In the field of modern industrial lifting, polyester webbing slings are widely used in machinery manufacturing, construction, port terminals, warehousing logistics, power engineering and other industries because of their lightness, softness, no damage to the surface of objects and strong load-bearing capacity. However, in actual applications, different working conditions, different material types, and different lifting equipment have different requirements for the length, width and even load-bearing capacity of the slings. So can polyester webbing slings be customized in different lengths and widths?
This article will focus on this topic and provide you with an in-depth analysis from multiple aspects such as the structural characteristics of polyester webbing slings, the importance of customization, the feasibility of customized content, influencing factors, and customization processes.
1. Basic composition and classification of polyester webbing slings
Polyester webbing slings are mainly made of high-strength polyester fiber (Polyester) material, and the surface is woven with industrial webbing technology. According to the usage and structural characteristics, common types include:
Flat Webbing Sling: double-layer or multi-layer flat belt structure;
Round Sling: made of jointless high-strength polyester filament core material wrapped in a ring, with outer webbing sleeve protection;
With Loop: loops are sewn on both ends for easy hook operation;
Endless Sling: no clear end, can be recycled 360 degrees;
Reinforced Sling: reinforced stitching or outer protective layer, used for lifting heavy objects.
Based on these types, users can customize the length, width, color, loop shape, surface reinforcement method and other parameters according to actual needs.
2. Why do you need to customize the length and width of polyester webbing slings?
2.1 Adapt to objects of different sizes
The hoisting object may be large equipment, small accessories or fragile glass. The size, weight and shape of each object are different. Using slings of uniform specifications is prone to problems such as incompatibility, uneven force and sliding danger. Therefore, the matching of length and width is the key to ensure the stability and safety of hoisting.
2.2 Meet different hoisting methods
Common hoisting methods include straight hoisting, double-limb hoisting, inverted U hoisting, winch hoisting, oblique hoisting, etc. Each method has different requirements for the length of the sling, especially when it is used in combination with a two-point hoisting or a crane arm or hook, the length of the sling must be precisely controlled to ensure the balance of the object.
2.3 Optimize the hoisting safety factor
The width of the sling directly affects the force area and unit tensile load during hoisting. The larger the width, the larger the contact surface, the more stable the hoisting, and the force per unit area will be reduced, thereby reducing the risk of wear and accidental breakage. Customizing the appropriate width will help improve overall safety.
2.4 Adapt to special working conditions
In high temperature, high humidity, corrosive environment or small space operation, standard size may not be applicable. By customizing slings of different lengths and widths, operational problems under special working conditions can be better solved.
3. Detailed explanation of polyester webbing sling customization parameters
When customizing polyester webbing slings, it is usually necessary to clarify the following key parameters:
Length: According to the actual lifting requirements, the sling length can be customized from 0.5 meters to 20 meters or even longer to meet the needs of different lifting heights and scenes.
Width: Common width specifications are 30 mm, 50 mm, 75 mm, 100 mm, 150 mm, 200 mm, etc. The width of the sling directly affects its load-bearing area and tension distribution, and is an important factor in determining the safety factor.
Number of layers: Conventional slings are mostly double-layer structures, but according to the load-bearing requirements, they can also be customized as three-layer, four-layer or with a thickened reinforcement layer to enhance the service life and load-bearing capacity.
Ring shape: Customers can choose different ring forms according to their needs, such as flat ring, flat ring with lining, hardened ring, etc., to adapt to different lifting methods and equipment interfaces.
Load tonnage: The rated load-bearing range that can be customized for polyester webbing slings is usually between 1 ton and 50 tons. When choosing, users should combine the actual weight of the object to be hoisted and consider a certain safety factor.
Color: The color of polyester webbing slings is usually used to quickly identify their rated load-bearing capacity. For example, purple represents 1 ton, green represents 2 tons, yellow represents 3 tons, and so on. This color coding helps on-site personnel quickly determine the specifications of the sling and improve operational efficiency and safety.
Identification labels can also be customized according to customer needs. The company logo, load parameters, safety tips, etc. can be printed on the label, which is convenient for enterprise management and improves product professionalism.
4. Factors affecting the price of customized polyester webbing slings
Although customized slings are highly flexible, the price will also be affected by the following aspects:
Raw material usage and specifications: The wider, thicker, and longer the sling is, the more consumables it will have, and the higher the price;
Process complexity: whether lining, double-layer sewing, protection reinforcement, or embedded core wire is required;
Order quantity: large-volume customization has a lower unit price, while small-volume customization is slightly higher;
Whether to customize labels and packaging: special printing, personalized logos, etc. will increase processing costs;
Delivery cycle requirements: urgent delivery may involve expedited fees.
Therefore, when choosing a supplier, it is recommended to clarify your own needs and compare the quotations and production qualifications of several manufacturers.
5. How does the customization process generally proceed?
The customization services provided by different companies may vary slightly, but the standard polyester webbing sling customization process generally includes the following steps:
Demand communication: The customer provides the parameters of the object to be hoisted (weight, size, hoisting method, etc.) and explains the usage scenario;
Technical confirmation: The manufacturer's technicians recommend suitable sling specifications, structures and materials based on the data;
Solution quotation: Specify the unit price, delivery date, packaging method, payment terms, etc.;
Sample proofing (if necessary): For large-volume orders or high-risk hoisting needs, it is recommended to test the sample first;
Mass production: After confirming the order, enter the production process;
Factory inspection: Each sling must undergo tensile testing and label review;
Logistics delivery: Pack and ship according to the customer's specified method;
After-sales service: Provide usage guidance, problem troubleshooting or secondary repurchase services.
6. How to choose a reliable sling customization manufacturer?
When choosing a customization manufacturer, it is recommended to evaluate its professionalism from the following aspects:
Does it have ISO9001 or EN1492 certification?
Does it have many years of experience in producing slings?
Can it provide product certificates and tensile test reports?
Does it have a complete customer service system and after-sales support?
Can customized samples and technical consultation be provided?
Choosing a company with qualification certification, production strength and engineering experience can ensure that the purchased slings are safe and reliable, accurate in size and stable in delivery.
As an important part of modern lifting operations, the standardized design of polyester webbing slings can meet some general scenarios, but in the face of diverse engineering needs, customized slings are particularly important. In particular, the difference in length and width is directly related to whether the lifting is stable, safe and efficient.
Whether it is large-tonnage equipment for port loading and unloading, precision machine tool lifting in machinery factories, or component lifting at construction sites, professional lifting solutions and customized lifting belts are required to ensure the success of the operation.
