If you want to buy a more suitable Clevis Grab Hooks, you must first have a better understanding of it. We are here to introduce in detail everything about it, what it is, its structure, its strength level, its usage, its production process, etc. If these are not comprehensive enough, you can also contact us to learn more.
It is designed based on the chain structure, its inner cavity is parallel and narrow, and can only allow the chain ring to pass horizontally. When it is stuck on the chain, the chain length cannot be adjusted anymore. This does not work if it is used to connect the wire rope. When we choose it to connect the chain, be sure to consider the thickness of the link and the width of the cavity. Its material is made of carbon steel and alloy steel. Our parameter table lists the performance of these two materials. Please choose the more appropriate one based on actual use.
Its structure includes clevis ear, hook body, clevis pin, safety pins. Because the structural characteristics of Grab Hooks make it difficult to decouple after connecting the chain, there is no latch structure.
Note: Clevis Ear and Hook Body are forged in one piece.
It is a structure with a certain width. Its function is to be stuck in a chain or wire rope with two holes on it, which facilitates the Clevis Pin to pass through and complete the link to the lifting end.
It is a thicker pin inserted into the hole of the Clevis Ear to link the lifting end and the Clevis Grab Hooks, which carry axial shear force during lifting.
Used to insert a hole at one end of the Clevis Pin to prevent it from being released from the Clevis Ear.
It is a hook-shaped structure, the inner wall is linear in shape and the end is semi-circular in shape, and the inner cavity only allows a series of specific thicknesses to enter. Because of this, once Clevis Grab Hooks hooks a certain chain link, it is impossible to adjust the chain length.Of course it can also be used to connect wire ropes of certain thickness.When choosing, be sure to consider the thickness of the chain ring and wire rope to avoid being unusable.
It can be classified according to strength, material, surface treatment, etc. Their functions are consistent, the difference is in WLL, appearance, and corrosion resistance. If you want to know more, you can contact us to get it.
We need to take out the Safety Pins and Clevis Pins (if they are separate from the Clevis Grab Hooks, this step is not needed).
We need to snap the Clevis Ear into the end of the chain or wire rope.
We need to insert the Clevis Pin into the hole of Clevis Ear and the Safety Pin into the hole of Clevis Pin, and then the Clevis Grab Hooks and the chain or wire rope is locked.
Hooks into the link specified by the load chain (the length of the chain needs to be calculated in advance) or wire rope and other objects, the tensioning machine slowly applies tension to keep the entire structure in a load balanced state to prevent decoupling.
After you inquire, we will arrange samples, confirm that the samples have passed your inspection and start mass production, raw material procurement, cutting, heating, forging, finishing, surface treatment, quality inspection, packaging and shipment, and after-sales service. We strictly implement ISO 9001 standard management, so you can purchase with confidence.
We directly purchase high-strength carbon steel or alloy steel rods from globally certified steel mills. Before the raw materials are put into use, they need to conduct chemical composition and mechanical properties sampling to ensure that the material meets the requirements of Clevis Grab Hooks.
We have CNC cutting equipment that can accurately divide the material according to the size of hook and ear pieces. The blank length is more consistent than the traditional method, providing the best blank for subsequent heat treatment and forging.
We use electromagnetic induction heating technology to make the blank reach the required temperature faster and the temperature uniformity reaches within ±5℃. It heats faster and more energy-efficient than old electric furnaces, while minimizing the growth of grains.
We use open die forging to complete the integrated forging and Clevis Grab Hooks are formed at one time.
We will conduct initial inspections of appearance and dimensions immediately after forging, and error control is stricter than the industry's general standards.
We will finely process Clevis pin holes, chamfers and flashes through the machining center to ensure that each hole is smoother and smoother, and prevent the concentration of obtuse stress.
We will spray hot-dip galvanized, electro-galvanized or high-temperature cured powder according to your needs, with higher corrosion protection than ordinary coatings.
We will use a tensile testing machine to conduct 2 times working load detection and 4 times extreme load break test, and sample to perform hardness and impact tests. After passing, we use anti-rust paper and customized cartons to package them in batches to improve the transportation protection effect.
We will arrange wooden boxes in advance and arrange container trailers. We have a freight consulting center to help you find a more suitable international freight company.
We provide a full range of after-sales service to provide returns, exchanges and replenishment services for products with any quality problems.
Our quality control center can complete the inspection of Clevis Grab Hooks in terms of tolerances, shapes, surface treatment quality and more. In terms of tension detection, we will use 2 times the tension of safety factor to detect tension, and use 4 times the limit test. You can contact us at any time to visit the Quality Control Center.
We used electron microscope to detect the internal structure of Clevis Grab Hooks.
Hardness meter tests the hardness of Clevis Grab Hooks.
We will use a 2-fold safety factor tension to detect the load of Clevis Grab Hooks, and use a 4-fold safety factor tension to perform damage detection.
Ensure that Clevis Grab Hooks meet impact performance requirements.
