Lift Planning Tools

The ALLMI Lift Planning Calculator has been developed for trained and competent Appointed Persons, to assist in the lift planning process through the quick and easy calculation of critical figures.

Once basic loader crane data has been entered, the tool includes the calculation of: stabiliser loadings; pad sizes for a given ground bearing strength and the subsequently imposed loads; rated capacity utilisation percentages; permissible wind speeds for operation given the sail area of the load; and sling section for one, two and four lifting point loads. The tool then automatically populates results of the calculations into text that can be copied directly to a lift plan set out in the ALLMI recommended format.

Disclaimer: This tool is for guidance only. It should be studied and the information applied with the assistance of expert advice as necessary. Every effort has been made to ensure the accuracy of the information provided, but no legal liability can be accepted by ALLMI for any errors or omissions, nor for any consequences thereof.
