Abstract
A method of installing and removing concrete blocks involves using handling device that is equipped with means for attaching and suspending a concrete block and which itself comprises a protective barrier placed temporarily on the concrete block to safeguard the operations of detaching or attaching this block. The barrier advantageously has safeguarded lateral access of the safety bow type that comes into register or alignment with rungs with which the concrete blocks are equipped. The method keeps an operator safe while installing and removing stackable concrete blocks, particularly an operation in which the concrete blocks are stacked on a base chassis of a tower crane.
