Motorized lifting machine for lifting e.g. load, to desired position, has telescopic supporting arm articulated on frame, where frame includes four arms independently pivoted centrally of frame, and each arm includes hydraulic wheel-motor
摘要
<p>The machine has a frame (1) mounted on wheels (4), and a telescopic supporting arm (2) articulated on the frame about a horizontal axis (3). The frame includes four arms (5) independently pivoted centrally of the frame, where each arm of the frame independently includes a hydraulic wheel-motor at its distal end. The horizontal axis for the articulation of the support arm is provided at an end of a support that is articulated on the frame, so as to define a space of visibility for an operator working in an operator's cab.</p>
