How can I use the sling correctly?

The surface damage of the sling is an important factor in the reduction of the strength of the sling, so when the surface is worn, the sling will be damaged sharply. Some fracture (not fault) of the fibers on the surface of the sling is inevitable, as long as it is not too large, it will not affect the use.

1. When using, the hoisting belt is directly hung into the center of the hook and directly hung at the hook tip position, 2. The hoisting belt is not allowed to cross and twist, knotted and twisted in use, and the correct hoisting special link should be used to link.

3. The use process must be commanded by personnel with relevant qualifications, and it is strictly forbidden to overload it.

4. When the two slings are operating, the two slings are directly hung into the double groove, and each is hung in the symmetrical stress center of the double hook; When the four slings are used, every two slings are directly hung into the double hook, pay attention to the inner sling can not overlap and squeeze each other, and the sling should be symmetrical to the hook force center.

5. When encountering goods with sharp corners and edges, sheaths, corners and other methods must be used to protect the sling belt to prolong the service life of the sling and eliminate potential safety hazards.

6. When a single hoisting belt is needed to lift the cylinder, a double-turn choke ring should be used for bundling.

It should be noted that when using the sling belt, be sure to fasten the belt faucet tightly and check it many times before use, and stop using it immediately if you find any problems. It should be noted that the various parts on the lifting belt shall not be disassembled without permission, and each small part on the lifting belt is related, if accidentally removed, the small parts are easy to lose or cannot be restored to install back. Although there are many types of slings, all slings have a principle when they are used, and the users must be trained or have professional people around them to guide them to wear them.

Because the sling is different due to the different types, the way to wear is not the same, if there is no professional learning, it is easy to lead to the wrong wearing, and the consequences caused by the use of the wrong situation should not be underestimated.

The lifting of the steel belt stove is generally divided into two types of hoisting: horizontal and vertical.

The general hoisting of steel strip coils has a C-type spreader and an electric permanent magnet spreader. You can use it according to your actual situation.

Summary. Hello, steel structure hoisting can be used with slings.

Hello, steel structure hoisting can be used with slings.

Before hoisting, the construction site must be surveyed, and the travel route of the crane must be determined according to the actual situation of the construction site. Clear the site of obstacles to ensure that the road is clear. The on-site component stacking site and hoisting area site have been processed, which is solid and flat to meet the hoisting requirements.

Determine the parking position of the crane, as well as the stacking position of the components, and configure the skids. Temporary electricity, machinery, supports, safety facilities, etc. are ready. The construction personnel have made technical and safety disclosures.

The components are classified into the site according to the hoisting order, and proofread to remove the defective components.

Summary. Dear, I'll answer this question for you. 1. Lifting and unloading lifting objects with a length of more than 9 meters must use a traction rope.

2. The tow rope is made of hemp rope or plastic rope, the rope diameter is 8-12mm, the length is 5-8 meters, the tow rope should be kept by a special person, checked frequently to ensure safety and effectiveness, such as wear and tear beyond the safety range to be replaced in time. 3. Before the lifting of the lifting object, hang the tow rope at one end of the hanging object, and after the lifting object is lifted, the rope of the designated rope operator will grasp the direction of the lifting object to adapt to the loading and unloading target, and the traction rope should be kept tight to ensure that the direction of the lifting object can be manipulated, and the operator of the operation should keep a safe distance from the lifting object. Adjust the direction of the hanging object according to the needs of safe operation.

4. When the lifting rope reaches the target and descends to a certain height and the traction rope cannot be operated safely, the traction rope should be released and the hook should be operated instead. 5. After the hanging object is put down, untie the traction rope first, and then pull out the sling by the crane. During the epidemic period, remember to make an address for good precautions, wear a mask, and try not to go to a large number of places, if you are satisfied with this time, please like it, thank you very much.

We use a lot of materials in the decoration, such as the sling is also one of the common materials, of course, for the decoration of the white may not understand the sling, so we naturally do not know how to choose, so we need to understand the sling specifications and model list. I shoot a lot of materials to be used in the decoration, such as the sling is also one of the common materials, of course, for the decoration of the white may not understand the sling, so we naturally do not know how to choose, so we need to understand the sling specifications and models, in addition to the use of the sling precautions we also have to figure out, after all, no matter how good the material, no matter how good the thing, we must understand the use.

Sling specifications and model list

At present, there are many manufacturers of domestic lifting belts, and their technical performance and specifications are roughly as follows: technical characteristics and technical standards: JB T8521 - 1997;Material:

polyester, polypropylene, nylon; Safety factor: 6 8;Elongation: 2 5 under the ultimate working force; Length :

According to customer requirements; Type: Single-layer, double-layer, four-layer.

