The importance of tension in lifting building accessories

With the continuous development of the modern construction industry, the scope of use of precast concrete components is expanding day by day, which puts forward higher requirements for hoisting operations. As a key operation link in the construction process, the safety and efficiency of hoisting directly affect the progress and quality of the entire project. Among them, the tension problem during hoisting is an important factor in ensuring the safety of the operation. Reasonable tension design, scientific testing, and high-performance accessories are the basis for smooth hoisting operations.

The core role of tension in hoisting

Security guarantee

Hoisting operations involve heavy-weight prefabricated parts. Improper tension design may cause the lifting device to fail or the component to fall, endangering the safety of construction personnel and equipment. The scientific calculation of pulling force can ensure that each hanging point is evenly stressed, thereby reducing the risk of accidents caused by overload.

Improvement of hoisting efficiency

Reasonable tension distribution can not only optimize the lifting path but also reduce the load pressure of construction equipment. For example, multi-point lifting technology can significantly improve operating efficiency and reduce lifting time by evenly distributing pulling force.

Integrity protection of components

Precast concrete elements generally have high strength, but their surfaces are still susceptible to excessive tensile forces. Optimizing the tensile force design can effectively avoid cracks or other forms of damage during the hoisting process and ensure the integrity of the components after hoisting.

Key factors affecting tensile design

precast weight and shape of concrete accessories

When hoisting, the weight and shape of precast concrete accessories have a direct impact on the tension distribution. Large or irregularly shaped components require more hanging points to balance the forces and avoid single-point overload.

Selection of lifting equipment

Hoisting equipment made of different materials has different load-bearing capacities and toughness. For example, the alloy steel lifting devices provided by HULK Metal have excellent strength and ductility and can withstand higher tensile force requirements.

Complexity of the construction environment

Environmental conditions at the construction site, such as wind, temperature, and humidity, will also have an impact on the tension calculation. Professional construction teams often adjust equipment selection and operation based on environmental factors to ensure the stability of the pension system.

The Importance of Tensile Testing

In order to ensure the performance of lifting equipment, strict tensile testing is an indispensable link. HULK Metal will undergo strict tensile testing before the products leave the factory, and issue relevant tensile reports to customers. The following are common tensile testing methods:

Static tension test

This test determines the ultimate load-bearing capacity of a lifting device by gradually increasing the load. It is mainly used to evaluate the equipment's ability to resist static damage.

Dynamic tensile test

This test simulates dynamic stress changes in actual lifting environments to ensure that the lifting device can maintain stable performance despite frequent load changes.

Fatigue test

Fatigue testing focuses on the performance changes of equipment after multiple uses, and evaluates its lifespan and reliability through repeated loading.

Breaking strength test

This test is mainly used to determine the breaking point of lifting devices under extreme conditions, providing a reference for hoisting design.

Engineering solutions for tension optimization

Reasonably plan the distribution of lifting points

The distribution of hanging points directly affects the uniformity of the pulling force. In the lifting of irregular components, the use of professional lifting devices and optimally designed lifting point locations can significantly reduce the risk of excessive stress on a single point.
