Work on the River Rhine for Sennebogen

A Sennebogen 655 heavy duty cycle crawler crane has been put to put to work on the River Rhine in Germany to help carry out lock maintenance repairs.

The crawler is carrying out the work on the Offenbach lock chambers for the Aschaffenburg Water and Shipping Authority (WSA). The Offenbach lock chambers are part of the Main federal waterway, which runs 185.2 km from the mouth of the River Rhine.

In total, 15 locks require regular maintenance. The Sennebogen 655 heavy duty cycle crawler crane is used by the WSA to help carry out regular inspections and repairs of the locks.

The crawler carries out the work, which includes lifting steel plates, from the multi-purpose ferry Muräne. The steel plates are used to hold back the water, so the inspection lock gates can be installed. The plates weigh up to 4 tonnes each and measure between 6 and 9 m long.

The 655 HD was specially designed for use on the ferry, a company spokesperson said. It is driven by a 261 kW diesel engine and has two hoisting winches and a reinforced double-row slewing ring. Plastic pads are fitted on the crawler tracks to protect the ship’s deck, a spokesperson added.

The crane has also been fitted with extras, including an inclination scale to indicate the angle of the ship and the boom. Biologically degradable hydraulic oil is used in case of leakage into the water, a spokesperson added.

Joachim Bauer, WSA crane operator, said, “The machine is reliable, robust and, first and foremost, it is relatively light. This is particularly important on the water – the lighter the machine, the more material we can take on board the multi-purpose ferry. With a variety of special equipment, the machine was adapted to our requirements in the factory.”

Liebherr LR 11350 to lift three coke drums

ALE’s Argentina branch used a Liebherr LR 11350 to lift three coke drums at the YPF refinery in Buenos Aires.

The coke drums weighed 435 tonnes each. ALE was also contracted to transport them, along with lifting derricks, coke drum structures and several other columns and heavy components. To transport the coke drums to the installation area, ALE used four 22 axle lines of conventional trailers.

For the lifts ALE used a 1,350 tonne capacity Liebherr LR 11350 lattice boom crawler crane. To reduce the ground bearing pressure the crawler was set up on load spreading mats usually used for ALE’s AL.SK crane.

Hernán Asensio, ALE project manager, said, “In this project we faced several challenges; working to install such large, heavy coke drums in a small working area filled with obstacles such as trees and buildings. Because of the client’s schedule, the heaviest pieces needed to be lifted during the windy season, which posed another challenge.

“By using the LR 11350 crane with P boom and four configurations, we were able to optimise the manoeuvres in the limited space we had available and minimise the removal of any obstacles. The client was pleased we could provide the engineering solution within the challenging environment.”

This transport and installation of the coke drums took three months to complete.

Tiong Woon adds five Groves

Lifting and transport specialist Tiong Woon has taken delivery of five new 300 tonne capacity Manitowoc Grove all terrains to add to its crane rental fleet.

The Singapore-based company marked the addition of the GMK6300L models in a ceremony held during the Bauma China construction industry exhibition in Shanghai at the end of November. Tiong Woon Crane & Transport, 15th in the IC50 ranking of the world’s largest crane rental companies, now has 18 Groves in its fleet of more than 300 wheeled mobile and crawler cranes.

At the ceremony KH Ang, Tiong Woon chairman, commented, “Grove cranes are very popular units with our customers. When the Grove GMK6300L was launched in 2010 we could see that its onboard innovation gave it capabilities that other cranes didn’t have, particularly with its 80 metre boom. We watched the arrival of the first units in Asia with interest and quickly realised that this crane would be a great solution for many of our customers. It was only a matter of time until we ordered our own, and we saw such strong potential for the GMK6300L that we ordered five units.”

Grove has sold hundreds of units of its six-axle, 80 m boom GMK6300L since it was unveiled in IC magazine in April 2010. Tiong Woon’s other Groves include GMK3055 and GMK5095 all terrains and RT760E and RT890E rough terrains.

Third LTM 11200 9.1 for Max Bögl

German crane group Max Bögl has taken delivery of its third 1,200 tonne Liebherr LTM 11200 9.1 making it six Liebherr crane so far this year.

The new crane features the 100 metre main boom option, which when combined with the luffing jib takes the maximum system length up to 188 metres.

Bögl took its first LTM11200-9.1 in April 2013 and its second in May of this year, the latest unit was recently handed over at Liebherr’s plant in Ehingen.

Peter Guttenberger, director of transport and machines at Max Bögl said: “We particularly use our LTM 11200 9.1 in the wind power industry. They are perfect for erecting hybrid towers”.

The other four Liebherr cranes taken this year include two 45 tonne LTF 1045-3.1 truck-mounted cranes a 100 tonne LTR 1100 and 220 tonne telescopic crawler cranes. The company has also ordered two more LTR1100 crawler cranes for delivery in the first half of 2015.

Sennebogens for AGD

AGD Equipment, the UK and Ireland distributor for Marchetti and Sennebogen cranes, has taken delivery of a 70 tonne Sennebogen 673R crawler crane and an eight tonne 608M multi-crane for its rental fleet.

The 608M multi-crane, mounted on a wheeled rather than a crawler or rail chassis, with closer capabilities to a heavy duty telehandler than a crane, can be fitted with various attachments such as, lifting forks/bucket, hoist, a 4.5 to seven metre telescopic jib and an 800kg capacity work platform. Maximum lift height is just over 20 metres with features including an elevating operators cab and travelling speeds of up to 30kph.

The 673R features a four section 36 metre main boom and an eight to 15 metre bi-fold swingaway extension which can offset by up to 40 degrees. Features include telescoping track width, which retract to three metres, a tier IV engine and Sennebogen’s Sencon control and diagnostics system which offers a clear view of all operating parameters as well as the ability to fine-tune machine performance.

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.
