The newest and largest Sennebogen balance materials handler is now handling bulk goods at Bulgaria’s largest Black Sea port, Burgas.
The 270t Sennebogen 8400 EQ leverages an innovative balance principle that, when combined with the machine’s electric drive, can save up to 75% in operating costs compared to traditional equipment of similar size, said Sennebogen. It has a reach of more than 40m, and is operated from a cab elevated to a height of about 20m.
Equipped with a rail gantry undercarriage, the 8400 EQ easily moves up and down the Port of Burgas’s docking platform. Local trucks simply drive under the materials handler for fast loading.
The first 8400 EQ was initially assembled at Sennebogen’s plant in Straubing, Germany. In a tandem lifting operation, two cranes were used to place and then secure the upper carriage and boom elements. Sennebogen said that intensive factory testing followed, before the machine was dismantled into 36 indi vidual parts for transport to Bulgaria. The 36 parts were carried along the Danube aboard the 1,200t river boat that travels regularly from Straubing toward Ruse in Bulgaria.
Now in operation, Sennebogen said the 8400 EQ is receiving positive feedback for its production and efficiency, including the energy-savings resulting from the electric drive and balance principle.
“Incorporating the principle that the longer the lever is on one side, the greater the opposite counterweight must be, the 8400 EQ is able to retain perfect balance, and put all energy into handling the load,” the crane maker stated.
“Despite its massive size and unique design, the gantry-based balance materials handler has proven easy for operators to manoeuvre, thanks to the dual joysticks in the elevated cab.”
