ABSTRACT:
The invention relates to support means, which is for supporting a lateral conveyor adapted for mounting upon a mobile chassis, including a tail section, middle section and at least one head section having pivot points related to the conveyor frame separating said sections from each other. The support means includes a variable length mounting arm comprising at least first and second sections and first and second ends, and means for locking the length of the mounting arm into at least one fixed length corresponding to the length of the conveyor in use. The first end is fixed immobile in relation to the mobile chassis and the second end is fixed immobile in relation to the head section of the conveyor. Also, the support means is configured to provide at least three kinematic pairs, a first kinematic pair being formed by the first section and the mobile chassis, a second kinematic pair is formed by the first and second sections, and the third kinematic pair is formed by the second section and the head section of the conveyor and is provided by a joint, the support means being further configured such that the first, second and third kinematic pairs respectively provide for two, one and three degrees of freedom of movement.
