Tower cranes are assembled by mobile cranes. Firstly the main jib is assembled on the ground using small mobile crane. Next the mast is erected using larger mobile crane. Next the counter jib is connected. Then main jib is lifted into place and jib ties connected. Lastly counterweights are lifted up one by one.
Concrete is poured and then the crane is ready to be erected after the curing of the concrete. A 40’ Tower crane base is being set. 16 bolts are installed. The bolts have nuts that are 2 5/16” and are torqued with a hydraulic wrench to as …
How to Set-Up a Tower Crane? Tower cranes are an important tool for construction projects. Thanks to their durability and height, they can easily hoist and transport items.

What are tower cranes and how do they work? Tower cranes are usually assembled up to a certain height by means of mobile cranes. Since the reach of a mobile crane is limited, a tower crane is equipped to build itself by adding columns to its mast. In order to achieve this, a climbing frame …
Tower cranes arrive at the construction site on 10 to 12 tractor-trailer rigs. The crew uses a mobile crane to assemble the jib and the machinery section, and places these horizontal members on a 40-foot (12-m) mast that consists of two mast sections. The mobile crane then adds the counterweights. The mast rises from this firm foundation.

How TOWER CRANES Work? Tower cranes arrive at the construction site on 10 to 12 tractor-trailer rigs. The crew uses a mobile crane to first assemble a 40-foot (12-m) mast that consists of two vertical mast sections and the slewing gear. Then the jib and the machinery sections are assembled.
How is a Tower Crane Erected? To assemble a tower crane initially, a construction crew will use a smaller mobile crane to assemble the jib and machinery. The tower rises from the base and builds itself one section at a time. A top climber or a climbing frame is used for this process. It fits between the top of the tower and the slewing unit.
