Sennebogen rolls out colossal crane

March 2016

The latest and largest duty-cycle crawler crane by Sennebogen, a leading German machine manufacturer, is now getting its finishing touches in time for its premiere at bauma 2016, which is billed as the world’s largest construction machinery showcase and scheduled to take place next month in Munich, Germany.

Classified as a 300-tonne machine, the size of Sennebogen 6300 is said to have already wowed visitors who came to a preview at the production plant in Straubing.

Managing Director Erich Sennebogen says: “With the latest Sennebogen 6300, we are creating a duty-cycle crawler crane that will surpass everything that has come before it. Every part has been designed for maximum durability, the base frame is solid steel to ideally absorb forces during continuous use, and we also spared no expense in high-quality, solid components. We are currently expanding our production areas in Plant Two in order to have the organisation required to process future orders.”

Even the transport dimensions is impressive: the duty-cycle crawler crane measures an entire 12 m in length. The crawler tracks alone are 9.5 m long, with a track width of 6.8 m for stability and easy manoeuvrability. The green upper carriage and solid counterweight plates bring the machine to a overall weight of 310 tonnes. Just the upper carriage weighs around 100 tonnes and has to be transported to the trade fair in Munich on a low-bed trailer.

More than 60 years of experience in designing and developing duty-cycle crawler cranes have gone into this project. The extreme hydraulic power, in particular, allows for demanding, dynamic use under extreme loads, for example in dredging, mining and special underground engineering operations. The proven Sennebogen modular concept opens up versatile variants, such as an 80-m main boom that is available for use with lifting hooks. The 6300 duty-cycle crawler crane, with hydraulic power up to 350 bar, a 2,000-litre hydraulic tank and oversized hydraulic lines and valves, is also described as being ideal as a drive unit for hydraulic attachments.
