ABSTRACT:
The invention concerns a material transloading equipment unit with an undercarriage and a turntable connected with this undercarriage by means of a track ring, on which an arm that can be pivoted by means of at least one hoisting cylinder is pivot-mounted. According to the invention, on the one hand at least one additional pivot point for the arm is provided on the turntable and/or on the boom foot, and at least one additional pivot point is provided in the arm or in a pivot plate on the arm. This allows a number of possible combinations for the kinematics of the arm.
