Abstract: A cabin suspension system, adapted to be used in a forestry vehicle, comprising an operator cabin, adapted to control the forest vehicle, spring dampers, mountable between the operator cabin and a vehicle frame, magnetorheological dampers, mountable between the operator cabin and a vehicle frame, sensors, adapted to detect velocity and/or acceleration and/or movement of the cabin, of the vehicle frame and a dampening coefficient of the magnetorheological dampers, and a controlling unit.

Abstract: The apparatus includes a positioning unit and an alignment unit. The positioning unit extends across the elevator shaft in a second direction and comprises at each end a first attachment mechanism movable in the second direction for supporting the positioning unit on opposite wall structures in the elevator shaft. The alignment unit extends across the elevator shaft in the second direction and is supported with support parts on each end portion of the positioning unit. Each end portion of the alignment unit is individually movable in relation to the positioning unit in a third direction perpendicular to the second direction. The alignment unit includes further at each end a second attachment mechanism movable in the second direction for supporting the alignment unit on opposite guide rails in the shaft. The second attachment mechanism includes a gripper for gripping on the guide rail.

Abstract: Example embodiments relate to an apparatus including a stationary first part, a movable second part, and a link arm mechanism connecting the first part and the second part. The first and the second link arm may be interconnected with a fifth articulated joint. First ends of the link arms may be connected with articulated joints movably on the first part. Second ends of the link arms may be connected with articulated joints on the second part. The second part may be moved with a first actuator in a first direction, with a second actuator in a third direction and with a third actuator in a fourth angular direction around the fourth articulated joint.
