread Size: Ensures that the lifting loop is compatible with the lifting socket.

- Serial Number: For tracking and quality control purposes and to facilitate periodic inspection and record keeping.

- Maximum Working Load: Ensure that this limit is not exceeded during use.

- Instructions for use: Know the applicable lifting angle and conditions of use to ensure safety.

Threaded Lifting Loops For lifting and transport concrete elements fitted with threaded lifting anchors

The Threaded Lifting Loop is typically compatible with the following accessories:

- Threaded Lifting Sockets: such as Rd or metric threaded sockets to ensure a perfect fit between the lifting loop and the socket.

- Hook: Attaches to the hook for lifting operations.

- Pressure Plate: In some cases, the use of a pressure plate can increase the stability of the lift.

1. BS1290:1983
This standard specifies the Working Load Limit (WLL) for wire rope lifting loops and determines the safe working load based on the minimum breaking load of the wire rope. A safety factor of 5:1 is normally recommended, and in some cases a safety factor of 6:1 can be provided.

2. LOLER (Lifting Operations and Lifting Equipment Regulations)

This is a UK regulation that sets out the safety requirements for lifting operations and equipment. It requires all lifting equipment, including lifting rings, to be regularly inspected and maintained to ensure its safety and reliability.

3. Instructions for use

- The lifting ring must be fully screwed into the threaded socket of the lifting anchor to ensure a secure connection.
- The lifting ring should only be attached to the unit after the concrete has reached a strength of 15 N/mm².
- The lifting angle should be less than 45°, if this angle is exceeded other types of lifting equipment should be used, e.g. lifting rings with pressure plates.

Security Enhancement Perspective of Thread Lifting Loop

4. Inspection requirements
 

The condition of the lifting loops shall be checked regularly. According to the standard DIN 3088 thelifting loop is not to be used shall one of the following faults be detected:

● 4 ruptures of wire at the distance the length of which is equal to three diameters of wire

● 6 ruptures of wire at the distance the length of which is equal to six diameters of wire

● 16 ruptures of wire at the distance the length of which is equal to thirty diameters of wire

● braiding rupture, deformation caused by pressure

● bended parts or swells at the bends

● thread damage at the wire chunk

● obvious wear, corrosive damage and other visible defects

These standards and specifications ensure safety and effectiveness when using the Thread Lifting Loop for lifting operations in a wide range of industries, including construction and manufacturing.
