Conical bearing designed for amphibious excavators
23 October 2012
Excavators working in water pose challenges. Movements of the excavator and weight transferral resulting from the additional weight when the bucket is full cause various stresses and have an effect on the entire stability of the machine.
ContiTech Vibration Control has developed a conical bearing suitable for the demands of amphibious excavators. Built into the excavator slew bearing, the bearing keeps the amphibious vehicle on course during construction work and can withstand loads of up to 150 kN.
When used as an excavator slew bearing, two separate bearing elements are braced against each other over a rod. Inside, the conical bearing there is a large rubber pad, which provides good lateral stability. And thanks to its high spring stiffness of 2,200 N/mm, the conical bearing effectively reduces any swaying movement of the amphibious construction vehicle.
While the new bearing was specially developed for amphibious excavators, ContiTech believes there are many other applications that would benefit from the new product.
