Foundation Engineering: SENNEBOGEN 6130 HD duty cycle crawler crane at AUG. PRIEN

As part of the HafenCity project currently the new Elbbrücken quarter is being created in Hamburg. The tradition-rich company, AUG. PRIEN, founded 1873 in Hamburg-Harburg, won the contract for implementation of the construction measure, "Kaimauer Elbbrücken center west with filling". Over a length of 160 m the areas will be enclosed and safeguarded against water via a mixed sheet pile wall.

The new SENNEBOGEN 6130 HD, which was delivered to AUG. PRIEN mid-2013, goes into special implementation as one of the first deployments. Since February 2014 the duty cycle crawler crane has been working on the company's pontoon installing the king piles. Because the freeport Elbbrücke (Elbe bridge) is in the direct vicinity, installation via conventional ramming was not possible, due to the vibrations for the sensitive caisson foundation of the bridge, it was necessary to find alternatives. In a complex procedure the ground is pre-bored, cleared and then the piles are positioned. Whether the task at hand is placing pile planks, which weigh several tons, or conveying the cleared material to land, the 6130 duty cycle crawler crane is the equipment of choice.

In this regard, the duty cycle crawler crane is equipped with a powerful 354 kW Caterpillar diesel engine and two powerful 250 kN freefall winches. Thanks to the 5.50 m broad-gauge undercarriage the crane is particularly stable. For the operator, the comfortable maXcab, which can be inclined 20 degrees, not only offers an ergonomic work environment, four additional all-round cameras ensure an optimal all-round view of the work area. Currently AUG. PRIEN is only using the machine as a crane on the pontoon. However the SENNEBOGEN 6130 HD has also been designed for use with a 42 m Delmag hanging leader, MH 39107.
