The world's smallest tower crane
The M40R recovery crane is the world's smallest capacity luffing tower crane. The crane is developed by Marr Contracting with its manufacturing partner Favelle Favco. It is designed to remove other cranes from the top of buildings and has the ability to be placed on almost any roof structure.
Uses include lifting building materials such as air conditioning units and cooling towers but is also often used to recover cranes from the top of buildings during construction. The design places smaller loads into existing support structure and allows for slewing coverage and can also be used to erect larger cranes for heavier lifting.
The M40R was initially used to remove the cranes from the top of the 297.3m tall Eureka Tower in Melbourne, Australia.
