Product Introduction

Polyester endless slings are made of high-strength polyester (polyester fiber) through a seamless circular weaving process to form a closed loop structure, with no joints or breakpoints, and the overall force is evenly distributed. The product covers the load-bearing requirements from 1 ton to 200 tons, and supports customization of loop length, bandwidth and functional coating. It is suitable for vertical hoisting, binding and fixing, and multi-leg combined hoisting scenarios, and is an efficient and safe flexible solution in industrial hoisting.

Product Advantages and Features

Seamless loop, balanced force bearing

The circular weaving process eliminates the weak points of joints in traditional slings, and the load-bearing capacity around the loop is consistent.

Lightweight and high-strength, easy to operate

The density of polyester is only 1/4 of that of steel, with excellent flexibility. It can be quickly sleeved and hung on the hoisted object, improving manual operation efficiency by 60%, especially suitable for high-altitude or narrow space operations.

Abrasion and cut resistant, long service life

The surface is treated, and the friction coefficient is increased by 40%, extending the service life by 2-3 times in rough surfaces or frequent friction scenarios.

Strong resistance to environmental corrosion

It can withstand low temperatures of -40℃ to high temperatures of 120℃. The outer layer can be added with silicone and PU coatings to resist erosion by weak acids, weak alkalis and salt spray, and has stable performance in chemical, marine or desert environments.

Adaptable to multiple scenarios, flexible and efficient

It can be used alone as a vertical hoisting sling, or can realize balanced hoisting through multi-leg combinations (such as 2-leg, 4-leg), adapting to objects of different shapes and weights, reducing the frequency of tool replacement and improving the continuity of operations.

Industry Applications

Widely used in wind power equipment installation (blade loop binding and lifting), petrochemical pipeline maintenance (valve/flange vertical lifting), logistics and warehousing (heavy cargo container binding and fixing), construction sites (reinforcement/steel beam combined hoisting), aerospace manufacturing (flexible flipping of engine components) and emergency rescue (quick cleaning of heavy objects in earthquake ruins) and other fields. With the characteristics of "seamless, wear-resistant, lightweight and multi-purpose", it has become the core hoisting tool for more than 800 leading enterprises in the industry worldwide.
