Switzerland. Canton Ticino. Lugano. Construction Site. Workers are putting together a new crane. A crane is a type of machine, generally equipped with a hoist rope, wire ropes or chains, and sheaves, that can be used both to lift and lower materials and to move them horizontally. It is mainly used for lifting heavy things and transporting them to other places. The device uses one or more simple machines to create mechanical advantage and thus move loads beyond the normal capability of a human. Cranes are commonly employed in the construction industry for the movement of materials. 17.12.2020 © 2020 Didier Ruef
