In various industrial and engineering fields, flat slings are known for their The unique advantages make it an indispensable lifting tool.
1. Characteristics of flat lifting straps
Flat slings are made of high-quality synthetic fibers and advanced weaving Made with technology and equipment. It has the following salient features:
- High safety factor: slings with 4, 5, 6, 7, and 8 times safety factors can be produced according to customer needs. The production range covers 0.5t - 100t for loads of different weights. Provide reliable protection.
- Easy to identify: International standard colors are used to distinguish different carrying capacities, and they can also be distinguished based on bandwidth, making it easier for users to quickly select the appropriate lifting belt.
- Protect the hoisted objects: During hoisting operations, it will not cause damage to the surface of the hoisted objects. It is suitable for hoisting various items with high surface requirements.
- Rich product series: According to different lifting environment requirements, it can be divided into ordinary type, fire-proof type, fluorescent type, high-strength type, acid-resistant type, wear-resistant type, oil-repellent and waterproof type, etc. series to meet the needs of various complex working conditions.
2. Usage steps and methods
-
Reasonably choose specifications
When selecting the specifications of the lifting strap, factors such as the size, weight, shape, and lifting method of the load to be lifted need to be comprehensively considered, as well as the working environment and load type. It is necessary to select a sling with sufficient capacity and the appropriate length to meet the usage method. If multiple slings are used to lift loads at the same time, the same type of slings should be selected, and the raw materials of the flat slings cannot be affected by the environment or load. -
Note that the sling limits the angle of use
When using flat slings with soft lifting lugs, the minimum length of the lifting lugs used must not be less than 3.5 times the maximum thickness of the hook in contact with the lifting lugs, and the movable lifting lug clip The angle cannot exceed 20°. When connecting a sling with a soft lifting eye to a lifting appliance, the contact parts of the sling and the lifting appliance must be consistent, unless the axial width of the sling does not exceed 75mm, and the bending radius of the lifting accessory must be at least the axial width of the sling. 0.75 times. -
Follow lifting experience
Before starting hoisting, a lifting and light operation plan should be planned. Carefully consider the matching of the end section of the sling, auxiliary accessories and lifting equipment. -
Correct connection method
The sling is correctly positioned and connected to the load in a safe manner. The sling must be placed on the load so that the load can evenly affect the width of the sling. Slings should never be knotted or twisted, and the seam should not be placed on hooks or lifting equipment. It should be placed on the upright part of the sling to prevent damage to the tag by keeping it away from the load, hooks and locking angles.
3. Precautions for use
- Avoid overload: It is not allowed to use slings with overload. If several slings are used at the same time, the load should be distributed as evenly as possible on several slings.
- Protect the soft ring: The soft ring is not allowed to be connected to any device that may cause damage to it. The hanging device connected to the soft ring should be smooth, without sharp edges, and its size and The shape should not tear the sling seams.
- Move correctly: When moving slings and cargo, do not drag.
- Prevent knotting and long-term hanging: It is not allowed to knot or twist the lifting belt, and the lifting belt is not allowed to hang goods for too long.
- Avoid usage scenarios of unsheathed slings: It is not allowed to use unsheathed slings to carry goods with sharp corners and edges.
- Illegal operations are prohibited: when the goods stay on the lifting belt, the lifting belt must not be pulled out from the load-bearing state.
- Guidelines for use in special environments: If the sling is used in abnormal environments such as high temperature situations or lifting chemical substances, the manufacturer's guidance and recommendations should be followed.
- Clean promptly and store correctly: After the sling is dirty or used in an environment prone to acid or alkali, it should be rinsed with cold water immediately. Lifting straps should be stored away from light and without ultraviolet radiation. Lifting straps should not be stored near open flames or other heat sources.
Flat lifting straps are an important lifting tool and should be used correctly and maintenance can ensure the safe and efficient performance of hoisting operations. In practical applications, it is necessary to strictly abide by the usage steps and precautions so that the flat lifting belt can better serve various engineering and industrial activities.
