摘要

1. A device for controlling movements of a front or rear attachment of a snowcat. 2.1 Such a device with a built-up of several adjusting cylinders kinematics system, which is by means of a control unit in various functional positions, the pivot movements of the implement about a vertical axis, a transverse axis and a longitudinal axis and a parallel displacement in the vertical direction, is known. 2.2 According to the invention, the kinematic system is additionally designed such that the attachment is translationally and / or parallel displaceable in a horizontal plane in the transverse direction and / or longitudinal direction relative to a vehicle frame of the snowcat. 2.3 Use for snow groomers in snowy areas
