The HS 8100 HD is successor to the HS 855 HD, the most popular model of the Liebherr series of duty cycle crawler cranes. It is installed with a 390 kW/530hp Liebherr diesel motor. The duty cycle crawler crane impresses, on the one hand, due to its excellent level of working safety thanks to additional walkways and ladders, and on the other hand, due to its optimized hydraulics and the Eco-Silent Mode, which has an extraordinary efficiency under tough jobsite conditions. With the aid of the Eco-Silent Mode, the speed of the motor can be reduced to a required predefined level. This leads to a considerable reduction in the fuel consumption, and at the same time, a reduction in noise emission.
During operation with the hydraulic slurry wall grab from Leffer, the HS 8100 HD requires a mere 16 litres of diesel per hour. Furthermore, using the hydraulic slurry wall grab, the work can be carried out more precisely over the whole depth than with a mechanical slurry wall grab.
Multibillion Project at the Suez Canal
The construction of the tunnels is part of an Egyptian infrastructure project with immense dimensions. New tunnels are not only being built at Port Said but also further south at Ismailia. The project also includes the widening and deepening of the existing shipping lane of the canal, as well as the construction of a completely new lane with a length of approximately 35 kilometres in the northern section. The total investment volume amounts to approximately 4 billion US dollars.
