Each crane has a span of 140 metres (459 ft) and can lift loads of up to 840 tonnes to a height of 70 metres (230 ft). Their combined lifting capacity of almost 1,700 tonnes is one of the largest in the world. Prior to commissioning, the cranes were tested up to 1,000 tonnes, which bent the gantry downwards by over 30 centimetres (12 in).
They also produced a design for a self-erecting tower crane in an era when tower cranes were rare. In the 1960s, there used to be a bridge over the High Street in Lincoln stating that Ruston Bucyrus was the largest Excavator manufacturer in the World.
A tower crane is usually assembled by a telescopic jib (mobile) crane of greater reach (also see "self-erecting crane" below) and in the case of tower cranes that have risen while constructing very tall skyscrapers, a smaller crane (or derrick) will often be lifted to the roof of the completed tower to dismantle the tower crane afterwards ...
Crane The tower crane (see picture) is a modern form of balance crane that is fixed to the ground. A horizontal boom is balanced asymmetrically across the top of the tower. The long arm carries the lifting gear. The short arm is called the machinery arm; this holds the motors and electronics to operate the crane, as well as the concrete ...

The tower cranes delivered concrete to the support cylinders during the continuous pour of concrete to create seamless walls. The Troll A platform has an overall height of 472 metres (1,549 ft), weighs 683,600 tons (1.2 million tons with ballast) [4] and has the distinction of being the tallest structure ever moved by mankind. The platform ...
Giant cranes such as this one are being used to build the world's longest wind turbines. Example of an overhead crane being used to lift heavy rolls. In many instances, the cost of a bridge crane can be largely offset with savings from not renting mobile cranes in the construction of a facility that uses a lot of heavy processing equipment.
