10 Terex E-RTGs for China

Chinese port operator Ningbo Port has ordered 10 Terex E-RTG rubber tyred gantry cranes for its Yuandong Terminal.

Manufactured at Terex Port Solution’s facility in Xiamen, China, the 40 tonne electric E-RTG variant cranes have an under spreader lift height of 18 metres and are able to stack containers one over five. They have a span of 23.47 metres allowing them to cover six rows of containers as well as a truck lane.

Ningbo took delivery of its first 12 Terex rubber tyred gantry cranes in 1999, back when it only operated two terminals. Today it has a fleet of 167 RTG cranes operating from seven terminals. There is also a Terex Port Solutions service centre located in the Port of Ningbo.

Ningbo Port president Jinkun Wu, said: “RTG cranes from TPS are highly productive, and the first 12 units are still working reliably in our Port Beilun terminal. The fact that we have permanent and exclusive access to the proactive and efficient TPS service team, as well as to spare parts, has helped us to keep the availability of our cranes as high as possible.”

Terex CC 2800 crawler used for erecting wind turbine

A Terex CC 2800-1 crawler crane purchased by German crane company Mobi-Hub was taken directly from the manufacturing facility to a wind turbine erection site in a forest in Koblenz.

The crane was taken from Terex’s manufacturing facility at Zweibrücken to the Koblenz site, where the wind turbine was erected for Enercon.

The turbine had a hub height of 130m and required three main lifts, covering the 48t nacelle, 71t generator and finally the 68t rotor.

The CC 2800-1 was set up with a 138m S7 boom with 12m fixed jib, and 180t of counterweight.

Challenges included navigating a narrow access path to the site, which was located in a forest, and assembling the boom on sloping terrain which limited the positioning of the assist crane.

Frank Strempel, head of large cranes at Berlin-based Mobi-Hub, said: “On top of that, we had to use the suspended superlift tray with a weight of 325t when erecting the boom.”

The team of six assembly technicians from Mobi-Hub, assisted by Terex service technicians, completed the assembly of the crane in two days.

Terex has introduced its 130t Explorer 5500 all terrain crane

Terex has introduced its 130t Explorer 5500 all terrain crane, designed to be the company’s most compact crane in its capacity class.

Part of the Explorer range which also includes the 5600 and 5800 models, the new 5500 features a 60m main boom with three extensions of 11m, 22m and 33m, with a maximum system length of 86.5m.

With a maximum load moment of 395mt, the five-axle crane is designed to be compact enough for use in cities and on other narrow construction sites. Manoeuvrability is improved by steerable axles, says Terex.

Features including variable axle loads and axle pair intervals, as well as dismountable main boom, enables the crane to be fulfil road service approval regulations in key markets.

All the components for the Explorer 5500 can be transported on one standard support vehicle, and the crane also incorporates Terex’s single-motor concept as used on the 5600 and 5800 models. This automatically adjusts the power usage according to whether the crane is driving or operating, reducing energy consumption.

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.

Pressing issue solved by Terex Superlift

Three press components each weighing at least 200t have been lifted out of a factory in Germany using a 650t Terex Superlift 3800 lattice boom crawler crane.

Crane company Viktor Baumann employed the crane to lift two 270t components and one 200t components from an SGL Carbon facility in Bonn, at a working radius of 26m.

The Terex crane was assembled by a team of five at the SGL premises, using a 220t assist crane. It was set up with an SSL configuration, a heavy 48m main boom, and a 36m SL mast. 165t of counterweight was used on the crane’s superstructure, with 320t on the SL counterweight tray.

Terex crane meets space challenges in factory

A Terex Challenger 3160 all terrain crane has helped a salt and fertiliser manufacturer overcome space restrictions and the highly saline atmosphere in its factory.

German mobile crane company H & S Autokrane used the Challenger at the facilities of Kassel-based Kali- und Salzwerke to install and remove pipelines.

The three-axle, 55t Challenger 3160 features a 50m boom system which met requirements of the project including hoisting pipelines and steel elements 42m for assembly into an existing structure, and hoisting with a wide radius for moving underneath pipeline bridges.

The crane overcame various complications during the project including navigating a narrow approach, which at some points allowed a width of 2.6m and a height of 3.6m. Drains passing underneath the workspace limited the weight for the job to 40t, as well as restricting the use of half of the outrigger extension for parts of the project while still requiring the full counterweight.

Jens Hartung, field crew member at Hesse-based H & S Autokrane, said: “We were able to master even this task with our Challenger.
“To work here, a crane needs to be really small when it pulls in, and large with a long boom in the structures. Moreover, it needs to be able to lift heavy loads. The Challenger 3160 all terrain crane comes the closest to fulfilling this ideal.”
