ATEX-Certified Offshore Crane Load Monitoring Solution for Safety

Product Description

⚙️ Load Moment Indicator (LMI), also known as a safe load indicator or crane computer, is an essential safety device installed on various crane types, including mobile, crawler, tower, gantry, portal, marine, and offshore cranes.

It alerts operators if a lift exceeds the safe operating range and can physically lock out machinery in unsafe circumstances to prevent accidents.

Product Description

The system controls lifting equipment to function according to the manufacturer's suggested safe load charts. Key parameters such as load weight, working radius, control limit, boom angle, and extension are displayed clearly in the operator's cabin.
