- Lifting precautions for double eyebolts
As a type of lifting sling, eye bolts are not unfamiliar to everyone and are often used in some lifting operations in life. In order to perform the lifting operation more stably, the use of eyebolts is often larger than one. The following Yunfan rigging will tell you about the precautions for lifting double eyebolts. 1. When lifting the double eyebolts, make sure that the two eyebolts are in the same plane. If necessary, adjust shims can be placed on the support surface. 2. The maximum lifting weight of the double eyebolts is only suitable for installing the eyebolts on steel In the case of gray or cast iron parts, overloading is strictly prohibited; 3. When the double eyebolts are lifted, the eyebolts should be of the same type and specification; 4. When the double eyebolts are lifted, the angle of the steel cable should not be greater than 90 degrees; Eyebolts must be screwed in until

- Dacromet for surface treatment of rigging products
Some customers have always asked before, what is Dacromet treatment? What is the difference between galvanized and plastic spray treatment? Next, Yunfan Rigging will introduce the Dacromet treatment in detail for everyone. 1. Super corrosion resistance: Dacromet film thickness is only 4-8μm, but its antirust effect is 7-10 times more than galvanized and spray-treated. The rigging products treated with Dacromet did not show red rust for more than 1200 hours after the salt spray test. 2. Hydrogen-free embrittlement: Dacromet's treatment process determines that Dacromet has no hydrogen embrittlement, so Dacromet is very suitable for coating of rigging products. 3. High heat resistance: Dacromet can withstand high-temperature corrosion, and the heat-resistant temperature can reach above 300 ℃. And traditional plating

- Heavy Shackle Introduction
Heavy-duty shackle is the most widely used connection tool in lifting operations, and is mainly used for connection parts that are often installed and removed in lifting operations. Heavy shackle material: Q235, 45 # steel, 40Cr, stainless steel, etc. Surface treatment: black (baked / painted), galvanized (white / basket / color) Heavy shackle production process: free forging. A simple mold is needed, and the blank is forged by a friction press to deform the blank to produce a heavy-duty shackle. Heavy-duty shackle product quality: The national standards of this product and international standards are strictly enforced in the production of heavy-duty shackles. The standard shall be spot-checked according to its requirements, and the test pieces shall fully comply with the regulations. The heavy shackles shipped from Yunfan Rigging will type "SR",

- How should the steel rope inspection system be set up?
According to the requirements of the Lifting Operation and Hoisting Equipment Management Regulations (LOLER), all steel wire rope equipment except for hoisting purposes must be thoroughly inspected every six months. The comprehensive inspection cycle stipulated by LOLER is a link in the entire equipment inspection work system, which is only a general requirement. Therefore, it is only applicable to general operating conditions. Regular comprehensive inspections in accordance with this rule often cannot guarantee 100% steel wire ropes Safe use in actual operations. So how to build a scientific and reasonable steel wire rope inspection system? A scientific and reasonable steel wire rope inspection system should be constructed under specific operating conditions. The more demanding the operating environment and the higher the frequency of use, the shorter the interval between two comprehensive inspections. This needs to be

- Use of tight rigging
The tight rigging is also called a tensioner. As the name suggests, it acts as a tensioner. This is different from other slings and cannot be used for lifting. Tight rigging is usually used with a chain. After locking with a tight rigging, the object will not fall off, which is safe and reliable and protects the object from damage. Tight rigging is used to tighten and strengthen the equipment, which plays a fixed role in the transportation, movement, shipment or storage of goods. The operation of the tight rigging is simple, and the efficiency is increased by more than ten times compared with other tightening methods. Tight rigging can be used for the fastening of goods on trucks, trailers, ships or rails, as well as the binding and fastening of steel, wood and various pipe articles. In addition, the anchor is also suitable for vehicle trailers and rescue applications. Qingdao Yunfan has provided various types of tight rigging for a long time, and we look forward to cooperating with you! (this

- Suggestions for handling of lifting chain rigging
The lifting chain rigging often breaks or welds during use. The reason may be that the quality of the chain rigging itself is defective or the chain is overloaded to lift and break the chain. In addition, some chain rigging that has no problem with its quality will also break after severe wear. After the lifting of the lifting chain rigging, some customers choose to weld the chain themselves in order to save money. Such errors are absolutely not allowed. The lifting chain rigging is processed through a series of complicated processes, and its rigidity, toughness and various properties meet the national lifting industry standards. And if welding by ourselves, not only the original load capacity of the chain rigging cannot be guaranteed, but also the chain rigging of the self-welded chain rigging changes a series of properties of the chain rigging at the factory, and it is easy to cause breakage again. So remind users, if you encounter lifting
