Urea is just one of a wide variety of different materials required to manufacture these products. The new SENNEBOGEN 870 is the main machine used to quickly and efficiently unload materials arriving by ship. The materials are transported for further processing with 23 m banana boom and 6 m³ clamshell grabs via hoppers. Ships of up to 5,000 tons deadweight are unloaded using the SENNEBOGEN 870 within 15 hours, the handling capacity being limited by performance of the conveyor belt on the pier.

Thanks to the modular design of the SENNEBOGEN Green Line product range, customer-specific requirements were optimally met with regard to the rail gantry undercarriage, approx. 5 m pylon and electric motor. The machine was introduced to replace a traditional port crane from the 1950s for which the entire infrastructure was designed. For this reason, the entire space profile of the 870 had to be modified to fit the existing environment. This task was successfully performed in cooperation with distribution partner ScanBalt AB and to the complete satisfaction of the customer.

The operators are particularly impressed by the precise and sensitive controls of the machine weighing approx. 120 t, the high working speed and the extremely smooth running characteristics owing to the electric motor. It also offers an outstanding view from the comfort cab at a height of 14 m, providing the best possible conditions for rapid work processes with a high level of safety. The port cab, which can be moved upward hydraulically to 14 m height, enables the operator to adapt ideally to the relevant situation. The powerful 250 kW electric motor is not only quiet, but also extremely economical, which can result in a 60 % reduction in operating costs compared with a diesel engine. In addition, there is no downtime for refuelling the machine, maintenance costs are considerably lower and the operating life is much longer. A further benefit, particularly in regions with temperatures of around -20° C, is that the electric motor requires no warm-up time and delivers maximum performance immediately and continuously.
