The work area of Ruud Thijssen, the driver, is at almost 6 m. He overlooks the Maas river and can intuitively operate his red SENNEBOGEN material handler. Finally, the working weight of almost 80 t and the 19 m long equipment are moved safely and precisely and the SENNEBOGEN 850 with its broad gauge undercarriage is still directly at the quay wall. On a daily basis one grab load after the other lands safely in the hopper, from which the sand is conveyed straight away. Up to 2.75 m³ of sand per cycle is removed from the incoming ships and is later distributed by lorry to construction sites in the area.
With the new SENNEBOGEN 850 from the E series, not only is the most modern technology used for unloading, Kuypers Kessel Beheer B.V. also saves money with every lift thanks to Green Hybrid energy recovery and efficient Green Efficiency engine technology according to a 4-tier standard. With the Green Hybrid energy recovery system, which is used as standard in the large SENNEBOGEN Green Line material handlers, a saving of up to 30 % can easily be made with regards to operating costs. Fitted with a 224 kW diesel engine and approximately 65 kW achieved by the system, the machine has an overall system output close to 290 kW and thus huge savings are made. The operating principle of the recovery is easy and safe - similar to a spring which compresses and decompresses. When lowering the main boom, a third hydraulic cylinder recovers the kinetic energy. Following temporary storage in compressed gas storage tanks in the rear, this energy is available once more for the next lift.
Due to the exposed location directly at the quay, decisive criteria for those who are responsible at Kuypers were above all a comfortable reach depth of up to 7 m to be able to unload incoming ships across the entire ship’s width and also a reach height of approximately 20 m for the hopper feed. Thanks to the broad gauge undercarriage the machine is not only stable but can also be operated at a variable rate along the quay. An additional outrigger is not required. Last but not least, the 850 E comes with a 2.70 m elevating Maxcab comfort cab as standard. From this position, Ruud Thijssen, the driver, also has the best view of his work area.