The flat sling is made of PES by braiding and stitching. And the two ends of the hoisting can use reinforced ring eyes or metal fittings to improve the strength. The flat belt is woven by the loom at one time, and processed by different stitching methods into old rotten, divided into single layer and double layer, the standard tonnage of the flat belt can be distinguished by color, but also according to the different width, to distinguish different bearing tonnage.

In the hoisting operation, it can provide a wide and smooth bearing surface, which is particularly suitable when hoisting objects with soft surfaces, because there is no contact with metal parts, the damage caused to the surface of the hoisted object is extremely slight.

Attention should be paid to the use of lifting straps

1. Do not use damaged slings;

2. When hoisting, do not twist or twist the sling;

3. Don't let the sling tie the knot when using;

4. Avoid tearing the sewing joint part or overloading;

5. When moving the sling, do not drag the sling;

6. Avoid forcibly grabbing or causing the load of the sling;

7. Each sling must be carefully checked before use;

8. Taperene has the function of resistance to inorganic acids, but it is susceptible to damage from organic acids;

9. Fiber fiber is suitable for use in places that are most resistant to chemicals;

10. Nylon has the ability to resist strong organic acid, and is susceptible to the damage of facial acid, and the loss of strength can reach 15 when it is damp;

11. If the sling is contaminated by chemicals or used at high temperatures, you should seek reference from the first supplier.

In fact, for the selection of hoisting, we must understand the use of attention, after all, when we choose, we must not be careless, we must understand the use of attention, and at the same time do not buy models when choosing, we must choose according to the actual requirements, so as to avoid damaging the function.

This practice is not allowed for the following reasons:1. Overlapping will lead to increased friction, which will cause the lifting belt to bear overload and be easily damaged or broken.

2. The hoisting belt is easy to deform after overlapping, which affects the hoisting effect and safety.

3. If there are defects, abrasive damage, tears or other damage on the hoisting car belt, the problem will be magnified when overlapping, making it more prone to failure, which poses a threat to the safety of lifting items and even personnel.

4. The overlapping use of the lifting belt does not meet the design and use specifications of the lifting belt, which is easy to cause accidents and bring potential safety hazards to personnel and items.

1. It is strictly forbidden to use it with overload.

2. When the two hoisting belts are operating, the two hoisting belts are directly hung into the double hooks, and the hoisting belts are hung in the symmetrical stress center position of the double hooks; When the four slings are used, every two slings are directly hung into the double hook, pay attention to the slings in the hook can not overlap and squeeze each other, and the slings should be symmetrical to the center of the hook.

3. When the hoisting belt is used, it is not allowed to use the bolting method for surrounding.

4. When the lifting belt is used, the lifting belt should be hung directly into the center of the hook and cannot be hung at the tip of the hook.

5. In the hoisting effect, the hoisting belt is not allowed to cross, twist, knotted and twisted, and the correct hoisting belt special link should be used to link.

6. When encountering goods with sharp corners and edges, sheaths, corners and other ways must be adopted to protect the sling to prolong the service life of the sling. It is strictly forbidden to use slings on rough surfaces. So that the sling is not scratched by the edges and corners and the rough surface.

7. When hoisting pipe objects, the correct hoisting method should be adopted, and the hoisting angle is too large and will cause potential safety hazards.

8. The items should not be pressed on the lifting belt, which will cause damage to the lifting belt, and the lifting belt should not be tried to be pulled out from below, causing danger. The object should be padded to allow enough space for the sling to be taken out smoothly.

9. The hoisting belt should not be dragged on the ground or rough surface.

10. After use, the hanging strap should be hung and stored.

When hoisting, do not twist or twist the sling; Do not let the sling get knotted when using; Avoid tearing the sewing joint or overloading it; When moving the sling, do not drag the sling; Avoid forcibly grabbing or causing the load of the sling; Each strap must be carefully inspected before use; Taperex has the function of resistance to inorganic acids, but is susceptible to damage from organic acids; Fibre is suitable for places that are most resistant to chemicals; Nylon has the ability to resist strong organic acid, and is susceptible to the damage of facial acid, and the loss of strength can reach 15% when wet;

There are many types of slings, and the kind of slings that we commonly see are generally used to lift objects, and the shape is mainly flat. Compared with the traditional small cylindrical lifting belt, the force range of this flat lifting belt will be much larger, and it will be more stable and safe to fix large heavy objects.

The sling is also available in a variety of different materials, and different materials are suitable for different types of objects to be lifted. For example, the transportation of some chemicals should use specially made and special materials to avoid the corrosive effect of chemicals on the sling and reduce the service life of the sling. Therefore, choosing the right sling is very critical for production enterprises, and different enterprises should choose slings according to their own production needs to ensure the safety and efficiency of the production process.
