Crane Rental bolsters fleet with five new cranes

Crane Rental Corporation, based in Orlando, Florida, has further expanded its fleet with the purchase of five cranes.

The company added a 275t Manitowoc 999 crawler crane; a 230t Link-Best LS-298 crawler; two 130t Grove RT9130E hydraulic rough-terrain cranes; and an 80t Grove RT880E hydraulic rough-terrain crane.

The move was made in response to “increasing demand in almost every sector of our industry”, said company president Alan Ashlock.

Crane Rental had already expanded its fleet this year, purchasing cranes including a Peiner SK415 tower; a 660t Manitowoc 18000 crawler; a 600t Terex AC 500-2 all-terrain hydraulic truck crane; and a 275t Grove GMK 5275 all-terrain hydraulic truck crane.

Potain helps Lyon reach new heights

Two Potain tower cranes are being used to construct what will be the third-largest building in France.
At 200m high, the Tour Incity will be the tallest building in Lyon when completed, and will comprise 44,000 sq m of offices as well as four restaurants.

The project’s main contractor Bouygues erected two of its Potain tower cranes at the site: a 16t MD 550 top-slewing crane using 60m of its 80m jib, and a 12t MDT 222 topless crane using 30m of its 65m jib.

The cranes are operating for 14 hours a day, building one floor a week over 30 months and climbing 15m a month, to final working heights of 280m.

The schedule has been imposed due to the inner-city location, with a busy road, school and shopping mall all adjacent to the site.

The demands of the location also led to Bouygues climbing the MDT 222 internally, using a floor climbing system involving a frame attached the building’s concrete core. The MD 550 is installed with Potain’s external anchorage system, with frames fixing the mast to the outside of the building.

Julian Bargues, job site manager at Bouygues, said: “Working in such a tight space means we need very precise load control and smooth movement, two things we know Potain cranes are ideal for.”

Zoomlion acquires Dutch hoist manufacturer

Zoomlion’s tower crane division has extended its material handling hoist business with the acquisition of the Netherlands’ Raxtar.

Nearly 200 people attended the signing of the agreement at Shanghai’s Jin Mao Tower on August 8.
Zoomlion vice president He Wenjin said the acquisition showed Zoomlion’s “complete confidence” in the future of the Chinese and international construction machinery markets and its commitment to the strategy of helping Chinese machinery “go global”.

Raxtar’s products include material and passenger hoists, transport platforms and industrial lifts, with products used in benchmark projects such as the World Trade Center in New York.

Zoomlion said the acquisition would mean benefits to both companies, including improvement of the product spectrum, development of an international strategy and accelerating mergers and acquisitions.
Tang Shaofang, deputy general manger of Zoomlion’s hoisting machinery division, said: “This acquisition will bring in international advanced technology, which will improve operational performance, enhance service value and reduce lifting costs, thereby meeting customer requirements for increasing value an reducing costs.”

Raxtar said the partnership would help Zoomlion improve its products and brand impact, as well as provide its global customers with new construction hoist and vertical lift solutions.

New Zoomlion-Jost flat top targeted at Chinese market

Zoomlion-Jost flat top tower cranes are to be promoted on the Chinese domestic market following successful sales to international markets.

Since purchasing flat-top tower crane technologies from Jost Cranes GmbH Pte Ltd and subsequent development of the Zoomlion Jost T320-16, shown at Intermat 2012, another crane – the T8030-25U has been launched and will also be promoted in China.

Zheng Changming, a Zoomlion director, said: “The four series of products working with Jost have not been promoted at the domestic market. Now we are working on tower cranes which suit the domestic market and developing the T8030-25U and a subsequent two models, redesigning Jost products, to lay a solid foundation for future markets.”

The T8030-25U features a maximum lifting moment of 4925kNm and is designed for high-rise construction, bridge-building and power projects.
Subsequent models will also be promoted on the domestic market.
Zoomlion-Jost flap top tower cranes have already been exported to Europe, Singapore and Hong Kong.

Wolffkran provides answer on cramped construction site

A requirement for tight manoeuvring on a cramped construction site in Munich’s old town led German contractor Riedel Bau GmbH & Co to hire a Wolff 166B B luffing jib tower crane from Wolffkran.

The design of the 166B, with hydraulic luffing gear, means the jib can be raised in a near vertical position, which proved imperative on the Maximiliansplatz office development project surrounded by other construction sites and cranes.

Norbert Zährl, Riedel site manager, said: “Because of its design, the Wolff can slew in the minimum of space without projecting beyond the site, meaning we can work without any danger of collision.”

The 166B, able to lift 12t in the two-fall operation, was used to lift concrete and other structural components. Its tip load capacity is 3.4t with a 45m jib and the maximum lifting speed is 87m/min.

Wolffkran said the luffing crane could be erected on a lower tower height than with a saddle jib crane, saving additional time. Crane erection took just one day.

Rocketing property prices and the popularity of Munich’s old town meant the office project was fully leased even before construction began.

Zoomlion Jost Flat-top tower crane launched

The first Zoomlion Jost flat top tower crane has been launched: the T8030-25U. A project team based at the Chinese manufacturers research centre in Germany developed the crane.

The flat top tower crane T8030-25U has a maximum lifting moment of 4925kN/m. The firm said that the design philosophy was to optimise the design of major structures, including crane top, crane boom, crane boom pull rods, climbing frame, upper and under bearing, cab, and improving the safety of components, including platform, handrail, connecting screw rod and safety rope in crane boom.

Zoomlion said that it hopes the tower crane improves the sale in the overseas high-end areas including European countries, Singapore and Hong Kong through the application of German technology.
