Tension Links 101

A tension link load cell is commonly used in lifting, both for short and long distances and weighing applications. This type of load cell sensor generally has capacities ranging from 2.2K lbf to 1.1M lbf (5 to 500 metric tons). All tension links are available in custom versions and large capacities based on the customer’s project requirements.

Interface’s Tension Load Link series is manufactured from high-tensile aluminum and stainless steel. Matched to shackle sizes, the load links have a rugged design for use in harsh environments on the surface and in water. The tension links are environmentally sealed to IP65, IP66, or IP67. There are higher ratings available upon request.

A major benefit of Interface tension links is the option for custom designs in dimensions, ratings, and capacities. The tension links are easy to install and are highly accurate.  They are compact in size and lightweight. Another benefit is the options available, which include standard, wireless, and self-indicating, giving the operator a variety of application use cases for quick measurement readings.  Self-indicating tension links have a built-inaudible alarm, which the operator can set to warn when an applied weight or force is met.

Often, customers will integrate the tension links with an Interface Crosby-styled load shackle for robust applications that require accurate and reliable force measurement for lifting, weighing, hoisting, or towing apparatus requiring safety and monitoring sensors.

Wireless options are growing in acceptance for all types of uses. Interface provides wireless tension links that are compact and reduce the overall product weight based on the casing used to house the small alkaline batteries, which can be easily accessed by removing the telemetry housing cover while the internal electronics remain completely sealed. The antenna is also internally mounted, protecting it from accidental damage during use and handling, which is ideal for harsh environments.

Interface’s most popular tension links include:

WTSATL Lightweight Aluminum Wireless Tension Load Link – The WTSATL series have been designed for lifting and weighing in rugged or harsh environments. Being manufactured from high tensile aluminum to minimize weight also makes them ideal for mobile use (brushed steel holes provide added wear protection from shackles and other applications).

WTSATL-JR Aluminum Compact Wireless Tension Load Link – The Interface WTSATL-JR Aluminum Compact Wireless Tension Load Link series have been designed for lifting and weighing in applications where there is restricted lifting height, but where higher accuracy than can be provided by a load shackle is required. Being manufactured from aluminum alloy to minimize weight makes them ideal for mobile use, and they are also ideal for proof testing and monitoring loads on hoists and rigging, especially in entertainment and events applications.
