Eye Grab Hooks Details
If you want to buy the right product, you need to fully understand it. Know its material, production process, specifications, etc. In this way, you can better calculate the price of the entire order and know whether the merchant really wants to do business with you.
What is Eye Grab Hooks
Eye grab hooks are forged from a single piece of high performance alloy steel bar. It is designed to use grab to grab the chain link to shorten the chain length in the lifting (tensioning) system or to form a closed loop to bundle objects. The eye is used to link one end of a closed loop chain, or to link a lifting equipment chain, wire rope or cable.
Its Structure
It is a whole and can be divided into two parts according to its function.
Hooks Eye:
Used to link one end of a chain, or to link the chain, wire rope and cable of equipment. It cannot be directly buckled into the ring of the chain, so it often needs to be used with Connecting Links or other link accessories.
Hooks Body:
Its middle cavity extends straight from the opening to the inside, and only allows chains below this width to be put in. For wider links, we can just hook one side of the link, and if the link is smaller, both sides need to be put into the inner cavity.
The Types of Eye Grab Hooks
We can classify hooks according to their opening size, surface treatment and material.
The common opening sizes of Eye Grab Hooks can be found in the "Size" column in the table above. Common surfaces include electro-galvanized, hot-dip galvanized and powder sprayed. The materials include high-performance carbon steel and high-performance alloy steel.
Note:
The performance of the material determines the performance of the Eye Grab Hooks. Please carefully compare the table and select the most suitable one according to the load used.
How it work:
Step 1:
Before using, you need to consider whether the load capacity of Eye Grab Hooks can meet the requirements. Its opening size needs to be slightly larger than the thickness of the steel bar of the chain.
Step 2:
Depending on the material of the link, there are two situations.
Linking closed ends:
Use connecting links to connect the eyes of hooks, the closed loops at the end of a chain, or the closed loops at the end of a wire rope.
Linking openable ends:
Directly link the ends to the eyes of hooks.
Step 3:
When using, you need to consider that there are two situations based on the width of the loop:
When the width of the chain link exceeds the curvature of the hook:
You can only hook the hook on one side of the chain link.
When the width of the chain link is less than the depth of the hook:
You need to hook both sides of the chain link.
Eye Grab Hooks Production:
It is produced from a steel bar through a hot die forging process.
Its process is:
1. Determine the production plan according to your needs;
2. Purchase raw materials and conduct random inspections. Only qualified raw materials can be used for production;
3. Arrange production lines according to order size, and reasonably dispatch equipment and employees to start order production;
4. Cut steel rods into specified sizes;
5. The electromagnetic induction tube heats the steel rod to a specified temperature;
6. The steel bars are pre-treated using a hot bending die;
7. Put the semi-finished product into the mold;
8. Eye Grab Hooks with flash are produced using a forging machine and open grinder;
9. Deburring, grinding, shot blasting, (heat treatment is only done upon customer’s request) to complete the finishing process;
10. Surface treatment;
11. Packing and shipping;
12. QA service starts after delivery
Eye Grab Hooks Quality Inspection:
Eye Grab Hooks are strictly tested, especially the load performance test. We have a complete and advanced testing equipment to complete more tests to ensure that it meets your requirements. You can click Learn More to view the details, or contact us to learn more.
Raw Material Test:
We can use a photometer to test the composition of raw materials, and only qualified raw materials will be used for order production.
Tensile test:
We will use a tensile force of 4 times the safety factor for destructive testing, and the entire order will be strictly inspected to ensure that the goods are almost 100% qualified.
Salt spray test:
Upon request from the customer, we can strictly test the rust and corrosion resistance of the eye grab hooks.
