Super-size me
14 June 2006With China’s immense dam and bridge building programmes, huge cranes are once again popular. Given these continuing demands in Asia, coupled with the West’s growing reconnection with nuclear power, today’s builders of super heavy tower cranes have every reason for optimism.

The era of the super-sized tower crane effectively began some thirty years ago as crane manufacturers responded to the evolving demands of the nuclear power plant building programmes of Europe, the Soviet Union and the USA. Demand was also driven by the needs of the offshore oil and gas exploration industry, and the ever-growing requirements of builders of super tankers in northern Europe and Japan. Chernobyl’s nuclear disaster in 1986 finished off the nuclear ambitions of most countries and with it much of the demand for super-heavy tower cranes. Meanwhile ship building largely completed its move eastwards.

The industry’s new plan proposes that every truck and AT crane will have a new LMI safety system. They will also need to have a data logger – a black box. Although a plan was broadly agreed amongst the industry at Intermat in April, change won't come until the present plan, which is not entirely final, is harmonised across the entire EU - which is expected at the earliest to be 2009. But the change is still radical.
When Edmund Nuttall began thinking about building the new Finniston bridge across the river Clyde, it was soon clear that it would need some heavy equipment. The futuristic steel arch bridge has an unusual oblique form with a single steel arch crossing from one side of the road to the other, part of a strong skew orientation of the whole bridge.
In May 2003, all of the post-Intermat talk was that international public opinion had turned against Intermat, and toward Chinese shows such as Bauma China (this November), or Conexpo Asia (last month). Yet more than 200,000 visitors came to Paris, with the most of the major international manufacturers. Notable absences include Tadano-Faun and Spierings.
A crane accident can cause death and destruction on a frightening scale. That makes comments made by Jeff York, president of US-based operator assistance company Signal-Rite, LLC, even more concerning. He believes there could be devastating consequences if formal verbal communication directives are not introduced to the industry.
