Product Overview

The High Quality OEM Length Round Sling 1–150 Ton Heavy Duty Endless Polyester Lifting Webbing Sling is a flexible textile lifting solution designed for industrial cargo handling, crane lifting, machinery installation, construction, and heavy-duty rigging applications.

The sling uses a continuous polyester load-bearing structure with a protective outer cover, creating a soft and flexible round profile that can conform around different load shapes. The endless design allows the sling to be configured in vertical, basket, or choker lifting arrangements according to the applicable Working Load Limit (WLL) and manufacturer's instructions.

With capacity options from 1 ton to 150 tons, the product range can cover applications from general warehouse handling to engineered heavy lifting. OEM manufacturing allows buyers to specify sling length, WLL, cover color, label information, safety factor, packaging, and other project requirements.

Product Features

1. 1–150 Ton Capacity Range

The round sling product range supports different lifting requirements from 1 ton up to 150 tons.

Typical applications include:

1.General cargo lifting

2.Machinery handling

3.Construction projects

4.Steel structure lifting

5.Heavy equipment installation

6.Industrial engineering projects

The actual WLL depends on the sling construction, lifting configuration, sling angle, and applicable standard.

2. Endless Round Sling Design

The continuous endless construction allows the sling to be positioned around different loads without fixed end fittings.

It can be used in:

1.Vertical hitch

2.Choker hitch

3.Basket hitch

The WLL must be confirmed for the specific hitch configuration before lifting.

3. High-Tenacity Polyester Construction

The load-bearing core is manufactured from high-tenacity polyester fiber.

Key characteristics include:

1.High strength-to-weight ratio

2.Flexible structure

3.Lightweight handling

4.Good abrasion resistance

5.Easy storage

6.Suitable for repeated lifting operations

4. Soft Round Profile

The round profile allows the sling to conform around the surface of a load.

Compared with rigid metal lifting components, the textile contact surface can help reduce the possibility of scratches or surface damage on painted, coated, polished, and finished cargo.

For loads with sharp edges, suitable protective sleeves or edge protection should be used.

5. OEM Length & Specification

Factory-direct OEM production allows customization based on project requirements.

Available options include:

1.WLL

2.Sling length

3.Sling diameter

4.Cover color

5.Safety factor

6.Identification label

7.Customer logo

8.Packaging

9.Special construction

Technical Specifications

WLL & Color Identification

For round slings manufactured according to commonly used European capacity color identification conventions, the cover color can help identify the nominal WLL.

For capacities above 10 tons, manufacturers may use additional color or labeling systems. The actual WLL must always be confirmed from the identification label and manufacturer's documentation.

Product Advantages

Applications

Heavy Machinery Lifting

Suitable for lifting and positioning excavators, generators, motors, industrial machinery, and large equipment.

Steel Structure Handling

Used for lifting fabricated steel structures, beams, frames, pipes, and metal components.

Construction Projects

Applied for lifting precast components, construction machinery, building materials, and structural assemblies.

Factory & Warehouse Operations

Suitable for material handling, equipment relocation, loading, and unloading operations.

Heavy Industrial Engineering

High-capacity configurations can be used in engineered lifting applications where the required WLL and sling configuration are properly specified.

How to Select a 1–150 Ton Round Sling

For professional lifting applications, buyers should provide the following information when requesting a quotation:

1. Load Weight

Confirm the maximum cargo weight to determine the required WLL.

2. Lifting Configuration

Specify whether the sling will be used in:

1.Vertical hitch

2.Basket hitch

3.Choker hitch

3. Sling Length

Provide the required effective length or circumference according to the sling design.

4. Load Shape

The load shape and contact points affect sling positioning and whether additional protection is required.

5. Edge Conditions

Sharp edges can damage textile slings. Edge protectors should be used where necessary.

6. Working Environment

Confirm whether the sling will be exposed to heat, chemicals, moisture, abrasion, or outdoor conditions.

Manufacturing & Quality Control

Production of the endless polyester round sling includes controlled manufacturing and inspection procedures.

Polyester Fiber Inspection

Raw polyester materials are inspected before production.

Load-Bearing Core Production

The continuous polyester core is manufactured according to the required capacity and construction.

Protective Cover Production

The outer sleeve is produced to provide protection against normal abrasion and handling conditions.

Length & Dimension Inspection

Finished sling length, cover dimensions, and identification information are checked.

Stitching & Cover Inspection

The protective cover and seams are inspected for defects and proper assembly.

Load Testing

Proof/load testing can be arranged according to the applicable standard and customer project requirements.

Final Inspection

Finished products are inspected and labeled before packaging and shipment.

Safety Considerations

Before using an endless polyester lifting sling, operators should:

1.Check the WLL identification label

2.Select the correct hitch configuration

3.Inspect the sling before use

4.Avoid exceeding the rated capacity

5.Protect the sling from sharp edges

6.Keep the sling away from excessive heat

7.Avoid chemical exposure that is incompatible with polyester

8.Never use a damaged sling

9.Follow the manufacturer's lifting instructions

The sling capacity is configuration-dependent. A 10 ton sling, for example, does not automatically provide 10 tons WLL in every lifting arrangement.

FAQ

Q1: What is an endless round sling?

An endless round sling is a continuous textile lifting sling without fixed end fittings. Its continuous loop allows it to be used in vertical, basket, and choker configurations according to the rated capacity.

Q2: What capacity range is available?

The product range can be manufactured from 1 ton to 150 tons, with the exact construction depending on the required WLL and application.

Q3: What material is used for the round sling?

The load-bearing core is manufactured from high-tenacity polyester fiber with a protective textile cover.

Q4: Can the sling length be customized?

Yes. OEM length, WLL, cover color, label, logo, packaging, and other specifications can be customized for bulk orders.

Q5: What standard applies to endless round slings?

Polyester round slings can be manufactured according to EN 1492-2, subject to the specific product configuration and applicable certification requirements.

Q6: Can high-capacity 50–150 ton round slings be manufactured?

Yes. High-capacity configurations can be produced for engineered lifting applications. For 50–150 ton orders, buyers should provide the required WLL, sling length, lifting configuration, load dimensions, and project requirements so the sling construction can be properly specified.
