Sennebogen handles pipes in Munich

28 June 2019

A 673E Sennebogen telescopic crawler crane from the fleet of Lower Bavarian company Wadle Bauunternehmung was used for underground pipe-jacking work in Munich, Germany.

The crane helped with all the lifting jobs on a 178m underground micro tunneling project being carried out both night and day over 1.5 weeks. The machine was used primarily for unloading the steel reinforced concrete pipes from the delivery trucks and for lowering the drill head into the excavation pit.

"We really value the machine's flexibility in building site applications," said Klaus Gerhardter, Wadle's senior site manager. "Transport is easy, attachments can be fitted quickly and being able to control the variable adjustable telescopic boom via the joystick means that we can react to different tasks on site with very little hassle." 

Wadle's 673 E is equipped with a 36m telescopic boom, a 168kW diesel engine, and hydraulic ballast support equipment for the 17.4t rear-mounted ballast. “The machine can also be used safely and flexibly at inner city locations thanks to its compact size. Loads of up to 70t can be controlled and lifted with ease thanks to the Full-Power boom,” said the manufacturer.

Gerhardter said the personal advice his company received from its service partner IBS Baumaschinen and Sennebogen were very important. The machine has been part of Wadle’s fleet since 2018.
