LAST CALL! SL 50 Top List

11 February 2020

We are now in the final stages of surveying for our eighth Annual 2020 Specialized 50 list which will be printed in our March 2020 edition. This issue will also be on display at ConExpo, so you won’t want to miss out! On this list are companies that provide lifting and rigging services using such equipment as gantries, tower lifts, strand jacks, skates, rigger trucks, SPMTs and the like.

In this list, we rank North America’s largest specialized lifting services companies by their respective ACT index value. The ACT Specialized Lifting 50 index is obtained by adding together the total capacity in U.S. tons of all gantry cranes, strand jack units and other specialized lifting equipment in a company’s fleet.

Please fill out the below form in its entirety and return ASAP to qualify for our 8th annual SL50 list of companies that provide specialized lifting services in North America. Please note that the box for the make model and capacity of your largest specialized lifting unit should be a gantry, strand jack or related lifting device that is not a crane.

Please submit your form to either D.Ann Shiffler at or Hannah Sundermeyer
