Professional Overview of High-Strength Lifting Loops for Reliable Heavy Lifting Operations

Definition

Lifting loops are an important accessory for lifting and handling heavy objects, especially precast concrete components. It is the most economical type of lifting loop, usually made of high-strength steel, with a flexible design, simple structure, easy operation, and suitable for a variety of lifting operations. The main function of the lifting loop is to provide a reliable connection point for cranes, hoists, or other mechanical equipment, thereby ensuring the safety and efficiency of the lifting process. They are widely used in construction sites, precast concrete manufacturing, heavy machinery handling, and other fields.

The design of the lifting loop takes into account multiple load angles so that it can be used in various working conditions and has strong adaptability. Especially when lifting large-scale precast concrete structures, the lifting loop, as an important part of the connection equipment, can ensure smooth and safe lifting.

HULK Metal's lifting loop

Material 

The main materials of lifting loops are high-strength alloy steel and carbon steel, which have excellent tensile strength and corrosion resistance and can maintain excellent performance in harsh working environments. Alloy steel has high wear resistance and oxidation resistance, and is suitable for environments that require high strength and long-term use. Carbon steel provides higher economic efficiency and is suitable for general load-lifting operations. According to the customer's use requirements, we also provide material customization services to ensure that the performance of each lifting loop can be highly matched with the customer's application scenario.

Five-fold safety factor

Lifting loops are designed with the risk of high loads in mind, so their performance adopts a five-fold safety factor to ensure safe use at five times the rated load. This safety design concept provides great protection for customers and can effectively prevent equipment failures or safety accidents caused by overload or improper use.

CE certification

HULK Metal's lifting loops are CE-certified and meet the safety and environmental standards of the European market. CE certification ensures the quality and reliability of our products and also allows customers to gain higher trust and recognition in the process of global use. Our lifting loops strictly follow international industry standards in the design and production process to ensure that each batch of products meets the requirements of high quality and high safety.

Advantages

As an economical and flexible lifting device, lifting loops have many significant advantages:

Suitable for different load angles

The lifting loops are designed with a load angle range of 0-45° in mind, which can cope with a variety of lifting angle requirements. Whether it is vertical lifting or slightly inclined lifting, the lifting loops can ensure the distribution of effective loads and the stability of lifting.

Economical and practical

As a relatively low-priced lifting tool, lifting loops have a cost advantage over other lifting devices. Due to its efficient structural design and easy manufacturing characteristics, lifting loops have become the preferred accessories in many large-scale lifting operations.

Easy size allocation

The size allocation of the lifting loop adopts a color coding system, which not only helps users easily identify the lifting loops of different specifications, but also improves efficiency and reduces the possibility of errors in busy lifting operations.

Thread type

The lifting loops provided by HULK Metal adopt a high-precision thread design, mainly Rd/M type. This thread type is compatible with metric and Rd standards, ensuring good compatibility with a variety of equipment and application scenarios. Its precision thread manufacturing process ensures the firmness and durability of the connection, meets industry standards, and undergoes strict quality control to meet the high requirements of customers.

High strength and durability

The wire of the lifting ring is made of high-strength steel, which ensures its reliability in long-term use. After professional heat treatment and surface treatment, the lifting ring can maintain high strength and durability in harsh working environments.

Safety performance

The safety of the lifting ring is one of the most important considerations in its design process. In order to ensure that there will be no safety hazards during the lifting process, the lifting ring must undergo a series of rigorous tests to ensure its excellent performance.

Fatigue test

The lifting ring undergoes long-term fatigue testing to simulate the stress conditions under long-term use. Through continuous fatigue loading tests, the lifting ring can withstand tens of thousands of lifting load cycles without deformation or breakage.

Alternating bending test

The lifting ring also needs to undergo an alternating bending test. This test is to verify the strength and durability of the lifting ring under repeated bending stress. The lifting ring must ensure that there is no permanent deformation after multiple bending to ensure its reliability in different working environments.

Tensile test

The tensile test of the lifting ring is also an important means of evaluating its performance. By simulating the tensile stress of the lifting ring during the lifting of heavy objects, it is ensured that it can withstand the specified tensile force value and will not have any cracks or breaks due to stretching.

Load angle test

The load-bearing capacity of the lifting ring at different load angles requires special testing. The lifting ring needs to maintain a high load-bearing capacity within the load angle range of 0-45° and ensure the smooth progress of the lifting operation.

Installation and use

The installation process of the lifting ring is relatively simple. Usually, the connecting end of the lifting ring only needs to be fixed to the lifting hole of the precast concrete component or other lifting object. During the installation process, it is necessary to ensure that the fixing point of the lifting ring is firm and reliable to avoid accidents. It is also necessary to pay attention to the selection of the load angle during installation to avoid exceeding the load capacity range of the lifting ring.

Installation steps

The installation steps of the lifting ring are as follows:

Determine the size and model of the lifting ring to ensure that it is suitable for the weight and size of the lifting object.

Check whether the surface of the lifting ring is intact and ensure that it is not corroded, cracked, or otherwise damaged.

Fix the connection end of the lifting loop to the lifting socket or lifting point to ensure that it is firmly fixed and avoid looseness.

Adjust the lifting angle to ensure that the load is within the load angle range of the lifting loop.

Precautions for use

Do not overload the lifting loop, and the maximum load capacity of the lifting loop must not exceed its design parameters. The load angle should be kept between 0-45° during lifting to avoid exceeding the safe angle range of the lifting loop.

Regularly check the condition of the lifting loop, especially its load point and connection part, to ensure that there is no damage or deformation.

During lifting operations, avoid collision between the lifting loop and other objects to avoid damage to the lifting loop.
