Abstract
A lift device, comprising link units and a drive source, for operating these link units, is provided on the top of a vehicle or high surface. The link units comprise a telescoping arm that is disposed in a reclined posture on a top of the vehicle or high surface, a boom that is swung up and down by the drive source, a slide beam that is moved by the swing movement of this boom, along the top of the vehicle or high surface, and arm telescoping means for telescoping the telescoping arm in response to the swing movement of the boom. The telescoping arm comprises a first arm member, having an end that is rotatably connected to a free end of the boom, and a second arm member that is mobile in the lengthwise direction of the first arm member, the first arm member being oriented upwards so as to be lowered while extending from the top of the vehicle, as a result of the swing movement of the boom.
