Introduction of Precast concrete accessories Lifting System
Precast concrete accessories play a key role in the construction and assembly of precast concrete components, providing an essential solution for the handling, lifting, and fixing of these components. One of the most important aspects of any precast concrete project is to ensure that the components can be safely lifted, transported, and installed. To achieve this, HULK Metal has developed specialized lifting systems that provide a safe and effective method for handling precast concrete. Here is a comprehensive introduction to three common lifting systems in precast concrete: Round head lifting nail system, Screw hanging system, and Plate lifting nail system.
Round head lifting nail system
The Round head lifting nail system is a rugged and versatile solution for handling precast concrete components. Due to its reliability and ease of use, it is widely used in various construction projects. The system consists of several key components, each of which is designed to ensure that heavy precast components can be safely lifted and manipulated.
Lifting Anchor
The Lifting anchor is also called the Lifting pin anchor, and in some areas it is also called the dog bone lifting anchor; it is the core of the Round head lifting nail system. These lifting anchors are embedded in precast concrete during the production process. They are usually forged from high-strength alloy steel with a safety factor of more than 3 times and are designed to withstand the tremendous forces encountered during lifting. The round head design ensures that the anchor can securely engage with the lifting clutch, providing a safe and reliable connection point for lifting equipment.
Lifting anchors are available in a variety of sizes and load capacities and can be used for a variety of precast components, from small panels to large structural components. The design of the anchor ensures that the load is evenly distributed, minimizes stress on the concrete, and reduces the risk of cracking or damage during lifting.
Lifting Clutch
The Lifting Clutch, also known as precast concrete lifting eyes, is a specialized lifting device that connects to the lifting anchor. It has a sturdy mechanism that locks securely onto the round head of the lifting anchor, ensuring a safe and stable connection during lifting operations. The lifting anchor is designed to be easy to use, allowing workers to quickly and efficiently connect and disconnect lifting equipment without complex tools or procedures.
The lifting clutch is carefully designed to handle a variety of load conditions and is tension tested to ensure that it meets strict safety standards. They are usually made of high-strength alloy steel to provide maximum durability and service life even in harsh construction environments.
Screw hanging system
The screw hanging system is another popular lifting solution used in precast concrete construction. The system is known for its versatility and ease of installation, making it an ideal choice for a variety of precast elements. The system includes two main components: lifting sockets and fixing sockets, both of which are designed to provide a secure connection point for lifting and fixing operations.
Precast Socket
The precast socket is a key component of the screw hanging system. It is divided into lifting sockets and fixing sockets, which are usually cast in precast concrete elements and provide a secure connection point for lifting equipment. The lifting socket is made of high-strength steel and is designed to withstand large loads without compromising the integrity of the concrete element.
There are several types of lifting sockets to choose from, each designed for specific load conditions and applications.
Lifting Socket
Lifting sockets demonstrate significant value in the field of reinforcement of precast concrete elements due to their excellent performance. Its flexibility makes it widely used in pipes, walls, panels, and other structures. Bypassing the steel bars through the transverse holes, the lifting socket can be firmly anchored within the concrete component, thereby ensuring the safety and stability of the lifting operation. This product is available in Metric and Rd thread sizes, and surface treatment options include zinc plating for increased corrosion resistance. In addition, hot-dip galvanized or stainless steel materials can also be provided according to customer needs to meet the use requirements in different environments.
Fixing Socket
Fixing sockets are designed with flat ends and cross-drilled holes, through which the reinforcement is inserted to ensure the effective transfer of static loads into the concrete structure. Generally, it is recommended to use fixing sockets only for fixing purposes and no additional technical approval is required. These fixing sockets are made of high-precision steel tubes and have excellent strength and durability. The surface treatment is available in galvanized versions and is also equipped with metric threads to meet different needs. In addition, hot-dip galvanized and stainless steel materials can also be customized according to customer requirements to cope with more stringent environmental conditions.
Lifting loop
HULK Metal Lifting Loop is the most economical solution for lifting applications, offering exceptional value without compromising on performance. Engineered with a 5:1 safety factor, it ensures high reliability and safety in lifting operations. The product has successfully passed CE certification and is manufactured in an ISO 9001-certified guaranteeing facility, with consistent quality standards. This Lifting Loop is compatible with nearly all lifting sockets featuring the same thread, providing versatile usage across different projects. However, it is not suitable for turning or pitching applications. Reuse is possible following a detailed inspection process, but it is not recommended for harsh or repeated use conditions. For safe application, the Lifting Loop should only be attached once the concrete has reached a minimum strength of 15 N/mm². In certain scenarios, it may be both economical and practical to leave the loop in place for specific project requirements.
Plate lifting nail system
The Plate lifting nail system is an efficient and versatile lifting solution that is particularly suitable for handling large and heavy precast concrete elements. The system is often used for the construction of structural components such as beams, walls, and slabs that require high load capacity. The Plate Lifting Nail System consists of several key components, including the spread anchor and the lifting ring clutch.
Spread Anchor
The Spread Anchor features an innovative spread-foot design, which significantly increases its pull-out capacity while enabling 360-degree load application, even with proper edge distances. This makes it particularly suitable for face or edge lifting of precast concrete panels during stripping, handling, or the horizontal-to-vertical rotation process. It is important to note, however, that when subjected to shear forces perpendicular to the void, the Spread Anchor may lead to concrete spalling, regardless of the edge distance.
Lifting Ring Clutch
The Lifting Ring Clutch is a specialized lifting device used in conjunction with the spread anchor. The lifting ring is made of high-quality alloy steel and is manufactured through a precision forging process, ensuring excellent durability and fatigue resistance. This design not only provides stable performance under harsh working conditions but also effectively improves the safety and reliability of lifting. Each locking ring undergoes 100% flux crack testing to ensure that the product is free of defects before leaving the factory and meets strict quality control standards. The product has a safety factor of 5:1, which means that it can be used safely within five times the normal working load, providing customers with great safety protection. It is suitable for lifting operations in many high-demand industries such as construction, bridges, and ships.
