Sennebogen 653 E Supports Munich U5 Extension at Pasing
30-Second Takeaway
A 50-tonne Sennebogen 653 E telescopic crawler crane has been working for around nine months on the extension of Munich’s U5 underground line at Pasing station. The project is building a new underground station approximately 400 metres long, with construction taking place around 25 metres below ground beside an active railway station and busy road. The crane handles reinforcement cages, drilling equipment, pipes and other materials for bored pile and diaphragm wall work. A 200-tonne Sennebogen 5500 crawler crane joined it for heavier lifts, including reinforcement cages weighing up to 35 tonnes.
Crane Supports Foundation Work in Confined Site
ARGE U5 West 2, comprising Wayss & Freytag, Max Bögl and Züblin, is constructing the new underground station beneath Pasing station. The work is taking place in a tightly constrained urban environment, alongside operating rail services and heavily trafficked roads.
The 653 E has supported both bored pile and diaphragm wall construction. Its duties include lifting six-metre drill pipes measuring 1.5 metres in diameter, tremie pipe boxes, pumps, smaller machinery and reinforcement cages. It also unloads and repositions materials around the site, working alongside drilling rigs and specialist foundation equipment.
The crane’s compact crawler configuration allows it to manoeuvre through restricted work areas. Remote control gives operators the option to leave the cab and choose a better view when positioning loads close to other machinery.
Two Cranes Divide the Lifting Work
For heavier lifts, a 200-tonne Sennebogen 5500 crawler crane was brought in alongside the 653 E. The larger crane installed reinforcement cages for the diaphragm walls, handling loads of up to 35 tonnes and working at longer distances.
The cranes had separate roles: the 5500 handled the heavier diaphragm wall lifts, while the 653 E took on lighter, more frequent lifting tasks in the most restricted areas. After the major diaphragm wall lifts were completed, the 5500 left the site. The 653 E remained as construction progressed.
The Sennebogen 653 E has a maximum lifting capacity of 50 tonnes and a four-section Full-Power Boom that telescopes from 9.4 to 30.4 metres. Sennebogen lists a maximum hook height of 43 metres for the model. The crane’s telescopic boom and crawler undercarriage support lifting and material movement on construction sites where access and space are limited.
About Sennebogen
Sennebogen is a German manufacturer of cranes and material handling equipment, with product lines that include telescopic crawler cranes, mobile telescopic cranes, port cranes, material handlers and duty-cycle crawler cranes. The 653 E is part of its telescopic crane range. Its Full-Power Boom can be telescoped hydraulically, while the crawler undercarriage is designed for manoeuvring on construction sites and supporting pick-and-carry work.

Frequently Asked Questions
What is the Sennebogen 653 E doing on the Munich U5 project?
It is supporting bored pile and diaphragm wall construction by lifting reinforcement cages, drill pipes, tremie pipe boxes, pumps, smaller machinery and other materials. It also unloads and repositions equipment around the site.
What are the Sennebogen 653 E’s main specifications?
The 653 E has a maximum lifting capacity of 50 tonnes and a four-section Full-Power Boom with a telescoping range of 9.4 to 30.4 metres. Sennebogen lists a maximum hook height of 43 metres.
Why were two different crawler cranes used?
The 200-tonne Sennebogen 5500 handled heavier diaphragm wall lifts, including reinforcement cages weighing up to 35 tonnes and lifts over longer distances. The 653 E handled lighter and more frequent lifts in the site’s more restricted areas.
What makes the Pasing construction site challenging?
The new underground station is being built around 25 metres below ground beside an active railway station and a heavily trafficked road. The confined urban site requires lifting and foundation work to be coordinated around limited working space and other equipment.
How long has the 653 E been working at Pasing?
The crane had been on the project for around nine months at the time of the report and remained on site after the Sennebogen 5500 completed its heavier diaphragm wall lifts.
