NLE Calc: Calculate the Recommended Weight Limit and Lifting Index
The NLE Calc is a free Android application developed by the Centers for Disease Control and Prevention. It is based on the Applications Manual for the Revised NIOSH Lifting Equation and is designed to calculate the recommended weight limit (RWL) and lifting index (LI) for single or multiple lifting tasks.
The LI is an index that measures the relative physical stress for performing a specific lifting task, while the composite LI or CLI is an index that measures the overall physical stress for performing multiple lifting tasks. To protect workers from physical stress related to the development of low back disorders, NIOSH recommends an LI and CLI of 1 or less.
The NLE Calc provides a convenient tool for professionals to calculate the RWL and LI, ensuring that lifting tasks are within safe limits. For detailed examples and information on how calculations are performed and what the results imply, users can refer to the Applications Manual for the Revised NIOSH Lifting Equation publication.
