Derrick cranes are principally suitable for hoisting extremely heavy loads, and are used as stationary installations for the cantilevered construction of steel bridges, the construction of tall buildings with a steel skeleton frame or for special dismantling tasks.
Four kilometres as the crow flies from the Moscow Kremlin, „Moskwa City“ is being built on a 2.5 million square-metre footprint. Landmark of this city will be the Federation Tower with an overall height of 354 m.
On completion, this structure will contain restaurants, a well-know hotel, luxury apartments and offices. The Russian conglomerate Mirax is the main investor and building contractor of the project.
