For a good three years now, the Weng Group has been successfully using a , a machine that is not an everyday occurrence in this work area, for its demanding problem tree felling operations. Developed with the appropriate reach height and load capacity, the 830 also cuts a fine figure as a felling machine. We meet the two brothers Torsten and Marco Weng on a wet and cold January day along the A44 freeway, where the task today is to fell numerous diseased alders and American oaks dangerously leaning into the roadway over a total length of around 1 km.
"Our time window for this work is very limited. We are only allowed to enter this area between 9:00 a.m. and 2:30 p.m.; from 3:00 p.m., when rush hour traffic starts, the road must be completely clear again," Torsten Weng explains one of the challenges.
The three men in the felling troop are used to the traffic that rushes past them in the direction of Essen. While Torsten Weng steers the material handler and safely puts down the large trees overgrown with ivy, his two colleagues Stanislaw Sawada and Grzegorz Jacek make sure that everything around the trunk is exposed. Piece by piece, the trees, which are up to 16 m high, are removed in a controlled manner. The last cut is made by the man at the chainsaw, because the cutting head has to be protected from stones and debris so close to the ground. In order not to obstruct the traffic too much, only the hard shoulder and the entrance to the highway are closed. The traffic can continue because the trees are removed and deposited in a controlled manner.
"The SENNEBOGEN 830 offers us everything we need for our daily challenges. Thanks to its long reach of over 17 m, we can safely reach even the most distant trees and work on where others reach their limits. With the comfortable load capacity of around 4.5 t at 10 m reach, for example, and a high hydraulic power, we can also operate large attachments safely and reliably".
The SENNEBOGEN 830 E itself is equipped with a 168 kW diesel engine with exhaust gas level 4 and can reduce its track width from 3.80 m to 2.30 m for transport by means of the telescopic undercarriage. Driver Torsten Weng always has an optimum view of his working area from the cab, which can be raised by 2.7 m and tilted by 30 degrees, and is also optimally protected at his workplace with FOPS protective grids and bullet-proof glass.
For about 10 years the Weng brothers have been pioneers in road and tree care. Whereas in the past, the company's activities also included the felling of individual problem trees and the maintenance of greenery, today Weng specializes in roadside greenery along freeways and expressways. Thanks to an extensive machine park with several excavators, shredders and tractors, the felled material can usually be shredded and disposed of or recycled directly on site.
The company also takes care of machine transport and shut-off measures itself, thus offering an all-round service from a single source. So it is no wonder that Weng has numerous annual contracts with the communities around the Ruhr metropolises to manage the growing stock of trees and greenery. In addition to the large SENNEBOGEN 830, Weng also has a with 11 m reach and an with 14 m reach for tree felling.
"The quality and reliability of the SENNEBOGEN machines convinced us completely. We have to work quickly and efficiently on our jobs, we cannot afford downtime. The good service and support provided by the here in the Ruhr area also helps us in this respect," summarises Torsten Weng.
