Wet work for TweWe-Bau

Construction company TweWe-Bau put a Sennebogen 673 telescopic boom crawler crane to work on the development of a new slipway in Neuharlingersiel, Germany.

During the first stages of construction, the crawler was used to place 21 metre long sheet pile sections prior to them being driven into the ground at a later stage.

Challenges for the crane include operating in up to one metre of water and working in a tidal environment.

The crane was leased from service and sales partner Tecklenborg Baumaschine. Capacity is 70 tonnes and its full-power boom is 36 m long. The wide-gauge crawler undercarriage allows it work in the water, the manufacturer said. Power comes from a 168 kW emissions level 4 diesel engine.

Sennebogen and Manitowoc launch crawlers

Crane manufacturers Sennebogen and Manitowoc have signed an agreement to produce a series of telescopic crawler cranes at the Straubing location in Lower Bavaria, Germany.

The agreement is for the production of telescopic crawler cranes for the North and South American market. The crawlers will be produced by Sennebogen and sold using the Manitowoc Grove brand name, a company spokesperson said.

The new models include the GHC55, GHC75, and GHC130 telescoping crawler cranes. The GHC series has a compact footprint, which provides excellent manoeuvrability on the job site, a spokesperson said.

Mike Herbert, global product director for rough-terrain cranes at Manitowoc, said, “The GHC series is for customers that need a compact, manoeuvrable crane that can face the rigors of merciless terrain. With minimal transport requirements, 100 per cent pick and carry ability and a telescoping boom, these cranes will prove very nimble in both getting to and navigating job sites.”

The GHC Series cranes are fully supported by Manitowoc Crane Care’s service network. A variety of attachments are available for the models, including an auger attachment and pole claw, ideal for companies working on power line projects.

The Grove GHC55 has a 55 US ton (50 tonne) capacity and 30.4 m main boom length. The total crane length with boom retracted is 10.7 m long and crane retracted width is 3.5 m. It has an overall height of 3.2 m.

The Grove GHC75 has a 77 ton (70 tonne) capacity and 36 m main boom length. The total crane length with boom retracted is 13 m and crane retracted width is 3.2 m. It has an overall height of 3.2 m.

The Grove GHC130 has a 132 tone (120 tonne) capacity and 40.2 m main boom length. The total crane length with boom retracted measures just 15.3 m long and crane retracted width is 3.9 m wide. It has an overall height of 4 m. All three cranes feature Tier 4 final compliant Cummins engines.

Manitowoc will offer services for maintenance, service, spare parts, and financing. The equivalent products from the Sennebogen product range (the Sennebogen 653, 673, and 6113) will not be offered in these sales regions.

The contract was signed in November 2014, with production beginning in 2015.

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.”

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.

Sennebogen 690 HD building road tunnel

A Sennebogen 690 HD duty cycle crawler crane is being used as an all purpose crane to assist construction of an underground road system in Singapore.

Tuksu Engineering & Construction is employing the crane for the Sentosa Gateway Tunnel project, a two-lane one-way road for outgoing traffic from the island of Sentosa, set for completion by the end of 2015.

The 90t Sennebogen 690 HD crane is being used for lifting and loading at the narrow construction site, located adjacent to busy roads.

Sennebogen helps to build bridges in Russia

A Sennebogen 7700 crawler crane has been used to construct an 800m-long motorway bridge in Russia.
The 300t crane was delivered by LLC Lonmadi Saint Petersburg, Sennebogen’s sales and service partner for Russia, to construction company BaltMostStroy in the second half of 2013.

The job included lifting prefabricated steel parts weighing up to 100t onto the concrete foundations of the bridge, which is part of the new A121 motorway being constructed between St Petersburg and Priosersk-Sortavala.

The Sennebogen 7700, which features a 41m boom and auxiliary jib, was required to navigate hilly terrain while lifting the parts perfectly horizontally, and accurate alignment was necessary to securely place the chains and straps. Stability was provided by the 135t ballast and 8m-wide crawler undercarriage of the crane, while lifting was driven by a 313kW Caterpillar diesel engine with two 220kN winches.

Manoeuvrability of the crane is improved by the compact upper carriage, which is the largest component of the 7700 and has a transport width of 3m. The boom sections, which feature a self-assembly system for quick set-up, and the Starlifter undercarriage have a maximum width of 2.43m, making transportation easier.
