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 Link series is manufactured from high tensile aluminum and stainless steel. Matched to shackle sizes, the load links have a rugged design for uses 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 light weight. 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 can be set by the operator 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 used for lifting, weighing, hoisting or towing apparatus that need sensors for safety and monitoring.

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.

Load Shackles 101

A load shackle is a u-shaped, load-bearing connecting device designed to be used with a removable pin. Load shackles can be used in a number of different rigging and load securement applications to provide sensor technologies in the connection of different types of lifting slings, chains or ropes to an object or to each other.  A load shackle is essentially the installation of a load monitoring pin into the shackle body allowing you to replace existing rigging hardware with a load cell for force measurement and weighing data.

Load shackles are rugged in design and are used to provide accurate and reliable measurement of tensile loads, as well as support applications for harsh and challenging environments. The industries that most regularly take advantage of our load shackles include industrial, aerospace and defense, agriculture, and construction. Applications for lifting, moving and weighing objects can be monitored as well as optimized for performance using load shackles. They are often designed into engineered structures or for use with cranes, winches or other robust lifting mechanisms.

Interface offers a wide variety of load shackle designs for different environments and force measurement needs, ranging from 2.2K to 2205K lbf. Our load shackles come in both cabled and wireless, as well as environmental resistance options including flameproof and IP67. Visit our overview here.

Load shackles come in many standard shapes and sizes, including customization options to meet a specific design or use requirement. Some of our shackles are exclusively designed to meet the needs of applications in hazardous environments like the oil and gas industry, or marine industry where they’ll be submerged in water during testing and for continuous use, or in areas with high heat and flames. Some of our most popular load shackles are listed below:

WTSSHK-B Wireless Crosby™ Bow Load Shackle  – Suitable for use in a wide range of industrial and marine weighing applications, these load shackles are robust, reliable and easy to install. The unique telemetry housing is manufactured from tough high-performance polyamide resin making it strong yet light, resulting in a better-balanced load shackle when compared to others available on the market.

ISHK-B Bow Type Crosby™ Cabled Load Shackle – The Interface range of ISHK-B load shackles are designed for lifting and weighing in rugged or harsh environments, including submersible applications. The shackle pins are forged from high tensile stainless steel to 6.5 MT (14.3K lbf) and high tensile carbon steel from 9.5 MT (20.9K lbf), and are machined to an exacting specification. The basic shackle uses the Crosby G2130 (1 to 25 MT / 2.2K to 55.1K lbf), G2140 (40 to 120 MT / 88.2K to 265K lbf) and GN Rope H10 (150 to 1K MT / 331K to 2205K lbf).

Flame Proof Bow Type Crosby™ Cabled Load Shackle – The Interface range of flameproof load shackles is designed for lifting and weighing in rugged or harsh environments, and also meet the requirements for operation in Zone 1 and 2 hazardous areas. The shackle pins are forged from high tensile stainless steel and are machined to an exacting specification. The basic shackle uses the Crosby G2130 (1 to 25MT or 2.2K to 55.1K lbf) and G2140 (40 to 400MT or 88.2K to 882K lbf) series.

Load Shackle Application:

Load shackles are commonly used in the construction industry to measure heavy machinery. For cranes outfitted with a lifting attachment such as a claw, a tension sensing load shackle is used on the pulley mechanism to measure the weight lifted by the crane. The tension sensor can provide real-time data to the construction crew to help monitor the lifting process and provide the operator with the information necessary to refrain from lifting weights that are too heavy for the crane to handle. If the claw arm lifts more than the crane is able to withstand, the attachment could break off, or worse, the crane could topple over.

In a recent example, Interface’s customer used a WTSSHK-B Wireless Load Shackle connected to load-bearing strings and a WTS-BS-1-HA Wireless Handheld Indicator to gather data. The customer was able to successfully lift and read the weight (wirelessly) on a handheld display while the material was being relocated.
