US Type Eye Grab Hook 323C/323A is an American eye grab hook. It is usually made of 45# carbon steel or 40Cr alloy steel, forged and quenched and tempered. The surface can be electro-galvanized, hot-dip galvanized or powder coated. It uses a special shallow throat to grab the chain to prevent the chain from slipping. It is often used for cargo tying, traction, etc. It has a wide working load range and a safety factor of 4:1 or 6:1.

Sturdy and durable material: usually made of high-strength steel such as 45 carbon steel or 40Cr alloy steel, after forging and quenching and tempering, it has high strength and good toughness, can withstand large tensile force, strong impact resistance, and can adapt to a variety of harsh working environments.
Excellent surface treatment: the surface can be electroplated galvanized, hot-dip galvanized or powder coated, which effectively prevents rust and corrosion, prolongs service life, and improves the appearance texture. Hot-dip galvanizing and other treatment methods can provide better protection in outdoor environments.
Firm and reliable grasping: the special shallow throat design grasps the chain, which can accurately engage with the chain links to prevent the chain from slipping, and can ensure the stability of the connection in operations such as cargo bundling and traction, ensuring the safety of the operation.
Various specifications and sizes: the size ranges from 1/4" to 3/4", corresponding to different working loads, from 2600 pounds to about 24700 pounds, which can meet the bundling and traction needs of various cargoes of different weights, and is applicable to a wide range of scenarios.
High safety factor: The safety factor is generally 4:1 or 6:1, that is, the breaking load is usually 4 or 6 times the working load. After rigorous load testing, it meets the performance requirements of US federal specifications and is safe to use.
Clear and unambiguous markings: Usually "G70" or "G43" is marked on the hook to facilitate users to quickly identify the applicable chain grade, facilitate correct selection and use, especially for 70-grade transport chains and 43-grade high-strength test chains.
Construction: On construction sites, it can be used to hoist and fix building materials. For example, when lifting steel and wood from the stacking place to the construction site, or when building scaffolding, it helps to fix and connect related parts to ensure construction safety and efficiency. It can also be used with equipment such as cranes and winches to accurately position and install prefabricated components.
Cargo transportation: It is widely used in trucks, trailers and other transportation tools for bundling and fixing goods. The chain can be passed through the eye, and the specific chain link of the chain can be grabbed with a grab hook to firmly bind the goods to the transportation tool to prevent the goods from moving and falling during transportation and ensure transportation safety. In container transportation, it can also be used to assist in fixing the goods in the container.
Ship operations: During the loading and unloading process of the ship, it can be used to connect the sling and the cargo to facilitate lifting and handling of the cargo. It can also be used in the ship rigging system to adjust the length and position of the rope and chain to ensure the stability of the ship's rigging during navigation. It can also assist in lifting maintenance tools and parts during ship maintenance.
Agricultural field: In agricultural production, it can be used to tow and fix agricultural machinery and equipment. For example, when a tractor tows farm implements, the chain can be connected through the grab hook to achieve reliable towing of the farm implements. It can also be used to bundle and fix agricultural products and related packaging materials during the storage and transportation of agricultural products.
Industrial manufacturing: When moving heavy equipment or parts within the factory, the grab hook can be used in conjunction with the chain and lifting equipment to move large machine tool parts, molds, etc. from one station to another. In the assembly link of the production line, it can help accurately locate and fix parts, improving assembly accuracy and efficiency.
Q1: What are the load capacities of the 323C and 323A models?
The load capacity varies depending on the specific specifications. The general working load range is from 2,600 pounds to about 24,700 pounds. 323C is usually suitable for smaller chains and corresponding loads, and 323A can be adapted to larger chains and higher loads. Please check the product logo or instructions for details.
Q3: What is the safety factor of this grab hook?
The safety factor is usually 4:1 or 6:1, that is, the breaking load is 4 times or 6 times the working load, which can ensure safety during use.
Q3: What material is the grab hook made of?
It is generally made of 45 carbon steel or 40Cr alloy steel, which is forged and quenched and tempered, and has high strength and toughness.
Q3: What are the surface treatment methods?
Common surface treatment methods include electrogalvanizing, hot-dip galvanizing and powder coating, which can effectively prevent the grab hook from rusting and corrosion. Users can choose according to the use environment.
Q3: What chains can be used with it?
Usually suitable for grade 70 transport chain and grade 43 high-strength test chain, the hook is usually marked with "G70" or "G43" for easy identification.
Q3: What is the maximum diameter of the chain that can be grabbed?
The size range is from 1/4" to 3/4", and different sizes correspond to different chain diameters. For example, a 1/4" grab hook is suitable for chains of corresponding diameters. For details, please refer to the product specification table.
Q3: How to grab the chain correctly?
Use the special shallow throat of the grab hook to align it with the chain link so that the chain is embedded in the throat to ensure that the chain and the grab hook fit tightly to prevent slipping.
Q3: Can it be used for vertical lifting?
This grab hook is mainly used for cargo bundling, traction, etc. It is generally not recommended for vertical lifting operations. If it is needed for similar scenarios, it should be used with caution according to its rated load and relevant safety regulations.
Q3: How to perform daily maintenance?
Regularly check the surface of the grab hook for cracks, wear or corrosion, and clean the surface debris. Check whether the shallow throat is deformed to ensure that the chain can be grabbed normally. If there is any abnormality, it should be replaced or repaired in time.
Q3: At what extent does the grab hook need to be scrapped?
When the wear of the dangerous section exceeds 10% of the original size, or the opening increases by 15% compared with the original, or cracks or torsional deformation exceeds 10°, it should be scrapped.
