200 t of gravel per hour
On January 28, 2025, the new SENNEBOGEN 855 E Hybrid was officially put into operation at the Vienenburg gravel plant. Since then, the material handler has taken over primary gravel extraction at the site – with outstanding results. Equipped with a powerful 237 kW diesel engine, a 21-m equipment length, and a 2.45 m3 bucket, the machine achieves remarkable performance: up to 200 t of gravel per hour and 1500 t/d in single-shift operation. This means the new material handler outperforms a comparable duty cycle crane with clamshell bucket.

Half fuel consumption – 72 t of CO2 savings
Particularly impressive is the low fuel consumption: despite the demanding task, the 855 E Hybrid consumes only about 24 l/h – around 60 % less than its predecessor. This saves August Oppermann GmbH around 72 t of CO2 annually. In addition to the efficient engine, the SENNEBOGEN Green Hybrid recuperation system contributes significantly to reducing consumption. When the boom is lowered, an additional hydraulic cylinder combined with nitrogen piston accumulators stores energy, which is then reused for the next lifting movement.

Optimized for gravel extraction
The new material handler has been specially designed to meet the requirements of gravel extraction. Its crawler undercarriage ensures both secure stability on loose ground and maximum mobility within the plant. With its long equipment, the SENNEBOGEN 855 E Hybrid achieves a working depth of up to 12 m – ideal for dredging gravel.
The Maxcab operator cab can be raised hydraulically up to 3 m and offers the driver optimum visibility in every situation. Equipped with armored glass, it guarantees maximum safety. Sun blinds, Bluetooth, DAB radio, and modern air conditioning provide additional comfort.

Intuitive operation – no training required
The machine also impresses in terms of user-friendliness: thanks to its intuitive joystick controls, no special training is required – any excavator operator can control the 855 E directly.
Reliable partner: Schlüter Baumaschinen
August Oppermann GmbH was supported in acquiring the new material handler by SENNEBOGEN’s sales and service partner Schlüter Baumaschinen. Karsten König, Managing Director for Technology and Mining, expressed his satisfaction: “We received excellent advice throughout. At every stage of the process, we had a knowledgeable contact person at our side. Our long-standing collaboration with Schlüter is of great importance to us and has proven extremely valuable.”
