Abstract

A debarking device includes a drum having a radically outer peripheral surface, the drum being arranged to be rotated about a longitudinal axis. Two bogies, spaced from one another in the circumferential direction of said outer peripheral surface of said drum support the drum from a foundation. Each bogie includes a travelling wheel and a driving wheel, these being spaced from one another in the circumferential direction of the outer peripheral surface of the drum, and each journalled on respective axles for rotation about a respective axis which is substantially parallel to the longitudinal axis. A respective structure is interposed between each said bogie and the foundation, and supports the drum supported by the respective bogie on the foundation. Each structure includes three elastic elements each having a respective cushion. The cushions are located beside one another in the circumferential direction, with spacing therebetween, so as to include an intermediate cushion and two outer cushions. The intermediate cushions are more rigid than said intermediate cushion. Each structure further includes a plate arrangement supporting a respective bogie and being supported by the cushions of a respective three elastic elements.
