What is Smart Sling?

Planning and executing a critical lift is tough. Your crane is in position and it’s time to begin the lift – you need to know that every detail is going as planned and that your people are not in danger. Mistakes happen – loads shift, human error and shock loads occur. With Smart Sling, you can monitor your rigging in real time and you are immediately alerted to critical overloads that would otherwise endanger workers or cause a catastrophic accident.

Smart Sling® Technology is engineered from the ground up for the overhead lifting industry. A proprietary radio frequency protocol was designed for maximum reliability. Custom computer hardware and software was developed with input from lifting professionals throughout the development process. Smart Sling gives you peace of mind without over complicating your lift.

Smart Sling Technology constantly monitors your Twin-Path® high performance sling for severe overload. If an overload is detected, an alert is immediately sent to users. Smart Sling is a hybrid system, combining digital and mechanical technologies to create a solution that is accurate and does not rely on latency or refresh rates. Inside your Smart Sling there is a weak link, independent from the load-bearing core yarns, that reacts when the sling is overloaded. This indicates that the sling may have experienced a load significantly higher than its rated capacity and a repair evaluation is needed.

Alert history

Mistakes happen. In order to know what went wrong, you need to know what happened and when it happened. Smart Sling creates a record of which slings were overloaded and timestamps when. Notes can be added to each sling to keep all users informed of the sling status.

The Sling Overload Sensor is embedded inside every Smart Sling and is constantly monitoring for overload. Featuring a two year always on battery, there is no need to turn Smart Slings off or charge between uses. With Smart Sling, complicated external load measurement devices are no longer needed.
